DC 5.5*2.1mm to USB-C PD Adapter

This adapter converts a 5.5*2.1mm DC barrel jack into a USB-C Power Delivery output. It accepts an input range of 10.5V to 32V and delivers up to 45W maximum power. The unit supports multiple fast-charge protocols including PD, QC 2.0, QC 3.0, DCP, PE+ 1.1, PE 2.0, FCP, AFC, SFCP and SCP.

Suitable for 45W USB-C devices

It powers 45W laptops such as MacBook models, tablets and phones that charge via USB-C PD. The adapter negotiates voltages of 5V, 9V, 12V, 15V and 20V at up to 2.25A. Users needing more than 45W or a different DC plug size should look at other options.

45W maximum output limit

The single specification that decides fit is the 45W maximum output rating. A source capable of at least 45W is required to reach full adapter performance. Devices demanding higher wattage will not charge at their rated speed with this unit.
