The trick of retrofitting any battery powered device into a wired one is to remove the battery. No matter what, Li-ion batteries cannot sustain permanent power. Expensive adapters and new Androids can regulate power well, as can automations, but the best worry-free option is battery removal.

Edit: I’ve just remembered Fairphone, they’re bossing the mobile repair ability front and have removable batteries like pre-2012. Could get one of those

I got one recently by B&H Photo Video, may have got lucky but the drive was brand new and untampered, and was in plastic cushioning, in a fitted box, inside 6" of airbags, inside another box. Delivered by DHL Express.

Sometimes DuckDNS goes down partially, their servers breaking for about a week is why I purchased a domain and now host via Cloudflare.

Edit: One of my DuckDNS domains works internally, so at least it’s not a systemwide issue. Perhaps one of their relays…
