Lightest thinnest backup power of all
from New York City
I have a Droid Razr Maxx which these days, on a full overnight charge unplugged at 7 am, runs out of battery about 7pm (if I can't charge it during the day). For those days I forget to charge it half way through the day, or if I'm out all day, this little credit card power source is a life saver if I really need to access something on my phone at say, 9pm.The caveat is this, if you plug this into the Droid Razr Maxx BEFORE the battery runs out and the phone shuts off, you can get about 2 more hours of life. If you wait until the phone is dead and then plug it into this credit card energy source, the energy it takes to start it up from dead will then leave you with only about 20 minutes of life on the phone before it drains the card and dies again.

Great for emergencies
If you forget to pack your car charger this is a great emergency back up!

I would buy this again
too short cord, love the size, ease of use
By Dan L
from Walpole, MA
I carry it around every time I go out and if my phone battery is low I plug it in and instantly get another few hours of use from it.

Not so easy for iphones
from South Texas
I bought this item with great expectations. When I received it I realized that the cable integrated in the charger was not for iphones. There is an additional adapter for iphones but then, where are we supposed to carry this additional cable? in a pocket??

HANDY LITTLE GADGET
Great for a quick jolt to extend your talking when u are not able to get a full charge. The extra %25 percent is a convenient little punch.
