Smarkey 12V Heated Jacket Battery Step-Up Adapter Charger Cable Compatible with Milwaukee, M12, Makita, Snapon, Metabo, Craftsman, AEG Gear (TypeC Stepup 12V 15cm Cable)

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 as it should.

Fits my m12 jacket

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!

Ok

It does output 12V from a PD capable Type C port, however after a few months of use, the PVC jacket around the wire split open. I do use this in my jacket while at work, and I am not gentle on my work-wear, however, I feel better quality materials could have prevented this.

Instead of having the bulky milwaukee battery and adapter in your pocket, this cord converts it to USB c. So now I can use any of my portable chargers. Depending on size, lasts all weekend and more. Best thing ever. And priced right.

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.
