Before you choose

Consider

Coinkite COLDCARD Mk5Needs USB-C power during use. Check the current seed-generation advisory before reusing an older wallet; updating alone does not repair an affected seed.

BitBox02 NovaOn iPhone and iPad, Bluetooth carries the data but the wallet still needs a physical power connection. You control it by touching its edges, not the screen. BitBoxApp on iPhone and iPad guides firmware updates when a compatible version is offered.
