DARKBEAM UV Flashlight 365+395 Blacklight, LED EDC Flashlights high Lumen USB C Rechargeable Woods Lamp, Mini Magnetic COB Red Light - Emergency Power - Urine, Scorpion Detector, Cure Resin
This small handheld flashlight has 2 different UV Leds (one 365nm, one 395nm - Both still in the UVA range). The 365nm light "looks" less bright, because the human eye can't see it as well, but I found it caused UV sensitive paint and fibers to fluoresce very well. The 395nm light is recommended for curing resin. [Or, you could use both lights at the same time, as they are independently controlled.]
It also has a "side light" which is controlled by a third button, and cycles through 3 modes [White, Red, or flashing red]. The base of the unit has a magnet, and sticks well to metal surfaces.
It charges via a USB-C port (the package includes a USB-C to USB-A charging cable). Note that it will NOT negotiate or charge via a USB-C Power Delivery (PD) charger. You must have a USB-A to USB-C cable that provides 5 volts for it to charge. [The maximum draw I saw was 0.8 amps when charging.]
A single (365nm) UV light had a runtime of 3 hours before starting to dim. It took around 5 watt hours to re-charge the flashlight (~1,000 mAh at 5 volts), so the battery capacity is probably in the 4 - 4.5 watt hour range.
It has an "emergency powerbank" function (a USB-A port that can deliver 1 amp at 5 volts). I did not test how much of the 4-5 wh capacity you could get out via this port, but my best guess having looked at similar devices is that it would only be able to deliver 30 minutes of charging time (2.5 wh).
At this sub-$20 price point, I was favorably impressed with the feature set of this flashlight.

Does it create ozone? Kill bacteria

[@summetj]

It is 365 and 395 nm, not 160-240 nm, so it should not create (much) ozone and probably doesn't kill (much) bacteria. [On the plus side, it is more "eye-safe" than true shortwave UV.]
