Works with the HART brand heated jacket.
Works with my HART brand heated jacket!!! Now I don't have to carry around the bulky HART battery. Ensure your power bank meets the required specifications.

Works great!
I'm using this on a Wulcea 12v heated jacket with an Anouv 10,000mAh mini power bank. The battery that comes with my jacket is high capacity and works really well, but is pretty heavy. I mean, it isn't heavy for its capacity, but I don't really like that I can feel it in my pocket due to its weight. My jacket has a 4mm DC jack, however, so I had to use a 4mm to 5.5mm adapter to get it to work with this USB-C to DC 12V adapter. I'm happy to report, after I plugged everything together, it works amazingly well, and now I can't feel a battery weighing down one side of my heated jacket!

Powers my M12 jacket and vest.
No issues so far. I may buy a usb-c extender as sometimes it doesn’t seat perfect in the battery bank while I’m working. But that’s prob more the battery bank than the cable

Worked for my M18 jacket
Worked well for an M18 jacket. I used a usb c inline volt meter to make sure volt draw was in spec, it was. You need a quick charge battery pack for this to work correctly.

Works as described! As long as you have the correct type of battery bank rated for the specs as described in the product information, then you should have no issues related to this adapter cable! I used it with my Milwaukee heated vest for a couple months now so far and have experienced zero issues! Definitely recommend this cable for anyone else looking to upgrade their heated gear battery’s like the big and bulky M12 Milwaukee ones! Especially trades people like myself being a mechanic, working outside on the ground at times and rolling over onto the M12 battery pack that’s placed directly over your kidneys lol.. no more feeling that now with the higher amp hour very slim battery pack I now use in my M12 heated vest! Thanks to this sweet little, handy adapter cable!

Works great with my new HEXION model M12 vest. Even though the vest has the double plug, the 2nd plug is for app control with the special m12 battery pack. My Powerbank is PD (power delivery) and works great. I do have to "wake up" the battery bank with its button before the vest will turn on, that is a powerbank issue, not cable issue.

Works great with my Milwaukee M12 heated jacket! As long as you use the proper power bank they tell you to…
