3.4 out of 10At 1,000 W continuous it sits on the bottom rung for a power inverter, so it scores 1 on capacity.
Better on capacityLiTime 2000W InverterAt 2,000 W continuous it sits on the typical rung for a power inverter. $208.99Scores 5.0LiTime's spec table rates its efficiency at 91 percent, the 6 rung, and its no-load draw under 8 W is 8 W per kW of its 1,000 W rating, the 8 rung, so with one input short of the 8 rung it scores 7 on efficiency.
Its 2,000 W surge is 2.0 times its continuous rating, the typical rung, with no duration stated, so it scores 5 on operating range.
It has a wired LCD remote switch but no transfer switch, hardwire terminals, GFCI, search mode or parallel operation, so it scores 4 on features.
