    • Powerful!
Size: 4000 Watts
This thing is a beast. For the price it really puts out a lot of power. Its easy to install, and works great. It does have usb ports and 12v built in if you wish to use them. Overall great product for me out on the road driving a semi. Can still overload with lots of appliance though. Its designed for 4000 watts. it will go slightly above that mark but will also warn you when you’re close to the Max wattage. Cant complain at all so far. Works perfectly for me. Would probably be amazing for some sub woofers. Maybe even over kill. ... show more

    • Appears to be everything it says it is
Size: 5000 Watts
I don’t really have a good method to test the load but I’ve loaded it up as heavy as I can and it handled it just fine. The display is easy to use and helpful. This thing is large in size, so be aware. If you are mounting it, you will need the space. Also, it requires (or so it says) a separate ground. Easy enough to do but when I was just validating it with an alligator clip, it continued without issue when I moved the unit and the ground clip came off. ... show more

    • Power inverter stopped working
Size: 4000 Watts
The worst thing I’ve ever bought, after 3 weeks it stopped connecting to phone Bluetooth, then one day when I connected the microwave it made a noise and started smoking out of the inverter, then it stopped powering the microwave, I’ve bought 2 other microwaves but it wouldn’t run it, I wouldn’t buy this again, good luck (note: the only reason why I didn’t contact the seller before was because my account was locked) ... show more
