One of the few with honest power output ratings and TRUE Sine wave
UPDATED April 24, 2022 -- I needed to replace my old inverter after six years of daily use. I have now been running the 24-volt model of WZRELB 800 Watt Sine Wave inverter every day for 7 months and it continues to work perfectly. It really does put out true sine wave electricity. I stress-tested it by plugging in my 500 watt full-size refrigerator – which requires 900 watts of surge power for a few seconds when the compressor first clicks on. This inverter didn't even blink and the refrigerator ran fine for a hour before I ended the test.This inverter can actually deliver its stated power rating. I have found many inverters overstate their true capability, claiming something like "1800 watt surge and continuous output of 1200 watts" when in the real world they can only deliver maybe half that. That’s why you see so many bad reviews and returns from disappointed buyers on so many different brands of inverters.THE FAN: Yes, it does make a little bit more noise than some others, but it is thermal-controlled so it only comes for a few seconds every 10 to 15 minutes while putting out a steady, continuous load of 300 watts into my computer and sound system for 4 to 6 hours per day. The inverter's cooling system works well… the metal case of never gets more than a little warm -- you can hold your finger on it indefinitely -- nothing even close to “hot”. Internal heat is what kills inverters, so the fact that this model runs far cooler than any I've used before, means there's a good chance it will run for many years without trouble. No guarantees, of course. I'll update this review from time to time.Tip: A 12-volt inverter takes 12 volts of DC battery current and pumps it up *10 times* to make 120 volts of AC household current output. This is hard work and puts a strain on the electronics. So always turn the inverter on for 10 or 20 seconds... give the innards a chance to warm up... before you plug in a high wattage device.As for the battery cables supplied with the inverter... yeah, they could be thicker (you can never have battery cables that are too thick) -- they are clearly marked as rated for "30 amps". My inverter is a 24-volt model, so 30 amps at 24 volts equates roughly to the inverter putting out 700 watt continuous household current of 120 volts AC. BUT NOTE: Most people will get a 12-volt inverter. 30 amps at 12 volts roughly equals *only* 300 watts of household 120 volt AC power. If you want to get more out of a 12-volt inverter and battery setup, you will definitely need to get thicker cables to go from the battery to the inverter.. This is why the 12 volt car battery in your car has such thick cables. Just get regular automobile battery cables marked size AWG #2 and you would be good to pull 800 watts or more with a 12 volt battery pack.Bottom Line: I have found this WZRELB 800 Watt Sine Wave Inverter does what it claims to do, seems well-designed and built solid. How long will it last in daily use? No idea. I'll update this review from time to time.

Dangerous Fire hazard
Worked okay for a few months of intermittent use. One day the alarm on the unit started screaming and shut off power even though batteries were charged. I tried resetting the power to the unit and upon restarting The unit Started sparking out of vent holes near the power output lugs. I was able to shut off the unit with my battery cutoff switch but would not have been able to power unit off on itself out of fear of the entire case being energized. Thankfully I was nearby and alert when the problem presented. I hate to think of the possibilities if I would not have been able to quickly cut the power to the unit. Do yourself a favor and buy something that won't start a fire unexpectedly.

Strong and stable 800 W inverter
Very stable little inverterPurchased about a year ago for use with sensitive electronics because it was pure sine wave, which it does flawlesslyRated 800 W, but has handled a 900 W air fryer with no issues multiple timesWorks great with a 600 W electric frying panMy meter shows a strong 120 V and 60 Hz even under a load (runs appliances more efficiently than inverters that put out 110 V)I plan on staying with this brand when I purchase a larger inverter for other projects

Good unit, it’s the main workhorse in my tiny office grid home
Good product. We use it as our main unit for our off-grid summer home.Be sure and include the efficiency calculations when planning your system. @90% that means a 4000watt unit uses 400watts per hour overnight just to keep operating even passively.I added a couple of panels and an extra battery to compensate for the 10% consumed by the unit.Wish they sold a compatible Bluetooth or WiFi monitoring dongle for it, then it would be 5 star in my mind.

Works like a champ, minor fan nit
Just received three of these 800W 24Vdc units today and ran them through their paces. They works like a champ! It has no trouble handling my computer loads, all under 300W. I also tested with a 800W space heater and it just ran with it, no issues.With no load it draws around 0.30A @ 26.5V = 8W. That is an impressive number and why I got the 800W version. With a 250W load from a linear power supply (which is pretty nasty), the inverter runs a tad over 85% efficiency which is in-line with the specs. I can't complain.The unit stays cool and is silent with around a 150W load... but every once in a while it does decide to turn its fan on and that is fairly noisy for about 10 seconds. It would have been better to simply run the fan more slowly, then it would be near silent 24x7. A minor nit, but the manufacturer really should make that change. I will probably add some external air flow to prevent that (but I shouldn't really have to, right?). Not gonna dock any stars though. I'm really happy with these units.

Good unit
This unit did a good job for as long as I tested it but I need a stronger one. It ran most everything in my house. Would not run the dryer or deep well pump.
