Get yourself the Pinecil V2. It’s cheap, open software and open hardware, works with USB-C so you can power it with a power bank with Quick Charge or Power Delivery, and it works beautifully. The tips are admittedly not cheap, but they’re great because the ceramic element is welded to the metal so the heat is transferred quick and efficiently. Oh, and they sell the spare parts. AFAIK you can get it directly at Pine64’s website, but probably also on Ali.
