Dell DH112257 5 V 3 A adapter

This Dell DH112257 power adapter delivers a regulated 5 volt 3 amp output at 15 watts from a 100 to 240 volt AC input. It includes nine interchangeable DC tips plus Micro USB, Mini USB and USB Type C connectors on a 150 centimetre cord. The unit is designed as a direct replacement for lost or damaged 5 volt supplies.

Suits devices needing 5 V up to 3 A

Buyers powering routers, CCTV cameras, LED strips, Raspberry Pi boards, TV boxes or similar 5 volt gear will find the included tip selection covers most barrel jack sizes. It is not for equipment that requires 9 volt, 12 volt or 24 volt output, nor for devices drawing more than 3000 milliampere. Laptop charging and high power peripherals fall outside its capability.

Plug in and select the matching tip

Installation is straightforward: choose the tip that fits the device jack, attach it to the 5.5 by 2.1 millimetre fork on the cable and plug the adapter into a mains socket. The centre positive polarity is fixed, so devices with centre negative wiring will not work. The only common issue is accidentally using a tip with the wrong inner diameter, which prevents a secure connection.

Questions about this item

Which devices can I power with the 5 V 3 A output and the nine included tips?

The adapter delivers 5 V at up to 3 A (15 W) and ships with 5.5×2.5 mm, 5.5×2.1 mm, 4.0×1.7 mm, 3.5×1.35 mm, 3.0×1.1 mm, 2.5×0.7 mm, Micro USB, Mini USB and USB-C tips for most 5 V DC devices under 3000 mA.

Will this adapter safely run my older 5 V gear that only draws 500 mA or 1 A?

Yes. The regulated supply automatically identifies the current required by the connected device and provides anything from 100 mA up to the 3 A maximum, so legacy 5 V hardware drawing 500 mA, 1 A or 2 A works without adjustment.

How do I confirm the adapter is operating correctly after plugging it in?

Connect the appropriate tip, plug the US two-pin plug into a 100–240 V 50/60 Hz outlet, and verify the target device powers on and charges normally; the adapter supplies a steady 5 V centre-positive output up to 3 A.
