Batteries & Power Accessories

Relay Camera Couplers work in tandem with the Case Relay Camera Power System to keep your camera powered continually with an external 5V USB battery pack or wall power. The Relay Coupler is simply an insert for your camera battery cavity that enables powering the camera via Case Relay Camera Power System. The coupler does not contain a battery or hold a charge.

Two batteries are better than one, but only if they are charged and ready for action. The ProMaster Dually Charger can charge two batteries simultaneously, or just 1 if required. It is compact and convenient with a USB-A input cable that neatly stores itself in the bottom of the charger.

Since it draws power from USB sources, you can use the Dually Charger with a USB AC Adapter (not included), laptop, power bank, car charger, and more.
