VTOMAN FlashSpeed 1500
A 1,548 Wh LiFePO4 unit with a 1,500 W inverter (3,000 W peak), a one-hour wall recharge, and a single expansion battery that doubles capacity to 3,096 Wh. The user manual lists a switchover under 20 ms and the three AC outlets cover a refrigerator and a few small appliances at once. It is priced like the cheapest 1.5 kWh LiFePO4 units and weighs 41.4 lb, but the 1,500 W inverter is the weakest in this class: a 1,500 W space heater or a window air conditioner will trip it, and a well pump with a high start load may too. VTOMAN shows $1,399 struck through and charges $589. The maker is a newer name with a thin US service network and a two-year warranty against five on Pecron and OUPES, and no published noise figure. It is a sensible camping and CPAP backup; for whole-fridge-and-pump coverage buyers move up to a 2,000 W+ unit.
