BONAEVER 12W Multi-Voltage AC/DC Adapter 3V-12V 1A Micro USB

SKU CH-KHAX-AV9Q3

Adjustable 3 V to 12 V output up to 1 A with eight swappable tips for low-power household devices

  • Adjustable 3 V–12 V output powers many household devices
  • Eight interchangeable tips fit a wide range of electronics
  • 100–240 V AC input works worldwide at 50/60 Hz
  • Centre-positive polarity matches most DC-powered equipment
  • 12 W maximum rating supports loads up to 1 A

Adjustable Universal AC/DC Adapter

This BONAEVER adapter supplies selectable DC output at 3 V, 4.5 V, 5 V, 6 V, 7.5 V, 9 V or 12 V with a maximum current of 1000 mA. It accepts AC input from 100 V to 240 V at 50 Hz or 60 Hz. The unit includes eight interchangeable DC plugs, a switch key and a manual. Polarity is fixed centre positive. It is intended for household electronics rated up to 12 W.

Suitable for low-power devices needing a specific

The adapter suits owners of routers, audio gear, toys or similar equipment that require one of the listed voltages and draw no more than 1 A. Buyers whose devices need a higher current, a voltage outside the 3 V to 12 V range, or centre-negative polarity should look at something else. The fixed centre-positive tip cannot be reversed.

Maximum output current of 1000 mA

The single specification that decides compatibility is the 1000 mA current limit. Any device drawing more than 1 A at the chosen voltage will overload the adapter. Match the required voltage exactly using the manual selector and confirm the device uses centre-positive polarity before connecting.

Questions about this item

How do I set the correct voltage and choose the right tip for my device?

Use the switch key to select 3, 4.5, 5, 6, 7.5, 9 or 12 volts, then pick the tip from the 8-piece kit that fits your device jack.

What parts might wear out and need replacing after extended use?

The DC tips can loosen or bend, the switch key may stiffen, and the cable insulation can fatigue at the strain relief over time.

What limit will I hit first if I run this adapter continuously at full load?

The 12 watt ceiling means output current cannot exceed 1000 mA at any selected voltage, so sustained draw above that trips the protection.
