Dell NOACDC51000 5V 1A adapter
This Dell NOACDC51000 adapter delivers 5 V at 1 A through a 5.5 x 2.5 / 2.1 mm DC barrel plug. It accepts 110-240 V AC input at 50/60 Hz for worldwide mains compatibility. The 4.9 ft output cable reaches distant sockets without strain. The unit weighs 68 grams and comes in black plastic housing.
Installation and common issues
Plug the AC side into a wall outlet and the DC barrel into the device; the spring-loaded centre pin fits both 2.5 mm and 2.1 mm inner diameters. Polarity is centre-positive, so verify the device label before connecting. A mismatched barrel size will prevent power delivery entirely. No driver or configuration is required.
Who this suits and who should look elsewhere
Ideal for owners of routers, hubs, monitors or audio gear that specify a 5 V 1 A supply with a 5.5 x 2.5 / 2.1 mm centre-positive jack. Buyers whose equipment needs higher voltage, more current, a different barrel size or reverse polarity cannot use this adapter.

Questions about this item
How can I verify the adapter is delivering the correct 5V output after plugging it in?
Use a multimeter set to DC volts and measure the centre pin of the 5.5x2.5 / 2.1mm plug; it should read 5V±0.3V under load.
What is included in the package and is there anything else I need to buy?
The box contains one AC-DC 5V 1A 1000mA adapter with a 4.9ft DC output cable; no extra cables or accessories are required.
Which version of this adapter should I choose for a device that needs a 5.5x2.5mm or 2.1mm centre-positive barrel jack?
This single model NOACDC51000 fits both 2.5mm and 2.1mm inner-pin sizes thanks to its internal spring plate, so no other version is needed.
