It’s the stuff of horror movies: you’re out camping in the wilds and hear a rustling in the bushes, but when you whip out your flashlight to investigate the source of the noise, you discover that the battery has gone dead. Campers who invest in a Bun Bun Eco Light can spare themselves such nighttime terrors: when the power begins to give out, simply snap the two hinged sections at a right angle and begin spinning it around like an old-school football rattle. Not only will you recharge the flashlight, you might also bop that hungry bear on the nose while doing so.

Bun Bun Eco Light, ¥2,100. Available from branches of Tokyu Hands, Village Vanguard and outdoor stores.
