--===============0937337488841335235== Content-Type: multipart/alternative; boundary="000000000000f4ffaf05fd501bd2" --000000000000f4ffaf05fd501bd2 Content-Type: text/plain; charset="UTF-8" I think with almost any legacy power adapter for a ThinkPad, just as long as it's 20V coming in it won't care how many watts in total, however the less watts the slower it can charge the battery (if at all, in which case it'll only keep the machine on). It's going to really be dependent on CPU consumption and display size what Lenovo thinks should be an appropriate amount of juice coming into the machine. I don't know if there's a ceiling limit to the max your laptop will accept (but you can still have a larger power adapter plugged in, won't cause any harm), that's something you'll have to research and test this out. I'm assuming you're in the USA, so here are some USA Amazon links. I've had really good luck with USB Type-C PD/Power Delivery trigger modules. These go by a bunch of names like decoy adapter, step down or buck converters. You can roll your own by grabbing a 20V one and solder on the barrel connector that your T530 accepts (though finding barrel connectors at 7.9x5.4mm seems hard to source)... https://www.amazon.com/s?k=type-c+trigger+20v&i=electronics&crid=2U21H2UE0NOSW&sprefix=type-c+trigger+20%2Celectronics%2C110&ref=nb_sb_noss Or you can grab one of these extremely clean looking ones with the right connector at 20V (which are a little cheaper to replace than a whole new 3rd party ThinkPad branded power adapter, and creates less waste in the long run)... https://www.amazon.com/gp/product/B08331PF5R/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1 Be sure to measure your current barrel connector and double check you're getting the right one. If you have a few USB Type-C chargers that support PD (many chargers don't support PD and simply mimic exactly how much power is provided by a standard Type-A charger), see how fast of a charge something in the range of ~40W to ~65W gets you. There's a good chance you don't need 100W, however this little adapter will support 100W without issue. If you couple this with a GaN USB Type-C PD charger and a good USB Type-C cable that supports ~40W to ~65W (not all support 100W), you'll only need to replace the connector, and you have your pick of small power bricks to go with (possibly with some extra ports)... https://www.amazon.com/s?k=usb+GaN+60W&tag=shopwithed-20&ref=nb_sb_noss I cannot say that I've specifically used this configuration to power/charge an older ThinkPad with a barrel connector, however I've used them for multiple other applications where I didn't want to lug around an extra 20V charger the size of a brick. There's also an added benefit of being able to use this adapter in a car with a Type-C ~45W charger that plugs into the 12V port. One example is a Canon Selphy photo printer running in the back of my car printing postcards while I drove cross country, plugged into a 100W Type-C charger. I've also soldered together a 12V one into one of those annoying half oval plugs that charge up an electric shaver, again for traveling and to rude the number of power bricks I was bringing with me.
