https://www.amazon.com/TAIFU-Adapter-Compatible-Charger-Balance/dp/B0DNJDK5JN You basically just need a DC adapter. But if I can't return the item Do not settle. Push hard for an exchange/refund. The Hota D6 (HOT-D6) isn't even manufactured anymore, and any units you find are just old inventory. Someone bilked you. This is entirely on them. You paid extra to receive the AC-compatible unit, which includes a built-in AC/DC converter. They can't just cheat you out of the additional hardware. If they refuse, get your credit card involved. Once they have a chargeback hanging over their head, they'll roll out the red carpet for you and get it replaced. It's very annoying to have to submit a dispute, but some companies just won't listen until they have to pay additional fees.
