Why 20W Dual Charger
What 20W Dual Charger does better.
20 WUSB-C with Power Delivery
18 WUSB-A with Quick Charge 3.0
2devices charging at once
SafeCharge Proprotection against overcurrent, heat and short circuit
20 W Power Delivery
iPhone 15: from 30 to 60% in half an hour.
The USB-C port delivers 20 W to the PD standard, exactly the maximum that current iPhones accept by cable. A Galaxy S24 reaches 53% in the same time.
Measured with iPhone 15 and Galaxy S24.
Two ports
USB-C and USB-A. For new and old devices.
Phone on USB-C, headphones or power bank on USB-A, both at the same time. No swapping plugs, no second power adapter at the socket.
SafeCharge Pro
Safe overnight.
The protection chip monitors current, voltage and temperature and reduces power when needed. Your device only gets what it can handle.
