Below are some common questions and answers regarding the Magic Power Battery (JBMP-01):

 
What devices are compatible with the Magic Power?

The Magic Power outputs 12V at a maximum of 2.0 amps. This is a very common voltage for cinema equipment. Check your device’s DC input requirements to see if it is 12V/2A compatible.

The Magic Power battery is designed specifically for use with the following Blackmagic Design cameras and accessories:

•   Blackmagic Cinema Camera 2.5k
•   Blackmagic Pocket Cinema Camera
•   Blackmagic Production Camera 4k
•   Blackmagic Micro Studio Camera 4k
•   Blackmagic Micro Cinema Camera
•   Blackmagic Video Assist
•   Blackmagic Video Assist 4k

 

What cables do I need to connect the Magic Power to my camera or monitor?

The Magic Power comes with all cables necessary to connect the Magic Power to your compatible Blackmagic camera or Video Assist. Included with the Magic Power are two DC power cables, one cable that fits the Blackmagic Pocket Cinema Camera and one cable that fits all other compatible Blackmagic cameras and monitors.

 

How long will the Magic Power battery power my camera?

The longevity of the Magic Power battery varies some depending on camera settings and powered lens use. Shooting in RAW format with an autofocus lens, the Magic Power will last approximately 3.5 hours with the Blackmagic Cinema and Production Cameras, and will last approximately 7-8 hours with the Blackmagic Pocket and Micro Cameras.

 

Can I power multiple devices with the Magic Power at the same time?

The Magic Power is capable of outputting up to 2.0 amps continuously and can run most compatible cameras and field monitors in combination. As long as the total power draw does not exceed 2.0 amps, the Magic Power is capable of powering multiple devices simultaneously.

In order to simultaneously connect two devices with DC inputs to the Magic Power, Juicebox offers a DC splitter cable. You can view the product page for the Juicebox DC Splitter Cable, the JBSC-01, here: http://juicebox.direct/product/jbsc-01/

 

How long does the Magic Power battery take to charge? Does the light turn green when it reaches full charge?

Because the Magic Power battery typically comes fully drained of power, the first charge of the battery can take much longer than subsequent charges. Although the initial charge can take up to 5 hours, with even semi-regular use, charging the battery should only take 3-4 hours after the initial charge. When the battery is fully charged, the LED indicator light will turn from red to green.

NOTE: In order to charge the Magic Power battery, the battery switch must be in the “ON” position and the charger plugged into the “IN” port at the front of the battery.

 

How should I mount the Magic Power Battery to my camera?

Because every camera rig is different, the Magic Power battery was designed with the intent of allowing limitless mounting configurations. The Magic Power battery is fitted to a mounting plate with multiple standard (1/4-20) and over-sized standard (3/8″) threaded mounting holes, enabling the user to connect the battery to their rig at different points, depending on need. The Magic Power battery also includes a 1/4-20 mounting screw, enabling the user to mount the battery directly to the camera or camera cage.

However, some users find this setup to be cumbersome, especially when mounting the battery directly to the camera gets in the way of other accessories.

Our recommendation for mounting accessories varies depending on the way in which you use your camera. For rail rod setups, we recommend a 1/4-20 rail clamp (such as this one: https://amzn.com/B006TAO7CM). These are inexpensive and available at most photo and film equipment retailers.

For tripod or monopod use without a rail rod system, or use on a gimbal or other stabilizer, we recommend an adjustable 1/4-20 clamp (such as this one: https://amzn.com/B00E5M39AW ). This will allow for the battery to be quickly connected directly to a stabilizer and easily rearranged during a shoot.

For handheld shooting, we recommend connecting the Magic Power battery directly to the camera or camera cage using the included 1/4-20 mounting screw and nylon washer.
