FOLOMOV EDC C2 flashlight review, 525 lumens & rechargeable USB battery. Just 12.4g!
The battery size IS difficult to find replacement when It fails…
14250s (“½AA”) aren’t too bad to find. Should fit directly or maybe loosely, but you’s need an external charger.
They took the intesting part (3000K E21A) out of the light and left all the crap in (e.g. high standby drain).
Small batteries die faster…. Yes as other said difficult to find and expensive
