DC 4.5 x 0.6 mm to USB-C power adapter

This adapter converts a DC 4.5 mm x 0.6 mm female input into a USB-C male output with Power Delivery support. It targets users who want to power USB-C laptops or devices from an existing barrel-style charger. The built-in PD identification chip negotiates 5 V, 9 V or 20 V output automatically. Input voltage range is 15 V to 20.5 V with a maximum output of 100 W.

Fits between a barrel charger and a USB-C device

The unit sits inline between a DC 4506 power source and a USB-C laptop, phone or tablet. It removes the need to carry a separate USB-C brick when a compatible barrel adapter is already available. The adapter requires the source charger to exceed the device’s power draw; a 90 W source will not run a 90 W load. Weighing 0.01 kg, it adds negligible bulk to a travel kit.

Replaces a dedicated USB-C power brick

Users migrating from barrel-charged laptops to USB-C models can keep their existing DC 4506 chargers instead of buying new USB-C units. The step up makes sense when the current charger delivers more watts than the laptop requires, such as a 90 W adapter for a 65 W or 86 W system. It is not suited for devices drawing over 100 W or for setups where the source cannot exceed the load.

Questions about this item

Will the adapter limit output voltage to 20 V when my laptop draws full power?

The built-in PD chip negotiates 5 V, 9 V or 20 V output; 12 V and 15 V are not supported, so sustained loads run at 20 V up to 5 A.

Does the adapter get hot or noisy when used continuously at 100 W?

The unit is a passive connector with an internal PD chip and no fan; it produces no audible noise and only minimal warmth during normal operation.

What DC barrel charger must I already own for this adapter to work?

You need a DC 4.5 mm × 0.6 mm female-input charger rated 15 V–20.5 V with power greater than your laptop’s draw (e.g., a 90 W charger for a 65 W or 86 W laptop).
