BELTTT2000W Pure Sine Wave Inverter, Car Power Inverter 12V to 120V AC Converter for RV, Truck, Solar, Outdoor with Dual AC and 20A Socket, 5V 2.1A USB, Surge 4000W, Hardwire Port, Remote Controller

Had this inverter for a month now and it has been performing flawlessly. It handled my lady's hair drier and my 1800w heat gun running at it's max and this inverter didn't even flinch.

This is my first Belttt inverter, a 2000/4000 watt unit. It replaced an older unit of a different brand. I have it connected to four 100Ah lithium batteries which are charged by eight 200 watt solar panels. I use it to power an older refrigerator and a chest freezer. It has performed flawlessly for several weeks now. One thing I appreciate is the quiet cooling fans which only cycle on at times of heavy output. My old inverter was terribly noisy. I would buy one again without hesitation. It was packaged well, has a very nice remote display and has good instructions for installation and use.

Using this in a 2024 Freightliner Cascadia. It's a great price for a pure sine wave inverter, but there's a few caveat's. First, if this is going to be your only AC source when the truck is turned off, then I would look for something more expensive (more efficient). This isn't very efficient, and will draw down your batteries to 12 volts or less simply by being turned on. I ran a CPAP machine which uses less than 20 watts, and my batteries went from 13 volts when I first shut down to 12 volts in the morning, causing the APU to start automatically. The pure sine wave part is nice- no more buzzing noises from my electronics, however I can't trust this unit to be on while the truck is off. Before this, I had a modified square wave Cobra, which I would not recommend- It was however, more efficient, and I could leave it on 24/7 and still wake up with 12.4 volts in my batteries.I'm keeping the Belttt inverter, but I definitely would not recommend getting this if you need to use it while the truck is off.Also the screens are way too bright at night, and there's no way to adjust them.The fans are powerful, and will activate at full speed with any kind of substantial load. You can hear them, but they aren't that annoying. On a scale of 0-5 can opener's, with 0 being the best, and 5 being the most annoying, I would rate this unit at 1 or 2 can openers max. It's tolerable. Build quality seems really good... Input voltage fluctuates rapidly when my truck is running, and output voltage fluctuates between 115 and 123 which is acceptable to me. It's more stable when the truck isn't running, but again, I wouldn't recommend leaving this unit on, even with nothing plugged in.It works for me because I have other options. I run it while I'm driving so i can charge my Anker Solix c1000 batteries

2000W inverter. Wow! Super impressed by this inverter! Inverters I have had in the past disappointed me, most put out 108-110VAC. This one steady 119-120VAC, no matter what load I put on it. Plugged in a small fridge, toaster, and hair dryer - pulling 1750 watts and steady output! I had inverter connected to a lead deep cell battery, did not want to damage the undersized battery so did not run for more than 30 secs., voltage on battery dropped to 10.8VDC but inverter kept right up with load.Now I am ready to purchase the larger Lithium battery(s) to run my set up for class B van (small microwave, rooftop AC, fridge, etc.Liked the supplied cables, the remote control panel with On/Off switch, the clear readouts. Great design, 60 Hertz and steady voltage output no matter what the load was. Very happy!

So far...so good!The inverter is working as hoped for/expected in our cargo trailer toy hauler/camper conversion.We haven't had a chance to use it that much (camper still in driveway) and I'm still figuring the little ins/outs of it.Note...at first (when I tried the microwave with it...1450 watts) it turned it on and within 4-5 seconds you could see/hear a significant drop in power. This was the normal response because it was still set to "Normal" mode by default. Once I set it to enhance mode, the microwave work correctly (full/normal look-sound). I also tried our Keurig coffee pot in enhanced mode (microwave off) and it worked correctly as well...seems to run 1300-1450 watt items fine.BTW...I'm running the inverter using a 100ah lithium Lifep04 mini battery (got on Amazon) and it's working good as well. I know that I can't run high wattage appliances with it for long periods of time without totally draining the battery but it's running the "non-high powered" items (i.e. 2 long LED lightbars in ceiling, 24" TV and 12 volt frig-via 120 adapter) fine and for long periods of time.We're happy with the performance so far and if it continues to function like it does now and for an acceptable amount of time (aka...long enough for us to feel that we got our money's worth) then I would purchase again and recommend to others.Hope the information above is/was helpful and best wishes with the product if you decide to buy!

I intended to use this with a LiFePO4 battery to run a home boiler during a power outage. The boiler would power on partially but not actually activate heating, as the control board error lights indicated reverse polarity. This may be a result of different poles being improperly bonded inside the inverter, as indicated by another reviewer. I know the problem originates with the inverter, because another less powerful inverter ran the boiler with no problems.The unit seems sturdy and has a helpful-looking display, but unfortunately with such a basic problem I cannot give it more than the minimum rating.Returned.

This is an excellent product. Installed it last month to invert my solar panel DC to AC as a backup to the power grid here in Puerto Rico. Over the last almost 3 days of a grid power outage, it has reliability kept my refrigerator running. I did not lose any food. I can definitely recommend this product. Especially like the audible warning when input power is either too low or too high.
