Power adapter plug connector ALIGATOR CONT008 USB-C to 7.4 x 5.0 mm for Dell laptops

ALIGATOR CONT008 is a USB-C to 7.4 x 5.0 mm power adapter plug designed to connect modern USB-C chargers to Dell laptops that use the round 7.4 x 5.0 mm barrel jack. The adapter provides a simple mechanical and electrical conversion so that USB-C power sources can deliver power to compatible Dell notebook models. It is intended as a replacement tip, an adapter for travel, or a quick repair accessory when an original barrel connector is lost or damaged.

Advantages

The adapter offers a compact and lightweight solution that enables USB-C chargers to supply power through a 7.4 x 5.0 mm Dell-style barrel connector. Its construction ensures correct polarity and a stable mechanical fit with Dell laptop inlet sockets of the matching size. The small form factor makes it convenient to carry as a spare part, while the direct conversion avoids the need for a full replacement power brick.

Suitable for

• Replacing a lost or damaged 7.4 x 5.0 mm Dell barrel tip
• Using a USB-C charger to power older Dell laptops with a 7.4 x 5.0 mm input
• Travel and emergency charging when carrying a single USB-C charger
• Service and repair workshops that adapt chargers for testing and diagnostics

Key specifications

• Input interface: USB-C plug (power delivery capable when used with PD charger)
• Output connector: cylindrical barrel 7.4 x 5.0 mm (compatible with Dell laptops using this size)
• Function: DC power conversion from USB-C to barrel connector
• Physical: compact, lightweight adapter tip for direct insertion into laptop power inlet
• Compatible use: designed for laptops requiring the 7.4 x 5.0 mm barrel connector and appropriate DC voltage/current from a USB-C PD source

How to use

Connect the ALIGATOR CONT008 adapter to a suitable USB-C power source, preferably a charger that supports USB Power Delivery and provides the voltage and current required by the target Dell laptop. Insert the 7.4 x 5.0 mm barrel end into the laptop’s power input securely. Verify that the laptop indicates charging or power presence. If the laptop does not power on, check the charger's PD profile, cable quality, and verify the laptop's required voltage and current specifications before further troubleshooting.

Usage recommendations

Use a USB-C charger that supports Power Delivery and can supply the proper voltage and current for the specific Dell model. Avoid forcing the barrel connector if it does not fit smoothly; confirm size compatibility and inspect the laptop inlet for damage. This adapter converts the connector type but does not change or boost voltage—ensure the power source matches device requirements to prevent malfunction.
