What it does

This adapter converts a DC 7.9mm x 5.5mm barrel input into a USB-C male output using a built-in PD identification chip. It is designed for users who want to power USB-C laptops, tablets or phones from an existing barrel-type PD charger rated at 65W. The compact form factor weighs 0.009 kilograms and fits easily in a pocket or bag.

Who it suits and who it does not

It suits owners of USB-C devices who already have a compatible 65W PD barrel charger and want a lighter travel setup. Buyers who need more than 65W of delivered power should look at something else. Anyone without a suitable PD source cannot use this adapter.

The deciding specification

The adapter requires a PD charger that can supply at least 65W and accepts a 7.9mm x 5.5mm barrel plug with a 0.9mm centre pin. If your charger uses a different barrel size such as 7.4mm x 0.6mm or 7.5mm x 0.9mm, the connector will not fit.

Questions about this item

Does the package include the 65 W USB-C PD charger or only the 7.9 mm × 5.5 mm female-to-USB-C male adapter?

Only the adapter is supplied; a separate 65 W USB-C PD charger must be provided by the user.

Which barrel-plug size does this model accept — 7.9 mm × 0.9 mm, 7.5 mm × 0.6 mm or 7.4 mm × 0.6 mm?

The adapter is built for a 7.9 mm × 5.5 mm (centre pin 0.9 mm) DC input; other sizes are not compatible.

If my laptop’s original supply is 19 V 3.33 A (65 W), what charger rating do I need with this adapter?

Use a USB-C PD charger rated at 65 W or higher so the adapter can deliver the required power.
