NESTOUT

NESTOUT builds camp power as a system: rugged, weather-sealed batteries at the core, and screw-on attachments that turn the same battery into other tools — the LAMP-1 lantern, FLASH-1 light, FAN-1 fan and PUMP-1 air pump all run off it. It comes out of Japanese electronics maker ELECOM, designed for dirt rather than desks.

Start with a battery — 5,000 to 15,000mAh for pocket gear, or the 700N power station for base camp — then add the attachments you'll actually use and a 2- or 4-panel solar charger to keep it topped up. Gear cases, outdoor-rated cables and the clip-anywhere carabiner battery round out the kit, and the bundles package the popular combinations at a discount.
