Power Station for Camera Charging: USB and AC

What to look for in a power station for camera charging

When you shop for a portable power station to charge cameras, drones, and their batteries, the two figures that matter most are the station's continuous output in watts and its capacity in watt-hours. The continuous output tells you how much power the station can deliver at any moment, and the capacity tells you how much total energy it holds. The EIA explains that electricity is measured in watts, a unit of power, and that a watt-hour is a unit of energy, which is what your station stores.

Your camera gear charges in two ways: through USB ports, which many cameras and drones support directly, and through the AC wall charger that came in the box. A power station with both USB and AC outlets covers both. The USB ports on a station are rated in watts, and the AC outlets are rated by the station's continuous output. Read those figures on the listing and on the maker's page to see what each port supports. For a broad selection, see the best portable power station guide.

• USB-A and USB-C ports for direct charging of cameras, drones, and accessories
• AC outlets for the chargers that came with your gear
• Continuous output in watts, which tells you the total power the station can deliver
• Capacity in watt-hours, which tells you how much energy the station stores

USB charging for cameras and drones

Most modern cameras and many drones can charge directly from a USB port, either through a USB-C cable or with the cable that came in the box. The wattage a camera draws when charging is listed on the charger or in the camera's manual. A power station's USB ports are rated in watts, for example 60W or 100W on a USB-C port. Match the port's rating to what your camera needs; a port that delivers more watts than the camera draws is fine, because the camera only takes what it needs.

For drones, the battery charger is often a small box that plugs into AC or USB-C. If it plugs into AC, you will use the station's AC outlet. If it plugs into USB-C, you can use a USB-C port on the station. The station's USB-C port wattage is printed on the listing, so you can compare it to the charger's input rating. To understand USB-C power delivery better, read USB-C PD and power stations.

AC charging for camera batteries

Many camera battery chargers and drone chargers are AC devices, meaning they plug into a wall outlet. A power station's AC outlets deliver the station's continuous output in watts. The charger you own has a wattage rating, usually printed on its label, that tells you how much it draws. As long as the station's continuous output is higher than the charger's draw, the charger will work. The station's AC output is a listing figure, so read it on the product page.

If you plan to charge several batteries at once, add up the wattage of all the chargers you will plug in at the same time. The total must stay below the station's continuous output. The station's output is a maximum, not a recommendation, so the maker's page will tell you the exact figure for each model. For a guide to output ports, see power station output ports explained.

Capacity for a day of shooting

The station's capacity, measured in watt-hours, tells you how much energy it can store. A watt-hour is the energy used by a one-watt device over one hour, as the EIA explains. For camera charging, capacity determines how many battery charges you can get before the station needs recharging. The listing states the capacity in watt-hours, and the maker's page may show how many charges a specific device can get, but this site does not provide runtime figures.

A small station with a few hundred watt-hours is enough for a day of charging a camera and a drone on a campsite. A larger station, in the 1,000Wh range, gives you more charges and can also power other gear like a laptop. The guides on this site group stations by capacity, so you can compare models in the range that fits your trip. See best 1,000Wh portable power stations for mid-size options.

Port types on a power station

Power stations list the ports they include, and for camera work you want USB-A, USB-C, and AC outlets. USB-A is common for older cameras and accessories, while USB-C is the standard for newer gear and can deliver higher wattage. AC outlets are essential for chargers that do not have a USB option. The listing will show the number of each port and the wattage of the USB-C ports.

Some stations also include a 12V car outlet, which is useful for charging accessories that use a car adapter. The port list is part of the listing's stated details, so you can compare it to what your gear needs. If a port's wattage is not stated, the maker's page is the place to check. For more on 12V outputs, read what is a 12V output.

Recharging the station with solar

If you are on a multi-day trip, you may want to recharge the station itself. Many stations accept solar panels, and some are sold as a bundle with a panel. The solar input is a listing figure, usually in watts, that tells you the maximum power the station can accept from a panel. The EIA explains that solar energy comes from the sun, and the DOE notes that solar panels work in all climates, though the amount of power depends on conditions.

A solar bundle is a convenient way to keep your camera gear charged on a long shoot. The panel's wattage is stated in the listing title, for example a 100W panel. This site does not provide charge time figures, so read the maker's page for details on how the station charges from solar. For a selection of solar bundles, see best solar generators.

What to pick for your situation

The right station for camera charging depends on how much gear you carry and how long you are away from a wall outlet. A photographer on a day trip can use a small station with USB ports and a single AC outlet. A drone pilot who needs to charge multiple batteries might want a mid-size station with higher USB-C wattage and more AC outlets. A filmmaker on a multi-day shoot will benefit from a larger capacity and a solar panel to recharge.

Use the guides on this site to compare stations by capacity and output. The buying guides list the stated details of each model, so you can match the ports and wattage to your camera gear. For camping-specific needs, see best portable power station for camping.

Questions

Can I charge my camera directly from a power station's USB port?

Yes, if your camera supports USB charging. Check the camera's manual for the charging wattage, then compare it to the USB port's rating on the station's listing.

What wattage do I need for a drone battery charger?

The charger's wattage is printed on its label. The station's AC outlet must deliver at least that wattage, and the station's continuous output must be higher than the total of all chargers you plug in at once.

How many charges will I get from a power station?

The number depends on the station's capacity in watt-hours and the wattage of your charger. The maker's page may list charge counts, but this site does not provide runtime figures.

Do I need a power station with AC outlets for camera charging?

If your camera or drone charger plugs into a wall outlet, yes. Many chargers are AC-only, so a station with AC outlets is necessary. USB-only stations work only for gear that charges via USB.

Can I charge multiple camera batteries at once?

Yes, if the station has enough ports and the total wattage of all chargers stays below the station's continuous output. Add up the charger wattages and compare to the station's output figure.
