We set up a camera to record a time-lapsed video using a five minute shutter interval, and our results are a bit surprising.
Not only does the XP18000 give you the most battery life per pound, but it also charges the fastest.
Remember, charging times are a double-edged sword. Ideally, you want a nice slow charge so that your battery lasts more than a few hundred cycles. Fast charge times get you back away from the wall socket faster. But in the long run, they cut down on the health of the battery.
Brunton implements the most conservative charging scheme, but this solution may make more sense if you are considering pairing it with one of the company's solar panels for a trickle charge.
