Starlink Off-Grid Battery Runtime Calculator
Stop guessing at watt-hours. Pick your dish, your power station, and how hard you're using it — get the real-world runtime, plus how much solar offsets it for net-zero camping.
Estimates assume 90% battery + inverter efficiency. Cold weather below −10°C can reduce usable capacity by 20-30%.
The numbers behind it
Starlink Mini draws 22 W at idle, ~30 W typical streaming, ~40 W under sustained heavy load (video calls + 4K stream). It accepts native 12V DC, which skips the inverter and gives you 10–15% more runtime per Wh.
Starlink Standard (v4) draws 55 W idle, ~75 W typical, ~110 W heavy. It needs AC input — so factor an ~85% efficiency loss going through the inverter on most portable stations.
Solar sizing for indefinite uptime
A single 100 W panel delivers ~60-75 Wh per hour in clear NL summer sun and roughly 6 productive hours per day — net ~360 Wh harvested daily. That covers a Mini at typical duty (720 Wh/day) about half over, so two 100 W panels (or one 200 W) gets you net-zero from June through August.
Shoulder seasons (April-May, September-October) you'll want 300 W of panel for a Mini and 500 W+ for a Standard. Winter without a generator is unrealistic on solar alone in NL.
Rent the rig before you commit
Our Boondocker Power Pack — power station + 100 W solar — is $40/day on top of a Mini rental. Run it on your actual trip, then buy the exact size that matched your draw. It's the cheapest way to avoid a $900 mistake.
Not sure which kit fits your trip? Rent a Starlink Mini in Newfoundland for $45/day before you commit to hardware. Cancel free up to 48h before pickup.
