The Videographer's Outdoor Power Core: How to Power a Camera, Monitor, and LED Light Simultaneously
You have found the perfect outdoor environment. The lighting is gold, the setting is right, and you have a clear vision for creativity. And then the camera monitor goes dead. A few minutes later, the camera's own battery does the same. The inconvenience of having to juggle numerous incompatible batteries is a familiar ballad of despair for any videographer. In order to work professionally, you require a single source of power. In this guide you will learn how a single powerful outdoor power bank can be the hub of your rig while simultaneously providing power for your camera, monitor and LED light while you are busy filming.
The Battery Juggle: The Problem with Standard Setups
The off-the-shelf video kits are a tangled mess of proprietary batteries. Your camera quite possibly uses a Canon LP-E6 or a Sony NP-FZ100. Your monitor and LED light probably use different Sony NP-F type batteries of different capacities. The various brands of batteries use different chargers, presenting a complicated set of gear to carry and work with.
This system is not only inefficient but also unreliable. It forces you to constantly monitor multiple battery levels, interrupting your creative flow to swap them out. Running out of a specific battery type mid-shoot can bring your entire production to a halt. This is a common challenge that requires a more robust piece of outdoor power equipment to solve.
The Solution: A Centralized Outdoor Power Core
The solution is to shatter the mentality of individual batteries and think about a centralized power core. A current high-capacity, high-output power bank can be a single source for the whole camera rig. Rather than a half-dozen small batteries in a bag, you carry one solid package you can trust that will power the rig for hours.
This method reduces your rigging hassle by a significant amount, cuts weight, and exponentially multiplies your shooting time and reliability. It's not just a camera power bank for in-venue video production but a commercial device for squeezing your in-location workflow and a pros' necessary investment.

How to Calculate Your Total Power Consumption
Before you can choose a power source, you must understand how much power your gear actually needs. This involves looking at both the instantaneous power draw (Watts) and the total energy needed over time (Watt-hours).
Find the Wattage of Each Device
Every piece of gear has a power consumption rating, usually listed in watts (W) on the device itself, in its manual, or on the manufacturer's website. If it only lists voltage (V) and amperage (A), you can calculate the wattage by multiplying them (Volts × Amps = Watts).
Here are some typical estimates for a common setup:
Mirrorless/DSLR Camera (via dummy battery): 15-20W
5-7 inch External Monitor: 10-18W
Portable LED Panel (at medium brightness): 20-50W
Add It All Up for a Total Wattage
To figure out how much total simultaneous power you consume, you simply add up the wattage of the devices you use at the same time. Continuing from our example: 20W (camcorder) + 15W (screen) + 30W (lamp) = 65W. It thus requires a power source capable of at least 65 watts under constant use. It's good practice to include 20-25% overhead for power spurts.
Calculate Capacity (Watt-hours) for Runtime
Wattage indicates the speed of energy use; watt-hours (Wh) indicate the capacity of the fuel tank. To determine how long a power bank will continue, you require the rating in terms of Wh for a power bank. When a power bank simply displays the capacity in terms of milliamp-hours (mAh), you can work the same out using this equation: (mAh × 3.7V) / 1000 = Wh. In a 27,000mAh device, this converts to approximately 99.9Wh.
To calculate your needed capacity, multiply your total wattage by your desired runtime in hours.
Formula: Total Watts × Hours of Shooting = Required Watt-hours (Wh)
Example: 65W × 3 hours = 195Wh. This tells you that a single 99.9Wh power bank is not enough for a 3-hour shoot; you'd need a larger unit or multiple smaller ones.
The Output Ports: DC vs. USB-C Power Delivery
The port type for a power bank is no less significant than the capacity. To video pros, the very first and topmost priority outputs are high-wattage USB-C PD and versatile DC ports.
The Power and Versatility of USB-C PD
USB-C Power Delivery (PD) is a smart charging spec that can supply up to 100W (or more with PD 3.1). That's ideal for powering today's laptops, some camera bodies directly, and many newer monitors. The "smart" here is just that—it talks to the device and supplies the best voltage for the best experience. It's safe and effective.
Why DC Output is a Professional's Best Friend
Although USB-C is great stuff, professional video gear still overwhelmingly uses DC barrel connectors for power. A specific DC output in a power bank provides a few important benefits beyond USB. It presents a rock-solid, unregulated voltage (e.g., 12V or 16V) that many devices prefer. It is a more efficient power pipeline more often because you won't encounter the power loss inherent in having to convert power for a USB outlet, and thereby get slightly longer runtimes for your equipment.
How to Avoid Power Interruptions and Equipment Damage
The very last thing you'd want is for the power source to cut during a take and possibly corrupt the footage. To avoid this, pick the appropriate gear and handle it appropriately.
Choose a Power Bank with Sufficient Overhead
You need the maximum continuous wattage of your power bank to exceed the total calculated wattage of the rig. If you consume 65W of gear, a 65W maximum output power bank will be operating at full maximum. It can lead to overheating and instability. A 100W or 140W output device allows for a safe buffer and provides stable and reliable outdoor power.
Use High-Quality Cables and Connectors
Your power solution is only as strong as its weakest link. Low-cost thin cables won't achieve the necessary current and cause devices to turn off. Upgrade to properly rated dummy batteries for your camera, heavy-gauge DC cables for your peripherals, and accredited 100W USB-C cables. A solidly constructed power bank for photographers and videographers is worthy of good connections.
Professional power equipment offers "clean," rock-stable power, devoid of surges or dips harmful to sensitive electronics. A good power bank offers a stable voltage across all equipment without monitor flickering or camera restart. A high-watt source, such as the 300W total output of the EcoFlow RAPID Pro Power Bank, gives you this much-needed stability.
Building Your Rig: Essential Cables and Accessories
Once the right power bank is chosen, you require a couple of essential accessories in order to hook everything together in a smooth rig.
Dummy Battery: This lightweight adapter installs in your camera's battery compartment and cradles a cord which hooks you up to a remote power source (DC or USB-C), giving you basically unlimited runtime.
DC Barrel Connectors: Ensure you obtain the correct size of DC barrel cables for the monitor and LED light. The 5.5mm x 2.1mm is standard but double-check the device specifications.
D-Tap Splitter Cable: If you have a D-Tap outlet (which bigger units possess), a splitter cable lets you power more than one DC device using a single outlet.
High-Quality USB-C Cables: Be sure any USB-C cables you employ are 100W or better in order to support the power requirements of your devices properly without bottlenecking.
For an outdoor video rig producer, devising a centralized power core is a life-altering decision. It exchanges the hassle of a multitude for the ease and security of a couple of high-capacity units or a single one. With the proper estimate of power draws and a device of the proper capacity and outputs, you can work for hours without having to stop. It allows such freedom for you to work at the shot and not at the gear. You have the possibility of having a multi-purpose device like the EcoFlow RAPID Pro Power Bank with high-watt outputs and cabling integrated.
