BASEUS 9V 1A AC Adapter with 8 Interchangeable DC Plugs

SKU CH-2CM4-9TJ1B

9V 1A AC adapter with eight interchangeable DC plugs covering 100mA to 1000mA devices, 5.9 ft cable and built-in protection

  • Product typeAC Adapters
  • 9 V 1 A output powers Arduino boards and 9 V devices
  • Eight interchangeable tips fit barrel connectors from 2.5 × 0.7 mm to 6.0 × 4.4 mm
  • 100–240 V 50–60 Hz input works on mains worldwide
  • Built-in short-circuit, over-current, over-voltage and over-temperature protection
  • 9 ft cable gives flexible placement for bench or project use

9 V 1 A AC adapter with eight tips

This 9 V 1 A AC adapter supplies up to 1000 mA at a positive-centre DC output. It is intended for 9 V electronics such as Arduino UNO, Mega 2560 and 1280 boards, CCTV units and similar low-power devices. The unit accepts 100-240 V 50-60 Hz mains input and includes short-circuit, over-current, over-voltage and over-temperature protection. A 5.9 ft cable provides reach to distant sockets.

Check voltage, polarity and current before use

Verify that the target device requires exactly 9 V DC with a positive-centre connector and draws no more than 1 A. The adapter will not suit equipment with a negative-tip barrel such as certain piano keyboards or effects pedals. Confirm the required plug size from the eight supplied tips: 4.0 × 1.7 mm, 4.8 × 1.7 mm, 5.5 × 1.7 mm, 6.0 × 3.0 mm, 6.0 × 4.4 mm, 3.5 × 1.35 mm, 2.5 × 0.7 mm and the LED terminal connector.

Interchangeable tips and built-in safeguards

Eight snap-on tips cover the most common barrel sizes, so one adapter replaces multiple dedicated chargers. The moulded strain relief and 5.9 ft lead reduce wear at the connector during daily bench or desktop use. Internal protection circuits disconnect the output on fault conditions, protecting both the supply and the connected device. The compact wall-mount body plugs directly into a mains socket without a separate power brick.

Questions about this item

Which plug tips come in the box and do I need to buy any cables separately?

The box includes eight interchangeable DC tips sized 4.0×1.7 mm, 4.8×1.7 mm, 5.5×1.7 mm, 6.0×3.0 mm, 6.0×4.4 mm with pin inside, 3.5×1.35 mm, 2.5×0.7 mm and an LED terminal connector. A 5.9 ft power cord is attached so no extra cable is required.

My device draws 600 mA at 9 V — is this adapter the right choice among the listed current ratings?

The adapter supplies up to 1 A and intelligently matches loads from 100 mA through 1000 mA, so a 600 mA device will operate within the supported range.

What does the 9 V 1 A rating actually deliver when I plug it into my Arduino Uno R3?

It provides a regulated 9 V centre-positive output limited to 1 A, with short-circuit, over-current, over-voltage and over-temperature protection active during use.
