Excellent Product for Great Price

Buy this and do not buy more expensive rechargers. This one does the job quite well and does over one full charge for an iPhone 3GS in about 30 minutes. It is very small and portable. (By: Holmes D. Nesbit)

Really Good

1. Very light weight
2. Small
3. High quality feeling(not cheap materials used)
4. Shake it to see the quality how well it was made. It looks pretty strong.
For the price. It is pretty good. Those of you whose batteries won't charge anymore, you guys got the bad ones.
Mine works really perfectly. I bought two.
I did a little test
Real outlet charge time vs. this back up charge time speed
The back up charging time was a little bit slower but not bad at all
iphone 4 with outlet charger went from 13% -> 28%
iphone 4 with back up charger went from 13% -> 23%
not bad at all. just keep this in ur car
dont' buy an expensive one. why waste your money? seriously
let's save some moeny.
since last year I've spent almost 1800 dollars on amazon.
I want to share good reviews to people so that they will know what good stuff they should buy and the seller should get the money because they made pretty good products.
Im writing this review for the people and the seller who made this. (By: David)

Verry Cool

These things work great. it will charge a phone pretty much all the way up one time, great for ipods too. I even used it once for my ipad...it worked, not great but it did give me 13% extra charge when i really needed it! Small enough to put in your bag or pocket and works when you need it. (By: Erick)
