I have taken lots of batteries for a laptop and camera, and auxiliary power bricks for USB chargeable devices. Your shooting style will dictate how many cards you use. However, I would give some thought to how important it is to get you images into a laptop on location. To make a backup all you really need is a RavPower WD-03, which will allow you to copy files from an SD card to a USB memory stick, using a phone to initiate and monitor the process. It is also a 6000 mAh USB charger. Eliminating the laptop will lighten your load considerably, and you won't need to bring a source of 110 V power.

I recently took a trip to Ireland with just a Sony RX10M4, shot 1500 raw images and all I needed was a single 32 gb card. But the camera's battery, which I could charge leaving the battery in the camera and connecting it to a aux battery, would require daily, and sometimes 2x daily charging, as it is only good for about 400-600 shots.

Hey TexasLynn,

You may also want to seriously consider bringing a second external HD for backup. Just saying...

Enjoy yourself, be safe and don't forget to post when you get back would love to see some of what you get while out there.

My suggestion would at least 6 CF or SD cards, using 2 each day, and as you said at least 3 extra batteries, plus water proof floating bags.Also store the cards in separate bags, just in case. I wouldn't mess with the laptop.

You may not take as many photos as you think. You have a typical DSLR which will be a chore to keep dry - you may not be able to just whip it out to get photos whenever you like - you WILL be bouncing around in a kayak on salt water.... I have done a similar trip in the past - camping out on islands off the coast of Vancouver Island. I took a small point-and-shoot that I could keep in a zip-lock bag for easy access and dry storage. This was before the age of GoPro - I might have considered taking a GoPro strapped to my chest. I ended up mostly taking photos when we were camped or stopped for lunch - so batteries running out was not a problem. One of the most awesome things I have ever seen was an old-growth red cedar that we camped under on a small island - it must have been 20 feet in diameter!

Another option, though, would be to get a battery grip for your camera and take extra AA batteries.

Battery Grip is your best choice in my opinion. Uses 2 standard Canon batteries or 6 "AA" cells. $119.00 at B&H. They have cheaper ones, but I prefer OEM Canon. Keep everything in dry bags as stated above. Plan on lots of rain--remember it's a rainforest.

Hi Lynn first, check your camera if you can recharge the battery via a usb cable as many "bigger" cameras you can not do it, you need an external 110 volt charger or a 12 volt to 110 volt invertor charger , so this will exclude any solar panels! Regarding how many cards, its be said that you might not be taking a great amount of photos so I think you should plan for max of 200 per day. I shoot raw and jpg and never fill my 32gb card on vacation (African wilderness safaris) per day and I have 2 cards per camera. I do take along 3 sets of 32gb cards with me on a four day trip into the bush without downloading them onto my laptop that stays in the camp. I only review my images once I've shot them just to make sure that the lighting and focusing were ok otherwise I never review them at night to save battery power. I do take with me 2 extra batteries, one for each camera. Don't take the laptop with you, leave it at home you don't need it! Go as light as possible as there are little packing space on a canoe and its going to be wet. Waterproof bags are a must plus a cloth to wipe splash water from your gear. Enjoy the trip.

I have used these whilst traveling in Europe; didn’t want to recharge nightly simply as a mater of convenience. They worked well and held a charge for a couple of days....(3 maybe??)

Might want to experiment @ home to see their level of efficiency.

First of all I would dump the DSLR and go pocket waterproof camera. I have been on week long canoe and kayak trips to Ontario and weight and convienance becomes a big factor. Around the Pacific Coast you can bet on lots of rain and or high humidity. Dry bags are a fact of life. You may get careless and your equipment will go for a swim. The SD cards will be fine but the camera and lenses won't. You may also consider a small solar charger such as the ones from Harbor Freight https://www.harborfreight.com/catalogsearch/result/index/?dir=asc&order=EAScore%2Cf%2CEAFeatured+Weight%2Cf%2CSale+Rank%2Cf&q=Solar+charger
I also have after market chargers that plug into 12v just like the solar chargers but in the rain it may take all day to recharge one camera battery. A big plus on the pocket waterproof cameras is that they do not eat batteries like your DSLR does.
I lost a lens and the roll of film that was in the camera at the time the wave came over the top of the canoe. Yes the camera got soaked but it was an Exackta and was strictly mechanical and not even a light meter. It dried out near my campfire. My other lenses were safely zip locked bagged.
I would never consider anything other than one of the pocket waterproof cameras. Remember the reason for the trip is to get out and enjoy the environment not to be National Geographic.

These look interesting; I use their power tools & am always surprised @ their staying power.

Maybe a few of these charged of course:

I have the 70-300 DO IS USM and would not trade it for the lesser lens. I saw that review and laughed. I am on my second lens, my first recently went swimming. The DO lens is in between the typical consumer lens and the L lens. with regard to three days kayaking, I have a T4i and an 77D. Canon claims that the T4i battery is good for 400 shots only using the viewfinder and the 77D, 600. I would take at least 4 or 5 batteries and probably a solar charger. Even on cloudy days there will be some charging. To me the issue is when will you have time to charge. Unless you can have the charger set up on the hull of the kayak you will not have much daylight time and then you have the issue of keeping the connectors and the charger dry.

Kayaks are not known for dry rides and equipment can get damaged so easily. Unless the total purpose of the trip is to take photos, I would get a good point and shoot and a couple of extra batteries and have a ball. Dry bags are OK but I would not want to tote my good camera and laptop around in my kayak for days. That is just me, however, wither way I hope you have a wonderful time!

You did not state what make/model your camera is. If it is one that can accept 2 memory cards, I would use the availability of 2 slots as back-up. Set the slots to “backup”. This way, your image is recorded simultaneously on BOTH cards. If your camera has this feature, my personal approach (since you shoot RAW) would be to bring 2 cards per camera for each of the 3 days you will be without electricity. Remove the cards at the end of each day and keep them in 2 separate locations - one on your body and one. Put new cards in each day whether or not the cards are filled. The optimal card size would be dependent on the MP’s of your particular camera. I would also advise you to start out on morning one of your three days with SIX fully charged batteries for each of your cameras.

My husband and I regularly travel to areas without reliable utilities, and this is the method I personally use. In a couple of weeks, we are heading out to a few weeks in the African bush. We will be traveling in a motor vehicle, but we have been warned that we may not be able to count on being able to recharge our camera batteries as frequently as we would need for a variety of reasons. I am NOT going to take the chance of running out of battery power. LOTS of batteries will be going with me.

Enjoy your trip and share your images with us here on the Hog. And welcome to the “family”.

You dont say what kind of camera you have so I am going to say that if it is a Nikon, you can look at the battery grip for the camera, and many of them will allow you to use the ENEL18 battery... it is equal to about 3 regular batteries. it is expensive, but certainly works. I got one for my D850 to use to get the 9 fps, but have now since found that I can shoot all day and usually 2 or 3 days without an issue. unless you are an extremely prolific shooter, 2 or 3 of those batteries will last the entire trip. If you decide to do this, the nikon battery is about $150 each, the charger is $369 but I bought a watson charger for $69 and am extremely happy with it... and the grip, well it depends on which camera you have. The knock off grips seem to work pretty well. I have the Nikon one for my D850 and a knock off for my D800 I cant tell the difference as far as the battery usage is concerned... just a thought.

When a friend of mine goes to Oshkosh to watch/intermingle w/ all the planes there, he borrows some of my batteries...we have the
same camera. He takes 4 w/ him and doesn't have to recharge. He does take a lot of "moving/action" photos, but I doubt he captures
them in raw. Hope all goes well on your trip...please post some of your photos when you return.
