Anyone saw this yet? It is pretty expensive though, lol:
http://www.amzer.com/Amzer-3500-mAh-Battery-Backup-Solar-Charger-P83981.htm
I saw this on Fommy.com and was thinking about getting it.
How exactly does it work?
Does it charge it's own battery if not plugged in to the phone, then later when there is no sun you can charge your phone of the charged battery?
If so, that is kinda bad ass.
Yeah I think that is how it does work. If not, than that price is not worth it, lmao. Hopefully it works as how you described it though.

That is exactly how it works. It has a 3500 mAh battery battery built in. For comparison the Vibrant comes stock with a 1500 mAh battery.
That's actually not a bad price, considering that a 2500 mAh Innocell from Seidio will cost you about the same. The Innocell is an internal battery with a replacement back cover. I was going to get one but I'll probably get the Amzer now.
For comparison shopping you can go to ThinkGeek dot com and search for "solar charger" to find the 4 or so they sell. They even have a $200 for laptops.
Follow instructions for usage. Do not overheat or overexpose the Amzer Solar Charger to direct or indirect sunlight and AC/ USB charge.

WTH? Do not expose to direct sunlight? How is it a solar charger then? Idiotic legal disclaimers. This one's right up there with "Do not insert screwdriver into eye."
Nice. So basically it is worth it?
I say it depends. If I need more batteries I'd rather get them separately and have a charger specifically for it like the ones you can find on ebay.
Taking out the old battery and popping in the new one only takes a minute while charging from a solar battery could take who knows how long.

direct sunlight means lots of heat (over 100F on a good summer day), lots of heat is not good for batteries. solar charger does not mean it charges from sun.......it needs any light source.

mini semi scientific answer: they use heat to turn into electricity, and it's not that efficient, but it's enough to work (and gets better every year).
So sure, any light source might work, but something other than the sun will basically not work that well. Having it in a lighted room will do zero for it, for example.

yeah, but there is a battery in side as well. if it was just a solar charger then yes, more sun = better
I saw a similar product on Dealextreme for much cheaper. From the feedback the important thing is to find out if the charging current is at least 700mA. If not the Vibrant might not be charged properly.

A solar cell does NOT use heat to produce electricity, it uses light waves. Full spectrum light is the most efficient but any light source will work.
The waves impact the cell and cause a potential difference on the diode, this then creates a current in the cell. Heat is actually BAD for solar cells, the cooler they are the more current they produce. This is one of the reasons that solar panels in snowy environments can produce more electricity than cells in the south. Reflected light off the snow is another reason.

It's cheaper because you get less. 1800 MAh as compared to 3500 MAh storage.
I looked up the reviews of the Amzer solar one on amazon and it didn't look too promising.

People, the warning is not to put it in sunlight. It is to not put it in sunlight AND have it plugged into the AC/USB charger — thus providing 'double' charging.
Solar or not
<$20
You might want to look for one that includes a std usb adapter so you can use it w the oem cable for whatever phone/gadget, or get an Amzer mini-to-micro usb adaper for $5 (and get an adapter for your future phone, too).
But yeah. $70 is a little steep. I'd rather get two of these. You could get 4 for that price.
Edit: Im liking this. It says the battery can be replaced, and it doesn't say with what,exactly, but it looks AA sized to me. It has all the adapters, the port you plug your phone into is usb (yeah, you could probably scrap the cable and the adapters), and it looks like it chrges via the same port. None of these parts is entirely enticing, but the stuff in the bag, not to mention the bag, is a MacGyver use-for-everything in whatever way you need package. I think part of the appeal to me is the mystery as to whether it really is as all-purpose as I think it is. I love this kind of Asian innovation. I'm very tempted to support it. If I do, I'll report back.
OK, while I'm at it: $7, free shipping, with std usb so you can use your OEM cable.
Amzer sells a lot of overpriced stuff, this is one of many
solar chargers
Well i was looking for one and i got from dealextreme , but after 3 months, its not charging properly. Not sure why?! My brother got for me one and its good, he said he got from Chinabuye, its online store from China. Good battery life. so far so good.
Amzer is JUNK
Amzer makes JUNK. Purchased their junk before and it's not worth it even if it was free.
The owner of Amzer, basically gets Chinese manufacturers to make his junk and label it Amzer. His products are the same junk you can find on ebay for 50 cents.
This is BS.

