Spare battery charger?

My favorite accessory for my samsung fascinate was the spare battery with its own dedicated charger. It could charge in the house or in the car due to its micro usb input for power. I often left this in my vehicle and just swapped batteries out there.
Ive scoured the internet and have failed to find one for the thunderbolt as they all seem to require an AC charger. Have any of you found one got the thunderbolt? Now I have 7 oem thunderbolt batteries and need a way to charge them. Especially since I'm headed to Bonnaroo....

going to bonnaroo with 7 batteries. haha thats great man but nah I have not seen anything like that. I snagged one of those el cheapo china wall battery charger with built in USB port (for charging another device) and that works great. But seriously if you have 7 batteries i dont see the need for a charger you speak of, sounds cool though.

ahahahaha that's so many damn batteries

I bought one on eBay that has the electrical plugs that fold into it and also has a plug for a USB cable.
I haven't tried the cable part though.

[Q] Car charger

I read in a couple posts that existing car chargers can't power the galaxy nexus. i've been using a cheap retractable one i bought from publix for my nexus one for almost a year, and if that one won't charge my Gnex, then i'd like to buy a new one before it comes in.
So does anyone know if theres any truth to what i read, and if so, what chargers are you guys using that works. preferably from amazon

feel bad for bumping this, but i kinda need an answer here.

I use this one. Works great. Its a 2 amp charger.

I don't know the brand of the one I use, but I think you just need to get a USB charger that has a high enough mA output. A standard USB port only puts out 500 mA, which may not be enough to charge the phone while using it. The charger that came with my phone puts out 1000 mA, or 1 Amp. So, I think you just need to look at what the amp your USB charger can provide to see if it will work with your phone. I just got a 2 amp charger with 2 USB ports from Amazon. I haven't had a chance to test it yet, but I expect it will work.

alright so basically try to get a 1000mA or 1Amp+ charger. thanks guys.

Efficient enough car charger.

Hi guys.
I have a problem finding good car charger for my phone while in car.
I either use sygic sat nav or Google maps but on top of that I stream music either via Google music or di.fm app.
Problem starts when I start streaming. My battery slowly drops down about 1% per 15min. I've tried various car chargers that have either 1amp, 2.1 amp and even dual 3.5amp they don't do the job. Only my HTC 1amp charger manages to hold the charge but it doesn't charge on top of that.
Any ideas and suggestions?

I bought the car charger from Amazon HERE earlier this year and it has worked out awesome. I usually leave it in my car but also makes a great wall charger for when you need it in a pinch and didnt bring your own. Its 17 (I got free shipping since I have Amazon Prime) and well worth it since I dont think I ever have to buy another car charger again for any device I own. Even charges my tablet.

Genuine Motorola rapid car charger, simply the best. Charges like a wall charger, seriously, phone says it's plugged into AC power
No other charger I have used, has allowed to use Google navigation and still quickly charge my galaxy nexus

In some roms like Slim ICS you can make the USB charge as fast as a wall charger!

I use a rocketfish 1a charger from bestbuy and it charges while using navigation and streaming.

I use a 1A HTC charger and never had any issues. Are you sure your cigarette lighter is working properly? It sounds like all of these chargers you've tried are charging at less than 1A.

I think 1 amp is about all it will do. It will have a hard time keeping up if you are using it a lot. I have the htc car charger and it seems to keep up for me but actually getting a decent charge while using it will be hard.

not all 1a chargers actually charge at 1a. it depends on if the two middle pins are shorted together or not.
this charger is cheap as hell - 3 bucks - and charges at a full 1a. i use it and it works perfectly.

I noticed this too, using a Kensington USB charger in the car. On my drive out to Phoenix, I noticed that having Navigation running while plugged in caused the battery to drain.
I also noticed that running Torque sucks the battery down as well. I stopped at a gas station that had a ton of gadgets, so I bought another off-brand USB adapter that stated its output is 1.5A. I also picked up the OEM extended battery at a VZW store while out there. It doesn't drain as fast now, but it does still drain a bit.

Motorola
Absolutely go for the motorola charger. I use it everytime in car, it's a 1A charger, has a nice blue light and can charge your phone even when using navigation.
And on top of that it's also cheap. I bought it in boundle with a motorola wall charger @ 10€.

is it this one guys http://www.ebay.com/itm/OEM-Motorol...846874?pt=PDA_Accessories&hash=item2a1ea6619a

Make shift cable.
If you're super cheap and/or like to DIY, I was able to get my Galaxy Nexus to recognize any USB charger as AC by cutting a USB extension cable in half. I then soldered/twisted the green and white wires within the USB cable together and then I soldered the red to red and black to black. By putting the modified USB extension in between the charger and a USB to Micro USB cable it will force the phone to recognize the charger as AC instead of USB. I sealed up my adapter with some White and Green heat-shrink tubing I had lying around so it would be easy to identify. Same thing can be done to a USB to Micro-USB cable if you want.

