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! --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.lk/products/594683208-12v-heated-jacket-battery-step-up-adapter-charger-cable](https://www.desertcart.lk/products/594683208-12v-heated-jacket-battery-step-up-adapter-charger-cable) --- *Product available on Desertcart Sri Lanka* *Store origin: LK* *Last updated: 2026-07-31*
