Review: All good - All good Review: Works well wired to 24v to 12v converter - I use this in my overlanding setup. I have a 24v system in my Toyota landcruiser and I needed somthing to connect from my 24v to 12v converter to charge an auxiliary battery. In my situation, my alternator puts out 24v, that will fry this thing. So! I wired it to the output of my converter (12v out). I asked the question before buying this and everyone said 'no it won't work'. I bought it anyway cuz my options were limited. Well, it works. My aux battery has been staying charged while I drive and my fridge freezer has been staying cold. Mission accomplished. ## Features - 【Compatible Multiple Battery Types】 Compatible with a multitude of alternator types, the Renogy 12V DC to DC charger offers correct charging for AGM, Flooded, Gel, and Lithium batteries. - 【Smart Multi-Stage Charging】 The 20A DC to DC smart charger will charge your house batteries from the starter battery by 3-stage charging (Bulk, Boost, and Float), to make sure it optimally and automatically charges to 100%. - 【Various Protections For Ultra Safety】 The Renogy on-board battery charger with high-quality offers Over-voltage Protection, Over-temperature Protection, and Reverse Polarity Protection to ensure the operation safety.

Mission accomplished. ### ⭐⭐⭐⭐⭐ Perfect to charge 2nd house battery for 12V car fridge *by G***E on 8 August 2023* This is exactly what I wanted and worked exactly the way I wanted it to. I got a 12 V DC car fridge for our 4,000 mile, 2 week road trip. I installed a 2nd “house” battery in my vehicle and used this to charge the 2nd house battery while we were driving. The house battery ran the fridge during the night while we were stopped, and got charged during the day while we were driving. I never drained my primary battery for starting my vehicle. This product perfectly charged my battery at the optimal voltage and current limit to prevent overheating the battery and prevent overloading the alternator on my vehicle. Since both batteries and the charger were in the engine compartment, I installed a switch so I could turn off the charger in slow traffic when there wasn’t good airflow, then turned it back on at highway speeds. This product was exactly what I wanted. Hopefully it lasts a long time, I really like it. Instructions were good. I basically installed it just like the instructions and diagram showed. ## Frequently Bought Together - Renogy 12V 40A DC to DC On-Board Battery Charger for Flooded, Gel, AGM, and Lithium, Using Multi-Stage Charging in RVs, Commercial Vehicles, Boats, Yachts, 40A - Sanuke 4 AWG - 3/8" Battery Terminal Connectors, Copper Wire Lugs Assortment Battery Cable Ends with 3:1 Heat Shrink Tubing - GearIT, 4 Gauge Wire, for Automotive Power/Ground, Battery Cable, Car Audio, RV, Amp, CCA Wire, Wire, Automotive Wire, Battery Cables, Amp Wiring Kit, (25 feet Each- Black/Red Translucent) --- ## 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.tn/products/320556035-renogy-12v-20a-dc-to-dc-on-board-battery-charger](https://www.desertcart.tn/products/320556035-renogy-12v-20a-dc-to-dc-on-board-battery-charger) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-08*
