Orca Display 2 contains a large 9500mAh battery. Regular USB chargers, and incompatible fast charging standards may charge the display slowly, at around 8-12 hours from 0% to 100%.
To charge the Display 2 quickly, you need to use a compatible PumpExpress USB-C fast charger, and a high-quality USB-C cable. We also recommend to use a short USB-C cable, ideally 1 meter or shorter. With a compatible fast-charger, the Orca Display 2 will charge from 0 to 100% in ~4 hours.
