4.0 out of 5 stars It's a charger!, July 30, 2008

I mean, what can you really say about it? Place battery in charger and watch it charge! Very exciting. It comes in a large red box. The charger is small and should be easy to store while traveling. I don't understand why Canon does not include this with the camera. Well I do know, more money selling it by itself. A very useful item to have. Very expensive for what it is but what choice do you have. 5 stars for design of it but it loses a star for the price.

5.0 out of 5 stars Shaves recharging time by about an hour..., July 6, 2008

This is awesome. I always get the portable charger when I get a camera that does not come with one. They save alot of time and headaches. Easy to travel with. It is also great to throw a spare battery on to charge in a hurry (I can honestly say, I dont think I ever used the power cord from my old camera.)

It also shaves 50 min off the recharge time for the standard battery, even more for the extended battery.

5.0 out of 5 stars Smart charger to protect your investment, December 25, 2008

The Confusion:
There seems to be some confusion why the charger is recommended when the videocam seems to originally come with one.

If you own a videocam like f.e. HF11, HF10, HF100 etc. or any other you will find included a POWER SUPPLY !! <-- read this ? ... let it sink in ...

Its true that the power supply can - while its connected through the videocamera - charge the battery, but that is NOT what its made for primarily.


The difference:

a) A power supply does not care if your battery is half full or empty it just connects it and keeps it connected even after it became already full. A power supply also doesnt care if the battery is charged slow or fast.

b) The charger has some intelligence built in. It does communicate with the battery and checks the battery status. It then (dis)charges it GENTLY to the maximum possible and keeps it at that state. It stops loading when the battery is full and indicates with the green light that charging has finished.


The result:
Using the power supply regularly will reduce the lifecycle of the rechargeable battery, hence it will suffer an earlier death.


The charger itself:
- the charger gives each of your batteries a personalized treatment
- Its true that the packaging is helplessly oversized
- I found the charger to be comfortable AND robust enough for travelling
- NO messing with cables
- You can charge one battery meanhwile using the other on the go


--- How this charger protects your videocam: ---

- maximizes the lifecycle of the battery
- reduces the usage of the compact power supply connector on the videocam

You MUST plugin the power supply to the videocam in order to copy the video data to the PC/MAC. Those connection plugs usually break after warranty time. Thats another reason why the charger is recommended.

So, try to use the power supply not too often, or at least very gentle when pluggin it in/out to avoid disappointment or save your videos on the SD card.
