How long will a 1000 Wh power station run a Electric blanket?
About 22 hours on the clock, allowing for the 50% duty cycle, inverter losses and a 20% reserve.
What size power station do I need for a Electric blanket overnight (8 h)?
About 122 Wh of battery and an inverter rated at least 66 W continuous with 60 W surge.
Can I run a Electric blanket on solar during an outage?
You need roughly 160 W of panels in winter to replace a day's use (240 Wh), charging through a station with a big enough MPPT input.
