40W Four-Port USB Wall Charger

The ONITOON 40W wall charger delivers up to 40 watts of total power across four USB-A ports. It supports Quick Charge 3.0 on one port at 3.1A for compatible phones. The unit accepts 100-240V input at 50-60 Hz for worldwide use. It is finished in white and ships as a new product.

Sustained multi-device charging behaviour

When four devices draw power simultaneously the 40W budget is shared between the ports so each device receives a lower current than when charging alone. The Quick Charge 3.0 port maintains its higher voltage profile only while the total load remains within the 40W limit. Built-in safeguards protect against over-current over-voltage and short-circuit during extended sessions.

Compatibility checks before ordering

Verify that your cables have USB-A connectors because the charger provides four USB-A ports only. Confirm that your devices can charge from a standard USB-A source without requiring USB-C Power Delivery. Ensure you have a suitable mains socket for the fixed prongs as no interchangeable plug adapters are included.

Do I need to supply my own cables for the USB-A ports?

Yes, the charger provides four USB-A ports rated at 3.1A total; you must use your own USB-A to Lightning or USB-A to USB-C cables for each device.

Will the 100-240V input let me keep using my older 5W travel adapters abroad?
