100W PD Charging Adapter, DC 7909 (7.9x0.9mm) Female to USB-C Male Connector with Built-in PD Smart Chip for Laptops, Tablets & Phones

Aomoproing 100W DC 7909 to USB-C PD Charging Adapter

The Aomoproing 100W PD charging adapter converts a compatible DC 7909 power connection into a USB-C male power connector. Its DC input uses a 7.9x0.9mm female port, while the USB-C output connects to supported laptops, tablets and phones. A built-in Power Delivery identification chip negotiates a compatible output profile with the connected USB-C device.

Power Compatibility

The DC charger's rated wattage must be greater than the power required by the connected USB-C device. A DC charger and laptop with equal wattage ratings may not operate correctly because of conversion and operating requirements. For example, pair a 90W DC charger with a laptop requiring less than 90W. Do not connect a device requiring more than 100W.

This is a one-way power adapter from a compatible DC 7909 charger to a USB-C device. It does not convert USB-C charger output into DC 7909 power. Before use, verify the charger's DC plug size, voltage, polarity and wattage, and confirm that the receiving device supports one of the listed USB PD profiles.

Compact and lightweight, the adapter is convenient for travel, work or carrying as a spare when a compatible DC power supply is already available.

Frequently Asked Questions

Can this DC 7909 adapter charge a USB-C laptop?

Yes, if the laptop accepts a supported USB PD profile and requires less power than the connected DC charger can provide. Maximum stated output is 100W at up to 20V/5A.

Which USB Power Delivery voltages does it support?

The adapter supports 5V, 9V and 20V output profiles. It does not provide 12V or 15V PD output.

Will a 90W DC charger power a 90W laptop?

It may not work reliably because the input charger must provide more wattage than the receiving device requires. Use a DC charger rated above the laptop's power requirement.

Is this adapter bidirectional?

No. It converts power from a compatible DC 7909 female input to a USB-C male output; it does not convert USB-C power to DC 7909.

What comes in the package?

The package includes one DC 7.9x0.9mm female-to-USB-C male charging adapter.
