ADDING MUSIC TO ROCKETBOX BLUETOOTH
I calculated that these would more then sufficiently charge my phone, tablet, bluetooth speaker and a gopro without ever needing to get a solar charger out.
ADDING MUSIC TO ROCKETBOX MOVIE
I try to do that anyways, but I'll admit its nice to listen to tunes or watch a movie before bed and I find it makes the experience better not worse for me.īefore my second time down the Canyon, this last February/March for a 23 day trip, due to my negative experience with my solar charger, I decided to purchase three 27000mah battery power banks. So essentially the only time it was able to be used reliably and easily was the few hours between getting to camp and sunset and I just didn't find that to be sufficient and ended up doing what many advocate for by just leaving it all in a dry box and enjoying the canyon on its own. At least with that Goal Zero 7 charger, it didn't fully provide the needed amperage to charge stuff unless it was in direct sunlight and but not so direct that it overheated the solar panel. Its also useless in obvious times like sunless days and at night. I also found that it was sensitive to high heat and would stop charging once it got hot which is pretty crazy for something designed to require direct sunlight. Even during the flat stretches you gotta make sure they are in direct sunlight, so frequent adjustment is needed. They aren't water proof, so you have to constantly be taking them in and out of dry storage. I was using the Solar panel a little bit to try and save the battery banks, but found them to be very finicky. Everything I need to charge on a river trip is USB based (phone for listening to music and taking pictures and tablet for reading and multimedia use), so this worked fine for the first week until I had depleted the power banks. My first trip down the ditch I had a Goal Zero solar panel and two medium sized battery banks. I know plenty like the solar chargers, but I found it to be much more efficient to get a bunch of high capacity battery banks and charge them at home then to have to worry and fuss over a Solar panel all day. I've always been an advocate for bringing more batteries rather then a solar charging setup. I still us it for multi night trips and makes for a great light tool for camp, I can run X-mass lights off of it all night and have an LED set up for my boat. The over all concept that I had was valid I would just go with a smaller battery and larger panels. I did end up getting some great footage and pictures so it was worth it but would like to be more efficient next time. Also I would simplify the set up it was a lot of gear to manage and took more time than I liked. In hind sight I would use a smaller battery and larger panel. I also added a inverter, Stanley makes one that looks like a regular duplex socket and worked really well it did not get hot and I was able to run a hard drive and laptop off of it. Also everyone on the trip was able to charge their gadgets.
The size of the battery did end up being a benefit because i had issues with the connection for the solar panel and was not able to recharge the battery. I was afraid us using a lead acid battery in case of a flip I did want to have to deal with the leakage. The battery was in the 900 cold cranking amp range and a dry cell. Lessons learned the panels that I had were too small for the task and the battery too big, (it was the one I use for my camper so i so i figured i would use it). So my solution was to build a large river battery in a rocket box with a solar panel to charge it during the day. I was also worried about storage capacity for my video files so I took a external hard drive and a lap top to be able to empty the MicroSD cards from my cameras. The trip was 16 days and I was worried about having enough power to keep all my gear up and running. I had 4 GoPro's and mirroless camera my phone and some Bluetooth speakers.
I ran the Grand in 2016 in May and wanted to do some extensive filming and photography. So let me see if I can respond with out getting to lengthy.
