I like those little portable battery packs. They come in all strengths and prices. I think you'll be surprised how little your batteries need charging. If you're out of cell phone range, that's one you won't have to charge. Lots of chargers have a plug-in for the car, so you always have power available, if you are close to your car.

Check out eBay. Search for "power bank".

[quote=TexasLynn]Hello everyone! I have been following your posts for a few months and have learned enough to know, I have a lot to learn! I will be going on a trip to Vancouver Island and will be without electricity for 3 days on a kayaking trip to view Orca whales. Do you have suggestions for not having electricity? ]

Hi TXLynn - Take a look at the Luci Pro Series here: https://mpowerd.com/

They are light weight, waterproof but do need sunlight to charge/recharge.

I highly recommend Luci products. chase

I have a T1i and a T4i, 2 batteries for the T1i and 3 for the T4i, never have run out of juice on either , that said I probably would not download to the computer until I got back to shore, I doubt I'd even carry the computer on the kayak, considering shooting on the kayak , I'd pick just one lens and not plan on changing while on the water

one of the most useful camera battery travel accessories I bought was a 2 up 5v usb powered charger. Works a treat whatever the power supply (car usb, solar, power bank backup) I bought them without batteries as prefer well known branded batteries for proven capacity.

I've got them for Canon, and Panasonic. Also got a single battery model as a backup. If no access to wall or car power, I tend to use whatever I have to charge a power bank then use that to charge the camera or phone battery (more steady power supply). Really like the look of the wind up jobby mentioned earlier by JHC but as I am never out of power contact for days on end it falls into the category of another 'really useful tool that I never knew was essential' and as I get older I seem to be buying more and more of those!

Just did a Google search for "solar camera battery chargers" found a company that looked interesting, not too expensive , check it out for yourself as YMMV, works from a battery as well as solar, looks like you build your own kit from their parts, Bob.

Take three pre-charged batteries and three 64GB cards for the camera (one for each day). You may not need them, but starting each day with a charged battery and fresh card should get you through a day of moving and shooting, since you will be spending some of your time paddling. Also, do you really want to change a card or battery while paddling a kayak? Turn your equipment off while moving to the next stop. Also take one backup power supply for your laptop. Again you may not need it since you (hopefully) will not be spending much time on your laptop. Personally, I would leave the laptop at the base camp rather than deal with the weight or give up valuable time I could spend enjoying the trip.

I have purchased portable charging devices from B & H. I used one of them to charge my computer and cell phone in the car on a trip with my family. Everybody had so many devices plugged into the car plugins that I needed something. My daughter was working by computer on the trip and granddaughter was doing what 13 year olds do.Check out B & H Camera Photo Video. I am sure they have something that will work for you.

Get a battery grip. It holds 2 batteries and has a AA battery tray if the batteries quit. That alone sould get you through thousands of photos

I looked at the charging options for your EOS T3i and it appears that you have to use the battery charger that comes with it (120v) so it appears that you cannot charge your batteries on the trip without bringing an inverter and 12v battery. There appears to be no port on the camera that would allow you to charge the battery in the camera by plugging in a micro USB cable connected to an external battery that others have suggested.

So, it appears that you will not be able to charge batteries while on the water. Before you go you can find out how many photos you can take before the battery dies and how many shots will fit in a card. Fully charge a battery, put in a fresh card, and start taking photos into the battery dies. Turn off all the options that will drain the battery and take shots. You can use the LCD to frame and review photos but this will lead to more draining of the battery. After you are done, you will have a better idea on how many photos you can get off a battery. If you get 300 shots per battery and expect to take 200 shots a day, a battery will last 1-1/2 days (roughly). Likewise, see how much of the SD card has been taken up by the photos you took. If the 300 shots you took take up 6 GB (300 x 20GB/shot), then you can shoot the 3 days on one 32GB card.

There have been suggestions on transferring photos from a SD card to another without the use of a computer for backup/safety. These may be able to be run off the portable battery packs that others have suggested.

Look into getting a dry bag for your camera while on the water, Murphy's Law does not stop at the water's edge. Another option is a waterproof camera such as an Olympus TG-5.

Which one did you purchase for charging your computer?

When I am going on a long trip, I don't plan to upload anything on the 'puter until returning home...........keeping all the images on the cards. However, there are portable charging tools that can work ok for charging the batteries. I usually travel with both enough card and batteries to last, not having to re-charge anything until I am again in a place that has electricity. I own five batteries, and cards for at least 300GB.

I suggest you read through my recent thread asking for tips on cameras and kayaks - http://www.uglyhedgehog.com/t-521932-1.html
The overwhelming responses were advising to not do it, and I was only thinking of an afternoon paddle around a pond on Cape Cod.

A thought on carrying a backup on this type of trip. Unless you want to carry two dry bags with camera and batteries in one and a backup device in the other (stuffed way up in the point I guess) there may not be much point in bring the backup along. If you dump and loose your equipment, you loose your equipment including your backup. Staying light and keeping your primary equipment secure might be the best approach.

Of course if you have a traveling companion willing to carry your backup (sort of an off-site backup), that could work. You could also carry their backup if they need.
