Because sometimes rechargeable batteries alone just don’t cut it when you need constant and reliable backup power: The MetAir Solstice is the world’s most powerful disposable battery (by size and weight). Our custom designed zinc-air battery cartridge, turbo charged with advanced nano-catalyst, supplies 60,000 mAh at 5.0 volts and more than 190 watt-hours of stored energy in a compact 2.2 lb. form factor. The MetAir Solstice packs enough energy to charge an iPhone 28 times, charge an iPad 6 times, or power the ultra-bright LED lights for 125+ hours. The MetAir Solstice has two integrated USB charging ports, an ultra-bright array of white and red LEDs for ambient lighting, hazard flashers, and strobe. During critical times – when you’re voluntarily or involuntarily without power – fuel may not be available for gas generators, and the sun and wind may not be available to charge traditional rechargeable lead acid or lithium ion batteries with solar panels or wind turbines. The MetAir Solstice delivers on-demand power for your most critical devices – phones / tablets to stay connected, informed, and entertained – when and where you need it most.
