I'm currently using a regular usb cable to charge my phone directly from my car stereo while driving. The problem is that it takes close to an hour for the battery charge to increase 10% when I'm streaming pandora through bluetooth and using the phone's GPS. I'm assuming that the usb port in my stereo is only capable of putting out 500ma, if not less. Curious to see if anyone knows whether a DC to micro usb cable would give me a faster charge (1000ma). Thanks in advance.
BEst one ive ever used is the official palm one for the pre or pixi. Completely charges the evo from dead to full in about an hour while on the road on a call via bluetooth. Seriously good, verified a while ago on the precentral.net forums that its 1000 mA. They are only like 15 bucks at best buy, or maybe even less on amazon.
Go to amazon or google and search for 12V 1Amp USB charger and that should give you exactly what you need...I use a 1Amp charger for all my devices and works just fine...1 thing to note, that if you have time to use a 500ma charger, let it do it, a little bit slower charge will extend the life of the battery(not necessarily run time, but the length of time the battery will hold as good of a charge).
I use the one below. Works pretty great..5V/1A, exactly what you'd need. The thing says iPod, but it can be used for any USB charged device. An extra nice feature of this charger is that it sits nearly flush with the dash of your car

Cool, thanks for the responses guys. I ended up going with the palm pre charger from amazon, a little pricey at $20, but that's the best deal I could find for it. I'd rather pay a little more than get one that will crap out on me in a month. And it terms of a slower charge (500ma) being more beneficial for a longer battery lifespan, I'd rather dish out $10-$15 in 6 months or so for a new battery than to have to deal with this ridiculously slow charging time
Another option for 1A (1000mA)...
Not to resurrect a dead thread, but I think this may be useful to know:
Several other EVO forums ("fora?") have reported great success with this low-profile charger. I just got it off of amazon myself...

You can also get 1-meter cables from Blackberry themselves on Amazon for $2.50 each, so if you have Amazon Prime, gets you a flexible solution for 11 bucks or so. I have ordered mine and will report back in 2 days...

This is actually the same one I linked earlier minus the iPod cable and much cheaper
EDIT: Best Buy seems to have stopped carrying this product. I updated the link in my post above to Slappy_G's post

Do they make one with 2 USB ports? One for charging the phone and another for your Bluetooth head piece.

I'm not allowed to post links yet, but you can search for Scosche to find their products. They make dual port USB chargers.
Scosche makes a couple different models, one is advertised as having 2 amps over the two ports.
On a side note, I tried buying a blackberry micro usb cable off Amazon, and it starts to charge my phone for a second or two and then stops, it's very strange. I think it might work with the home charger, but I didn't check as I didn't notice till later that the charging stopped so soon.
Doing some cleanup and checking threads I promised to respond to...
The Belkin works great, and my wife has the 2-port Scosche. However, for me, NEITHER of them show "Charging(AC)" on either of our 2 Evo's. I have tried the charger in several cars, and same result. Not sure, but I'm guessing they are putting out incrementally less than 1A.
Not sure if that keeps the phone from triggering "quick charge" mode or not.
I just got 2 HTC car chargers from ebay, sent from Hong Kong. It says o/p:5.0V-2A so im not sure if I should use them.. here is what they look like.. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=170511321504&ssPageName=STRK:MEWNX:IT
Does anyone have a OEM car charger? I would like to know how many amps it puts out. The wall charger is 1A so will 2A kill it? I sure wouldent use it much only if needed.
I have a charger from iGo, works great and has swappable tips so you can use it with other phones or devices, think it was $15-20 with a free tip.

Can someone here confirm that this does deliver the full 1A? There is a review on Amazon from an EVO owner who says his phone sees this as USB and not AC charging.

If you were trying to draw three amps from a 2-amp capacity charger, you could damage the charger. However, a device that draws 1 amp from a 2-amp charger will draw one amp. Chargers don't push more amperage than is demanded: it's up to what the charging device is drawing. You and your device will be fine in having "too much" charger.
Thanks so much for the info. So this charger should work great then when I start using the sprint nav or google maps.

