240W Power Adapter for IBM

This DC converter plug connects a 7.9 x 5.5mm male source to a 5.5mm x 2.5mm female device. It supports up to 240W of power delivery for compatible hardware. The plug-and-play design requires no drivers or configuration. It is built for straightforward power conversion tasks.

Suits IBM users with mismatched barrels

Ideal for owners of IBM equipment needing to bridge the specific 7.9mm to 5.5mm barrel size difference. Not suitable for devices requiring a different outer or inner diameter combination. Buyers needing voltage regulation or step-down conversion should look elsewhere. This is a passive physical adapter only.

Handles 240W continuous load

Comfortably powers laptops, monitors or peripherals drawing within the 240W rating through the 5.5mm x 2.5mm tip. Headroom exists for typical peak draws below this limit. It runs out when connected hardware exceeds the rated wattage or demands a different connector polarity. The fixed cable ends offer no length adjustment.

Questions about this item

What size power supply plug must I already have to use the 7.9 x 5.5mm male end?

Your power supply needs a 7.9mm outer diameter and 5.5mm inner diameter jack for the male connector to fit.

Will this adapter let me keep my existing 5.5 x 2.5mm barrel cable when switching to the larger 7.9 x 5.5mm port?

Yes, the 5.5 x 2.5mm female side accepts your current cable while the 7.9 x 5.5mm male plugs into the new port.

How can I confirm the 240W rating is being delivered after I connect everything?

The adapter is passive; verify the connected device powers on and runs stably under its normal load.
