Summary
You don’t hear much about JETBeam. That’s a shame, because the long-established company has some interesting flashlights in its portfolio. The new JETBeam E26 (“Kunai”) has just been released.
The E26 was announced a few months ago via a Kickstarter campaign and was successfully funded after just one day. I had the opportunity to test the flashlight before it was officially shipped.
JETBeam made a successful start with the E26 “Kunai” into the world of flat flashlights: white light, UV light and a green laser, combined with intuitive UI using a rotating ring and two buttons, fast charging via USB-C and an ergonomic, practical design.
For the perfect experience I miss direct access to the lowest level, which could also be a little lower. That, and if the flashlight was a little shorter, it would be the perfect EDC flashlight for me. But even as it is, it makes a very good impression.
This review was sponsored by flashlightgo.com, a Chinese shop with a large selection of flashlights.
It's built-in. The back cover is secured with four screws, so I assume you could replace the battery once it's dead. But the seal didn't want to release the cover without force, so I stopped to not damage it prematurely.
It's mentioned several times in the review that the battery is built-in. Not sure what you mean with "omitted from the review".

I have a similar flashlight as my every day carry from OLight and the battery is just integrated into the flashlight and rechargable. Can't speak for the one op posted but I get pretty good runtime, only charging it every few weeks under admittedly light use. (I work retail and use it for looking in between shelves mainly)
I imagine they could use the same batteries they used in cell phones. So many built and wasted.
