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?
Is there any brand and/or sticker (or embossed voltage information) on this lamp? Anything to ident it? Because i've found similar ones, but they're modernized, using USB ports rather than the old barrel plug. The information found on that sticker or any information, really is more valuable than the picture, because we can probably guess exactly what you need to buy down to the voltage.
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.
