FAQ Section

Can I use this 5A adapter for a device that only requires 2A?Yes, absolutely. A device will only draw the current (Amps) it needs. As long as you set the voltage (V) correctly using the dial, the 5A capacity simply means the adapter won't overheat while powering your 2A device.
Will this work for my 12V LED light strip?Yes. Simply turn the rotary dial until the LED display reads exactly 12.0V before connecting your LED strip. It provides stable, flicker-free power.
Does it remember the voltage setting if I unplug it?The voltage is determined by the physical position of the rotary dial. When you plug it back in, it will output the voltage corresponding to where the dial was last set. We recommend checking the LED display before connecting your device.
