Re: Ultralight Backpacks Used by Women on the JMT and InReach/Garmin units

Regarding charging of phones with solar panels, there has been a lot of past feedback that charging phones directly from solar panels can be problematic. An issue that was raised repeatedly for iphones is that as you move from sun to shadow, the phone would stop charging and "go to sleep", and wouldn't necessarily start charging again automatically when the panel was back in the sun (as in, hikers would have to unplug and replug the power cable back into the phone to restart the charging process). I know most people here say that they charge a powerbank and then use the powerbank to charge their devices, which I think is the preferred solution. Just flagging the other issue for anyone who might not have heard or experienced that before. In terms of daytime charging efficiency, I also read that the difference in performance between NOBO and SOBO hiking directions was negligible, the key limiting factor is forests, shadowing from high valley walls, etc. which is the same issue regardless of hiking direction. The sun sits high enough in the sky during summer months that you don't get a major distinction in solar panel performance during the day whether hiking north facing or south facing - panel sitting on top of your pack facing the sky instead of strapped on the side of your pack will make a bigger difference.

I took an ECEEN (brand/company on Amazon) 13W panel on the JMT for my various devices and it was great. I had enough things to charge to make it worthwhile (phone, InReach Mini, Kindle, headlamp).
It had two USB ports and could charge two devices in parallel. I had it clipped it across the top (not back) of my back and I would charge up a small powerbank so I could charge my phone at night.
It wasn't sold as 100% waterproof so I would put it away when it rained hard. But it got wet. No issues.
I had an older panel of theirs with a single port and both have worked for years.?
