RAPID Pro Power Bank 27,650mAh 300W (US package)
Milliamp-hours need a voltage basis. Use a documented watt-hour value when comparing stored energy; do not infer one from an assumed cell voltage.
Single-port output and shared power are different limits. Connecting another device may change what the first device receives.
The input port, charger, cable and state of charge can limit recharging. An output maximum is not automatically the input limit.
