SuperMini is a credit card size 10,000mAh portable charger, which can be easily put in your pocket and extend your phone usage for 2-3 days. With 18W Power Delivery, it can fast charge your iPhone X up to 50% within 30 mins.
One of the most popular portable charger capacities is 10,000mAh. This will generally give you a few days’ worth of mobile phone recharges. But many people go with a smaller capacity because they feel that a typical 10,000mAh charger takes up too much space. That’s where SuperMini comes in.
SuperMini is 30% smaller than a traditional 10,000mAh external battery, so it fits in virtually any bag or pocket. Here’s how we did it. SuperMini uses a type of battery cell called 21700. Each cell provides 5,000mAh of charge capacity, making them 50% more energy dense than the cells used in typical chargers. It takes just two of these cells to reach 10,000mAh, while most portable chargers use three cells.
SuperMini also supports up to 18W of fast charging capability through both its USB-C port and USB-A port. With up to 18W of Power Delivery (PD), SuperMini can charge iPhone X up to 50% in 30 mins with a USB-C to Lightning cable.
The USB-C PD port also enables rapid 3- hour recharge performance. A standard external battery may take more than five hours to recharge at 2 amps. Its USB-A port supports ZEN+2.0 with Adaptive Quick Charge, taking advantage of the rapid-charging capabilities of compatible QC 3.0 devices
