Works great. I bought a second one. *by R***S on February 22, 2026* Can Charge just about anything. ### ⭐⭐⭐⭐⭐ Convenient and universal; works with gumstick-type batteries *by V***R on January 15, 2026* Works as intended; convenient color-coded light indicator; the spring-loaded terminal allows charging any type of battery, as long as +/- terminals are on opposite ends (including flat "gumstick" batteries, which is what I need it for). Plugs in through universal USB-C connector, which is also convenient. ### ⭐⭐⭐⭐ Good product for the price *by K***I on December 11, 2025* This is a great charger. I bought this specifically for C batteries so it was a good deal for what it’s for. My only concern is the batteries seem loose when you put them in to charge and you have to have a block or something to plug this into with a usb. Most my other batteries chargers I have plug into the wall so it’s less space but this does not so that’s a little more of an inconvenience in my opinion. Charges great though! ## Frequently Bought Together - BONAI Battery Charger for 1.2V Ni-MH Ni-Cd AA AAA C D Rechargeable Batteries, All Types of 3.7V Lithium Batteries - 2 Slots USB Charger - HQRP 2-Pack Gumstick Battery Compatible with Sony NC-5WM, NC-6WM, WM-701C, 1-528-231-11, WM-RX707, WM-F100, WM-FX675 --- ## 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.jp/products/219966359-battery-charger-for-1-2v-ni-mh-aa-aaa-c](https://www.desertcart.jp/products/219966359-battery-charger-for-1-2v-ni-mh-aa-aaa-c) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-05-23*
