Awesome little bit of kit. Not only does it charge your cells, but you can also use any cell you have (li-ion only) to charge a portable device. ### ⭐⭐⭐⭐⭐ Very good *by P***Y on Reviewed in the United Kingdom on 17 November 2019* Works like a charm --- ## 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.us/products/63439129-folomov-a1-portable-magnetic-usb-cable-charger-with-charging-discharging](https://www.desertcart.us/products/63439129-folomov-a1-portable-magnetic-usb-cable-charger-with-charging-discharging) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-18*
