The biggest little portable charger. Charge your phone 2-3 times with 18W power delivery.
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.
