Where to buy in Canada
Frequently asked questions
Where can I buy the CoolWallet Pro in Canada?+
Direct from coolwallet.io with tracked shipping to Canada (~7-10 days from Taiwan). GST/HST charged at the border. Amazon.ca has intermittent stock but verify the seller is CoolBitX (the manufacturer) before ordering.
Is Bluetooth-only secure for cold storage?+
The Bluetooth connection is AES-256 encrypted end-to-end and the private key never leaves the secure element. The Bluetooth attack surface is documented and audited — same threat model as the Ledger Nano X. For Bitcoin-only maximalists who prefer air-gapped, look at the Coldcard Mk4 instead.
How long does the battery last?+
About 3 months of standby per charge in normal use. Charging is via the included cradle over USB-C. Battery replacement requires shipping back to CoolBitX — plan for that after year 3-4.
