You can’t overcharge a Caliburn. It is best to unplug the device when it is fully charged, especially if it is left unattended or overnight.
Although the Uwell Caliburn has built-in safety features to prevent overcharging, it can damage battery life or even lead to burning or exploding.
The Caliburn A2, for example, can be fully charged in just 35 minutes.
