Universal 5 V 2 A adapter

This 10 W Dell power supply delivers a regulated 5 V output at up to 2 A from any 100–240 V AC mains. It ships with eight interchangeable DC tips including Micro-USB, USB-C, terminal block and barrel sizes from 2.5 mm to 5.5 mm, covering a wide range of low-voltage devices. Indoor use only, with centre-positive polarity on every tip.

Build integration

The unit plugs directly into a wall socket and requires no extra cabling beyond the chosen tip. Its compact corded design frees up bench space and eliminates the need for multiple dedicated wall-warts when powering routers, cameras, LED strips or development boards. The fixed 1.5 A and 1 A compatibility means it can safely supply lower-current gear without adjustment.

Capacity limits

At 10 W maximum the adapter comfortably runs single 5 V loads such as security cameras, USB hubs or small fans. It cannot support devices that draw more than 2 A or require voltages above 5 V, so multi-bay drive enclosures, higher-power LED arrays or 12 V equipment are outside its operating envelope.

Questions about this item

At what output current does this adapter hit its 10 W limit under sustained load?

The adapter reaches its 10 W ceiling at the rated 2 A maximum output current, which is the highest sustained load it can deliver.

How warm does the unit get and how much noise does it make when running continuously at full load?

The supply has no fan and no moving parts, so it runs silently; the case warms to normal operating temperature within the rated -20 °C to 50 °C range.

Which DC tip from the included set must I already have fitted to match my device's jack?

The kit supplies eight tips — 5.5×2.5 mm, 4.0×1.7 mm, 3.5×1.35 mm, 3.0×1.1 mm, 2.5×0.7 mm, Micro-USB, USB-C and a terminal connector — so you select the one that matches your device's socket.
