Looking for input/guidance on Solar Power Bank recommendations for a backpack NWT Sheep hunt. 12 days potential in the field. Powering InReach, phone and hearing aids. Hoping to get feedback from actual experience. Help?
 
Add up total amount of wattage needed or device uses for a start. Are you going to be on the move or in a place for longer durations? Finding something lightweight mire compact for ease or..........
If you can leave it open to receive recharge you could be added by a battery pack.

More info needed on how much power is required
 
I'd also google Gritty Hunter. They are going steep and deep for weeks at a time and running all you listed plus camera gear as well. Sometimes they are leaving the solar panels at camp sometimes on their pack top during the days.

Not a sheep hunt but I went on a remote hunt and took two 10,000 battery packs. My backup batteries and those added lots of weight I wouldn't take again even on horseback. You don't "need" half of what you think you do. A PEAK headlamp or knock off is magic and one of my best finds. Think bear on carcass and LOTS of light is worth $$$

I also practiced letting devices run down and recharging to see what that ate up and that was helpful. I would color code or mark charging cords next time too for finding correct one in the dark. (paint pen) Remember, all lithium and batteries must go in your carryon too so this takes up quite a bit of a man purse.
 
I've had good luck with this combo. I've had the battery pack for 3 years and used the solar charger for a 6 day pack hunt this year. The solar charger will charge the battery pack full in 5-6 hours. I tested before I took it out on the trip with the same results at home and on the mountain. I used it for Inreach, headlamp, and phone (OnX).

 
I run the NiteCore NB20000 energy brick. Little heavy on the weight, but size is small and has enough capacity to leave the solar chargers at home for many days. Another thing to think about is if you're hunting with others you may be able to get away with a much smaller and lighter charger if everyone is going to carry their own, or everyone shares a high capacity one.
 
Anker solix or goal zero. That said, as a pack hunter who hunts like this all the time…I recommend against this.

It's unnecessary weight, and solar panels are hard to get legitimate charging from because the sun is moving, and I'm hunting. Clouds and canopy can be an issue too, though I would suspect you'd be above treeline. They are also expensive considering how poorly they work.

You'd be better off using only the power you need and conserving, and bring like two of these https://www.bestbuy.com/site/anker-...6_jemjBhwb4P3c-s6DsaAm0pEALw_wcB&gclsrc=aw.ds
 
I've used these for multiple seasons in Alaska and home in the western states. They weigh 12.5 ounces and are 20,000mAh.

I don't know your requirements but I powered my phone, headlamp, InReach and clients phones
1 battery lasted about 3 weeks of usage. Your mileage may vary. 1 trick to make things work better is to keep the battery above 40 degrees as well as what is being charged. My experience was the battery charge lasted longer. I would charge inside a coat pocket next to my core.
I'd take 2 batteries and leave the solar panels home.
As stated figure your needs. Only power up the devices when needed. You'll be surprised how much power you can save.
Make sure to disable your cellular data, wifi and all unnecessary apps to conserve power

I spent a month on Mt McKinley climbing it in -20 degrees. Took an extra battery for my phone (that's when you could swap out batteries) some extra AA for my Garmin ETrex, Petzl Head Lamp came with big Battey, and had a 26,000mAh Battey pack for recharging items. Had to look at weight for climbing so everything small. Never ran out of power. Turn off Phone completely and other devices when not in use.
 
Which Petzl Head Lamp model did you use?
I just went looking for it, but it is somewhere with the rest of my climbing gear that I still have. Probably find it tomorrow. I will say that it was not a LED , but was bright and had about a 2" Lens and Bezel. Then on the back of the head harness was the battery back. The Battery was about 2 1/2" x 2 1/2" and lasted forever. It was the Light that is used on climbing Mt. Everest and all the BIG Mts. That was years ago and now they use LEDs.
Thanks
