Smaller than a credit card, the new Zendure SuperMini is the smallest and lightest portable charger out there. The SuperMini uses high-density battery cells to pack more charge capacity into a smaller and lighter case. This external charger packs a serious punch with a couple of days’ worth of energy and pass-through charging allowing you to charge your device while the SuperMini is still connected to a power supply. Besides being super small, it’s also super fast, capable of bringing an iPhoneX up 50% in just 30 minutes. Available in three finishes — silver, black and blue horizon — you can throw your weight (and change) behind these minuscule chargers on Indiegogo right now and get a USB-A and USB-C combo cable as well as a two-year warranty. And to top it all off, if you fund the project early, you’ll get 56% off of the retail price.
