What this adapter replaces

The JacobsParts JP-22-D1 is a 22 W AC adapter that delivers 9.5 V at 2.3 A through a 5.5 x 2.5 mm centre-positive barrel plug. It suits devices that specify exactly that voltage and connector size.

Build and daily use

The unit accepts 100 to 240 V AC input for worldwide mains compatibility and ships with a detachable power cord. A round cable and compact brick keep desk routing simple and the package includes both the adapter and the cord.

Check before ordering

Verify that your equipment requires 9.5 V DC with a maximum draw of 2.3 A and uses a 5.5 mm outer by 2.5 mm inner barrel jack wired centre positive. Devices needing a different voltage, higher current or another connector type will not work with this supply.

Questions about this item

What voltage and current does the 5.5x2.5mm barrel connector deliver?

The adapter provides a regulated 9.5 V at up to 2.3 A, giving a maximum of 22 W through the center-positive barrel plug.

What are the physical dimensions and weight of the unit?

The power brick measures 5 x 6 x 1 inches and weighs 7.7 ounces, with a round cable and a standard IEC inlet for the included mains cord.

How do I connect it correctly and what is the common mistake?

Plug the IEC cord into the adapter, then insert the 5.5 mm barrel into the device; the frequent error is reversing polarity — this unit is center positive, so verify the device symbol matches before powering on.
