Does it really charge 50% in 30 minutes?

PD, also known as power delivery, has the ability to charge devices more than 2.5x faster than a standard charger. It will allow for rapid recharge speed up to 3x faster. Power your iPhone 11 from 0% to 50% in just 30 minutes using the USB C output at the bottom of the PowerPack Mini. This charging speed is only true for PD, not Qi wireless.
