Starting from the Google Pixel 8 the following solution should work with Android 17 and an USB-c to HDMI adapter:
Android is the most used operating system in the world, commanding roughly 73% of the global mobile operating system market as of early 2026. Powered by the Linux kernel and developed by Google, it boasts an active global base of over 3 billion devices.
As demonstrated in the example the Google Pixel Pro is very powerful smartphone, which has a long battery life.
To use it as laptop, we need a keyboard and a mouse as well as a HDMI monitor. I bought a 13 HDMI display from Aliexpress which was about 120 USD, which is touchable and excellent with the colors.
Now we need additionally a power bank. It needs some testing how big the battery has to be. But there are very powerful power banks available from Digitec in Switzerland for about 130 USD.
It is a quiet big device. May a smaller power bank is sufficient. I stopped buying laptops, since they always broke. But I still miss a mobile device for certain applications. With the setup here I have a setup which is built from single components, which are not very expensive. And the single components can easily be replaced.