Just received two in the mail.
FAIL
Recognized as USB charging in my car.
plus 1 for resurrecting a dead thread
I bought an off brand one (looks about identical) in a respectable local supermarket. It claimed 1.5A.. so overspecced (and no there's nothing wrong with overspeccing, devices won't draw more power than they can handle so long as the input voltage is correct).
Like the previous poster's belkin experience, my korean SGS (shw-m110s) saw it as a usb, not ac. I took it apart and shorted the data pins together, took about 5 minutes). Then it recognized as AC and charged a little faster I think, but still at empty (the fastest time to charge normally) it charges about 1% (1.5 mAh) in 2 minutes(.033 hours).. which is just under 500mA charge rate (450 but well within the measurement error and 10% loss seems quite reasonable anyway). Anyway, sure as heck isn't able to draw 1A off of it. The wall charger which is supposedly only 700 mA charges several times faster actually! (which is probably quite safe at low charge levels, but sure seems like alot more than 700mA too me, but I didn't measure it as well).
I suspect this gizmo was never actually meant to output 1.5A (as it's not configured as a quick charger) or if it does, it only does it with large losses, and an internal voltage drop that's too excessive for the SGS to still be capable of actually pulling that much current.
Wish I knew what to buy.
I Have been using the official palm charger since June. I picked it up at sprint corporate store or radio shack. It is rated for 1 amp and come with a nice short micro usb.
If I were buying today I would go with one of the Platinum branded items Best Buys sells. I saw them for the first time last night so they must be new. So far I have purchased the Pt branded case for EVO and 2 different mounting kits. All of their stuff seems top quality. The have a 2 amp single usb and a 3 amp dual usb model that I saw.

Hi all,
I'm wondering if anyone has any experience with portable battery packs. I don't mean extended batteries either. I mean the universal usb charger kind that packs several thousand mAh.
I'm looking to get one for a nine hour flight, and I want to know what is a good brand.

