“cold wallet” or “cold storage wallet” or simply “cold wallet” — emphasises the offline-storage aspect.
“cold storage” — often used generically, e.g., “I moved coins to cold storage”.
“cold device” — less common but used by some users to mean hardware wallet (offline device).
“cold-storage device” — similar to above, a device dedicated for offline.
“USB wallet” — sometimes used (especially by novices) to mean a hardware wallet shaped like a USB stick.
“trezor/ledger (etc) device” — users will refer to actual brands by device name (“I stored my BTC on my Ledger”).
“air-gapped wallet” — a more technical variant referring to a wallet completely disconnected from the internet; sometimes used interchangeably with “cold wallet”.
“self-custody hardware wallet” — more formal/enterprise phrasing, but showing up in user posts emphasising “keys I hold myself”.