Hey all!
I was looking for extended batteries for my Samsung Vibrant and I stumbled accross this awesome battery auction.
Now don't get TOO excited. This is just a $6 off of the final price of the battery. The battery itself is NOT out yet (will be VERY VERY soon) so he is just selling a $6 off of the price for $1. I talked with the seller and I got the specs for the battery.
Type: Lithiun-ion Polymer Battery, 3.7V
Size: 10mm thickness (1cm). Original battery is 6mm (0.6cm) thick so this is not TOO much fatter.
Capacity: 2800mah
Retail price (without coupon): $36
PRICE INCLUDES A BLACK BACK DOOR.
It is currently in production in manufacturing and should be out on the market very soon. If you're interested in the $6 coupon off the $36, click here.
Man I cannot wait. This is my only complaint with the vibrant as it stands!

I wonder if the new battery door will make the back flush by eliminating the small hump at the bottom of the phone? I love when Ebay is a source of new products. Who makes the beast?
Not sure on manufacturer yet but should be clear soon enough.

+1 on Juice Defender
Here's a screenshot of my battery life in the last 36 hours. I still have 9% remaining, so keep in mind that I can get 2+ hours.
what settings are you using to get that?
Man that app is really kinda confusing to figure out. I mean you can by tinkering, but wow.
Dang man, I installed juice defender and it EFFED my phone! It became so laggy that I couldn't really use it at all it took me a full 15 minutes just to get into the app manager to uninstall it...
Not sure what else you may have done to your phone but I have Juice Defender (Ultimate) on my Vibrant and my Wife's Slide and it works great. Since I get a lot of mail, text, and IM's I still can't go a full day but I am getting about double the battery life I had before I started using it.
Dont know if i would be comfortable with a thicker phone... an extra 5MM or so is rather thick. and i wouldnt be able to put it in my nice case that just came in the mail.
I got a car charger and USB cable for my desk at work and i just charge it as i need it. Mostly since im new to android and always playing with the damn thing is the reason i run low.
Another vote for Juice Defender/Ultimate Juice. On the weekends, my phone lasts over 30 hours with moderate use. During the week at work is somewhat of a different story. Running BT, music, and having to deal with poor service inside (phone constantly going in and out of service), I'm still able to get about 12-14 hours.
Overall a great app though.
As far as a thicker battery.....meh. Would definitely have to see the size difference first. And if it still fit in a case.
I think that battery is BS. It wouldnt fit in the phone.
Besides the weight you'll also have trouble finding a case to hold it.
I'm going the route of constructing a back-up battery using 4 AA rechargeable batteries NiMH (4x 1.2V = 5V, with 2800mAh AAs).
Got one of these with leads, on/off switch and cover. You can also get a squarish holder if you don't like the side-by-side layout.
I'll solder it to a mini USB cable, then use a mini to micro converter so that I can also charge mini USB phones. Parts ~$5 in parts.
If you want a fully assembled 4x AA one you can buy it here and here. They also have 1x AA and 2x AA versions, but I don't know how well those work.
Found this 2400mAh battery for the Vibrant here. Price is $59 and the picture doesn't look like the actual product.
I was thinking about gettin a bigger battery but then i found 2x BATTERY+dock CHARGER FOR SAMSUNG GALAXY S Vibrant # on ebay for 10$ and i thought i could just throw a spare battery in my pocket just in case my phone run out.
But..Are theses batteries as good and reliable as original one or the ones that phone store sell? Have you guys experienced any battery that sell for that low cost?
How about this one?

