M12 Battery Adapter and Portable Power Source for Milwaukee 12V M12 48-59-1201 Li-Ion Battery Adapter with 5V 2.1A Wall Plug, USB Output & DC 12V Outlet for 12V Heated Jacket(Adapter-ONLY)

It dose what I needed it to do added life to items the battery’s on my meters were old and don’t hold a charge this item allows me to keep them plugged in with a m12 battery and keep using them some of these meter are very expensive and cost a lot to replace this gave them new life would I highly recommend this product to others in the same field of work that need to keep items charged while working fyi I made the cord but it’s simple to find the one you need on Amazon

First thing i noticed, If its a USB C, its a 25% chance it will work on anything but a phone. I am not sure whats different about this charger/power source. I can plug in my hotspot, and it wont work, i plug same cable into ANYTHING else, and it works fine. Its a matter of figuring out which cable works with this particular power source. Same issue with micro USB, i have flashlights that work fine on any cable anywhere else, but on this.....nope. Also, to charge, dont forget to press the button on the back. Its not automatic on either. Big disappointment. I am keeping it ONLY because its not worth my time to send it back, and on a job, it has its uses.

Has regular power out for Milwaukee heated clothing and a usb out for charging your phone or anything. I use mine and the USB to power my heated vest! Will definitely buy another for camping!

I bought this to replace the 12v power source in my Milwaukee heated jacket. The DC adapter would not fully plug into the battery source and did not work for my application. If you need this for the same application I recommend going with the original equipment replacement.

Ordered despite review saying it did not fit plug for Milwaukee heated jacket. It does fit now (Oct 2023]. Looks like maybe it was retooled with a wider hole.

wish it worked

Would not work plug does not extend far enough!! Returned tried another one same problem!!!

It works great, once you realize that has an on /off button. Very convenient!!!!
