Should I Buy It?

If you frequently find yourself needing power in remote locations or during power outages, and utilize power tools, then this product seems to be quite reliable and efficient. However, note that some find the unit bulky and consider the possibility of receiving a malfunctioned unit. Every effort should be made to confirm the condition of the unit upon delivery.

It’s Milwaukee! No guess work!
If you’re like me and have a boatload of M18 batteries, this is a nice have in a short power outage. Not to mention it’s intended purpose of jobsite power. It delivers the power needed for tools and at home, powering regular simple items when the lights go out, it does the job better than expected.

Good for small projects
Will run my tools, but drains the batteries quickly with continuous use.

Every household should have one…
Based on my assessment this piece of equipment should be on hand and available for whenever there is a power outage and so forth. Highly sought after item that may be needed for times when the grid is down due to post disaster. Battery powered, light weight and portable! Milwaukee and Ryobi battery powered equipment is interchangeable (adapter needed) however it’s been a great backup for us in the country whenever there’s a power outage. ... show more

Bare tool have to buy 4 milwaukee batteries to work
I didn't like that this item doesn't mention in order to work the battery operated power supply you need to buy 4 milwaukee battery's which are over 100 each and it's got to be a certain kind. There was nothing on the listing that mentioned this i have bought milwaukee tool in the past and it was says bare tool only or in pictures it shows tool only or even to have to say battery's sold separately but not it just saw battery operated power supply I mentioned this to seller and they have been nothing but rude after spending over 600 on the item I expect it to have battery's I tried to speak to seller and they just said it's all my fault for nothings looking up the model number and maybe that's partially true but when I type in battery include power supply/generator this item comes up ... show more

Good for spot needs, but not for a 5000 BTU window unit past 1/2 hour on 12 AH batteries
I expected a couple hours on the four M18-12AH batteries. Will it run a fridge, and a fan for overnight, maybe. But not an air conditioner. If you have spot stuff to run like a table saw, or a drill press, that’s what this tool is made for. Not for a power outage. Milwaulkee needs to make a 20-30 amp hour battery to make this tool more useful ... show more

Works great with most tools
It works great for many tools and charge batteries extremely fast (even if it is not its main purpose). However, some items like heat gun drown the battery faster than others. For example, I can't use the heat gun more than 30 minutes with 4x M18 12.0 batteries.
