Using 5 meter power extension to charged up laptop during class

This is taken last 9 December 2024. Where I used my power extension that have 5 meter cord length to charged up my laptop. 

This is during 2 hours class of microprocessor subject. Need to use laptop to take notes and check up notes during class in session. Now already started programming session. So, it is best to try simulate the code for faster verification during class in session.

Until then, have fun in using suitable cord length to your power extension for your usage.
