Thermoelectric power generation

A portable thermoelectric power generator that provides electricity while producing heat. It's safe, quiet, highly efficient, and environmentally friendly. The external unit burns outside and emits exhaust gas, while the internal unit outputs warm air and electricity inside for safe and convenient usage. The 450g butane fuel canister can heat a 5㎡ 2-People camping tent for 8 hours. It takes only 20 minutes to heat up from 0℃（32℉） to 18℃（64.4°F), even while being used to charge 3 electronic devices (USB-A, TYPE-C, Wireless Charging) at the same time.
