Power stations in 60 seconds
Three numbers tell you almost everything
Wh
Battery size, in watt-hours
How much energy it stores. A 1,000 Wh station runs a 60 W fridge for about 14 hours.
W
Output, in watts
The most it can push out at once. A microwave needs about 1,000 W, a space heater 1,500 W.
V
Solar input voltage range
Panels must stay inside it, including on cold mornings when voltage climbs. Our checker does this math.
