Adapter cable extra digital USB Type-C to DC 4.8×1.7 mm - power supply adapter

USB Type-C to DC 4.8x1.7 mm adapter converts a USB Type-C PD power source into a standard 4.8x1.7 mm DC plug suitable for laptops and other devices with matching sockets. The adapter connects a USB Type-C charger or power bank to devices that require a 4.8x1.7 mm DC connector and supports USB Power Delivery for higher power delivery when used with compatible chargers and cables.

Advantages

The adapter provides a compact and simple way to power devices with a 4.8x1.7 mm DC input from a USB Type-C PD charger. It supports up to 100 W (19.5 V / 5 A) when the connected charger and cable allow, enabling use with many laptops and higher-power devices. The plug fits standard 4.8x1.7 mm DC ports without a center pin and requires no additional configuration.

Suitable for

• Powering laptops and notebooks with a 4.8x1.7 mm DC input
• Using USB Type-C PD chargers or power banks to feed older devices
• Field work or travel where carrying a single USB Type-C charger is preferable

When it may not be suitable

The adapter only provides the voltage and current negotiated via USB Power Delivery; if the connected USB Type-C charger or cable cannot supply the required power, the device may not charge or may charge slowly. It is not a universal solution for devices that require a proprietary center-pin signaling or non-standard voltages outside the USB PD range.

Key specifications

• Connector A: USB Type-C (female)
• Connector B: DC 4.8 x 1.7 mm (male)
• Maximum output power: up to 100 W
• Nominal voltage: 19.5 V (when negotiated via USB PD)
• Maximum current: up to 5 A
• Standard: USB Type-C Power Delivery (PD)

How to use

Plug the USB Type-C end into a compatible USB PD charger or power bank, then insert the 4.8x1.7 mm DC plug into the device’s DC input. Ensure the charger and cable support the required power level; the device and charger will negotiate voltage and current via USB Power Delivery automatically. Disconnect the adapter when not in use.

What to consider before purchase

• Confirm your device uses a 4.8x1.7 mm DC jack without a center pin
• Check that your USB Type-C charger and cable support USB Power Delivery and the required wattage
• Verify the device’s required voltage and current are within the adapter’s supported range

Usage recommendations

For reliable charging, use a USB Type-C PD charger and a high-quality USB-C cable rated for the required current. Avoid using the adapter with devices that require proprietary signaling via a center pin or voltages not supported by USB PD.
