The EK1 is Skilhunt's take on a twisty keychain light in the style of the CooYoo Quantum. It has USB-C charging, optional high CRI, and a larger battery than most, but the battery isn't field-replaceable.

The Wuben B2 is a well-priced, efficient bike light powered by a 21700 battery and equipped with USB-C charging. It has a lot of offer, but it won't be for everyone

Few flashlights are also good USB powerbanks. Even fewer good USB powerbanks are also good flashlights. This floody, somewhat pocketable model manages both, with a side of mulitcolored aux LEDs.

The Thrunite Archer Mini is a small flashlight with USB-C charging and a very green LED

The Thrunite TC20 v2 is a powerful, efficient general-purpose flashlight with a large battery and USB charging. It includes some minor improvements over the original including more throw and a USB-C port.

The Nitecore T4K is a compact light with a keychain attachment, USB-C charging and a 4000 lumen burst mode, but is it practical?

The Thrunite T2 is a 1x21700 flooder with the highest efficiency I've ever tested in a flashlight. It features USB-C charging, and can be put in a pants pocket in a pinch.

The Nitecore MH10 v2 is a general-use flashlight powered by a 21700 Li-ion rechargeable battery, with onboard USB charging, and the ability to use a great many different sizes of Li-ion cells.

The Wurkkos FC11 is a very compelling entry-level flashlight, with an 18650 battery included, USB-C charging, a strong tailcap magnet, and an LED with very good color rendering.

The Xtar ST2 is a USB-C PD fast charger for larger cylindrical Li-ion cells. It can charge two cells at up to 4A and has indidivual temperature sensors to prevent overheating. Its performance is impressive, but mine proved unreliable.

The Wuben T102 is a 1x26650 light with an XHP70 emitter, large reflector for respectable throw, sensor-based thermal regulation, USB-C charging and a boost driver that could provide stable output as the battery drains. Unfortunately, it doesn't, dropping to half output unless the battery is fresh off the charger.
