Where can i get guidance - how and when to use the knob/dial. where can i manual be supplied, some sort of guidance thanks

Do not recall if unit comes with a manual, but do not think so. Extremely easy to use if you know anything about electronics. You have to know what voltage you are trying to supply and just rotate dial to that voltage. Plenty of connection adapters included. You also need to know if center conductor is + or - if you do not understand my directions, this or any other variable adapter power supply is not for you.

It works for dc4.8v _ 250ma

Hi,our ALITOVE 30W Universal AC to DC Power Supply Adapter output voltage can only adjust by 4.5V 5V 6V 7.5V 9V 12V. If your device working voltage isn't powerful than 5V,our 30W power supply adapter might work. Any unclear plz contact me.

would this work to charge a 3d pen? i need an ac dc adapter

Check your 3d pen working voltage and max current,below is our 30W power supply adapter parameter. Input: AC 100V~240V, 0.25A, 50/60Hz Output Voltage: DC 3V / 4.5V / 5V / 6V / 7.5V / 9V / 12V Adjustable Output Current: Max 2.5A Output Wattage:Max 30W DC Plug Size: 5.5x2.5mm; 5.0x2.1mm; 4.0x1.7mm; 3.5x1.35mm; 3.0x1.1mm; 2.5x0.7mm

So I get it, trying to get hits with all sear4ches. ? is....what is the output amps? I need minimum 1.5A

The only output it shows is for the USB port and it shows 5v @ 2.1A So I would think it should put out 2.1A on the cord as well A crossed whatever voltage you sell it to from the 3v up to 12v
