Portable USB Rechargeable 1400mAh Emergency Battery Pack

Pros: It's extremely compact and light, easy to use and it does substitute a wall socket for charging small devices. Tried it with my motorola V3i, it worked. It even powered my standalone GPS, although it heated up and made electrical noise. Won't be doing that again, don't want to ruin it because the GPS requires too much juice.
Bright led for when you need to see in the dark.

Cons: It does take a while to recharge
And that's it.

Other: Buy it if you need a portable charger.
It's really well built, sturdy and solid.
I was surprised.
I do recommend it.

Pros: - very well build for the price, feels solid and a bit like rubber to the touch
- was able to charge a device a similar branded charger had problems with
- fairly bright LED build-in
- nice display of the batteries capacity status with 5 small LEDs
- USB plug for charging the internal battery is build into the device
- USB to miniUSB and iPod cables are short and don't feel cheap

Cons: - the build-in USB plug could fit tighter to the device
- the discharging process could be started by just plugging the device to charge in and not having to hold the "power" button for 1 sec

Other: I am totally satisfied with this device and it did surpass my expectations.
I already ordered another unit that I will give to another person as a gift.

Pros: o. Press button to check battery charge. o. Shows charging and battery drain status through LEDs. o. Can be used as a flashlight which can be useful every once in a while. o. Holds a charge o. USB charging cable folds into the battery. o. Charges devices off a standard USB connector so you don't have to carry a bunch of extra cables/adapters.

Cons: none

Other: I have had this for almost a year with no problems. I charge it and leave it in my laptop bag for when my phone dies. Sometimes goes a month or more before I need it. While it won't completely recharge my Blackberry Bold, it gives me another couple of hours talk and GPS time. I highly recommend this product. It is one of the few that has completely met and even surpassed my expectations.
