Replacement adapter for Radio Shack 273-1690

This NShi AC adapter replaces the Radio Shack catalog number 273-1690. It delivers 18 VAC or 24 VAC at 1000 mA through a 5.5 mm barrel plug. The unit suits owners of legacy Radio Shack equipment needing a direct substitute.

Verify voltage and connector before ordering

Confirm the device you intend to power accepts 18 VAC or 24 VAC and uses a 5.5 mm outer-diameter barrel jack. Select the correct voltage setting on the adapter to avoid damaging equipment that lacks internal protection. Check the charging port for debris that could prevent proper contact.

Fits legacy Radio Shack devices with barrel input

The adapter plugs straight into hardware designed for the original 2731690 supply. Built-in over-current, over-voltage and short-circuit protection helps safeguard connected gear. No additional cables or converters are required when the target device matches the voltage and 5.5 mm tip specification.

Questions about this item

Does the package include anything besides the adapter itself?

The box contains only the 18VAC power adapter with its 5.5 mm barrel plug; no extra cables, tips or mounting hardware are included.

Should I select the 18 V or 24 V setting for a device that originally used the Radio Shack 273-1690 supply?

Match the voltage printed on the original equipment; the adapter can deliver either 18 V or 24 V AC, so set it to the value your device requires before plugging it in.

What does the 1000 mA rating mean when the adapter is powering my equipment?

It means the unit can supply up to 1 A of alternating current at the chosen voltage; your device must draw 1 A or less to operate within the adapter’s rated capacity.
