Well, not just air, but zinc and air. Combined they form what Metair Power is calling the “world’s most powerful disposable battery.”

It’s about time we get some competition in a field that has been dominated by big corporations that have cornered the market, and battery prices just seem to go up and up.  Here we have a product that requires less material, is cheaper to ship, provides more power, is more efficient than any battery on the market, and they’re just getting started!  Once production is in full swing, who know’s what kind of effect this will have on battery storage industry, but it can only be good for the consumer.  

It works by oxidizing zinc with oxygen from the air and creating an electrical current. You 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, and you’re ready to go again!

The unit has two USB ports, an array of red and white LED lights, hazard flashers, and a strobe.

Met Air is seeking funding through a Kickstarter campaign to get production volume up for the first order.
