When you're off the grid, but still need to power your essential devices, Bruntion's reusable Hydrocore 4-pack can keep you going with safe and environmentally-friendly technology. Designed specifically to be recharged in the Brunton Hydrolyser Recharge Station and used in their Hydrogen Reactor, the Hydrocore absorbs hydrogen and bonds it with the proprietary metalhydride metal lattice core to become a high-density solid-state energy storage cartridge with a 4000mAh output that replaces up to fifteen AA-batteries. Unlike chemical batteries, the Hydrocore's non-toxic solid-state construction has no natural discharge, so it will hold all of the energy until you need it.
