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.

USB Wall Charger

Hey guys,
I was wondering if you guys knew of a good replacement for the samsung wall charger. I lost mine and I want to get a replacement wall charger that pumps out at 1A or whatever the original one was. Thanks for the help guys!

I'd stick with the Samsung original, it charges so fast! In less than two hours back to full battery, I've substituted using other chargers that comes with other phones at work and it's definitely slower

Here's the extra one I ordered, works just as good as the one that came with my phone, they seem to be identical

I like to use motorola's chargers, you can find them on amazon: "Motorola micro USB charger". They're more or less identical to the samsung ones besides the more rectangular form factor. I also recommend the motorola car charger if you're in the market for that. Both are quick charge and fill a dead battery in 1-2 hours.

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

Portable Charger

I need some imput from all you big phone users. I am wanting to purchase a portable charger and was wondering what all of you think?
Sent from my SPH-L900 using xda premium

I personally do not need a portable charger. I charge my phone for a couple of hours once in a while. But even after a full days use, I always have at least 30% battery life left.
Sent from my SPH-L900 using xda app-developers app

I do that as well. My Note one would suck up a battery much quicker than this one. I was just thinking if I were to go to a baseball game or somewhere I couldn't get a quick charge.

You might want to check the accessories section.

there are many options. It just depends on your needs. In your example, it depends on how large of external batter you would like to use. You could get something like Anker Anker Astro 3 10,000mAh. It's better than the GN2, but has over triple the battery capacity of it as well. Heck, you can charge multiple devices with it. I have one, but use it mainly for the Asus Infinity Tablet.
Another option could be something like Duracell Powerhouse or Druacell Instant charger. Of these, I used a older version of the later. It's not very big and can easily fit in your pocket. It's about the same jumbo pack of chewing gum sticks. You do need to use a USB cord, which is bad if you don't have one with you; it comes with one, but they break. On the same token, it's more universal since it doesn't matter what your phone takes since there will be a USB cord for it.
Beyond that, just use an old phone charger. Just throw it in your bag and you'll have something to charge the phone if you access to an AC outlet. I've used .5mAh chargers I got with old Jawbone earpieces and Evo 4G. They don't charge as fast, but it still charges. I do this. I have keep a charger and USB cord in my backpack for school, another in a pocket of my work uniform, another in a laptop bag, and other in my truck of my car.

^^ +1 on the anker astro 3 10000 mah portable charger. Got one from newegg for around $42 and it comes with a nice carrying case and attachments. I didn't want to buy one of those funky back door battery covers that make your phone look pregnant lol
This external charger is amazing and should make your phone last a good 72-90hrs away from a wall charge.

I have the same charger by Anker. I've owned several others as well. One of things that really impresses me about this one is that I can toss into a bag and pull out weeks later and is still showing fully charged. Zagg's would be dead after a few weeks even if I didn't use it at all. Outstanding portable charger.

A spare battery and external charger will be the smallest and most efficient way to go. You can find a deal with 2 hyperion batteries and wall charger on amazon for $20.

Note2 acts as a portable charger with a USB OTG cable

using usb otg adapter I have charged bluetooth headphones and tested the charging capability on another cell phone (my old HTC HD2).
Note2 charged HTC HD2 from 78% to 85% in 11minutes 38seconds.
Wall charger charged HTC HD2 from 78% to 85% in 9minutes 9seconds.
The Note2 charged it 79% as effectively as the 5volt wall charger.
USB OTG specifications I read say that minimum voltages provided to the other device
can range between 4.4v down to 3.6v. My testing was crude and not extensive, but it seems it was providing around 4 volts, which is more than good enough for me.
I currently use an Anker 6200mah battery inside a modded otterbox, and this charging capability gives me more reason to get the Zerolemon 9300mah battery when it comes out April 15th (on Amazon) and mod another otterbox for it.
I'm also going to make a tiny usb otg to micro usb charging cable to keep in my wallet, so I can charge all my devices off my Note2 if I have to, no matter where I am.

Thanks for justifying my purchase of the zero lemon battery. Lol

I just decided to buy a charging cable instead of make one. it was $5 from hakshop.com, see the pic. it's usb otg to micro usb and it charges and transfers files from other phones etc (mounts other phones as usb mass storage .. way cool). Hey, fits at the bottom of my wallet and charges my headphones and portable speaker and other people's phones...they say you should have jumper cables.
