if you actually need a flashlight every day for work or whatever then you should carry a proper flashlight. otherwise, just use your phone. if you absolutely must have a separate flashlight but you don't actually need to use it daily, then a powerbank with a built-in light. if you already have a powerbank with no light, then a usb light.

that shit in OP image is e-waste, guarantee the non-replaceable battery will be toast in just a couple years if that long, the shitty hinge/clip will break, and it probably has some stupid SoS mode and you keep clicking the button but it has to cycle between 12 modes before it finally shuts off.
