Here are the missing instructions: Try terminals on your battery until you get a red light. Then plug it in and wait until the light turns blue. It automatically figures out which is positive and negative for you.

I bought this charger because I got a few batteries for my Nexus S for cheap and didn't want to have to swap them out of the phone to charge them. I've actually been pretty impressed with this device. It says on the back of it that it can tell which terminals are positive and negative automatically. I was pretty skeptical of this claim until I checked it with my multimeter, and sure enough, the thing automatically figures it out when I put the battery in backwards. After I figured out that the light hints to you how to use it, I thought that the entire thing was really clever.

It also charges my batteries fairly fast, so it's probably equally clever about how to charge lithium-ion batteries. All in all, pretty happy with it.

I purchased this item for a Samsung Galaxy 2 that I was having an issue charging via the the usb port on the phone. I was faced with the option of upgrading my phone, or buying a new one for $100+. Buying a Samsung battery charger $50 (yeah ok), or going on Amazon, doing a search for options and finding this gem. This is all you need, and at $10, it is a win...hell, I even went with 1 day shipping for a grand total of $14. My only complaint is that the instructions are not the best which is easily solved by going on Youtube thanks to an awesome dude named Mitch. Here is the link: [...]

After 5 months of daily use, this charger is, in my humble opinion, the best solution to smartphone batteries that don't last through the day.
It charges my phone along with an extra battery every night. I wake up ready to take on the day with the peace of mind that I'll have my phone charged up and ready to go all day. If the battery dies, I just switch it out with the charged one and I'm ready to go. No more running around with a USB cable looking for a socket to charge my phone.

Only minor gripe is that, for some reason, it only charges the external battery to 92%. Never a full charge. I'm still giving it 5 stars though, because:
1. It's still enough to last through the day
2. Anker customer support is amazing (read below)
3. The phone is always charged to 100%

Anker customer support is also fantastic; when I complained that the charger only charges the extra battery to 92%, they immediately sent me another charger. No questions asked. Arrived 2 days later.
I offered to pay for return shipping and they refused, asking me to keep both chargers.

Anker is, in my opinion, an excellent company. Quality products that they stand behind & support.
Could not ask for more from a company.

Highly recomended!

This does charge the battery. BUT I forgot about a battery that was in the charger overnight and it destroyed it. Bulged it out so it would not fit in the phone any more. GOOD chargers DON'T do that.

FYI, a Li-ION battery that goes postal is a potential fire hazard.

I purchased this item because the USB charging port on my cell phone was damaged. So rather than pay $$$ to get my phone fixed, I bought this. Is works like a charm!! It's not hard to line up the annodes, and I really like that the indicator light turns from red-purple-blue letting you know when its fully charged. The down side was that there were absolutely no instructions. Granted, it is pretty self-explanatory, but still instructions at least detailing the indicator light would have been nice.

I use this for my Samsung/Google Nexus 4g Android phone. I can charge my phone and spare battery at the same time from a wall charger. This charger also has a micro usb port. So you can use you micro usb cable to plug into you PC or car USB port.

No instructions though, and i didn't want to plug my battery in the wrong way. I didn't see any positive negative indicators on the charger terminals. So i used a volt meter to see which one is which before i plugged in the battery. If your staring at the face of the charger with the big ANKER logo, the gold terminal on the left is positive + and the gold terminal on the right is negative - ). Look on your battery for polarity markings and plug in your battery appropriately. My battery has 3 terminals, and the middle one should be ignored for charging purposes. I'm not to sure what happens if you plug in the battery backwards????? Probably just wont charge, maybe the led on the charger lets you know somethings wrong. I don't feel testing it.

As owner of a cellphone repair shop we have many clients whos' charge ports quit working. this is an excellent option when repair is to costly or not possible. We have ordered dozens of these for our customers over the last year and have never received a single complaint, only one out of the dozens had an issue. Additionally we use two of them in our shop and they are great. We will continue to order them as long as they are 9.99 and available on amazon prime.

Using this to solve a problem with Wacom tablet USB connection issue. The Wacom Wireless Pack http://www.amazon.com/gp/product/B006MRAVFE/ref=wms_ohs_product?ie=UTF8&psc=1 doesn't include a charger, but this one works. The Wacom Intuos 5 http://www.amazon.com/gp/product/B0076HMDSC/ref=wms_ohs_product?ie=UTF8&psc=1 USB port developed connection issues after 1 year. This charger and the wireless pack allow it to be used wireless and still get charged.
