4*AAA Powered Emergency Backup Battery Pack for NDS Lite

Pros: - Nice Packaging
- Small enought to fit in a pocket
- Beautiful design
- Instructions in English
- Extra energy to use when camping or traveling and energy points aren´t available.

Cons: - The batteries just keep jumping out of the case, bad industrial design.
- Almost fried my Nintendo DS =(
- Not designed to work securely with high mAH batteries (the real ones...high stamina sony)
- With one week of usage the diode fried.
- Doesn´t have a current regulator, which is very dangerous to connect to a console of at least US$ 120,00
- Plastic is a little fragile
- You need AAA, not AA batteries.

Other: For this price, it´s a nice acquisition.
Simple to use and effective.
However, be careful about rechargeable batteries which have high amperage.
You can have a bad surprise.
I think that a version with AA Batteries would sell more then the one with AAA, since the first type is more common and easy to find and buy
