Customer Reviews for Milwaukee M12 12- volt Lithium-Ion 4-Port Sequential Battery Charger

Purchased a second station to replace the first that failed < 6mo... didn't last 1 hour. (4) batteries from the old charger placed on the new charger. Checked 1 hour later - all indicator lights off. Don't be fooled by Milwaukee replies in the reviews. the MIN fee is $44 - and the charger is $59 retail. Will stick with the single unit chargers & definitely considering replacing all 10+ m12 tools - If I can't charge my batteries, the tools are of no use to me.

This charger is great I use it after my done vacuuming with my m12 W/D because the battery’s in them are empty of power so this is a great charger to have & use.

I now am the proud owner of 3 of these that are completely useless. I have sent this product in various times for repair. PLEASE, Milwaukee STOP making this JUNK product and develop a better product! I'm a loyal Milwaukee consumer, BUT this product has me at the end of my rope!!! With minimal use, three of these have stopped working. DO NOT BUY and consider other tool options. If I can't keep my batteries charged then my tools are useless as well.

Purchased two of these over the past few years. First one failed (no lights / no charging). Ordered a new one, and it did the same thing a short time later. Not worth the money and aggravation

This charger is great I use it if my other chargers are still charging other batteries because I have mM18/12 chargers as well but I use them for my m18 batteries not as much for the m12 so this is a great backup 2 have.

I HAVE HAD MINE FOR ABOUT A YEAR NOW AND NEVER HAD A ISSUE WITH IT. ALSO MINE DONT MOVE FROM ITS SPOT. I KEEP IT IN ONE AREA IN MY TOOL BOX AND NEVER HAD A ISSUE WITH IT. IT COULD BE BETTER

I like this item but it doesnt last very long definitely needs improvement but as long as i can return it for another free of charge I’ll keep using it

Not sure why the low rating, probably only bummed out users chiming in here. I have had mine for several years with no complaints. This charger does what it is supposed to do and is very convenient. Some ideas for improvement would be: 1) make it lower profile: that rear part is a lot of unnecessary plastic. 2) make it 6 bay.

This 4 Port Is great when i use my M12 W/D vac i use it to charge those backup .

Milwaukee makes great quality tools; this charger works perfect; Highly recommend

Works very well very fast charge. I love the product.

this is is great because if your m12 battery is low this adds + 2 it & this has a 4 port that's great.

this 4 port is great i use it because my m12 w/d vac sucks power fro them quick so this charger is good 2 have 4 them .

Bought this and 2 new batteries, put old batteries on charger with new ones and charger started blinking red and green and shut down, put same batteries on single charger and all charged, this thing isn't worth any stars. Come on milwaukee I expect better for the prices you charge.

I had to return the first one because it kept flashing red and green when I had four battery packs in it and eventually all of the lights would go off. I just had to unplug the second one and wait a couple of minutes to get it to come back on again. Last night one of the battery packs was flashing with the red and green again so I pulled it, waited a minute, then reseated it. This is not typical of Milwaukee equipment, but they struck out on this one! Sadly, they are aware of these issues because numerous other people have had the same problem. Go to just about any forum and you'll see that what I've had to do is the "answer". For the nay sayers out there... All four batteries are nearly new, charge completely and correctly on any other charger, function as expected, and hold a charge as expected. Save yourself some headaches and stay away from these things until Milwaukee gets their act together and gets them right.

Great that the footprint of this is the same as two regular chargers. It charges in sequence which is fine for me since I charge overnight. Hasn’t gotten too hot either.

i bought this charger to charge multiple batteries at once. After I got it I find out that it does not charge four batteries at once but rather will charge only one at a time. Nothing in the description of this item was that mentioned. Very deceitful and dishonest to say the least. Takes its value way down and its practicality to practically zero!!

Just quit working. I need to return for exchange

Makes it easy to charge multiple batteries without having to use multiple single battery chargers and multiple electrical plugs. Excellent addition to the Milwaukee 12V group.

It seemed to work fine when I got it in mid December 2022. I put four batteries in it, they all charged fully, and the green lights came on. In mid January 2023 I went to take one of the charged batteries off and noticed that the green lights were off. I unplugged it for a few minutes as the manual says to do and the lights came back on again. I came back the next day and the lights were off again. I've performed this routine 4 times now and end up with the same result. Fortunately there is a service center 15 minutes from my house because it would be a real pain to have to send it back since I purchased it online. I've used Milwaukee tools for over 30 years without any problems until this past year. This is the 3rd defective product I've bought in 11 months.

This four bay sequential charger is exactly what I needed. This is attached to my garage wall, easily installed, and looks fantastic. I knew it was a sequential charger and for me that is all I need.

I did not fully read this and they charge separately not at the same time.

Quit working after 3 weeks, I was really excited to condense and save space. Should have real the reviews before buying
