I know it’s the old round pin we used for phones back in the day but can someone send me a link to the exact one because I’m seeing too many round pin charges of different sizes. Also where do I go for tech help related questions like these? Is this the right community?
Yeah! the other end of the barrel plug is a usb port. I found the amazon listingof my lamp and it is 5V/1A, 3Watts but the diameter of the barrel plug is not mentioned in the description.
