Charging Digital Cameras from Solar Power

How do I use solar power to charge my camera battery?

Step 1. Identify Your Battery Type

Remove your battery and look for the model number on the pack. This is typically a short alpha-numeric code. Below are examples of the Canon BP-511 and the Nikon EN-EL8 battery types.

Step 2. Purchase the Appropriate Charger

The charger supplied with your camera most likely requires AC power may not have a DC power input required for solar charging. We have a variety of battery charger cradles available that accept DC input and have been tested to work well with solar.

Step 3. Connect the Battery to the Charging Cradle

Step 4. (4W and 8W Bags for Handheld Electronics) Connect the Charging Cradle to the Solar Panels

Disconnect the V11 or V39 battery pack Switch the output of the circuit box to 12V. Using the supplied 3.5×1.3mm barrel adapter, connect the camera battery charging cradle to the 3.5×1.1mm female socket from the output of the panel circuit box inside your bag.

Step 5. (4W and 8W Bags for Handheld Electronics) Point the Panels at the Sun!

Step 6. (for Laptop Chargers) Connect the Charging Cradle to the V60 Battery

Select the 12V setting Connect the Car Charging Socket to the DC output of the V60 battery Connect the 12V DC Car Charger supplied with the battery charging cradle to the socket Connect the 12V DC Car Charger to the battery charging cradle Or you can connect via our 3.5×1.3mm adapter from either the battery or solar panels directly to the charging cradle

How long will it take to charge my camera battery?

On the battery, you'll see a Voltage (typically 3.7 or 7.4V) and capacity (e.g. 1200mAh). Multiply these numbers together and divide by 1,000 and you'll get Watt-hours. A 7.4V, 1200mAh is a 8.9 Watt-hour battery. With our 4 Watt solar bags and solar chargers, each Watt-hour of battery capacity takes about 35 minutes to charge in direct sun. So an 8.9 Watt-hour battery will take about 5 and a half hours to charge. For our 8 and 10 Watt bags each Watt-hour takes about 18 minutes. Our 16 Watt laptop charger will be slightly faster.

Is there a list of which camera uses which kind of battery?

This is constantly changing, but here is the most recent list based on data from photo sharing site Flickr.

How do you recommend storing my camera gear in your backpacks?

We think both the Domke 414 and the Camaroo Compact III camera inserts fit well in the Array and OffGrid. The Domke 414 holds a lot more gear and is more plush, the Camaroo is better if you want storage room left over.

Here's a short video showing the Domke and Camaroo in the Array Solar Laptop Charger.
