The charger works great - once it's been charged up through your computer, bring it anywhere with you and it will charge your cell phone without a problem. Keep in mind: the charge is enough to charge up your cell phone, but not a larger device (say ipad). Also, you need to use the charger relatively soon after it's been fully charged. Otherwise it loses its charge and you'll have to recharge it a week later. Otherwise, pretty happy with it. It gives me some increased convenience, as long as I plan for it (i.e., going to be at a conference, i'll be sure to charge it right before i go into session in case i need it).
the AMP mini is a small, pocket size emergency charge and while it wont be able to fully charge your phone in might help you get home to place in on a standard charger
I purchased this for our recent trip to Disneyworld. I was able to keep my phone charged while we visited each park. My phone battery did not die all day!! Truly a lifesaver! Thank you myCharge!
After getting the myCharge, my life has gotten a lot easier. I always forget, or I'm just lazy, to charge my school ipad over night after doing homework. I wake up knowing I'm good for school and it helps get my device through the day without dying. When there isn't an outlet, my things can charge in my pocket. Thanks myCharge! :)
