Connector conversion for laptop power

This adapter bridges a 4.8 x 1.7mm male plug to a 5.5 x 2.1mm female socket so a laptop charger with the larger barrel can power a device that requires the smaller tip. It is a passive gender changer built for notebook users who need to match two different barrel standards without replacing the original power supply.

Behaviour under continuous use

The short 10cm cable keeps resistance low and prevents voltage drop during sustained charging sessions. Because the assembly is small and lightweight it adds negligible strain to the laptop port, reducing the risk of intermittent contact when the notebook is moved while plugged in.

Deciding specification: 4.8 x 1.7mm male to 5.5 x

Only devices that accept a 4.8 x 1.7mm input and power bricks fitted with a 5.5 x 2.1mm output will work with this adapter. Buyers whose equipment uses any other barrel diameter or pin size cannot use this part and must seek a different connector combination.

Questions about this item

How much power does the 4.8 x 1.7mm male plug draw when the adapter is used all day?

The adapter is a passive cable with no active electronics, so it draws no power itself; only the connected laptop power supply determines consumption.

What must I already own for the 5.5 x 2.1mm female jack to work with my laptop?

You need a laptop or power supply that provides a 4.8 x 1.7mm male output, because the adapter converts that specific barrel size to the larger 5.5 x 2.1mm female connector.

Will the 10 cm cable length reach a legacy 5.5 x 2.1mm charger sitting on the floor from a desk-mounted laptop port?

At 10 cm the cable is very short, so the legacy charger must sit right next to the laptop; it will not stretch from desk to floor.
