    @DJM I've been testing a 10W portable panel today and in 1.5 hrs it increased charge of my Pixel 3 XL by 40% before the clouds rolled in. So the claim of approx 4 hrs to charge a phone would be accurate. Weighs 320gm without cables.

    The panel in conjunction with a battery bank might work ok depending on number of devices requiring charging and frequency.

    My old S5 for scale

    Have you tested it with a power bank? I’ve not done it in the field, but my thinking is that solar is better in to a power bank then you can charge your phone at your leisure, also you can do it in a warm pocket etc, I’m not sure I like the idea of leaving my phone out in the cold.

    That is my thinking also - leave solar connected to power bank of a capacity to suit trip length and then charge phone/camera/torch etc at night or when convenient. I expect it to charge fine (panel specs are max 1.9Amps), but will test tomorrow when i remember to bring power bank.

    Panel seems well made and robust, and quite inexpensive (well wholesale anyway ;))

    I’m starting to think that I’ll just carry the powerbank and move faster.

    Take a pack horse or pack dog...either are approved for national park use provided they have a tag marked 'feral'

    Testing under partly cloudy sky this morning the panel charged a small powerbank and 3hrs of clear sky this afternoon has added 60% charge into my phone. Would do better if I kept the panel at right angles to the sun.

    Probably could get the panel and a smallish powerbank under 500gms. Anyway, quite happy with it.

    I think solar panels have changed a great deal since I last researched.

    FWIW, last night I fully charged my phone from 35% using a 10,000mA powerbank and then used the panel to recharge the powerbank today. Partly cloudy day and it took approx 5 hrs with me moving panel to track the sun.

    I'm going to need a 12V power pack soon or I won't be able to do any overnite camping at all.
    Car camping no problems but I can't seem to find anything in a reasonable wight for ski touring and I need a hundred watt hours [9000mA/8 hours] capacity at least. I now can't survive long without a CPAP machine, 3 nites without one and I'm pretty well wrecked. I've been wondering whether a car jump start pack would work well enough.

    Yeah I think shipping lithium batteries around the world is fraught. But it shows that the tech is possible, need to find a local equivalent. I’d start on eBay or Amazon.

    So just to follow up....
    I made a spur of the moment purchase on one of these. 10000mA.
    I was watching the register over $150 worth of food when I noticed it right at the counter. Much the same way a servo places the chocolate right in your face as you pay for petrol.
    Barstools. My brother pulled the trigger on the 20000mA.
    We should be right for a week or so.

    I must add, way smaller and lighter than the old 15000mA I had years ago. I’ve charged up twice so far with an iPhone XR. Still another charge or a tad less in it.

    Yep phones are roughly 3000 so just shy of 3 charges sounds about right once you factor inefficiency.

    Yes I can imagine without kids I would have resorted to all sorts of nerdy shit like this.

    That I’ve managed to rebuild my website is nothing sort of a miracle though.
