Returning Product
I thought I could run a little mini fridge of this product but within 10 minutes it would kill one battery and drain the rest. I don’t like how once one battery is dead it shuts off

We use this for a mix between charging phones to our camp. Mix in my Milwaukee tools also.

Genuinely impressive
I've welded with this thing and it was better than running it on a generator. I used to use it to run my chop saw and table saw and I can handle starting both at the same time with no problem. It is genuinely impressive.

Very Limited Features
I have had the Carry-On for a few months now and overall the price point doesn’t warrant a purchase. For my setup I got 4 12 amp batteries. The biggest problem with this is if one battery goes out it stops working. It also doesn’t support pass thru charging and with no additional charging capabilities it really limits what you can do with this setup. For such a high price I would expect a lot more features, a solar charge port would be nice to go with this or really any other features. Overall I wouldn’t recommend this product.

Great step in the right direction!!
Great Product! We haven't put this through a lot of field-work yet- but what we have put it through has been pretty strenuous- an SDS Max Hammerdrill (plug-in, full speed, with load). Only improvement it'd like to suggest is making the locking handle (where you can "lock" the batteries into place?) Make it metal- anyone with a pair of pliers could walk by and cut the plastic- make it a little bit more difficult is all...or a cover/compartment like what you have on the transfer pumps?

Falls short.
Gen. 1 misses the mark. Unfortunately returned.
Milwaukee, Here is how to IMPROVE and make this what it should be!
1: Fix Standby Drain
2: Hot Swappable Batteries
3: Multiple input power sources. Example, 12/24v car socket, solar or even charging batteries via USB-C via Power Delivery protocol. While the input may not match the demand, it could act to extend operation, and when supply exceeds demand, charge the batteries.
4: not require all 4 batteries at the same time, thus allowing rotating out of lower capacity batteries.

Milwaukee, this could be so useful, and you could get the name out there in front of news stations and tv etc... with this being used by first responders in disasters, campers, well, anyone! but as it sits, this falls short.
My list is longer but this will do for now.
Feel free to contact me. In a previous life I was Chief Nitpicking officer (Meaning,
if there is a flaw to find, I WILL find it!). I'm also located in Milwaukee.

And for the love of god, make a method to charge M18 batteries via USB-C. Skill has already incorporated it directly into the battery. PD can supply 20v directly!

Powerful, convenient, and portable
This has been extremely handy for everything I've used it for. When you consider how much power it puts out its very compact. Great on the job site, around the farm, and I've used it camping as well. Milwaukee is very clear on what the designed use of this tool is for and pretty much all of the bad reviews are people trying to use it outside of its intended purpose.

Great compact tool for mobile locksmithing.
I’m a Mobile locksmith that runs several key cutting machines and this unit handles my key machines with four 5.0 batteries with ease for the day. Upgrading to the 12.0 batteries so i can do local table shows and rv camping this summer.

Yes
It does what it says it will do and does it well. I wish it didn’t require all the batteries to be installed to be usable. A lot of people are complaining that it discharges the batteries if left in place. Not true. If you disconnect just one battery, none of the others will discharge. Overall I like it.
