The CoolWallet is rechargeable and it takes about 4 - 6 hours for a full charge. The standby time is around 2-3 months. However, we recommend you charge the wallet periodically (at least once a month) to ensure maximum battery performance. The battery will last more than 1 year if it is well maintained.
Even if the battery could not be recharged, CoolWallet could still function when placed in the charging set (charging).
