Pros: IT WILL BE YOUR FRIEND WHEN YOU ARE OUT OF YOUR HOUSE. IT CAN CHARGE ANY DEVICES THAT OTHERS CAN NOT.

Cons: THERE IS NOT DISADVANTAGE FOR THIS, EVERYTHING ARE ADVANTAGES

Other: THERE ARE CHARGERS MORE EXPENSIVES THAN THIS ONE AND THEY DOES NOT HAVE AS MANY CHARACTERISTHICS AS THIS ONE.

Pros: Small, many charging adapters, claims to be lithium ion..

Cons: Capacity is not 12000mAh. I charged a 1600mAh cell phone battery and it used two of the four indicator lights. So the real capacity might be around 5000 to 6000mAh.

Other: Hopefully the battery gets better after a few charging cycles, other than that it suits my purpose well.

Pros: is heavy. Easy to use. Many adapters. Good to take a long trip. There is a glowing indication lights.Can be used as a power adapter for the device. Build quality is high good leads and adapters.

Cons: No bags for storage together with adapters. Not clear indication of charging. Bad instruction. Without a bottle you will not understand

Other: Feel free to take it and do not think. It is useful at all anyway. Can both for yourself and as a gift.

Pros: Nice. Has a lot of connector and good quality of connector. It has a button to display de charge. It charges my cellphone, my ipad and my ipod with not additional thing required. It has 2 ports where 1 is 1 amp but it auto adapts the output amps.

Cons: Is s little bit heavy, for carry in the pocket although is not intended for that. Also as you expected is not 12000 mha i believe is in the order of 8000 it charged 3 times my cell phone my ipod and my bro cellphone and it display 2 lights. Charging takes a lot of time.

Other: I recommend buying it, specially if you travel or go camping it can charger your devices.
