how to keep Canon camera batteries charged in the field

deleted

Big external pack?

You're carrying the weight anyway, so this might be more efficient.

Of course, all your eggs are in one big basket in that case.

I use small Nikon cameras and use a spare battery on longer trips. If I bring my phone so I can read my kindle or use the gps or map apps, I bring a small battery pack to recharge via usb cables. It will charge both the camera and the phone, with different cables, up to four times. Never had to use the spare or recharge the camera even on the nine day, even used the camera on a weekend trip a few weeks later without charging it again. The phone was a different story.

I think 3-4 times a day is crazy. I would get a different camera. But I am doing ok with point and shoots. I have my sights set on an upgrade soon; my friend has been using a LUMIX with good results so I am looking into the Panasonics at Costco.

" I can't imagine using a battery a day with the 7D or is there that much of a difference with the 7D Mrk II? "

Yes. I have an original 7D, and its battery usage is moderate. I went to the same place a few years ago and was using up about 1.5 batteries per day.

The new 7D mark II has significantly higher usage, partly because there are more features happening. I can go on a shooting walk for a mile, maybe snapping only two or three shots, and the battery will be down 25%. If I enabled the GPS function, that would be even worse. In fact, the GPS logger function is recording and drawing power even with the camera turned off, if you can imagine that. That's why I leave the GPS things disabled nearly all of the time.

Firing off 10 still frames per second takes a lot of juice. Video lights up the Live View rear screen, so it takes a lot of juice as well.

A point and shoot camera is more of a toy, so I'm not considering that.

I guess if Canon can't make enough profit by selling the camera, maybe they expect to make it by selling batteries.

I haven't given up on the solar panel solution, but right now the 18650 battery solution looks best.

Bob,

I know that you already have an awesome camera, and probably a few good lenses to go with it but…..

If you had a lighter weight camera, you could carry more batteries:) I have gone from canon 6D to Olympus OMD and though I have to carry more batteries, my overall weight is down significantly.

Like you, I have been using a goal zero panel to charge my batteries on longer trips. So, once I need to carry more than 5 batteries, I just bring the solar panel. However, I have also run into times there wasn't enough sun and between that and sub freezing temps, my batteries were sucked dry. Would be nice to have a lightweight alternative to solar charging.

Just to tempt you, here is a link to a thread with tons of shots reminding me that the camera is not limiting my pictures.

Bobs not here

Oh, on second thought he may be reading – hi Bob : )

My theory is he's out hiking, and he'll "come back" and wonder what all the fuss is

Seems like when he was around, there was more criticism, now more love, "Absence makes the heart grow fonder"

I have a very light solar panel about 8" x 14". It has a small battery pack on it, and a USB port. I plug in a battery pack I have, which has LEDs to indicate the charge. The panel can charge the battery pack in less than a day. The battery pack can charge my iPhone twice. I don't know if that is enough power for your needs, but I went 2 weeks and it charged my phone and canon g12 batteries. I'll put a review and pictures on my blog.
