Car Chargers

Hey Everyone,
Thought I would start a car charger thread.
I picked up one of these at Walmart the other day:
http://store.griffintechnology.com/smartphone/powerjolt-dual-universal-micro
And it works quite wonderfully. It's tiny, and even with bluetooth/GPS/Navigation running, it was slowly charging the battery. And it charges it quite quick if you don't have nav running.
It can be a bit annoying to pull out once stuck in, although you probably don't need to do that very often.

I have the single port version of the one you have cracking charger and sits flush worth the extra few pounds over the cheap ones and delivers plenty of juice

If you have amazon prime you can get it for less than $10 in two days here:
http://www.amazon.com/gp/product/B0042B9U8Q/ref=olp_product_details?ie=UTF8&me=&seller=
I got it the other day but haven't driven far enough yet to need to use it
Glad to hear though that it charges even while using GPS.

what is the exact output of each USB of this Griffen car charger ?
i have a JABRA charger (comes with JABRA Cruiser) and it doesnt seem to charge my GN while GPS navigation is on (even though its saying charging on the battery icon)
it used to work perfectly on my HTC Desire HD (with GPS+Bluetooth+WIFI ON )
any recommendation on how to fix this please ? like a reference output current that is enough to charge the GN while navigating ?
thanks.

The Griffen claims 1A per USB port, and I believe it.
Online reviews say some users with other phones need to mod the Griffen to charge their phone, otherwise it only supplies 100mA. Some crack open/mod the Griffen to short two terminals to get the full charging ability, and/or use a 'charging cable' which shorts the terminals within the cable.
As a reminder, the Griffen seems to charge the Note full blast, but perhaps something similar is needed for the Jabra. I suggest installing 'Currentwidget' to see what sort of charge you are getting.

SGP has one as well, it will lit up BLUE!

OR you can just get a no brand one on eBay for around $3.

Thank you for the reply.
I have battery monitor widget installed & it shows charging via usb when i connect it to jabra charger, but the weird thing is that the galaxy note starts mtp mode once i connect it!
Could it be the cable? Or shall i just take the griffin charger to solve this?
By the way,griffin charger works out of the box out do i have to solder modify it?
Cheers

I just bought this dual port 2.1A + 1A charger on eBay for £2.49 inclusive and delivered the following day....
http://www.ebay.co.uk/itm/2-1A-Dual...neChargers&hash=item19ca66b4df#ht_2865wt_1163
At first it seemed the phone was only drawing a "USB" level of current, so I was all set to rip it apart and solder the centre pins to force AC charging, but when I double checked with a dry run and a temporary short the phone switched to AC charging. Now it seems to be continuing to draw "AC" levels, so maybe I had a poor contact initially and a few (un)plugging operations have made the contacts more reliable. I'll try it out later today with satnav running and see if it keeps up with the pace and report back.
EDIT : Charge level draining like water out of a sieve with this thing whilst running satnav, and the phone said it was "AC" charging too. Switching ports didn't help.

i'm using the official car charger from my old nexus, the only charger i found can charge my phone with 3g and nav on because of the 2A output. other cheap usb chargers i tried with so called 2A output just don't work

It does 2.1a. I paid full price:-( not the current sale price. Works fine with my SGN.

Review of Anker 3.6A dual port wall charger w/pics!!!

This is a review of Anker 3.6A dual usb port wall charger: http://www.amazon.com/Anker®-18W-3-6A-Wall-Charger/dp/B00B8L36A6/
Just like cases, wall chargers market starting to get saturated with too many choices any time you search for one. But to find a good quality one that will live up to its current rating, have a reliable design that will not burn out, and with a relatively small footprint and dual output - that's not easy to find. I looked into testing of new Anker 3.6A wall charger to see how it will meet all these requirements.
First of all, the charger itself is very compact and lightweight. Under 80g with a dimensions of approximately 70mm x 55mm x 25mm it will be very comfortable to take with you while traveling. It's slim design is not obstructive if you either plug it into wall outlet (leaving enough room for another plug if its a dual outlet) or power strip where it could be used along side with other cables. For such a slim design it has a very impressive spec of 3.6A of shared output current between two ports. Obviously having a dual usb port is a huge bonus, but being able to supply 3.6A into both of them (combined and shared between two ports) or into each (if only one port used at a time) - this is very impressive! Yes, they have it labeled as one port being Android and the other one Apple, but while testing it with Galaxy Note 2 and Nexus 7 I found both ports work reliably to charge android devices. I guess this just means that you can also use it to charge Apple device with their proprietary charging circuit. I have another dual wall charger from about a year ago where I can't charger Android devices from "apple" port. This Anker charger, which I verified with their car charger as well, has no issues powering up Android devices I tested from their "apple" port. I also verified with my Note 2 that charging current was at max 2A, so the phone will be charged up at maximum speed. Furthermore, I had both Note 2 and Nexus 7 plugged in together, both charging as AC in battery setting, and I have verified Note 2 sinking 2A. Also while charging, I didn't feel any overheating, it stayed cool.
Definitely a highly recommended wall charger and a great value for under $12 for 3.6A dual port slim design which is covered by Anker's 18-month warranty.
Here are some pics:

I got this little guy ahead of your review, and can't agree more. Charger does the job very well on either port.

