90 W 19 V adapter for audio gear

This 90 W power supply delivers 19 V at 4.74 A to amplifiers, DACs, laptops and other 19 V devices. It ships new with UL, FCC, CE and RoHS certifications and a pure-copper output cord. The barrel connector fits 2.1 to 2.5 mm sockets.

100-240 V input with 50/60 Hz tolerance

The unit accepts AC mains from 100 V to 240 V at either 50 Hz or 60 Hz, so it works on household power worldwide without a voltage selector. Built-in overload, over-voltage, thermal and short-circuit protection plus a fuse cut power automatically during a fault. Maximum continuous output is limited to the rated 90 W.

Replaces lost or under-rated 19 V bricks

It replaces a missing or lower-current 19 V adapter for compatible audio amplifiers, laptops, LED strips, routers, hubs, switches or security cameras. The jump is worthwhile when the original supply cannot deliver 4.74 A or lacks safety certifications. Not for devices that require a different voltage or a higher current than 4.74 A.

Questions about this item

Which voltage and current rating should I match for my amplifier or laptop?

Choose the 19V 4.74A version; it delivers 90W and fits devices that specify 19V 4.74A input.

What does the 90W rating mean when the adapter is powering my DAC or laptop?

It means the unit can continuously supply up to 90 watts, so a 19V 4.74A load will run without voltage sag or thermal shutdown.

What plug standard does the 2.1–2.5mm socket follow, and what current does it cap at?

The barrel connector accepts 2.1mm to 2.5mm centre pins and is rated for the full 4.74A output.
