Oxidation of zinc

The MetAir Solstice is built for outdoor enthusiasts, emergency preppers, families, and students, the Solstice is a personal USB power source and portable LED light system, that provides energy to various products in an emergency. This battery design requires no Solar, no Recharging and no Maintenance.

Offering a three-year shelf life, this battery may appear to run on air, but actually requires the oxidation of zinc in order to produce a current. This has been called the “world’s most powerful disposable battery.”

One would insert a large cartridge into the unit, removing a covering to expose the zinc chemicals.

The company compares it to a chemical hand-warmer pack that once exposed to oxygen goes into a chemical process that produces heat.

How much power? The Metair Solstice is cited to produce 60, 000 mAh at 5.0 volts, and it gives more than 190 watt-hours of stored energy. That’s enough to give off 125 hours of ambient light or charge an iPhone up to 28 times, the company touts.

You swap in a new cartridge once it’s used up.