I can't answer your question, but a lot of planes have a USB/charging input now. I know when I fly Air Canada, they have it.
I have had an Energizer XP18000 for about 3 months now and it has surpassed my expectations.
It holds 18000 mAh of power and will charge my Gnex and my Xoom at the same time (need to order a special tip for the Xoom/non standard device). I use it for long train rides to keep my phone topped up.
When watching HD video over 4G my battery level will drop about 1-2% every half hour, so it is not charging as fast as the wall charger, but it is enough to keep you from having a dead battery when you get to your destination. With my usage I can go 3 to 4 days and never need to look at a wall outlet.
The size is about as big as a external hard drive. There is also a wall charger that has a good size power brick in the middle of it. You can remove it when you don't need the wall charger, but I keep everything in one small bag so all I have to do is set it down next to an outlet and top up the external battery, then fold the cord into the bag and pull out what ever cord I need when I am on the move. It works just fine with the original Samsung usb charging cable.
I picked mine up from Amazon but you might be able to find a better deal if you look hard enough. They make a smaller model too that is only 8000 mAh.
I always keep it in my bag and it works so well for me that I don't even need the extended battery and leave 4G on all the time.
http://www.energizerpowerpacks.com/us/products/xp18000/
Beautiful. Thanks Dante. And yeah, I heard some planes have USB chargers now. Unfortunately I'm not flying with them. I live near YVR, but Air Canada is having a bunch of problems with their workers right now. Last thing I need is flight delays or bad service.
I did a ton of research before buying mine. I wanted a pocket sized one, that had large capacity (enough to fully charge the phone twice), and could charge a device at a full 1 amp. After much research, I bought the original version of this one:
http://www.newtrent.com/store/iphone-external-battery/iphone-battery-imp50d.html
Mine has less markings and I believe both ports on mine are 1 amp, where as the new one has one 500mA and one 1A port. Mine was also like $55, this one is on sale for barely over $40, an even better deal.
It is very powerful - 5,000 mAh will charge the phone 3+ times - much bigger than other "pocket batteries", fits in a pocket nicely (I wear cargo pants) because it's skinny, like a deck of cards. Fairly light too. Only complaint is that I bought it before MicroUSB became the new standard, so it charges with miniUSB instead.
I carry a retractable mini-usb cable, and a retractable microUSB cable, in an altoids tin, in in my pocket with it. Works great, can charge my friends phones at the same time as me. Had it for 2 years, still going strong!
There are newer designs they have now too if you look at their website.
It does take a long while to charge - 8 hours to charge fully or so if you charge off a 500mAh USB port, because it's a huge battery! a lot less maybe 4 hours if you charge off a high speed 1A charger.
i was looking at this one http://www.amazon.ca/Anker-8400mAh-...UTF8&coliid=I3IVVC4G6YETK&colid=1ILTNQ88L4FE5
it has a 2amp 5v port, this can charge a transformer prime with the screen off.
I got this one recently:
http://www.amazon.com/Anker-SlimTal..._1_2?s=wireless&ie=UTF8&qid=1335035472&sr=1-2
Its (much) smaller than my Nexus, has a built in micro-usb cable, and charges via micro-usb as well. While it doesn't have the capacity of those listed above (only 3200mAh), it was only $20 and the size really does let you take it everywhere.
It can fully charge it the phone from dead about 1.5 times.
I bought mine due mainly to the fact that it includes the micro-usb cable that hides away when not in use. It has a standard USB port as well for charging other items, but the appeal of only having to carry one item and no extra cable sold me.
My only complaint is that the built in cable could be a bit longer.
It has a flashlight too... lol
Been researching this topic lately and found that Anker's 10,000mah external battery is looking the best

I use the Veho Pebble and it's fine for my needs. I get 2 charges out of it.
after hours of my own research I also bought the Anker Slimtalk. I dont travel enough to need one that is huge and can charge my phone 8 times. This seems small enough to toss in my pocket and not bother me since its so thin and light. For $20 and the convenience of having its built in micro usb cable sounds like a perfect little invention to get me through the day.
If I traveled more I would of probably got the Energizer XP8000. Their tip program is awesome. Free tips for life but really its $2 shipping each. if you want this device to charge a whole bunch of things it can. My Acer netbook, EVO 3D, girlfriends RAZR, 3DS, bluetooth, iPad 2, Nook, and the list goes on. I've been trying to ask New Trent for almost a week if their products would be compatible with the Energizer Tip program but found that contrary to what I've read their customer support is terrible, but their prices are better than energizer. So they loose out on the sale since over the last few times of researching has allowed me to find the Slimtalk which for the price and for my needs is perfect.

Exactly why I went with it. Even while traveling I'm generally within range of a car or home charger, especially now that pretty much everyone without an iPhone has a micro USB charger somewhere.
I just wish it had a built in AC adapter as well but I'm sure the size would increase by quite a bit. Someone (iGo maybe) makes one like that but it only has about an 1100mah battery if I recall.
I found something here in the Netherlands, and I'm not quite sure if you guys in the US have the same thing..
The thing this has going for it is it's portability. It fits in your pocket, and if you don't mind a big lump in your pockets, it even fits together with your phone.
Click over there <<< to check out the dutch website of duracell. It basically is a battery with a socket plug on it, and 2 USB outlets.
Tech. info:
Output voltage: 5 volts DC
Input voltage: 5 volts DC, max. 1 amp
Capacity: 1800 mAh
Offcourse, this is the dutch version, with the dutch socket plug, but maybe there's an US version as well?
Thanks for all the info here guys. I have that crappy Black and Decker Pocket Power from a few years back, that well, isn't living up to the charge these days, so I need something else.
Still a bit too many options, but I'm sure I'll find one that works the best.
This dock looks perfect. Case compatible, data sync, mhl support and spare battery charger. Looks really solid too. Anyone have any experience with Kidigi products?