Thanks just ordered one. Been needing one for some time now what with three tablets and four phones. This will come in handy and with Amazon Prime's free shipping is a nice little deal.

One thing I have to mention is that when charging Note 2 and another Android non-Samsung device, I would recommend to keep Note 2 on "apple" port while other device on "android" port. I had two Nexus 7 tablets charging on both ports, starting at the same low battery level, and found the one connected to "android" port was charging at a faster rate. Bottom line, Samsung phones charge at fast rate from both ports, while other Android devices like Nexus 7 charge faster from android port versus apple one.

That explains some of the debate going on in the 2 amp car charger thread.
Some people were saying that "apple" 2.1a ports won't charge the note 2 quickly when others were saying it charged their note 2s fine. Maybe you should go report your findings in that thread too?

Review of Bolse 60W/12A 7-port usb wall charger w/lots of pics!!!

This is a review of Bolse 60W (12A) 7-port usb wall charger. http://mybolse.com/product/detail_B00L2SBZ80.html , available on amazon: http://www.amazon.com/Desktop-Technology-Bluetooth-Speakers-Detachable/dp/B00L2SBZ80/
How many smartphones and tablets do you have in your family? A lot, right? How about wireless headphones or speakers, or maybe smartwatch, or activity bracelet, and so on. What does it all mean? You have all these devices requiring a usb charging port. If you are relying on the original single port wall charger that came bundled with your gadget, you will not have enough wall power outlets to cover each device. There is a number of multi-port charging solutions, but so far I haven't found anything in compact footprint and higher than 40W. Apparently Bolse realized that if you factor in all the latest devices that benefit from 2A fast charging and latest iDevices that require 2.4A, you will need more current to keep everybody charging happily at the same time. So they come up with a 7-port compact wall charger that's able to supply 12A of a combined current!!! Here is what I found.
Arrived in environmentally friendly packaging, it had plenty of details about the product as you flip the box around. The most notable details were compact size (approximately 4.3" x 2.6" x 1.2"), 12A of a combined current, and 7 ports featuring new SmartIC technology. This new SmartIC technology is based on a controller chip which detects and optimizes amount of current based on a device you are using. Each of the 7 ports of this charger have this SmartIC technology so you don't have to guess which port to use for your phone or your tablet or even your iPad. In addition to current detection to maximize the charging speed, each port also has over-heating, over-current, and short circuit protection. As a matter of fact, the top of this charger has perforated surface to allow a better cooling of the device. The wall charger itself connects to a power outlet through a provided 5ft cable, and there is also led indicating when charger is powered up.
During my testing I had no issues connecting multiple devices to this charger, and was able to monitor and to confirm all of them charging at their max speed where the only limitation was the usb cable. You should be aware that not every usb cable will be able to provide a maximum amount of current due to a thickness of the wires which play a limiting factor in charging speed. Also, the max combined current can't exceed 12A, so for example, you can't have 7x iPad w/Retina charging simultaneous at the max speed, or 7x Galaxy phones/tablets charging at 2A each at the same time. But still, a combination of 7 USB ports and 12A of shared current is more than enough for any household.
Overall, I was very impressed with a spec of this wall charger and wasn't disappointed with its actual performance. Being able to supply 12A of combined current, providing 7-ports for charging, and equipping each port with SmartIC technology, while being covered under 12-months warranty - definitely a great deal, now offered on Amazon for $35.99.
Here are the pictures.

Great review, I was a bit cautious about buying one of these from Amazon or eBay as I have been 'stung' before by similar cheap Chinese products that fail quickly or are just plain dangerous. So now I intend to buy one based on your recommendation!
Your comment about the USB cables is interesting, I struggle to find a quality USB cable because there never seems to be a proper specification to them when ordering online. It seems to be common assumption that USB cables are all the same. Can you recommend any quality ones?

Usb cable recommendation is always a tough one because most of them are inconsistent in production quality. I used to love monoprice cables, but now you get one good out of two or three. It doesn't really matter if you spend more money since I've seen better performing $1 cables than some $6. Might as well get a bunch of cables and see which one gives you a faster charging speed. You can use something like I reviewed here: http://forum.xda-developers.com/showthread.php?t=2451375 - doesn't tell you the exact reading but rather a relative reading so you can compare to find the one with a faster charging speed.

That's been very helpful. Thanks very much for the info.

