1.2 m DC power cable for HP and Dell laptops

This 1.2 metre cable carries a 7.4 mm by 5.0 mm DC barrel connector suited to compatible HP and Dell notebook power adapters. It replaces a lost or damaged lead so the original charger can stay in use. The cord is supplied new and ready for daily connection between the mains adapter and the laptop input.

Thermals noise and power draw in normal use

The passive cable generates no noise and adds no active heat beyond the normal resistance of its conductors. Power delivery is limited by the connected adapter and the laptop's own charging circuit, so the cord itself does not alter the system's thermal profile or power consumption.

Questions about this item

How do I install the 7.4 x 5.0 mm DC jack on my laptop charger?

Align the 7.4 x 5.0 mm barrel plug with the laptop power port and push straight in until it seats firmly; the step people miss is forcing it at an angle, which bends the centre pin.

When should I replace this 1.2 m power cord?

Replace the cord if the insulation frays near the DC jack or the plug feels loose in the 7.4 x 5.0 mm port, as intermittent contact can damage the laptop charging circuit.