OK, I was a little skeptical up until he pulled out the little cradle to allow for docking the S3 with a case on... I love that design. That sold me right there.
Nice find. Ordered placed. Needed a new charger for my QCell anyways.Hopefully it actually fully charges my backups... lol
Just ordered one as well. Had one for my Note and really liked it. Too bad it doesn't work with my S3.
Thanks OP!

really? a dock that doesn't provide 1000mA to the phone? sad.
(also i doubt they have MHL ability.. because that does not look like an 11 pin connector. they are slightly different to reach the MHL pins.)

On the youtube video, the ac adapter is shown, and the writing says it is 1500mA. I think it only provides 500ma to the spare batt charger, if it is like other spare batt chargers I have seen. 500mA for the phone will barely keep up with general use. I would be interested to see what real world use is for charge times both in phone and spare battery.
Its a damn good dock, just ordered of amazon for £15 inc P&P which works out £5 cheaper than mobilefun and if you want next day (1-2days) its just under £20 so still cheaper. 500A is not an issue for me as i only plan to keep the phone docked (compared to leaving the phone flat not charging) so not too bothered about the charge but do like the idea of it being able to charge a spare battery.
So does that mean that the dock can output only 500 mA or that the charger that comes with it can only output that much? Can't we just use our stock charger that outputs 1000 mA with the dock or is that not how it works?

According to the specs, no matter what adapter you use (theirs is 1500mah) you only get 500.

Find out when it arrives i guess, but it realy doesnt effect me much if it takes longer to charge aslong as it charges both to 100%. I get through a whole day easily enough and ill be using this to charge overnight as I sleep so.
Mine should be getting here on Friday so I'll post a review once I put it through its paces.
I ordered a white one couple days ago too. Be here any day now. Will let u know too

Looks like mine is getting here a day early so I'll get it sometime today.
I wasn't expecting to receive mine until tomorrow, but it arrived today.
I'm unable to take any pics atm, but when I get my backup phone back from my buddy tomorrow night Ill be able too. He needed an unlocked phone for his trip to Israel so I loaned him my POS Focus.
For now I will say that my GS3 with a Gimmick Five Triobump BARELY fits, but it does fit and charges fine. The bottom curvature with the little slot removed is just slightly off from the curve of the bumper. I can slide the phone with case in and with a little pressure it sits perfectly, however if you move the dock around too much the device will be pushed up ever so slightly causing it to disconnect from the USB port. A light tap on the top of the phone and it'll sit right again.
Ill find out tonight how well it actually charges my phone since it was already at 100% when I received the dock. Now as for the battery compartment in the back, it stopped charging my QCell 2300 @90% sadly. Ill see if this trend continues after a few charge cycles. /crosses fingers
The content of my package consisted of the dock itself, a us DC adapter and 1 USB-micro cable not 2 and the dock only has 1 micro USB port so you have to choose to connect to the DC adapter or to your PC not both unless I'm really stupid and overlooked a 2nd port. I was under the impression that I would be able to have the dock plugged in with the DC charger while also running a USB from the dock to a PC or other device for syncing. Nope, Guess not...
I don't have much more to say at the moment. Gimme a couple days with it and we'll see.

