  • It really works; excellent source of power in an emergency
Size: For Milwaukee 18V Battery
This is a wonderful converter. I have converters that work to convert 12v in the car to electrical. However, this one converts the power in an 18V Milwaukee battery to 110 electrical power. There are 2 3-prong outlets and 2 USB outlets on the converter and also one USB and one USB-c outlet on the part of the convert that plugs into the 18 volt battery. This works with Milwaukee and any 18V Milwaukee compatible battery. This is an amazing device. You can charge your phone or any USB-c rechargeable device and anything that plugs into a regular household outlet. This is great for outside at a work site or in any emergency where electrical power is out. It is only slightly larger than the battery you use to power it, so it is easily portable. The thing that's really important is that it really works. ... show more

  • Great for emergencies or outdoor events.
Size: For Milwaukee 18V Battery
What a great idea. I use inverters for a lot of things, but you have to have a battery or power socket nearby. I do always have an M18 battery lying around. This works very well. It's easy to snap on and power a number of things. It has USB A and C ports for charging electronics and a couple outlets. The all metal case feels solid. It works as I would expect for a 300w inverter. I can see using this camping, fishing, on a job site, in your car, etc. This would keep your phone charged during a power outage. There are a lot of reasons to use this set up and it does not take up a lot of space. Super cool. ... show more

  • Seems like a great product...just be smarter than me and read what battery type you select. haha
Size: For Milwaukee 18V Battery
Just as pictured! I have to buy a new battery for the power supply because I was dumb and misread the product. It doesn't work with the battery I have, I see now it is for the milwaukee battery...which works out anyway because I planned on getting new milwaukee sets anyway. So don't be like me and not fully read, haha. Will update when I get the right battery to see how well it works! ... show more

  • Delivers what it states
Size: For Milwaukee 18V Battery
This is a small 300 watt inverter. In my tests with a true RMS voltmeter the output read 110.9 volts and exactly 60 HZ. If you are married to the Milwaukee tools that use the 18 volt battery then this is what you need. This is great to charge tablets and phones and similar low current draw devices. You will not be running microwaves or air conditioners with this little inverter. This has a couple USB outlets for charging phones. The plug adapter mates correctly with my Milwaukee batteries. The build quality seems decent and the fit and finish is good. ... show more
