Battery Recommendation and Heating Levels
For optimal performance, we recommend using batteries with high USB Power Delivery (measured in watts). The higher the USB Power Delivery, the greater the heating temperature. (Output Power (W) = Voltage (V) × Current (A).)
For instance:
Output Power 10W = 5V * 2A
Output Power 22.5W = 5V * 4.5A
