Four-Port USB Charger

This 40W USB charger provides four Type-A ports for phones and tablets. It accepts a DC 24V input from the included power adapter. The unit suits travellers and desk users who need to charge several devices from one outlet.

DC 24V Input Limit

The charger only operates from a 24V DC source, so it cannot plug directly into mains sockets. The supplied adapter handles that conversion. Without the adapter the ports deliver no power.

40W Shared Across Four Ports

Each port can supply up to 2.4A at 5V while the total output is capped at 40W. Four phones drawing 2.4A each would exceed the limit, so charging slows when all ports are heavily loaded. Tablets and large phones get priority when fewer devices are connected.

Questions about this item

Should I pick the 40 W four-port model or a single-port charger for my phone and tablet?

The 40 W four-port unit delivers up to 2.4 A per USB-A port, so you can charge a phone and an iPad together without swapping cables.

What does the 40 W rating actually give me when I plug in an iPhone 14 and a Galaxy S23?

Each port supplies 5 V at up to 2.4 A, so both phones draw their maximum supported current simultaneously while the total stays within the 40 W limit.

The charger takes a 24 V DC input — what does that cap in practice?

The 24 V DC input feeds the internal converter that produces four 5 V USB-A outputs, limiting combined draw to the stated 40 W across all ports.
