Hello,

I bought an unbranded wall-wart to usb output charger from CPC, hoping
to use it to charge my mobile phone or tablet (both are Samsung). When I
connect either device using the original Samsung cable, neither device
charges.

Might help if you were more specific about the model.

Very recent ones may be more picky.

Haven't had any problems with Galaxy S3/4/5 phones.

Sony Xperia Z tablet will warn if the charge current is not enough to
charge when the device is turned on.


Cheers
