Excellent product. I managed to fully recharge my Samsung S4 mini 5-6 times. And there's no need to worry about over-charging your phone because the charger automatically stops when the phone is fully charged.
Fantsatic product. I actually didn't believe it would inflate the airbeds as quickly as it said it would. But it was fantastic. Includes all kinds of nozzle adaptors so should work with whatever airbed you own.
