What is the difference in PowerCore Speed 20000 [Upgraded] and PowerCore II 20000?
One is upgrade, the other isn't! lol
I'll tell you when I get mine, but I think main difference, is the upgraded is Q3 rated. Meaning g faster charge for phones (equipment that's Qualcomm 3 quick charge ready). Plus it's backward tech to Q1/2.
Powercore II 20000 upgraded has power IQ 2.0 which has 18w output, but it also has 12w output aswell. The button is a round wheel with 8 led lights on it so to better tell you its state of charge.
