However the green light quit working but it still charges the battery great and well, basically if the red light goes out then you know the battery is fully charged so green light being on is not a big concern for me. ### ⭐⭐⭐ Hot charger melted a hole, and stopped working. *by K***S on Reviewed in the United States on May 5, 2019* But it lasted me 7 months so i cannot complain too much. Im buying another until i can find one with a fan ### ⭐⭐⭐⭐ Seems to work as advertised *by 9***N on Reviewed in the United States on May 2, 2019* While I have only used it once, it worked as expected. One enhancement which would be nice is if it indicated how full the target battery was via an LED array or a blinking LED or a colored LED. --- ## 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/171856468-54-6v-3a-charger-48vdc-output-54-6v-48volt-replacement](https://www.desertcart.pl/products/171856468-54-6v-3a-charger-48vdc-output-54-6v-48volt-replacement) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-31*
