XTAR MC1 Portable Li-ion Battery Charger Simple, Compact, and Reliable Battery Charging If you're like me, then you like your devices to do exactly the job they're designed for—nothing more, nothing less—and that's exactly what the XTAR MC1 accomplishes. The MC1 is a single-slot lithium-ion battery charger that charges at a steady 0.5A current and supports up to 13 different battery types. It isn't packed with unnecessary extras or complicated features. Instead, it focuses on delivering straightforward, dependable charging for everyday users. Powered entirely by USB, the MC1 is incredibly compact at under four inches long and slim enough to fit easily into a travel bag, toolbox, or gear kit. Most flashlight owners don't need a large multi-bay charging station, and the MC1 offers a practical and affordable alternative that handles the essentials with ease. Advanced Safety in a Minimalist Design Despite its small size and simple appearance, the XTAR MC1 includes many of the safety features found in more advanced chargers. Its fire-resistant ABS plastic construction and open-air cooling design help prevent overheating and ensure safe operation. Zero-volt activation technology can slowly revive over-discharged batteries, while reverse-polarity protection safeguards against incorrect battery installation. The spring-loaded charging contact eliminates the need for spacers and automatically adjusts to fit a wide range of battery sizes. Best of all, because the charger is USB powered, you can charge batteries almost anywhere—simply connect it to a computer, power bank, USB wall adapter, or any powered USB source and you're ready to go.
