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.
I like this light enough to leave it on my keychain, and I don’t usually like extra stuff on my keychain.
