I’ve been into typewriters for a while which is a good way to write distraction free, but also have gotten into older word processing devices and electronics.
Alphasmart devices and Palm PDAs are great ways to write distraction free but also with some of the convenience of word processing.
I love my Pinecil V2. It was cheaper than my 40W entry level Weller station and heats up way faster. I run it off my Anker USB power supply and also my Anker USB power bank. The power bank only outputs 30 or 40 watts though so I might upgrade that in the future. High wattage power banks are expensive though :/
