In a previous post I talked about how you can run some specific models of video cameras on a external battery source through the USB cable.  Yes you can operate some cameras while the battery is charging.  I was able to record video using my Panasonic video camera and recharge the battery at the same time.  This is really useful when the prices of batteries are sky high.  Or maybe you are taking a long trip away from a power source and you need to charge up your camera.  With an external battery pack, you can charge your camera, phone, mp3 or any other device that can be charged using a USB cord.  So no need to pack separate batteries for each item, save space and weight by packing just one big battery pack.

You can purchase many different sizes of external batteries, some of these are better than others.  I have read reports where some of the real world test results were not nearly as good as claimed (battery size much smaller than stated).  Below is an example of an external battery pack that can be used with a camera to charge it.  I have purchased two of these and they last a long time.  One of them has even had a drink spilled on it, after it dried I charged it and it worked fine.  I keep one of these in my car and can charge up my phone multiple times before the pack needs to be recharged.   The battery listed below is approximately 15000mAH so it is about 4 times larger than a extended battery for a camera, yet cost 1/3 of the price.  There are cheaper versions available, and smaller size batteries but make sure you are not sacrificing quality.  When you need to use one of these, the few dollars you saved may not be worth it when the external pack doesn’t work.

UPDATE:
A company has started making some external batteries specifically for cameras. As a note the capacity of these batteries are a little small at 6000 mAh especially when compared to the batteries listed above. Either way, check them out and decide for yourself. The link to one of these batteries is below.
