Stop whatever you're doing and check out this $99 fuel cell-powered portable charger
Chances are that 99% of all portable smartphone chargers you might bump into will rely on a Li-Ion battery to store all that spare juice. From time to time, however, an ingenious product arrives with the true potential to amaze us. Such a gadget is this new smartphone charger, which is currently looking for funding on Kickstarter.
See, it does not sport a battery inside, but a compact fuel cell, which will produce a steady electrical current by disintegrating chemicals leaving water and heat as by-products after the reaction. Simply put, it's a miniature power plant that can fit in your pockets. "Recharging" the kraftwerk powerbank takes just 3 seconds, which will henceforth enable you to fully charge your iPhone 11 times, as the Kickstarter page of the charger puts it. The charger is completely power grid-independent.
Its tank stores up to 200ml of fuel, which is enough to provide power output varies between 2W and 10W, which means that it will charge your device with a current that deviates between 400mA and 2,000mA, which is similar to what you normally get from most chargers. The willing adopters can back kraftwerk and score a fuel cell mobile charger for $99.
