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?
So that’s a DC power connector, but we’re going to need more info before we can give you specifics.
For starters, we need to know the polarity. Basically, the pin is going to be one side of the charge, and the sleeve around the circumference is going to be the other. Look for something to see what the polarity needs to be. The center dot is the pin, and the C shape is the outer contact.
Next, we need to know the voltage and amperage. This should be listed somewhere on the device. Most barrel connectors are 12v, but you occasionally see 5v (when they’re powered via USB) or 20v. So that 12v isn’t a 100% guaranteed thing and it’s worth double checking. For amps, you simply need something above whatever the device is listed at. Amperage is basically how much power the device actually uses, and bigger devices will draw more power (and need a bigger power supply.) If it shows that it draws 1A at 12v, then a 12v 1.5A power supply will work, but a 12v 500mA (that’s 0.5A, since each milliamp is 1/1000 of an amp) power supply will overheat.
Lastly, we’ll need to know the diameter of the barrel. These connectors are standardized sizes, but there are a lot of different sizes. . So you’ll need some way to measure the connector and see how big it is. Easier said than done.
If you’re able to figure out the first two parts, (polarity and voltage/amps) you can get a universal power supply (with the appropriate voltage and polarity, and rated for something at/above the device’s listed amperage) that comes with a variety of barrels. Then you can simply find the right size barrel via trial and error.
Looks like a barrel plug. These are very common and finding s as replacement should be easy. On the underside of the lamp there will be writing that says what the electricity requirements are. e.g. 12V—-400mA
Look up a replacement using those numbers.
If you know the lamp model number or manufacturer or anything like that you could possibly find the specs online somewhere. I think they also sell some “universal” type barrel plug power supplies that come with various sized barrel connectors.
Already great answers here about what the terminology is.
If you want my advice on what to do, I would buy a “universal AC/DC” power adapter that comes with a bunch of interchangeable barrel plug sizes and adjustable voltage. Something LIKE this: (amazon) https://a.co/d/bnlGn8I
If you set it up right, it will probably get you going again. The side benefit is that you can “guess and check” for the right barrel plugs for any you might need in the future in case anything else needs one.
If you’re in the us, Best Buy has a few different multivarrel options where you can also change the voltage from 3.3v to up to 12v depending on what voltage the lamp is. Best buy is not the only store, you can get them online as well. I just say best buy because I needed one for my li-ion charger.
Yup the universal charger I bought also has that setting. Just make sure to read the packaging on it but either of those places should have them. Just make sure to read the packaging and double check it’ll output that voltage and amperage.

Remember to check the polarity of the plug too. Some have + in the center pin, others have -
I’d never heard of this before, but without industry standardization I can see it happening.

It doesn’t say anything on the lamp but I think I can find that on the amazon listing. Thanks
Your best bet is to find a universal charger. They sell chargers with like 20 barrel tip sizes.

oh that’s cool. The lamp is 5V/1Amp. I’m thinking of of going to Micro Center first and then try Best Buy.
