Calculate backup power requirements for HAM radio equipment, considering transmit duty cycles, temperature impacts, and equipment power needs.
CalculateStarlink Backup Power Calculator
Calculate battery backup requirements for Starlink satellite internet systems during power outages to maintain connectivity, protect equipment, and ensure uninterrupted service in remote areas.
Starlink Model
Standard models support direct DC power input with the optional DC-DC Power Supply, which can improve efficiency when running from batteries.
Starlink Standard Actuated
Power: 50-75W active, 20W idle
Starlink Standard & Enterprise
Power: 75-100W active, 20W idle
Starlink Mini
Power: 20-40W active, 15W idle
High Performance & Flat High Performance
Power: 110-150W active, 45W idle
Operating Temperature
Cold temperatures increase power usage for heating (up to +35% below -20°C), while hot temperatures increase cooling needs (up to +25% above 45°C). Extreme temperatures also reduce battery efficiency by 5%.
Usage Pattern
Active usage consumes significantly more power than idle. Choose a pattern that matches your needs during an outage.
Light Use
Basic internet browsing, email, occasional video (4 hours active)
Medium Use
Regular streaming, work from home (8 hours active)
Heavy Use
Continuous streaming, gaming, remote work (12 hours active)
Critical / Business
