Review on 💡 GoWISE Power PS1003: 2000W Pure Sine Wave Inverter w/ 3 AC Outlets, 1 USB Port, Remote Switch & 2 Battery Cables - 4000W Peak (Grey) by Besim Kahsar

This 2000w inverter has been installed in my caravan for almost 3 years and it's still working. I can confirm that it is capable of delivering at least 1750 watts. My wife uses it to run her 1875w hair dryer (claimed power) for 5 minutes at a time while running other low power appliances at the same time. Although the hair dryer says 1875 watts, the maximum battery output I've seen is 1750 watts. I have no doubts that the inverter can deliver the full rated power. The inverter powers our 1500w microwave and our 1000w coffee maker, just not at the same time. To get the rated output you need a battery and cable that can handle at least 160 amps, that's a lot! In my case, that means two 100Ah lithium batteries (rated for 100 amps of continuous discharge each) and a large 2/0 wire (about 4-5 feet for the entire + and - circuit). Don't think you can hook this up to a car battery with the included cables and get rated performance. We've been using this for three years and have never overloaded it with proper wiring and a big enough battery.
