TATTU U1S UV Torch 365nm Black Light Flashlight with ZWB2 Filter, Rechargeable Blacklight 5W Ultraviolet LED Lamp with Micro USB Charging Cable

But, the description is wrong: Batteries included? No <- Yes Batteries Required? No <- YesBut the Li-Ion cell is unbranded, and has about 1600 mAh capacity, which is low, as it doesn't last long. It charges OK in the torch, but not in a 'proper' charger. I replaced it with a decent capacity cell.Still earns a five star rating from me

Best feature is the rechargeable system and it's powerful enough for my applications

Excellent
