Two black rectangular wall adapters with detachable barrel tips and thin cables

BASEUS

BASEUS 2-Pack 12V 1A AC Adapter 5.5x2.5mm & 5.5x2.1mm

SKU CH-5ATR-G4N00

Two 12 V 1 A adapters with 5.5 × 2.5 mm and 5.5 × 2.1 mm tips, 100–240 V input, 89 cm cable and UL-listed protection

  • TypeAC Adapters
  • Dual plug tips fit 5.5x2.5mm and 5.5x2.1mm sockets
  • Global 100-240V input works at 50 or 60Hz worldwide
  • UL certified protection guards against over-voltage, over-current and over-temperature
  • 89cm cable gives 2.92 feet of reach for flexible placement
  • 12W regulated output delivers stable 12V 1A power for low-draw devices

Two-pack 12 V AC adapters with dual plug sizes

This pack contains two regulated switching power supplies that convert 100-240 V AC at 50/60 Hz into 12 V DC at 1 A. Each unit delivers up to 12 W and includes an 89 cm (2.92 feet) cable. The adapters suit low-power devices such as routers, LED strips, CCTV cameras or small audio gear that require a 12 V centre-positive supply.

Plug-and-play with two interchangeable tips

Each adapter terminates in a 5.5 mm outer-diameter barrel fitted with a 2.5 mm centre pin; the spring-contact design also accepts 5.5 x 2.1 mm sockets without tools. Installation is simply matching the tip to the device jack and plugging into mains power. The only common issue is connecting equipment that draws more than 1 A or requires centre-negative polarity, which will cause the unit to shut down or risk damage.

Limited to 12 W at 12 V with fixed cable length

The 12 V 1 A rating caps usable power at 12 W, so any device needing higher current or voltage cannot be powered. The 89 cm cable fixes the reach between the wall outlet and the device; extensions add resistance and are not recommended. The wide 100-240 V input covers global mains standards, but the adapter cannot supply adjustable voltages or currents beyond its single fixed output.

Questions about this item

How can I confirm the 12V 1A adapter is working after plugging it in?

The regulated switching converter delivers 12V at up to 1A; the connected device should power on and operate normally without overheating.

What plug sizes are included with the two adapters?

Each unit terminates in a 5.5x2.5mm DC plug that also fits 5.5x2.1mm sockets thanks to the centre spring contact.

Which of the two supplied tips should I use for my 5.5x2.1mm device?

The same 5.5x2.5mm tip fits both sizes because the inner spring contact accommodates the 2.1mm centre pin.
