Quick Answer
Satellite phones can be used with a power bank for short-term backup power, but they typically require a dedicated power source due to high power consumption.
Choosing the Right Power Bank
When selecting a power bank for a satellite phone, consider a unit with a high capacity (mAh) rating, ideally above 20,000mAh. This will ensure you have enough power to charge your satellite phone multiple times. Look for power banks with multiple USB ports and a high power output (e.g., 5V, 2A or higher) to support the satellite phone’s power requirements.
Power Bank Capacity and Charging Times
The capacity of your power bank will determine how many times you can charge your satellite phone. For instance, if your power bank has a 20,000mAh capacity and your satellite phone requires 10Wh (e.g., 5V, 2A) to charge, you can estimate that it will take around 2,000mAh to fully charge the phone. This means your 20,000mAh power bank will provide approximately 10 full charges.
Tips for Extended Trips
When using a power bank with a satellite phone for extended trips, consider the following tips: (1) use a high-capacity power bank with multiple USB ports, (2) choose a power bank with a high power output to minimize charging times, and (3) consider a power bank with a built-in solar panel or a separate solar panel to recharge the power bank during the day. This will help ensure you have a reliable power source for your satellite phone.