I got mine today too, like you I was surprised there wasn't another usb port, but looking at the youtube video there really is only one port. My spare battery also stopped charging at around 93%, I think it may be due to the protection circuit in there. In terms of charging, I had it plugged in with usb and it charged my s3 from 40% to 100% in about 2 hours, but bearing in mind that I was also charging another battery in the second slot. I think charge times are good given that the USB max is 500mA, the thing I am wondering about is that the ac adaptor that comes with it has a output of 1500mA (even 500mA more than the samsung supplied one), I haven't tested it as both my batteries are full atm but ill let you know whether the charging via ac adaptor reduces the charge time by a third.
Interestingly enough, my phone now sits in the dock PERFECTLY with the triobump on. It sit in there nice and snug. Doesn't pop loose anymore if I jostle it around. Very nice
Just for reference, took about 50min to bring my QCell 2300 from 61% to fully charged using the DC adapter. No secondary battery chargin.Just the phone. Not a very heavy battery use day today. I was actually busy at work... lmao

Same here. Just charged my phone from 41% to 100% in about 2 hours. I can live with that. Don't have a spare battery yet so I haven't had a chance to try that out yet. And the my S3 with a Cruzerlite TPU case fits perfectly in the cradle.
I'm using the stock S3 AC adapter and usb cable btw.
just to let everyone know, charging with the supplied ac adaptor is 2.5x faster than using usb, the only issue being is that the supplied usb cable is a bit short, so ill have to buy a bigger one

By "supplied ac adapter", you mean the one that came with the Kidigi dock right? Can't you just plug the S3 usb cable into that?
Hi All! So this is my first time starting a new thread so I hope I'm doing this right. I couldn't really find a thread specifically for battery banks or battery backups so I thought I'd start one.
I was wondering what is everyone's method of backing up/recharging your battery for your cellphones? For me, the battery that comes with my phone is enough to get me through the day usually and I just charge it every night while I sleep. If I go on trips, I use the Rav Power 10000 mah battery bank. I find this a bit bulky but it works great and lasts many charges before I have to recharge again.
Everyone's taste and preferences are different so I'm seeing what other options are out there that may be lighter in weight. I'm thinking of getting their smaller one, the 5200 mah, and have this in my backpack or car for just in case.
Any mini reviews of what you have would be great :good:
Wow, cool gadgets, I need to get a bank for just-in-case emergencies. Thanks Currently i use a solar powered charger, which is really slow and somethings doesn't work as desired. Looks similar to this http://www.amazon.com/External-Univ...=8-4&keywords=solar+powered+cellphone+charger
Ive bought one at sunsky from china battery about 4000mah, but it was year before, now there is a better.
I used to have a bank that looked like a GBA SP, with foldable screens. In the screens were two solar panels, which charged the battery of, I think, about 2000mAh or something like that. The thing is now broken though. Still looking for a nice (affordable) replacement
Mine is Anker 5600
I use the Belkin 4000, size similar to a ext HDD and look nice, pocketable too

Charger considerations
Hi,
I need advise for the following:
Charger A (Li-polymer battery) output : 5V, 1A
Charger B (Li-polymer battery) output : 5V, 500mA
Device input: 5V, 750mAH (Li-ion / Li-polymer)
When using Charger A, some people comment that it will limit the current of 750mAH for the device and the device's battery should be fine since both the charger and device are at 5V. However, some people comment that this will shorten the battery life of the device since it will perform a 'quick charge' using 1A.
When using Charger B, some people comment that the device will draw more current than it can deliver and causes it to heat up and reduces the charger's life. However, some people comment that Charger B will extend the battery life of the device since it performs a 'slow charge'.
I also read that USB pins on the charger denotes if the charger is a PC or a dedicated charger. If it is a PC, the device will limit the drawing current. If it is a dedicated charger, the device will draw more current to charge itself.
I am confused as to who is right and which charger should i be using.
Can someone enlighten me ?
Thank you very much.
bought this one from Ebay, has not yet arrived, therefore I cannot tell if its good or not.
but for its price its quite a good bet, 12000mAh for 33 bucks (on sale until tomorrow)

