I have a parasitic load on my system but it's not this DC DC charger. I pulled the charger out of the system and still had the same discharging of my batteries I was attributing to this charger. Adding the charger back into the system and no detectable difference to this discharge rate. This charger works great and it's easy to set up and modify the charging parameters through the app; which I really appreciate. Easy to set it up so it keeps my LiFePO4 house batteries at ~80% while my boat sits during the week. ---- old review ---- Charger works as advertised but there is a much larger than anticipated parasitic load when not charging. I estimate it to be about 1 amp. Drained a 100Ah AGM dual purpose battery from 12.7 to 12.0V in ~48 hours. Anyone else experiencing this? Is there a fix (softwear or otherwise)? This charger isn't useful for marine applications where there are often days to weeks between motor use with this magnitude parasitic load. Review: Read some bad reviews on this but have ran Renogy DC/DC for years (get new ones when I upgrade or change vehicles) and never had one problem. ## Features - ๐’๐š๐Ÿ๐ž๐ ๐ฎ๐š๐ซ๐ ๐’๐ญ๐š๐ซ๐ญ๐ž๐ซ & ๐‚๐ก๐š๐ซ๐ ๐ž ๐’๐ฆ๐š๐ซ๐ญ- Renogy 12v battery charger features built-in alternator detection (charges only when engine runs!) and intelligent strategies.

The instructions are good (Made in USA), app works good, the until has lots of charge profiles and even current limiting. My only disappointment was that you can only choose from 10A increments for the current limiter. We get 10, 20, 30 and 40 and well I need 25... ohh well ## Frequently Bought Together - Renogy 12V 20A DC to DC Battery Charger with Multi-Stage Charging and Bluetooth Compatibility for Flooded, Gel, AGM, and Lithium Batteries in RVs, Commercial Vehicles, Boats, and Yachts - Renogy 40A Set w Holder ANL Fuse, 40 amp (40A ANL Fuse Set w/Fuse) --- ## Why Shop on Desertcart? - ๐Ÿ›’ **Trusted by 1.3+ Million Shoppers** โ€” Serving international shoppers since 2016 - ๐ŸŒ **Shop Globally** โ€” Access 737+ million products across 21 categories - ๐Ÿ’ฐ **No Hidden Fees** โ€” All customs, duties, and taxes included in the price - ๐Ÿ”„ **15-Day Free Returns** โ€” Hassle-free returns (30 days for PRO members) - ๐Ÿ”’ **Secure Payments** โ€” Trusted payment options with buyer protection - โญ **TrustPilot Rated 4.5/5** โ€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.it/products/687133039-12v-20a-dc-to-dc-battery-charger-with-multi-stage](https://www.desertcart.it/products/687133039-12v-20a-dc-to-dc-battery-charger-with-multi-stage) --- *Product available on Desertcart Italy* *Store origin: IT* *Last updated: 2026-05-13*
