Wrong forum, but where else to ask for 'ancient tech'? A friend gave me one of these old round white Airport Extreme sase stations. He doesn't know if it still works and can't test it because the power supply is missing. In my cable collection I found a suitable plug but voltage and current are too less. It needs 5.1V and 2.4A. I found several usb cell phone chargers that have 5V and 2.4A but I'm not sure if I can use them. Any tips? Can I take one with higher voltage and current? Are there maybe power supplies I can use without cutting and soldering? I can't find any in German eBay and Amazon... Thx!
