Today, Mophie has released two new power banks with USB-C and USB-A. The smaller version of the Powerstation has a 10,000 mAh battery, while the Powerstation XL has twice that capacity with its 20,000 mAh battery.
Both have two USB-A ports and one USB-C with PD fast charging of up to 20 W, which is enough to charge a phone or iPad at best. However, it may take quite some time to charge a laptop, although it is possible.
If all three ports are used simultaneously, you get a combined output of up to 15 watts. According to Mophie, the Powerstation can fully charge an iPhone twice, and the Powerstation XL can do it four times.
