Two-pack flat wall charger

The package contains two identical 40 W wall chargers, each fitted with two USB-C and two USB-A ports. They are built for households or small offices that need to charge several phones, tablets or accessories from a single outlet. The flat 1.18 inch profile lets the adapters sit behind furniture without blocking the socket.

Build integration and space savings

Each unit plugs directly into a standard 100–240 V AC outlet and requires no extra cables or mounting hardware. The low-profile shape frees the surrounding wall area so furniture can be pushed flush against it. Four ports per charger mean one outlet can serve up to four devices, reducing the need for power strips.

Bundled value and charging flexibility

The two-pack doubles the number of available ports without buying a second product separately. Both USB-C ports support PD 3.0 at up to 20 W, while the USB-A ports deliver up to 5 V/3.1 A for legacy devices. Mixed-port charging lets users connect old and new cables simultaneously from the same block.

Questions about this item

Does the 40W total output drop when all four ports are used simultaneously?

The charger delivers up to 40W total across all ports; each USB-C port can supply 20W maximum while each USB-A port supplies up to 5V/3.1A, so power is shared when multiple devices are connected.

How warm does the flat 1.18-inch thick housing get during all-day charging?

The compact flat design fits behind furniture with cords exiting top or bottom; normal operation stays within safe temperature limits for continuous use.

What cables are required to use both USB-C and USB-A ports right away?

You need your own USB-C to USB-C or USB-C to Lightning cables for the two USB-C ports and standard USB-A cables for the two USB-A ports.
