I'm sure that this has probably been covered somewhere on the form but I haven't been able to find it. I cape with a smok stick v8 I tried using the supplied cable to charge it back when I first got it and I never could get it fully charged while using it if letting it charge for 6-8 hours. Finally I tried charging my phone with the cable that came with my kit and it wouldn't even send enough power to the phone to show its charging. Anyway I've been using my $5 USB cable with a 1amp Max power plug is this OK or does it really need to charge as slow as it does with smok's cable?
