Universal 30W Adapter with Adjustable Voltage

This 30W universal AC adapter accepts 100-240V input at 50-60Hz and delivers adjustable DC output from 3V to 12V at up to 2.5A. Fourteen interchangeable tips cover barrel sizes from 2.5 x 0.7 mm to 6.5 x 4.4 mm plus Micro-USB, Type-C and a DC terminal connector. A built-in 5V 2.1A USB port adds direct charging for phones or power banks. FCC CE ROHS certified with overload over-voltage overheat and short-circuit protection.

Verify Device Voltage Polarity and Connector Fit

Confirm the target device operates between 3V and 12V and draws no more than 2.5A. Match the required barrel-plug dimensions or USB interface to one of the 14 supplied tips. Ensure the polarity of the chosen tip matches the device socket before connecting. The USB port supplies 5V 2.1A only; it does not support the adjustable voltage range.

Powers Multiple Low-Voltage Gear from One Mains

The adapter replaces several dedicated bricks for tablets scales routers speakers CCTV cameras and similar 3V-12V equipment. The 4.9FT cord reaches distant outlets while the voltage knob adjusts by hand without extra tools. Built-in smart IC shuts the unit down on fault conditions protecting connected hardware. USB cable for the 5V port is not included.

Questions about this item

Does the 30W universal AC adapter include the 14 interchangeable tips and USB cable in the box?

The adapter comes with 14 interchangeable DC tips covering sizes such as 5.5 x 2.1 mm, 5.5 x 2.5 mm, 3.5 x 1.35 mm, Micro-USB, Type-C and a DC terminal connector; a USB cable is not included.

Which adjustable voltage setting should I select for a device rated at 9V 2A?

Turn the voltage knob to the 9V position; the adapter can deliver up to 2.5A at that setting, so a 2A load is within its capability.

What does the 30W rating mean when the adapter is powering a 12V laptop?

At 12V the maximum current is 2.5A, giving 30W of available power; the built-in smart IC will shut the unit down if the load exceeds that limit.
