I have looked into a number of solutions to power 12v devices:
- Goal Zero battery packs (too expensive? $300+)
- 12v sealed lead acid battery with adapter (too dangerous? impractical to recharge? ≈$50)
- Anker Astro Pro2 20000mAh (would this even work? ≈$80)
I have a Goal Zero solar panel which ideally I could use to cycle the charging of my power source(s) during the daylight hours. One of my use cases might be heating a large family tent and I don't really want to use propane as an energy source. Are there alternative (low power draw) heating solutions that might work for this use case?
- I'm already bringing at least one fully charged Sherpa 50 power pack as I use it for several other things as well. So, I'm kind of trying to maximize its utility during the trip.
- In fact assume any battery I bring will be fully (solar) charged prior to the trip and will (hopefully) only need a partial trickle charge during the sunlit hours.
- An electric blanket adds insulation on its own even without supplying power.
- An electric blanket has an automatic shut off after 30 min, and moreover will only be used intermittently during the night. I don't intend to draw 8 solid hours of power for this blanket each night.
Additional devices I'm considering running on these batteries:
- Frying Pan
- Electric blankets
- Air mattress pump
- Anything else?
Extra credit implied question:
- If one were to go all in with solar powered camping; what would the ideal core of that system look like?... and why?
