The Zoom LBC-1 is a charger for the BT-02 and BT-03, the batteries that power the Zoom Q4 and Zoom Q8 respectively. That means you can record while your spare battery is charging!
This adapter is for your compact Zoom recorder. Use the USB A plug to connect it to an AC adapter to provide it with power.
The Zoom AD-19 power supply is specifically designed for the Zoom F-Series, LiveTrak Series, TAC-8 and UAC-8.
The Zoom BT-03 battery can be used as a spare for the Zoom Q8 and gives you a few extra hours to film.
This is the Zoom ZAD-1220E. This is a 12V DC locking adapter intended for the Zoom R20 multi-track recorder. The screw-lock connector prevents the cable from coming loose and suddenly leaving you without power during recordings.
