Good adapter
This adapter works great with my jacket!

Works exactly as it should, not a bad price.
This works with my 7.4 volt heated gear, both my vest and long underwear, which are different brands. It’s great because I can plug into a larger battery. You want to make sure you have an extension cable because larger batteries are well, larger.

I’m happy with this purchase
I’m so happy I purchased this adapter. I purchased a heated coat for my father, he lost his adapter and this one perfect.

Unreliable, poor connection , DO NOT BUY
Do not buy this!! Terrible quality! Poor connection! You can’t move the chord or battery without it shutting off. Hard to take a video while demonstrating but every time I put the battery in the pocket it would shut off. I’m so tired of everything being this awful throw away quality.

Must have for heated jackets!
Works great to adapt your heated vest or jacket to any (high output) usbc battery pack. We have several vests/jackets that use the same plug and it's very handy to be able able to go to a rodeo or all day sporting event and have several non proprietary battery banks on standby or just to use a higher capacity bank than comes stock. If you have heated accessories and need long usage times, you need one of these plug adapters.
