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 Acebeam EC35 II (SST-20) is a duty/tactical light with high CRI, a decent amount of throw, USB-C charging, and a powerbank function.

The Acebeam TK16 is a 1x16340/CR123A everyday carry light with three emitters and a tail e-switch. It resembles a cross between a Lumintop FW3A and an Olight S1. It combines excellent power efficiency, class-leading max output, and very good color rendering.

The Lumintop FW3A is the result of two years of development on enthusiast forums BLF and TLF. It's one of the smallest 18650 flashlights, with three emitters, a tail e-switch, an open source firmware, and a firestarting 2800+ lumen burst mode. It already offers four LED options, with more to come, has great ergonomics, a fantastic user intefrace, optics that are nearly as easy to change as the battery, and no glue anywhere. Did I mention it's under $40? It's under $40.
