Product Identity

This JacobsParts ADP-5V-B is a 5 V 4 A AC/DC adapter rated at 20 W maximum output. It terminates in a 3.5 x 1.35 mm male barrel connector and accepts 100-240 V input for worldwide use. The unit is finished in black and weighs 0.18 kg.

Fit and Alternatives

It suits owners of USB hubs or similar devices that require exactly 5 V through the small 3.5 mm barrel jack. Users whose equipment demands a different voltage, a higher current, or a larger 5.5 mm barrel connector will need another power supply.

Decisive Specification

The 3.5 x 1.35 mm male barrel connector is the critical detail; it only fits jacks of that exact diameter and pin size. Verify the device jack before ordering, as an incorrect barrel dimension will prevent connection.

Questions about this item

Does this adapter need a separate mains lead or does it plug straight into the wall?

The unit has a built-in AC plug that accepts 100-240 V, so no separate mains lead is required.

Will the 3.5 x 1.35 mm barrel fit the power port on my existing USB hub?

The connector is a male 3.5 mm outer by 1.35 mm inner barrel; match those dimensions against your hub's jack before connecting.

How can I confirm the adapter is delivering the rated 5 V 4 A after I plug it in?

Measure the output with a multimeter set to DC volts while the hub is running; you should see a steady 5 V under load.
