Thank you for your suggestion. I found an old Android tablet. I used ForceDoze app using Shizuku (temp root) to prolong battery life for 3 days for using 3 hour daily. And using Moonreader + for my books with reading mode and put on a hazy screen protector. It works wonderfully now. Setup was a bit of hassle. But now it’s done.