I recommend Anker 5600 is very good for that stuff.
Hi, I use choiix power fort 10Wh http://www.coolermaster-usa.com/product.php?product_id=3001 it have 2700mAh and it's small and looks very nice. It can give one full charge for my SGSIII
I went on a trip this year and searched for a good bank, and this showed up.
http://www.sayes.co/20-powerbank.html
I tried it and it was really good, it has lots of adapters and it's cheap =P
I was able to order a RavPower 5600mAh on sale a while back ago, that was posted on slickdeals. here. I am pretty happy with the performance of the little backup, it defiantly gets the job done. My only complaint is that the body gets scratched up easily.
I was comparing the Ravpower and the Anker 5600 and they both look exactly the same except that both are branded with their logos. So I'm wondering if they're from the same manufacturer. Going to have to do some more research. However my current Ravpower power bank I do have is working great and I love this thing for trips.
I'm also thinking of getting a solar one for my 3day emergency/bug out bag. Thanks for all the suggestions.

Yeah, can someone please let me know if they are the exact same manufactuers, except for the company logos on them? I am deciding between the two. Also, what do you guys think of their 2600maH stick version? Which manufactuer would you go for over the other and why? I am very interested.
I'm using a "Scosche SolBAT II Solar Powered Backup Battery and Charger" which I bought off Amazon for something ridiculous like $15 last year.
I bought it for hiking mostly as an emergency charger. I use a Huawei phone as a GPS out in the wilderness, and the GPS app (Androzic) is quite power intensive. I have also used the same device on an iPhone and an iPod touch. The Huawei phone will receive a full charge from this battery, but the iDevices will only go to around 75%.
The solar cell on the back of the battery isn't all that efficient and will take about two days to charge the internal battery, but having it there gives you more options should an emergency occur while in the wilderness. A half hour charging in full sunlight would provide enough power for a short call or a couple of texts to family or emergency services.
The device comes with suction cups and a small carabiner, so it can be stuck to the inside of your car window or clipped to the back of your rucksack. The device is lighter and smaller than the average smartphone and can be fully charged by USB in about three hours. Interestingly, the device has a LOT of bad reviews on Amazon, so maybe they simply sent me a good one.
I also have a very cheap and nasty handcrank USB charger from dealextreme which can be used to add a bit of juice to the solar battery pack at night or in cloudy weather or can directly charge the phone in an emergency. It's a little flimsy and takes a fair bit of cranking to get enough juice for even one call, but it weighs nothing, cost about $2 and is cheap insurance out in the boonies.
My list of power equipment for the phone/GPS and the iPod Touch for a multi-day walk are as follows:
Short Micro USB cable x 1
iPod USB cable x 1
Scosche SolBAT II battery/charger with alloy carabiner
DX hand crank battery charger
Total weight is less than 200 grams

That is a nice list of equipment. How is the solar powered charger coming along?

Honestly i went with pricing. I assume if they look the same they are from the same vendors/manufactures but different brand/company. Reviews for both sound very good too. Ravpower had a promo going on a while back and i tend to see them pop up from time to time on slick deals. The stick might give you one charge but since it looks smaller than the rest, it may be the easiest and lightest to carry around. I say get a decent sized one. Anywhere between 5600mah to 10000mah so you can go through a few charges without needing to charge again.
I have a 6600 mAh(well, in my experience it's not true, more like 4-4.5k), but I rarely use it after I bought a tablet with a fullsized usb port in it.

I was looking for a solar charger. I bougth one but it crashed in two days. Therefore I returned it and now I am waiting for another one. In the place I live there are few options
Hi all, I'm considering getting this device, but want to have wireless charging.
has anyone purchased a 3rd party wireless charging receiver, and if so, what has been your experience? are you using a case?
thanks!
The Pixels do not natively support wireless charging. You will have to wait for a company to make a wireless charging case that adds this functionality.
For example, on the Pixel 1:

correct.
looking at the reviews on Amazon, many users are claiming that it works fine with the pixel 2.
I haven't used them, my only concern is how easy it would be to unplug the wireless charger in the even I need to access it either to charge or connect it to something like computer or God forbid headphones