I was just wondering whether external batteries are generally quite reliable, and if so what the best brands are to go for? I am looking for a relatively powerful one - I am not afraid of a little bit of cost, but obviously I don't want to spend masses.
Thanks
Ive got a New Trent and its well built and reliable. The 11000mAH will last you for several days. Have a look on Amazon.
I have a "Just Mobile Pro" or something like that.
4400mAh with 1000mA output.
But the EasyAcc 5600mAh (which I don't have) does sound better and cheaper (on Amazon).

Hah! Good thing I didn't have a mouthful of soda there...
Good thing to remember with external battery packs is that during usage some of the charge goes to charging the battery while some is lost in heat. I think I read some where its normaly 30-40%. So for example a 11000mah battery will give you some where near 6600mah of charge so about 3 and half charges of the HTC One X.
I'm considering either the:
TeckNet® iEP387 7000mAh Dual-Port 2.1Amp Output Universal USB Battery Bank

The heat loss is inevitable but the capacity should be unchanged.
What the heat loss means is that you need more than 11000mAh to charge up the full 11000mAh battery due to the losses.

Yes but I'm talking about in the other direction. So once you have 11000mAh in the device and you charge a device that take 1800mAh you will actually use aprox 2520mAh in doing so. My numbers and calculations maybe a little flawed but my point is that you cant do a simple 11000 / 1800 = 6.1 charges as you need to take into account heat loss which is around 30 - 40% (so I read on one of the amazon reviews)
Either way both devices are nice and cost quite reasonable.

Ah yes of course. Did not realise you were talking about the other way round charger>>phone
Not sure how efficient but if say 10% loss, we still get around 5 times charge with a 11000mAh batt. to a One X.

Also don't forgot not to simply divide the battery pack's capacity by your phone's battery capacity to see how many times it will charge, unless you are charging it with the phone turned off.
With the phone on it is obviously using the usual amount for running the phone, whilst it is being charged. Add the current being drawn for keeping the phone running (say 250mA when awake) for the time it takes to charge (for me 2 hours) and you are looking at 500mAH. Add that to the capacity of your phone battery before dividing it by the capacity of your battery pack to figure out how many charges you'll get from it. Figures used are just for example purposes. Use a current widget if you want to know how much your phone is using.
Plus like a phone's battery, a new battery pack will take several charge cycles to reach full performance. Where as with a phone's battery which only takes about 2 weeks (charging it every day), a battery pack will take that much longer to get the full performance out of, as you wont likely be charging it more than once a week/month.
And then there's the battery indicators. These New Trent ones look sensible, but I once purchased a Proporta Turbocharger 5000mAHr unit. It had three blue LED battery status lights that were always on if charging. If you looked directly at them they'd burn your retinas out your skull. They could be seen from space. Stupidly and comically bright. They HAD to eat into some of the capacity.
Copper losses over the cable at the distances involved in your average charging cable will be negligible. If you really want to reduce it, don't use those silly skinny retracting yo-yo charging cable things that some of them come with. Use a decent quality USB to microUSB cable. The higher the guage of the cable and quality of copper, the less volt-drop there is. I keep a good few of these kicking about at home as they are well made but not too costly, and come with a nice cable tidy clasp...http://www.ebay.co.uk/itm/GENUINE-NOKIA-CA-101-CA101-USB-DATA-CABLE-LEAD-5230-/140579882085?pt=UK_MobilePhones_MobilePhoneAccesories_MobilePhoneDataCables_JN&hash=item20bb36c465

I'm going camping for a week and I won't be near a power socket. I'm looking at solar powered batteries to see if they are feasible but I don't want to spend a fortune unless I really have to. I've seen some on Amazon etc. but they seem to get very mixed reviews and in a lot of cases people complain they won't charge their iphone or whatever and I'm just thinking, with the HOX is there a minimum output I should be looking at ?
Are there any other factors I should bear in mind ?
Has anyone tried any and if so any recommendations ?
Thanks!
First off I would make sure that it can supply 1amp. However since this is dependent on sunshine, there is no way you can tell how much power it will actually give you. A better and more useful option is to buy one of those secondary battery packs. I've seen those go as high as 20,000ma which would give you over 10 full charges. They look nice and are not extremely bulky, certainly smaller than the solar charger.

