I’m not sure all the models in particular that have built in USB-C charging because I don’t charge batteries inside of flashlights, but in general, I would rate Acebeam as makers of top tier flashlights. Manker flashlights are also of superior quality, but often the UI makes them less appealing to me, personally. There are pitfalls to easily get stuck cycling through a series of blinking modes, which annoys me. Acebeam UI’s are typically simple and effective. Astrolux flashlights are good quality too, don’t get me wrong, but they’re not, in my experience, on the same level as the other two, often due to design choices (prematurely timed brightness step-downs being a common issue), or so-so build quality.
