Model SPE-PD-20W
 
This AC adapter automatically detects the voltage and current required for a connected gadget due to the Power Delivery protocol. This allows the adapter to charge devices three times faster than usual while protecting them from overheating and thus extending battery life. In addition, the adapter is reliably protected from short circuits, current overload, overheating, and overvoltage. New technology in a classic form factor!
