5 out of 5 eggsRock solid

Pros: It does what is says it will. I have used it to charge up my Moto X and Kindle Paper White. I have gotten several device charges on one full charge of this.

Cons: Slight con, it does get a little warm to the touch after a while. No biggie.

5 out of 5 eggsAwesome Charger

Pros: I bought the charger for $19.99 on sale.
Went with the free shipping and got it within a week.

I charged it for about 8 hours (Plugged it in before bed)
After the charge, I was able to fully charge my iPhone 5 three times and my iPod Touch 4th gen once with the charger (Over 1 week period of time).
It still had one of the LED bars lit up so I plugged my iPhone 5 in again and it charged it from 3% to 26% before running out of power.

Cons: A little bigger than I'd like, but over all not that bad.
It's about the size of a sleeve of golf balls (3 pack).

Other Thoughts: Over all I would buy a 2nd one if I needed it, but this charger lasts long enough to charge my iPhone 5, wife's iPhone 5, and the iPod Touch 4, and then still have enough power to charge my iPhone again.

4 out of 5 eggsSolid design, great life

Pros: The construction feels solid, and the connectors seem to be durable. The connectors do not wobble or have any give, and do not seem likely to snap off. The included cable is high quality and the ends appear to be encased in a hard rubber instead of plastic. The ends flex a little, which is a good thing. There are 4 LEDs on the front to indicate battery life, and the charge lasts a long time.

I kept my Motorola Photon 4G with a 1650 mAh battery charged for three days using only this battery pack. USAGE: I used a lot of wifi data, and not a lot of 3G data during this time. I did not use 4G, but I did use GPS for routing a few times. Several hours of phone calls and a couple hundred text messages.
I may have been able to stretch the amount of time it kept my phone charged to four days, but I left the phone connected to the pack overnight.

It does not seem to self discharge very fast. It's been unplugged and unused for five days, and I am checking the battery level twice a day, and it is still at four "bars" of charge.

It is very convenient that it charges via Micro USB, and comes with a cable to do so. I can charge the pack and my phone with the same included cable.

The shape and size are convenient, and it fits surprisingly well in my pocket.

Cons: The weight feels lopsided and like all of the cells are located on side. This may be true as there would need to be room for a charging circuit.

The output does not seem to be the 1.5 amps stated, and seems to be 700 mA or less. It charges about as fast as a decent car charger. No huge complaint here, but if you want your phone charged faster than you are better off finding a 1A+ wall charger. Again, no big deal.

Other Thoughts: The cable would be awesome if was just an inch or two longer, but that is a personal preference based on the location of my phone's charging port (left side, near top.)

I wish the unit would charge faster, but it is 7800 mAh, so it takes a while to charge.

With the way the weight feels off balance, I would think they could fit a little more battery capacity in it, but now I am just getting greedy...

I plan on bringing this with me on backpacking trips to replace my BioLite stove on trips lasting less than a week. It is lightweight for it's power capacity, and I may buy another one to allow for longer trips without the need for a 2lb BioLite stove for USB power.
