Traveling personal cloud options?
My pixel phone has meager storage. Could I use an old phone with bountiful SD space to serve up media via Bluetooth?
Any ideas if this would work practically speaking?
Edit: Looking for a functional equivalent of on-device storage space, i.e., for offline media consumption
USB phone jack is often used for power, so it's unlikely available for OTG storage
Battery life in the server phone should be ok since it will be running in airplane mode with only Wi-Fi and/or Bluetooth, and display off mostly
Get a NAS for home, and VPN in as needed. Store all your media on the NAS, and also use it as a phone backup target.
Downside might be that this requires a good internet connection, which depending on where OP travels might not always be available.
This. Tailscale is a VPN solution for this that's free for personal use.
Thanks but looking for offline solutions
Bluetooth is probably too slow for what you want, but you could use your old phone as a Wifi hotspot and even install various server software on it via Termux.

GL.iNet's travel routers have a USB port and support plugging in a EHDD to share over the network they create.
Get MaterialFiles and turn on sftp server to share all your files via network.
Then same network whether its hotspot or home WiFi.
If you're looking for something you can carry about and use to store data on, why not just a USB-C thumb drive or external SSD?
Edit; this is intended for photographers, but you can get external SSDs that create their own WiFi network so you can transfer files wiressly to and from them: https://www.westerndigital.com/en-gb/products/portable-drives/wd-my-passport-wireless-ssd?sku=WDBAMJ2500AGY-EESN
Some travel routers have a USB socket for media.
They're usually used to make connecting to hotel Wi-Fi easier (you connect your devices to its ssid, then connect to its admin page and connect it to the wifi, or just plug it in to the lan).
Tp-link ac750, for example

That's a neat idea of using an extra phone as a file server. I've only thought of phones as consumers, not providers.
@BigMikeInAustin @Pretzilla Only thing to worry about is the battery of the phone if its being left on 24/7
I would have to find a way to keep them on without needing a battery inserted.
Maybe be more specific?
For traveling I would suggest a laptop to behave as a server but the IP address changes a lot when traveling.
I'd personally opt for something hosted at home if possible like Nextcloud and Jellyfin with static IP and port forwarding to access on the go.
Tbh though, if you just want storage on the go buying a portable 1-4TB drive that connects via USB-C is enough.
If you don't have concerns about it being private I've used one of these for similar purposes in the past. Just a little portable DLNA server. The original project stopped but there are forks or the last version of the original out there.

This seems a bit impractical. 2 phones to keep charged and manage.
Depending in your use case can't you just get some external USB storage?
Does it have support for microSD cards?