Vinsic dual usb car charger 2x 2.4A

Yesterday I received from amazon my new car charger. I chosed vinsic one because of the quality of they' re products, feedback,reviews here in xda forum and the first impact with the design, looking very different from low quality chinese products.Let me start telling that this charger is great,maybe a little heavy but it gives you a sensation of quality compared to my old one made of plastic,and the stainless steel material used gives you the feel of premium quality and a great look with the engraved logo and specs.Even the box is not cheap as other products cause you find a manual,a warranty card and thanksgiving card for chosing they re brand.The charger has 2 usb ports 2.4a each,that can charge both a nexus 5 and 4 without any problem (they could both draw from 1.2 to 1.7a on nexus 5)and spot a little green led that light up when connected to car.If you look on vinsic site they say they use an high quality chip inside to ensure a great reliability and protection that shut off power in case of overvoltage overheating and short circuit ,even the shape is made for security,you can use it to smash windshield in case of emergeny,but I wish i will never need this feature .The only little problem I found is that maybe in a car with the cigar lighter in vertical position the charger will not stay strong inside the plug, but in myne I had no problem.So what to say,this brand looks promising. Next item when I get my pay will be the 20000 mah vinsic battery in this review and I will tell you about it:
http://forum.xda-developers.com/google-nexus-5/accessories/review-t3067486

it can even be smashed into (or thrown really hard?) into your windshield to get yourself to safety if something happens?

Yes sure is heavy ,I think about 100gr, it s heavier then a nexus 4 for sure, or maybe is cause weight is concentrated in a small object. It s not a declared function,but on they re site you can see the picture I posted with a smashed glass

This is an amazing car charger to have. The Slick chrome top and black bottom gives it a unique design that not many car chargers these days have. I just plug it in the hole and it turns on for you to plug your Phone's Usb Cord Cable in. The Green light that displays when it is plugged in, is really nice and innovative. Since it is a Dual Port, it both has a 2.4a port for each to have both an even charge for your devices. So far, I have plugged in my Motorola G Phone Cord in it, and it works great. I also have plugged in one for my tablet, and that charges pretty good as well. The time it takes to charge my devices are at a good rate as well. I would say about 2-4 hours if leaving it in the place where the cigarette hole is at.
Now since I couldn't show my phone using the port, I had to use one of my tablets. As you can see from looking at it, the light turns solid green when it is plugged in. How cool is that. I will recommend this product to my family & friends.

I bought one as well, but it as not working. Actually, green led is shining but is is not charging my Note 3. I bought it on Aliexpress. I contacted the seller and he send me another one free of charge. But, the same thing. Green led is shining but it is not charging my phone. Anybody experienced same problem?

I tried again today. With very same cable it charges some Alcatel android phone, but not Note3

The Samsung micro AB cable uses 5.3 v. Not the 5V USB standard. I have a galaxy tab and can't get anything but the official charger for these services and official cable to charge at high amp. You can plug a microB USB into one side of the port and it will charge at .5 amps or so.

Choetech mini dual USB car charger – Review

Choetech is known for their wide range of smartphone accessories. Here I have the new mini dual USB car charger in for review. Not all car chargers are the same and the Choetech mini car charger is one to stand out from the crowd.
Specs:
Auto Detected Charging Port: 5V/2.4A Max
Quick Charge & Auto Detected Charging Port: 5V 2.1A/ 9V 2A/ 12V 1.5A
Dimensions:1.1 x 2.5 x 1.5 inches
Weight:20g
The packaging was nice as most companies are going for the recyclable packaging, with the cardboard box and cover sleeve. In the box was the mini dual USB car charging device and they also included a flat style 2ft USB to micro USB cable which is always a bonus when it comes to mobile accessories like battery packs and chargers. My initial impression of the products was that it was very small in fact it is smaller than my old USB car charger which had a coiled micro USB cable build in.
As for design and hardware, it has a smooth glossy black plastic body (it comes it white as well). Even though you won’t be taking this in and out of the car, it isn’t much of a fingerprint magnet which is a good thing, as I really can’t stand fingerprints! The best thing about this product is its size, as it is smaller than most of the other car chargers on the market and is lightweight and portable. This means that you can easily fit it into your pocket, and or transfer it from one car to the other on the fly with no hassle.
One of the best features of the mini charger is having dual USB ports instead of the one, this can be handy when traveling. In addition to this, when charging my phone it has a dedicated port for quick charging as only my Nexus 6 supports it. But also when it comes to charging my dad’s, sisters or moms phone, I like the fact that it has this ‘Auto Detect’ feature this means that the car charger will automatically detect the type of charge (voltage/power) that goes into your device(s) which are plugged in. This is very important because it helps to prevent overheating and overcharging that could potentially damage your device.
The USB cable which comes in the box is a flat cable which means that it doesn’t get tangled easily, saying that it is shorter than a standard 3ft cable so this helps with it being tangle free. As there is nothing more annoying than tangled cables. When you are done using it you can easily stow it away safely as it takes up very little space. Overall, you can’t go wrong with this charger. Not only is it small so it is basically hidden, it also blends into central units in most cars. If you have a smartphone and you have trouble keeping it alive throughout the day, I would definitely recommend this product.
At the time of this post it is only $15.99 on Amazon. Product Link
