It's useful having an external battery charger for your Panasonic camcorder, especially as they seem to eat batteries. This pack gives you that external charger, plus a spare 1790mAh battery (the same size that normally comes with the camcorder).
I'm glad I have the external charger. However, if I had my choices again, instead of buying this pack, I'd have bought a larger 3580mAh battery
and a better third-party case, such as Amazon's own camcorder bag
. The larger battery would mean less worry about having to change it at that critical moment, and the case that comes with this pack is frankly disappointing. It has a velcro strip to stop the camera flopping around, but it doesn't seem like it's the right shape or size for the HS60 (the camera is lost inside the bag), and the padding doesn't seem enough to keep an expensive video camera safe.