First off, I do not think an USB port gives ya 1amp also. So the 1amp requirement might be overrated. Ofc it will charge much slower (or you wont in worst case scenario use the phone while "charging").
Second off, what I saw of solar packs, they have usually a li-ion battery pack supplied for those times where is not enough light and you need little more current it could give you. (Or the solar panel is just recharging the internal battery and you charge from that etc.)
Also are you sure about the bulky size of the solar charge vs extra bat? I mean, when you go external you wont care much about the + few cm of the solar charger as you wont have it in your pocket the whole time.
I wouldn't condemn a solar charger just yet.
So I would look for a solar pack with extended battery and read reviews if it doesn't suck which is an advice to about every piece of equip
Look at the solio bolt, got one and it is working as expected. I think it is the best you could get, but it is no magic, you need a full day of really good sun to charge the bolt

I wanted to get QI charger w/ my Nexus and ended up getting one that included a 10,000 mAh powerbank for basically the same price.
I thought it was going to feel pretty cheap, but to my surprise it seems like its pretty good quality. For 40 bucks for both a QI and a power bank in one it's pretty kick arse! So be forewarned the "IN STOCK" status is BS it ships from China so don't expect within a week; I think I got mine in 3 weeks.
Also the instructions are horrendous, not sure who translated it but its actually comedy. I think says something like... "Use it if it bulges, smells or smokes." (instead of dont) and has FAQ's that have no questions. Literally every line in the instructions does not make sense.
So you can use this as a normal QI charger. As a powerbank you can use QI or plug it in through the USB ports (2) which makes more sense so you dont have 30% power loss as with QI. Powerbank is same shape as phone just about twice as thick and slightly larger width and length. Finished material is smooth so if you have a hard plastic case it may easily slide off or not become centered well enough to charge. I have a case no issues charging through the case. It does also get a full charge and it does not get my phone more than warm (same as wall charger).

I'd be very interested in a test to see what the actual capacity of this is. Im always wary with a no name brand battery from China because they tend to always overstate their battery capacities. Wish there were some reviews, but I might give it a go anyway to test it out myself.
Looks interesting, but the lack of reviews make it sound dubious

Its weird how almost all of the qi power banks on amazon have no reviews. Seems like something everyone should have. Ridiculously useful. I am wondering why the one posted above is a good 25% cheaper than all the others of the same 10,000 mah capacity though.
Would absolutely love for the OP to test how many full charges of the Nexus 5 he could get from the device using USB and then Wireless charging, but that would probably take a while. Also OP, when you say that the case is smooth, is it smooth like the soft touch plastic on the back of the Nexus 5 or smooth like the shiny plastic on galaxy phones?
I'm waiting for RavPower Qi Wireless Charging Pad with a built-in 4800mAh battery coming back in stock. It seems like a great fit with my Nexus 5 as I checked a review from WPCentral.
Ordered one
Just ordered one. Will let you guys know when I get it, what it's like!

no problem but may be a few days I'm getting over a day cycle on my nexus so far. I bought it mostly for the QI charger the bank was a bonus/ I will keep a log but try and get full cycles out of it to make it easier.
As far as the smoothness it is more like the shiny plastic on the galaxy phones. My phone has a plastic case it doesn't slide to much but I could see if it got bumped it would move. I had bought a screen protector someone posted that i don't like it's kind of rubbery or tacky feel i was thinking about taking it off and putting it on the charger so it was a little more "grippy".
Give me a few days I'll put up some stats for you

Oh I know, but the ones sold under the badge of Samsung or LG are usually dead on their mah capacity ratings. Not so much for random Chinese brands I havent heard of before.

