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. SuperMini uses high-density battery cells to pack more charge capacity into a smaller, lighter form factor. While a portable charger would need three typical cells to reach 10,000mAh, SuperMini achieves the same capacity with just two of these high-density cells. SuperMini features an 18W USB-C input/output port compatible with Power Delivery (PD) technology. There is also an 18W USB-A output port with ZEN+ 2.0 adaptive charging, which is compatible with Quick Charge 3.0 devices.
