This power inverter is called the TANK 3000, and let me tell you this thing is a tank. My previous power inverter was a small 140W unit. Moving to this bad boy is a huge jump. 3000W is a ton of power. There were plenty of things that my last inverter couldn't handle. I don't think I'll ever come across that issue with this 3000W unit. This will really come in handy for when I go camping, for my blow up mattress, portable shower, as well as the little things like my phone and powe bank. This unit is versatile with 3 115v ac outlets and also a few usb outlets for the smaller stuff. Its got two fans on the back to help with any over heating. This is the first inverter ive used that has a screen, which is awesome to have real time info on hand. The cables it came with are really beefy 0AWG. Although I want to mount it in my cab under the seat, and the cables it came with are definitely too short for that so I'll be getting new cables for that. Overall I'm very excited to get to put this thing to use!
