Although it's not going to harm your batteries, I would be doubtful (as an example) that a single Dewalt battery is going to power a fridge for any sustained length of time.The measured output voltage was 12.65V which is perfectly acceptable (a car battery output typically varies between 12 and 14V) and the claimed 12A capacity will be useful.At the right price this could be a useful adapter. ## Frequently Bought Together - TONSIM Adapter for Dewalt 18V Battery Adapter 18V to 12V Step Down Converter with Cigarette Lighter Connector for Using All Car Appliances Compatible with all Dewalt Battery Flexvolt/XR 18V Battery - Pindex High Pressure Self Priming Water Pump with Pressure Washer DC12V 100W, Diaphragm Water Pump with 6m PVC Hose for Car Home Garden Cleaning --- ## 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.pl/products/600754942-tonsim-18v-adapter-for-dewalt-battery-step-down-converter-to](https://www.desertcart.pl/products/600754942-tonsim-18v-adapter-for-dewalt-battery-step-down-converter-to) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-25*
