Reddit reviews Eebuy Selfie Ring Light with Phone Holder for Live Stream and Makeup

Three big problems here.

1. No light you get is going to be "chargeable with mains." You'll need either a USB adapter (if you get a rechargeable light) or an external charger, which often does plug into the wall.
   
   
2. Flashlights are not for self defense. You'd be better off just running away. If you want an 100 lumen light you can defend yourself with, get a 6 cell Maglite (£35.99).
   
   
3. 100 lumens is relatively weak. Most 18650 lights can get up to 1000 lumens.
   
   I don't know anything about what is or isn't allowed in the UK, but if you're dead set on getting a flashlight, a Convoy S2 is the go-to cheap light around here. This link has it and a battery for 15 pounds. Here's a charger for 7 pounds.

Found this comes with a battery, what do y’all think
