Generally speaking, people living in big houses have a fuel generator, which uses diesel. But these power stations will cause air pollution. On the contrary, people can use LiFeOPO4 power stations like ITEHIL 500W.
The ITEHIL 500W LiFeOPO4 Power Station is a compact, rechargeable battery-powered generator that you can use to power your small to medium size devices and appliances on your next camping trip or outdoor adventure, backyard parties, or on-the-go power in case of an emergency. You can also use it at home in case the power goes out.
