I bought their 11200mAH and their 2800mAH battery too.
Both do not live up to their ratings, even when you consider the power conversion losses.

For the Kmashi 11200mAH unit, I fully charged it overnight then put it on a battery analyzer, discharging it with an 800mA load to see what capacity it can put out (see photo).

Voltage starts out at 5.07V but drops slowly as the battery depletes.
Start - 5.07V
after 1AH delivered - 5.00V
after 2AH delivered - 4.95V
after 3AH delivered - 4.90V
after 4AH delivered - 4.89V
after 5AH delivered - 4.82V
after 5.9AH delivered - 4.70V

The unit turned off after only 5955 mAH was delivered.

If this unit has 4 qty 18650 2800mAH cells inside (11200mAH total), I would expect the mAH to be:
4 x 2800 x 3.7V = 41.44 Watt hours * 90% conversion = 37.296 Wh /5V = 7459 mAH

For their 2800mAH unit, output voltage holds up much better, but the delivered mAH at 5V is just under 1400mAH and this was with a 500mA load.

When charging both these units, charge current was limited to about 0.73A so it can take a LONG time to recharge (my charger is capable of outputting 1.25A). Even using my iPad 3rd gen charger, capable of charging at a 2.1A rate, the current draw was only 0.73A. I suspect the charging IC is just a linear lipo regulator so the charge current to the 18650 cells is 1:1 for the input current. If true, and if one goes by the advertised mAH rating of 11200, then at 0.73A charge, full charge takes 15.5 hours.

Update 16Apr2015: Now both the mini USB port (for charging the battery) and the main USB port (for connecting the phone to the battery) are so loose it constantly loses it's connection and doesn't work unless you hold it in exactly the right position. Stay away from this battery company.
As soon as I opened the package, I plugged it in to charge because I'd need it the next day. I already had my alternate usb charger plugged into the laptop so I just used that instead of the cable the battery came with. The next day, the 4 LED lights said it was fully charged. Later in my day, I found my cellphone was about to power off due to low battery. I plugged the battery into my cellphone using the usb cable the battery came with. NOTHING. I tried over and over, turned off my phone all together, pressed the power button on the battery a couple times and nothing. It wouldn't power up my phone. After getting to work, I tried plugging it in via my cellphone usb cable. It worked fine. So, the battery works fine. The cable they sent to charge it with is useless.
The night light/spot light is bright. A little too bright for a bedside night light but perfect for finding a key hole on a doorknob in the dark or walking to your car in a bad neighborhood. (bad guys see someone with a light, they tend to be less likely to bother you)
EDIT: After 2 charges, I plugged the regular usb into the wall and I tried to plug the micro USB into the side port and it pushed the plug further into the battery case. Now, I have to ensure the battery is plugged into something that won't wiggle or move at all or it'll stop charging the battery due to a lost connection to the cable.
Stay away from this battery.

Holds charge for along time and will save your life when you need it. Charge it full and keep it in your car and will come handy when you are inside where you can not charge your phone or if you want to watch a movie/play a game on your phone or tablet this will do just fine.

Amazed, I drive for a living and listen to satellite radio app and other radio stations on my phone, along with an external GPS. There were a few times the vehicle I was using had power issues. One time I was unable to start the vehicle battery was shot. I was grateful to have this External Battery Pack!!!! My phone was at 2% and had no way to charge it. Love it, love it, love it!!!!!!! I can charge my phone 3 -4 times just on one Battery Pack charge!!!!!

This is a great device to carry with you at all times in a purse, book bag, or car. You may not need it most of the time, but when you do need it, it can be a godsend.

I initially chose this battery pack over similar products because of its built in flashlight. I thought that it was an intelligent and clever addition to the battery, as it would most likely outlast actual flashlights by days (if left on continuously). I tested the flashlight outside during the night, and found that it is not quite as bright as larger handheld flashlights are, but it emits enough light to see what is in front of you fairly easily. It can also come in handy when trying to read documents in the dark, or to provide temporary light during a power outage.

This battery has a 11200 mAh rating, which is enough power to charge most cellphones four or five times over. My Galaxy S5 has a custom battery which has 7500mAh. I have tested this device with that phone, and found that the device can completely charge the phone's larger battery once with enough power to charge it about to about 50% left over. My phone has enough battery power to last at least 10 days with heavy use. For a normal cell phone, this battery pack has enough power to charge it completely multiple times. Most battery packs that are sold at stores or online have much less charge.

When the battery is being used, it automatically detects when the device it is charging is fully charged, or becomes disconnected, and stops the energy transfer. This feature can save a surprising amount of energy and make the battery life on the device last much longer.

Overall, I would recommend this battery pack to anyone who is looking for a small yet high capacity battery pack.