100% agreed.
that's why I enjoy my droid turbo (built in wireless charging).
however, i MAY be fine with accepting this so long as the battery life is great as it has been claimed (able to go a full day in between charges), and I may ask for a pair of them google pixel ear buds for my birthday.
so the solution would be to get an extra wireless charging pad (less than $10) and get a pair of wireless earbuds.
but if the deal breaker for me would be the battery life. my current device as a 3900mAh battery and can go all day and then some. but, it is 2+ years old, and the battery is deteriorating, so it's not lasting as long. but if the Pixel 2 can deliver, then I may be fine with that.
Honestly battery life has been really good for me. I get 4+ hours of SoT which includes playing games and watching videos.

Oh, very cool, actually! I would also be worried about continuous unplug/replug for anyone using wired headphones or wanting to plug in for faster recharge. Let us know if you try it!
Lost wireless charging when I got the Nexux 5x. Never really missed it much. While somewhat convenient, it was slow to charge and many times when I needed a fast charge I just plugged in anyway.
So, Nexus 5X -> Pixel -> Pixel 2, same thing, I have chargers where I need them and charging is pretty quick. So, at the office, in my truck, by the recliner and in my home office I have fast chargers. I am covered. I also have a fast chargers in my backpack when I out an about.

understood that wireless charging is a preference and not a necessity.
as for me, it's more of a convenience factor as well as less wear/tear on the port (and battery life from my understanding). to have the ability to pick it up and go rather than pulling on a cord is a great help.
i did this with my wife's iPhone 7. and she really enjoys it (and it's difficult to get her to adopt to new technologies - hence why she has an iPhone).

I purchased the Spigen thin fit case and a Nillkin usb-c qi tag (short version). Have been using it for a few weeks and works with all my old Qi chargers used on my Nexus 6.
The case has a recessed area where the tag can sit without producing a bulge.
reddit.com/r/GooglePixel/comments/7an3sm/pixel_2_wireless_charging_solution_nillkin_qi_tag/
To throw my 2 cents in. Used a USB Type-C wireless receiver with my OG Pixel XL and it worked fine, as soon as received my PXL2 I connected the adapter but it was unfortunately insufficient to provide a decent charge, even over night, many times having the same or less battery percentage left than before laying it on the Qi charger. I have since tried 2 different wireless receivers with the same result. I've gotta believe they can manufacturer one that will out put enough juice to power and charge the battery. If anyone comes across one, please let the community know. TIA.
I've purchased the Nillkin short receiver and it does not work.
I charged it overnight in a thin Spigen case and it discharged 5% overnight.
I tried charging using the receiver outside of the case and at best pulled 0.31A on a 1.5A rated qi base.
What about one of the "Magsafe" type USB C cables (https://www.amazon.co.uk/COCHING-Magnetic-Charging-Lightning-Adapters/dp/B073HC1DJB/ref=sr_1_3?ie=UTF8&qid=1522506792&sr=8-3&keywords=usb+c+magnetic) if you're looking to reduce wear and tear? I assume you still get quick charge.
Looking at Nillkin's website, the tech specs on the USB-C "magic tag" give it a max output of 5V/1A. As we all know, Volts x Amps = charginess (or "Watts," for the electrical engineers). The power supply that comes with the Pixel 2 has an output of 5V/3A or 9V/2A.
So the phone's stock power supply charges at 15w or 18w. The Nillkin magic tag only feeds it 5w. At best, that's going to be a SLOOOOOOOOOW charge. The type 3 "fast charge edition" charger says it outputs more (10w). So the fast charger will send 10w to the magic tag, which will then feed 5w to your phone's battery.
Too bad. Seems like this could be a viable solution if there's a receiver that will output 10w. I mean, that still wouldn't charge as fast as the stock, wired power supply but at least it would probably charge. I'd love to have wireless charging with my new Pixel 2 but if the best it can do is 5 Watts, I'll live with the minor inconvenience of having to plug it in.
I thought wireless require all glass body which would be a no for me
