i just upgraded to the s4 from s2!
in the uk the s4 charger output is 5v 2a
is it ok to charge the s4 with the s2 charger output of 5v 0.7a??
thanks
It'll work, but not that great if you're looking for 1) to use it while charging and b) a quick charge. Also the cable makes a difference, my S4 struggles to charge using the old SII usb cable in the S4 adapter
