Dual USB-C 40W charger pack

This Essri pack supplies two wall adapters each rated for 20W output over USB-C PD 3.0. The pair is aimed at households or travellers who want a dedicated fast charger for every phone or tablet without swapping cables. Each brick delivers the full 20W whether used alone or together, so two devices charge at speed simultaneously.

PD 3.0 20W per port

The single specification that decides fit is the 20W PD 3.0 capability on every USB-C port. A device that negotiates PD 3.0 at 20W will reach 50% in roughly 30 minutes on an iPhone 16 or 45 minutes on an iPad Pro 13″ (2025). Without PD 3.0 support the port falls back to standard USB rates, so check your device’s charging protocol before buying.

Sustained 20W without throttle

Under continuous load both ports maintain 20W each for the full charge cycle rather than tapering after a short burst. The built-in smart chip regulates temperature in real time, preventing the thermal throttling that cuts power on lesser adapters. This means an iPhone 16 and a Galaxy S25 can both sit at peak rate from empty to full without the charger overheating or reducing current.
