Is it ok to use the charging cable with the USB end that came with my new Samsung Galaxy Watch FE plugged into a USB wall charger or is it best to plug it into a computer?
Also, how long does it take to charge and how long does a charge last?
It all depends on the wattage. the source that provides more watts charges faster, A laptop normally provides 2.5watts through the USB, so that would be the slowest
Your watch can charge up to 5w, a normal phone charger should be at least that, as windroid said, your computer will output around 2.5w so a lot slower. Try to use your phones charger or another mains plug, not a pc
