1,000 running watts: what can it power?

The WEN 56125i 1250W Inverter delivers 1,000 W continuously and up to 1,250 W for a few seconds to start motors. It handles 4 of the 14 loads on our typical list one at a time; add up the running watts of everything you run together, plus the extra starting watts of the biggest motor. As an inverter, it produces clean power suited to laptops, TVs and furnace control boards.

Runtime and fuel

The fuel tank holds 0.7 gallons of gasoline. At half load, it runs about 5 hr on a full tank. That is about 0.14 gallon per hour at half load, or 3 gallons for a full day of running, so plan your fuel storage for a multi-day outage.

51 dB(A): how loud is it?

The manufacturer rates the WEN 56125i 1250W Inverter at 51 dB(A), usually measured at 23 feet (7 m) and a light load. That is quieter than a normal conversation: suitable for campgrounds and close neighbors.

4

Can you connect it to your house?

Its panel offers 2 × 120 V household outlets (5-20R), USB ports. It has no 240 V outlet: it runs plug-in appliances through extension cords, not hardwired circuits or a 240 V well pump. It is parallel capable: linked to a second compatible unit with a parallel kit, the two outputs combine.

5

Starting, safety and warranty

It starts with a recoil (pull) cord. The manufacturer does not list a CO shutoff sensor: be strict about placement, 20 feet from the house with the exhaust pointed away. It is listed as CARB compliant, so it can be sold in California. The warranty runs 2 years (residential use).

Typical price $300–$500: good value per watt?

Relative to its running watts, the WEN 56125i 1250W Inverter scores 4.6/10 on value: a high price per watt, which its other strengths may justify. Inverters always cost more per watt than open frames: compare it with other inverters. Generator prices on Amazon move a lot, especially before hurricane season: check the current price before you buy.
