If you’ve been doing HD video you know how fast those batteries drain. The standard Canon LP-E6 and LP-E8 are 1,800mAh and 1,120mAh respectively which will shoot video for about an hour.
You can always have some spare batteries to replace the dead ones, but Chris Winter shared a pretty cool external battery hack that uses a 10,000mAh which is roughly 9 times the capacity.
Now, I am not sure if you can actually call off the shelf products a hack, but between the fast that you get so much more usage time and the clever way Chris mounts the battery with Velcro, I thought it is worth sharing.
