It charges but sometimes it makes weird noises and the instruction manual is not really helpful so I had to figure out how it get it to start charging something on my own. The adaptors work great! And I have been able to use it for both my computer and phone. The battery life is really long.

It dose work but only for one recharge on a android phone. Be good if you needed to charge your phone to make a call in a emergency. Ill let you no if my cyber power starts to work longer... All right if you leave it on the charge until your ready to use it it will charge your android phone 2 times but still is not up to 55 hours. Ill let you no if my cyber power starts to work even longer...
