Review on 🔋 Beleeb Pure Sine Wave Inverter: 1500W DC 12V to AC 110V 120V with LCD Display - Ideal for Home RV Trucks Boats and Emergency Power by Vincent Poolaw

By the way, the instructions that came with this inverter imply that the warranty will be void if not "installed by a professional" (specifically "the company is not responsible for any wrongdoing" whatever that means ) I have tried several inverters recently, but the results have been extremely disappointing. None of them can handle surge or spike currents, including this one! I connected two 100Ah AGM batteries in parallel (lots of current) and used the supplied alligator clips to connect. The input voltage reading is 0.2V at idle, even less under load. It didn't measure any current when it was off unless something was plugged into the USB ports (which stay hot even when it's off!). The no-load current was 0.65 A (8 W), which is above the specified characteristics. The fan didn't run below 200W and wasn't too loud when it was on. They have few error codes and they are coded so don't expect the display to tell you what's wrong when the alarm sounds. This device will alarm somewhere around 11.5V on the input and shut off the output at around 10.5V I think. It is difficult to get stable readings. If the load is reduced or removed, the alarm will reset and the output will turn on again. This can be devastating when you have a brief or real problem, as you get a slow on/off cycle that lasts until your battery dies. Again, the digital voltage readout is obviously wrong, so it's possible that the low battery cutoff doesn't know the true voltage of your battery. There is no sensor cable, so losses in the connection cable show up as lower battery voltage. There also seems to be some internal leakage as the voltage on the input loops does not match what is shown on the display. So how does it behave under load? Not very good. I used two 100w LED spotlights (switch mode power supplies) and two Weller soldering guns (resistive load on a wire transformer). 88% efficiency for one or two lights (which means 99 or 200 watts were used from the battery to deliver 87 watts or 177 watts to the load). The best performance I've tested! At higher loads I couldn't use my 50A shunt meter because even with a small resistance in the supply circuit the inverter would just shut down. With a load of 40A, the input of the inverter did not have enough voltage to work. By removing the input power monitor I was able to get 440 watts with everything connected to mains. My hair dryer test showed an efficiency of approx. 77% at 300 watts, so it depends on the level and type of load. moral of the story? Don't think you can run this on a car battery or two! But wait, there's more. I hooked up a blow dryer with adjustable speed and adjustable heat. Consumes 130/470/780W at low fan speed when plugged into a wall outlet. Connected to this inverter, it consumes 125/300/0 watts. Turns off instantly at high setting (so much for peak power) and never reaches full power at other settings. The output voltage is poorly regulated. But WORSE, the power meter on the inverter (which was correct on other loads) shows 0 watts when 125 watts are being supplied and shows 20 watts when 300 watts are being supplied (and 390 watts are being received from the batteries). I then hooked up a Milwaukee drill driver. I had to pull the variable speed trigger VERY slowly to avoid an instant shutdown. After it works, turn it on a few times and the output will turn off. Wattmeter never exceeds 400w, full speed with no load is 250w. I stopped the cartridge and gave it some power, the inverter cut out immediately and never delivered more than 20 watts. It's too smart for your own good, obviously doesn't want to play well with brushed motors. The second moral of this story: no engines. The cooling fans may work, but nothing is designed to work. It could be their advertised "soft-start technology" in action. But it doesn't really work. The display is good, but you never know if it's showing you the truth.
