You can use a portable generator to power a wide range of items, from small electronics like smartphones and laptops, to large draw appliances and power tools, and even RVs and electric vehicles.
Electricity is essential for operating lights, appliances, and important home systems, like the air conditioner and furnace, as well as charging personal devices, like a tablet or smartphone.
If you only want to power some lights, laptops, find or TV then a low power generator is enough. If your house is small and most appliances are low-powered, you just need a small portable 1 to 3 kW.
