This thing does in fact work. Powered our tent for a four-day camping trip. With two batteries I was able to pump up a leaky queen air mattress a bunch of times, as well as keep our phones charged all the time as well. Never tried the light but I assume it works. Nice little unit. Would recommend.

This power inverter fits perfectly on our Dewalt batteries. This makes it very convenient when you need something charged when you don't have access to electricity. I like the little light on it also. I like that it has the option to charge items with a regular plug or usb or a type c.

I only got this because I have so many Milwaukee batteries. It seems really light and cheap, but the truth is that it works really well and is so simple to use. I keep it in my toolbox so it is handy and adds little weight. It even has a small light on top that puts out a good amount of illumination.
