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 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!
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.
