### ⭐⭐⭐⭐⭐ Works as Advertised
*by K***L on March 29, 2019*

I bought this inverter for use when power is out at my ski condo. I have a transfer switch for a generator input but I didn't want to store gas and have to worry about stabilizing gas and cleaning carburetors and such. So I got a 1KW inverter from an auto store and made a cheater cable to connect the single-phase inverter output to the split-phase generator input socket. It worked, but it couldn't run the fractional horsepower motor in the central heating system. The furnace (a modern high eff. double conversion gas furnace) would come on and burn but when it heated to the point that the whole-house fractional horsepower blower started, the small inverter would overload and cut off. Then cycle all over again and again.Reading the specs carefully, the 2X wattage "peak power" that *every* inverter claims is only good for a millisecond or two. While a motor takes many seconds to rev up so -- no dice. So I bought this WZRELB Reliable 4000W Solar Power Inverter 12VDC to 120V for it's 4KW continuous power rating. It comes with two set of (#5 gauge or so) power leads which I hooked up to heavy duty batter clamps. I hook this on my car battery run a 50 foot #12 to the generator cheater and start the car. The car *has* to be running or the inverter will suck the life out of a battery. In fact, at these power levels, the input to the inverter will dip below cutoff if the car's charging system is not supporting the battery.The inverter and AC wiring can handle the surges but the car's alternator and battery cannot sustain that forever. But car batteries being what they are: there to start the car for a few seconds, they can start a large AC motor for a few seconds, too. As long as the inverter and AC wiring can handle it. This one does.I've used this on top of my car's air filter in a snow storm and it starts my furnace fan just fine,, many lights, too -- LEDs with dimmers and they all worked. The surge capacity can handle anything Iv'e thrown at it. Just can't leave more than about 1.5KW sustained or I'll exceed the 130 amp alternator and start draining my battery.

### ⭐⭐⭐⭐⭐ Highly recommended
*by P***R on July 20, 2017*

I connected this inverter to 4 group 29 marine batteries in my trailer. I have 5000 and 13500 BTU AC units. It powered the 13500 BTU unit on a 100 degree day for 1.5 hours before the batteries got low. Started my generator which is only connected to a 100 amp battery charger. The AC unit then continued on the inverter just fine. It powered the 5000 BTU unit all night with no generator and I made coffee with my Keurig coffee pot in the morning. Still had 12 volts on my batteries. Worked great.

### ⭐ This is the second reliable inverter to fail in less than 1 year
*by T***N on July 27, 2025*

Voltage drops to unsafe levels when load is applied, as a hobbyists works as long as it has low amp requirements. Acting like it's 200w when it's time for power. Start up dc current draw 2/0 wire 2ft long .40amp dc and cannot provide 7.5ac output 120v...ac output at94vac.
