I've used a Apple Magickeyboard and a small android eink tablet (in vertical orientation) for some writing and light programming in Termux/Emacs. Very portable setup and distraction-free I don't really know if an external corded keyboard would draw much more power than bluetooth one (one could argue it'd be less b/c no wireless radio). Would be a bit tricky to confirm
