I have a powerbank with a 20,000 mAh capacity, from which I can power different devices.
The devices include an LED strip and a Raspberry Pi Zero W (RPI Zero W).
The LED strip consists of 60*5 LEDS = 300 LEDS, and will roughly draw 4.5 A with 50% PWM.
The Raspberry Pi requires about 170 mA.
The powerbank has 3 output ports, one capable of drawing 2 A, and the other two capable of drawing 1 A.
Would it be possible to somehow extend the current draw from these USB ports? I could put them in series, such that I would have one port with 4 A, but how would that affect voltage? I need to power both my Raspberry Pi, and the LED strip.
Would the USB port be able to handle such a high current draw?
