12v Laptop Power Supply
Old/Spare power supply for your laptop*
* My laptop requires 15v 5A but using a 12v supply will power the laptop but not charge it, this is fine for emergency power if the battery gets low and I haven't finished observing.
1. Cut the cable from the transformer
2. Open 12v plug
3. Strip cable, work out polarity then solder wires to connections in the 12v plug
4. Replace covers to plug and test.
END OF PROCESS
