Question: Is this made by Milwaukee Tool or is it a knock off?
Document: I purchased this item to charge the two Milwaukee 48-11-1828 M18 XC Red Lithium 18-Volt Lithium-ion Cordless Tool Batteries I recently purchased to power my new Milwaukee 2650-20 M18 18-Volt Impact Driver and my new Milwaukee M18 18-Volt Lithium-Ion 6-1/2 in. Cordless Circular Saw. It feels like a well built product and does the job well. I've been using it for more than a month and didn't have any issues with it.
I am glad to see more versatility in a battery charger. As the owner of both m12 and m18 tools this product totally made sense. I highly recommend it as it beats carrying both chargers around a job site hands down. Charges the small m12 battery very fast  in well under 30 min and the large m18 in about 40 from dead. Good product exactly what I expected from Milwaukee.
bought it then found whole tool set a pawn shop bought it now have 2 chargersit works well and i do use it
I am a slightly handy granny. This little tool is easy and simple to use with the hackzall that I purchased. I am using it to cut/prune small trees and some shrubs. It is lightweight and easy to use. I like it. I am amazed at how quickly it recharges. Super.
I purchased this charger cause I wanted something I could take with me if I were traveling somewhere. While charging both M12 & M18 batteries. I grew tired of removing both of my M12 and M18 chargers from the hutch on top my tool box. This charger  is fantastic. I have already used it 50+ times. I highly recommend buying it on amazon for the best deal!
works as advertised. Picked up the Milwaukee impact 750ftlb and what a great set. Can charge multiple batteries if different types.
This Milwaukee charger is capable of charging both the 12 volt and the 18 volt battery packs. It charges fast.I recommend this charger.
It was a gift for my son. He was so happy to recieve it. It was just the make he wanted. He specificly wanted the Milwaukee Multi Voltage Charger becauseof its quality and reliability.
I have a complete line of Milwaukee tools that require this charger. I was shocked at the low cost of a replacment. Outstanding bargin. Thanks
i have many chargers on my bench today of course having cordless tools charger are a must, although this one has options to charge other Milwaukee batts, and for the price can't go wrong...