Amazons having a 50% off deal on battery packs if you buy the RAVpower qi charger. I just picked up the charger and a RAV 8400mAh pack for just over 60 bucks. I've been wanting both for a while now and this deal was just to good to pass up. I do a lot of backpacking and have been debating between a battery pack vs. a solar charger for some time now as well. The pack is actually lighter than any of the solar charges I was looking at. And for 18 bucks was a no brainer.
so here are some stats on this as a power bank not sure how much power loss over a few days is normal but after a full charge of the bank using the cable here is what I came up with:
night one charger started at 51% .49 of the full 2300 mAh nexus 5 battery = 1127 mAh
night two started at 18% .82 = 1886
night three started at 22% .78 = 1794
night four started at 28% .72 = 1656
night five started at 9% died at 32% = 529
______________________________________________________________________
TOTAL mAh= 6992

Interesting. And that is using the cable and not the Qi wireless charging? Its always said that Qi will have around a 30% loss in efficiency, which would make your numbers perfectly in line with what a 10,000 mah battery should do. Of course if you were using a cable it might just be that the low cost of the device translates to a less efficient transfer of energy. Still able to get roughly 3 full charges out of the power bank is pretty awesome.

Yea thats through the cable, I know even turned off there is power loss on rechargeable batteries but I don't know what is normal power degradation equates to in a percentage. I agree though roughly 3 full charges may not be a full 10,000 mAh bank, but at the price even if it equates to a 7000 bank its not bad. Throw in the QI (which is mainly what I bought this for anyway) and this is pretty sweet deal :laugh:
I'll do it again and see what I come up with for round 2
Does it have an auto shut off function?

it does shut off once it gets a full charge, using the cable as a powerbank. Never tried QI as a bank doesn't make sense so don't know this way.
Just ordered a Zenfone 2 to replace my old S3. Love the phone, but hate the non-removable battery. Took the leap anyway because of the price. What are your best recommendations for battery backup units in the ~6000 mAh, ~12000 mAh, and ~20000+ mAh ranges? I figure I can snag a small backup that can fit in a pocket and a larger one I can leave in my car/bag/backpack. Which ones have you guys experienced that are long lasting and charge effectively? Ones that are resilient? Anything to the gimmicky seeming solar charging backup units from the like of ZeroLemon or another producer?
Aukey has a "Quick Charge 2.0" battery pack that should quick charge the phone way faster than any other option out there. Other than that I'd just watch the usual deal forums, etc. to find well reviewed models on sale.
My assumption has always been that tiny solar panels probably take forever to replenish your battery pack, but I can't say I have any firsthand experience.

The Aukey ones work well, I have 2 of them and they quick charge just fine and will give you ~2-2.5 charges depending on your usage while charging.

They are surprisingly cheap! $30.00 on Amazon for a 10,000 mAh version. That looks like a good rec. Do you have any experience with ones in the range of 20-30k mAh?

I would ONLY buy Anker brand. a lot of usb mobile batteries dont have power output to charge a phone that is also in use, and also have a heavy degradation after multiple uses. I was in a jam and bought a second battery at a CVS when i was out of town on business once and left my Anker brand at home, and after 3 uses it no longer could charge my phone faster than i was using it (talking on the phone).

Is the lifespan of Anker brand backups well known to be good? I'm thinking I'll buy two of the same unit so I can quickly swap them out of my bag when they die.
I'm getting the Mi Power Bank...the 10000 mah version can be had for $14 usd. Only downside is you have to wait for the "flash" sale. There will be one tonight at 9 central time(US).
Why don't you guys try the Asus Zenpower. I bought it with my phone for a package deal and looks very solid! Small too.. though its heavy.

I looked at getting one....however Asus wanted to charge $14 for ground shipping....ordered the Mi Power bank earlier....and they charged $5 to ship. With stock in the US, there is no way Asus should be charging that much for ground....Express shouldn't cost that much! Also....I wanted the Mi Band lol
I ended up ordering two of the 13000 mAh and one 6400 mAh backup, all from Anker. They were all Amazon Prime so I got free fast shipping, and they offer their version of Quick Charge so it should be a solid option for me. I'll update with my experience after I've had them for a bit if anyone cares.

Oh I am sorry to hear that man. Did you check eBay? Coz i got mine with the phone. If i deduct the phone price, the zenpower was only $10 plus shipping was free coz it was with the phone anyway. Mi is equally good. I am done with massive brands such as Samsung.. we mostly end up paying for their advertising, marketing and brand name.
