This is amazing.i first bought a 500amp inexpensive $40 converter. It didn’t charge my bosses co2 converter. This is like the mother of the first one I bought. I’m grateful for this converter. It charged my bosses oxygen concentrator. Which needed to be hooked up to the car battery for road trips. Also works great if the power goes out in the house. I plugged the Oxygen concentrator, Into this Electrical converter and it worked without the car being turned on. I’m so grateful for this converter. It’s literally a life safer! I can also charge my bosses portable CO2 concentrator into it while on the go. Many great uses. I suggest having it installed by a pro if hooking up to the battery. It’s powerful. ... show more

Just a word of warning to start off, even though this is a 500 W power inverter, you have to wire it directly to the battery in order to achieve that. If you use the cigarette lighter cable, it is only rated for 150 W. So be aware! Having said that, I bought the necessary size cables 5 AWG, 60 amp fuse, and wire loom to protect the wires, installed it in my work truck turned it on and worked flawlessly. All told I was in for around $100. ... show more

    • Great road trip companion
Style: 500 Watt Pattern Name: Power Inverter
I bought this for our road trip from St. Louis to Orlando. I was able to run my laptop and charge tablets. It was nice to be able to plug it into the 12 V cigarette outlet and not have to run a heavier gauge wire into the cabin of the vehicle. It does have a low voltage alarm, which will sound and shut itself off. This really only occurred when we would start the car so just make sure that it’s off prior to starting. ... show more
