The next superstorm could strike anytime. If you're concerned about having electricity, the MetAir Solstice packs a whopping 55,000 mAh of power.
This portable charger from QuantumSphere has power equivalent to 115 D-cell batteries under a 2 amp load.
It's being billed on a Kickstarter campaign as the world's most powerful portable device charger.
The 3.9-poound device has three USB ports, LED lights, and an emergency radio.
It can charge an iPhone 5 at least 20 times. It can also provide light for 6 hours a night up to 12 nights in a row, according to the campaign.
Once exposed to air, the five zinc-air cells can generate current.
The plug-in cartridge is available for $49, with the MetAir Solstice itself going for $99 on the ambitious Kickstarter campaign, which aims to raise $179,000.
