An additional Powerbank for the portable "ACD" may be required if you do not want to wait several hours for the battery in the kit to charge.
For optimal Powerbank working capacity, it is recommended to complete 3 full discharge/charge cycles. This means you need to fully discharge and then fully charge the Powerbank three times.
You can also purchase an additional battery if you have a stationary "ACD" and want to make it portable. For this, you will also need a cord from the "ACD" to the battery.
