Powerbook 180 ac adapter
Posted by: macman0512 on 2021-10-12 11:29:00 Hi guys, I just bought a powerbook 180 but it came without a charger. Since an original is either super expensive or expensive to ship where I live, and a Sony Psone brick which has the right specs(7,5 Volts, 2 amps, right polarity) isn't, I was wondering if anyone has any experience using it. The only thing I couldn't figure out is if the barrel size is the same.

Posted by: sutekh on 2021-10-18 16:02:21 I had a post about this I thought, but looks like it was lost in the purge 🤷‍♂️ Any of the cheaply available 5.5mm x 2.1mm solder-on connectors (or an adapter if you prefer) should serve nicely.
