The A1504 uses smart dynamic power allocation. When you connect or disconnect a device, the charging station redistributes power across its charging outputs. During this process, charging may pause for about one second while the device renegotiates power. Charging then resumes automatically without damaging the battery.

Tip: If you need uninterrupted charging, such as when using a laptop to transfer data, connect all your devices before starting or avoid connecting and disconnecting devices during use.
