Please note the Coldcard does NOT have an integrated battery - for security and durability reasons. To operate the device you will need an external power source - such as a USB-C cable. If you would like a USB-C cable to be included - please add it as an optional extra. We also recommend adding a Micro-SD - for future firmware upgrades and as part of a good air-gapped security setup.
