A router draws about ten watts. Our radio draws about the same. This little box runs both of them for the better part of a day, and it costs a fraction of the bigger units.

If all you want is for the internet to survive the kind of outage that ends before dinner, start here. It is the shoebox-sized battery we keep telling people is usually all it takes.

Estimated from 292 Wh at 85% inverter efficiency. Real runtime varies with temperature, battery age, and how hard the inverter is working—treat these as the shape of the thing, not a guarantee. Loads above 240 W are left off because this unit's inverter is rated for 300 W continuous, and we would rather not quote you a runtime it cannot hold.

Good for

  • Keeping the radio and router alive through a short outage
  • Anyone testing the waters before buying something larger
  • Taking with you — it is light enough to carry one-handed

Not the right fit if…

  • Running a fridge, a well pump, or anything with a motor
  • Multi-day outages — the 40 W panel recharges slowly
