Description
Nitecore MC21 Magnetic Charger
Part of the Nitecore 21700 Intelligent Battery System
The Nitecore MC21 is a magnetic charger designed to recharge the Nitecore NL2150HPi, a high-drain 21700 battery that's exclusively found in the Nitecore i4000R. The MC21 has a magnet embedded at the end so that it fits safely and securely onto the terminal of the battery. From there, all you need to do is plug in a USB-C cable and you're battery is instantly charging. There's a LED charging indicator that glows red during the charging process and blue when the battery is ready-to-go. No need to lug around a giant charger, when all you need is a small, tiny magnet to completely charge your battery. This magnetic charger is also compatible with the Nitecore NL2140HPi.
