Hello, my question is if I can use this https://www.xiaomitoday.com/xiaomi-mi-powerbank-2c-20-000mah-review-almost-lower-price-tag/
powerbank with Arduino MEGA 2560 R3? And how do I calculate if this powerbank can handle 2.5 A current? Has anyone experience to help me?
The article you (almost) linked to says:
"Generally, there are three jacks – micro USB input port supporting 5V2A / 9V2A fast charge, and two USB-A output ports supporting 5.1V2.4A / 9V2A / 12V1.5A fast charge."
