The Skilhunt EK1 is a keychain flashlight with USB-C charging optional high-CRI, and a two-position twist switch. It resembles the previously popular CooYoo Quantum and similar lights from other brands, but has a larger battery and modern charging. Unfortunately, the battery is not field-replaceable.
This design pattern started with the CooYoo Quantum in 2015 and many companies have made their own versions since. All of them are nearly the same, varying mostly in emitter options and minor cosmetic features.
