So, even though I'm getting old (maybe because of it) I'm planning on returning to The Bend this winter, solo again after many years of bringing my kids, to do some long-distance backpacking.

Long distance backpacking in BB...like a thru hike?
Where?

I started backpacking Big Bend in '95 and explored it extensively for a decade, mostly on established trails but some off-trail trips, too. For the last decade, I've been taking my family with me. I turn 60 this year and my wife and young kids (I'm a chronic procrastinator) have agreed to give me a few weeks to return alone and explore some of the areas that I don't know very well.  It's been a long time since I did a severai-day solo trip, but there is nothing I love more than hiking solo especially in areas where people are few and far between. I'm going to stitch a few of those together in December and see what happens.  I'll post trip reports when I return home.

This isn't an answer to your question, but you may find useful information on battery conservation and more here:

OK HMoD I am back in country and you have maybe already seen this by now but here is the thread on Experiments in ultralight solar from the Backpacking Light forums, it seems specifically aimed at I-phone recharging too.  Bob Gross and Richard Nisley and the other big minds all chime in.  Very detailed and interesting (I have not read the whole thing closely).

At roughly 3 oz., depending on how much power it produces, you might could realistically cut out a number of items like you are thinking about and come out ahead weight wise.  It would be an interesting experiment but I would also want some redundancy in case of some failure until proven to take field abuse but of course you know that.

Thanks, ME. I have NOT seen that particular thread. Bob Gross may put me a bit into the wee :icon_wink:ds, but I'm going to go through all of it.  3oz is amazing. That could lead to an enormous weight savings by empowering (literally) the multipurpose use of my iPhone.

Update: my iPhone5 is currently experiencing all sorts of memory glitches and failures that make it a very unattractive option for backcountry consolidation. I still think it may represent the future of backcountry electronics, but not on this trip (Winter 2016). I did follow the BBC advice and purchase the Petzl E-lite which is everything it is claimed to be. Awesome piece of technology. I'm going to forego the dedicated GPS altogether (I still prefer USGS paper quads). But I'll take my old McMurdo PLB. And I borrowed a POS P-A-S  ;) camera equipped with a GPS tagger, so I can still tag location photos with coordinates. I've playing around with the DIY solar panels ME referenced in his Backpacking Light link. Because I'm an epicly incompetent electrician, I have not yet perfected them and probably won't be able to take them on my upcoming trip...but the set-up is cheap and awesome and it WILL work eventually. Which means goodbye spare batteries for everything and hello endless iPhone charge. Next trip for me, it's iPhone only.   :great:

The folks who know about such things charge a battery with their solar panel in case they encounter clouds.
Sam's Club ran a one day sale recently. I ordered a pair of Honeycomb DASH 10 batteries for $26 in my hands. They weigh 8.24 ounces each including the micro USB charging cable. The batteries can be charged while also charging an appliance. 2 USB outlets.
I'm currently checking the number of charges for my iPhone 5s.
Very pleased so far.
