OLight do a range of quality lights, as do Fenix and lots of others. Having a magnetic charging capability is really handy, it has to be said; I’ve got a PowerTac flashlight with that facility, and it beats having to take the battery out to recharge it – there are some with USB-C charging as well, although some, like Imalent have taken a different tack and developed their own high-discharge cells with a USB-C port to charge the battery, which is easier than needing a charger that plugs into the mains.
Edit: I’d forgotten that there are USB charging leads which have a pair of magnetic contacts on each end, so you can charge any Li-ion cell easily, from a car USB port, or a powerpack. Fenix and OLight do them.