I hear you. This thread should have stopped at your post.
FWIW, I added your charger to my amazon wishlist.

For anyone still interested in the Motorola Rapid Charger, Amazon has it a few bucks cheaper than the ebay ad posted earlier.

Anyone in Canada interested in getting one of these for $5 + CDN shipping? I just picked up 4 of these from my mailbox in the states and am selling 3. PM me if you're game. (BTW, charges my GNex in AC mode) And if you're in Vancouver you can pick it up in person

External battery chargers

Hey guys,
Has anyone found a charger for an external battery that works well? I'm just talking about the 2100-2300 variety. Thanks guys!
Sent from my SAMSUNG-SGH-I747 using xda premium

I'm a bit confused. Would you mean external chargers, extra batteries or http://www.amazon.com/5600mAh-Exter...-66&keywords=samsung+galaxy+s3+mobile+charger such as this? Perhaps even an extended battery...

I have two.
First us the Zagg Sparq. Doubles as both a portable battery charger and a wall charger. Looks just like the old model Apple airport express wifi routers but in black. I get about 1.5 full charges from its battery but I never really go back to full, usually just a boost to about half from empty is how I use it. Has usb ports so you need to keep a cable with it but it charges anything with a usb charge interface. Got a set of 3" cables for mini, micro, and apple dock connector to keep the mess in my bag down.
Second one is a much smaller no name device with a micro usb plug sticking out one side. Got it relatively cheap. Only has enough to charge the phone back up to about 75-85%. But it is good for an end of the day boost.
A second battery would be better in most cases but these chargers are more generic so can use them on other toys too. Bought them to get an extra day or two of power when tenting.

This one charges phone or external battery or both and uses a regular micro usb for mains input so can be used in vehicle as well.

Hey guys,
My bad for not clarifying. I'm talking about the wall charger for extra external batteries
Sent from my SAMSUNG-SGH-I747 using xda premium

I just got this one its got this one for $20 off amazon its 2600mah fits nicely in your pocket so you can charge your phone while its in your pocket. A couple of problems with it is that it only came with a USB to micro USB cable but not AC adapter. It charges my phone pretty quickly but it only charged my phone about 70% before shutting off of course I was using my phone the whole time but it still should have had more of a charge in it. Also the unit its self takes forever to charge around 6 hours! But overall not a bad buy for $20.

Best wired charger for nexus 5

Hi. Can you guys please tell me which charger you are saying. And which is the best charger for nexus 5 which takes less time to charge up the battery. I recently lost my stock charger and the other chargers I have are taking much longer time to charge the phone they are like 500mAh chargers so its taking long time. Can you guys pleas suggest me the charger.

Check another post in this sub forum. It has links to the BlackBerry playbook chargers, which are awesome and cheap.

The HP 2.1 amp charger is the best charger

I second this - bought a bunch of these chargers to use everywhere.

I'd go with the blackberry folding blade chargers.
There's a review thread someone did. Lots of people here have it. http://forum.xda-developers.com/google-nexus-5/accessories/hands-best-fastest-cheapest-nexus-5-t2729066
It's also so much cheaper than the HP touchpad charger. On amazon you can get anywhere from 4 - 8 chargers for the price of 1 HP.

Just use a USB cable with a MicroUSB port at one end. You always have a computer next to you.

OP was looking for something that can charge faster than 500mA which USB charging is limited to. At that speed it can take 4+ hours to charge the phone vs 2.5 hours with stock, and 2 hours with a 2.1A unit.

My GF got an LG G2 at roughly the same time I got my phone.
I've tried charging my phone with a wide variety of chargers, including the ipad 4 charger, as well as other 2.4A heavy duty chargers from other companies. I dont know why, but NOTHING is as fast as that stock G2 charger. It beats the "heavy duty" voltage stuff by a noticeable margin.
It does a proper quick charge on her G2, and while I've read that the nexus 5 doesnt really support that quick charge, it DEFINITELY does something.
It looks like this: http://www.lg.com/us/images/cell-phone-accessories/wcp-300/gallery/medium05.jpg

I am not sure if you will get the folding blade charger in India. You can buy the CP AD2 charger. One of my friend bought it and the Nexus 5 is charging at around 1300-1400 mAh. You will get it in Amazon for 550 rupees.
