In the world of professional video photography, portability can be a big issue. Even if you’re shooting video on a small set, you’re still going to need to get around that set, and you’re going to need power to your camera as you’re maneuvering your way around. There are a variety of power options available to you, and you may want to utilize a mix of them to ensure that you have a specific power solution for your specific power needs. Your space may be limited, as well as your access to a power outlet, but that doesn’t mean that your video power supplies need to be limited, too.
The first and most obvious of video power supplies is a direct link to an outlet. There are many cables and power supplies that allow you to move around the studio. You can get power cables in a variety of lengths to suit your needs. Various AC adaptors will transform the current from AC to DC, if your camera runs off of a direct current. Four pin XLR cables are a common connection for mid-higher cameras. And long cables will enable you to move around the studio without having to find a new outlet to plug into every time to change positions. Be aware that as distance is increased, voltage can drop and amperage increase; it’s best to consult the power supply’s manufacturer for optimum performance limits.
You can also decide to go with battery power if you like. If you can’t predict where you’re going to be shooting, this may be your best bet, since battery power is so portable. Obviously, you run a greater risk of running out of power, since batteries only hold a specific amount of power. But you can head disaster off at the pass by carrying extra charged batteries with you at all times. Many battery chargers also include AC power access usually from 10W – 100W. As far as video power supplies go, battery power is one of the most versatile options, and it certainly offers you the most freedom to move around as necessary.
Depending on your particular needs, you may want to use multiple choices of video power supplies. If you might not be near a reliable power source all the time, then you should probably invest in a good battery kit (batteries and chargers) to keep you powered up when the unexpected occurs. When AC mains fail, disconnect or are unavailable, some battery chargers can auto-sense the loss of power and can supply emergency outbound power from mounted charged batteries. Keep a good power cable handy so that you don’t have to waste your battery at times when you can be hooked up to other available power sources. It’s always good to know that you have options, and the power options you have available to you will allow you more flexibility in the way you shoot video.
