I'm in Myanmar right now, doing some charity work :) But I also have to teach online for several hours each evening. Having been a teacher in this country for many years I'm aware of some of the problems of unreliable internet and unreliable mains electricity, but things are a lot worse now!

I'm using an Asus TUF A15 laptop to teach online, which is 'overkill'. Although I've applied recommended 'tweaks' to reduce the energy consumption, with the mains power off for about 18 hours/day, I'm having to use car batteries and an inverter to keep my laptop going :) I need a laptop with a much lower energy consumption/longer battery life.

I can't do much about the unreliable internet, but it would be nice to have a low-power laptop that has a built-in LTE/4g SIM card support. Mobile internet is more reliable than hotel wi-fi, and it would be nice (but not an absolute need), if I can avoid USB/ethernet tethering etc.

This laptop will be my Zoom lesson laptop, so it simply needs to be able to handle Zoom video lessons and shared screen (2 students max) for me to play YT videos etc during the lesson.

Any recommendations? Or questions? Thanks for your advice.
