Review: Really Impressive Charger, Big Upgrade from My Old One, Speedy, Easy, and Informative! - As someone who hadn’t upgraded their 18650 charger in quite a while, this UMS2 feels like a huge step up. The design is sleek and compact, yet it delivers an impressive amount of information, showing not just charge status and level, but also how long it’s been charging, the total capacity charged, the rate, and even the battery’s health. It’s packed with intelligent features, automatically detecting battery size, type, and optimal voltage, and adjusting the charge rate based on power input. You can still fine-tune settings manually if you want, which is a nice touch if needed. The USB-C connection makes it more universally compatible (though note it doesn’t come with a wall plug), and the included 2-battery organizer case is a nice bonus. Charging speed is much faster and more consistent than my older LUC D2, and the spring-loaded battery bays are smooth and easy to adjust for different sizes. The wide compatibility with various battery types and material builds makes it a very versatile tool for home use. My only minor wish is for an auto-off feature, but otherwise it’s silent, efficient, and very well-designed, at a great price for the value. Hopefully it holds on just as long as my old charger as well! So far, I’m thoroughly impressed and would definitely recommend! ## Features - FAST AND EFFICIENT CHARGING- Reach a maximum total of 4000mA for two slots, 3000mA for one slot when pairing with a 9V QC2.0+ output USB power source.
