1500ルーメン充電式懐中電灯（自動調光機能付き）

Bought this for camping and the auto-brightness really sold me—it adjusts on its own when I move from the tent to the dark trail, and I never have to fiddle with buttons. The micro USB port hiding under the sliding end cap is a bit stiff at first, but once you get it, recharging is a breeze. Honestl

The sliding USB port on the bottom is such a clever design—no cap to lose, and it charges up pretty fast. I've used it every night for a week and the auto-brightness actually keeps it from blinding me when I point it at something close.

The slide-up charging port is such a simple idea but it makes plugging in way less fiddly than fumbling with a rubber flap. I’ve used it every night for a week and the auto-brightness kicks in exactly when I need it, so the 1500 lumens don’t blind me walking the dog.
