Over a 2 Amp USB output, the USN3 Pro can charge two batteries with a rate of 800mA, but when connected to a more modern quick charging power supply (one that usually comes in recent phones), you'lll find a 1200mA output across the two batteries.
With intelligent charging, you won't overcharge or damage your batteries if left in too long. But this isn't the only intelligent feature on the NITECORE USN3 Pro, as it also has a small LCD screen to show the health of your batteries, time to max charge, current and voltage, along with other information.
