Ah damn i forgot to put the hardcore guy carabiner on the ring
Bottom flap is open to show the sharing guy double USBs
How big / small
Worth buying for the compass alone.
135 mm x75 x 15
Pretty small then, looks noice.
Give a us a field test report when you can.
And only $50.00 at Harv's
@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'
I’m travelling light these days @GS. Fewer toys and on skis.
. Panel, cable and 10,000mAh power bank weighs 590gms...ouch
I’m probably carrying that in whiskey and chocolate. Priorities......
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.

Be nice if either of those was sold to Australia
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.
Saw these while browsing for something else and they mention cpap, not quite the capacity you were after though...
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.
Any performance report yet?
Can’t say I’ve used my powerbanks much in lockdown......
Why not? Perfect time to run a series of controlled tests.
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.
Free labour / research assistants.
Yep. It died. Like the other ones. Grrrrrr
Bugger, couldn’t hack the pace or warranty job?
This could work: https://outbax.com.au/bundle-hyunda...tation-bag-solar-mat-solar-cable-jump-starter
Just stopped working. Radio parts are shut for walk-ins, but maybe in a few weeks ill take it back and see. I kind of dont want another one that dies after a few months

Jaycar now have a decent range of 12V Lithium batteries; I am looking at the small ones for now. Easier for a nonce like me to work in a standard I'm used to: ie 12V
Weight is a relative thing but lineball with the largest Ryobi 18V battery and lighter is a small Lithium
I may be setting up in and around Pretty Valley next season even if I can't afford a lift ticket. Probably my last time tho.
I've priced the "Correct" battery for the travel CPAP machine [ OMG I hate being tied to a device] and it's list at $599- and on sale for $499-
So I can get a decent solar panel, a charger, a battery box with multiple outlets including USB and a reasonably sized Lithium deep cycle for that and be self contained.
50W flexible panel $139- Controller $90-, Battery box $60- totals $289- The difference would pay for a large battery
Well reasonably sized anyway.
Just large enough to power the car fridge for a couple of days in summer as a bonus
As if I could carry one of those in my rucksack Hah!
But there is a problem with using 12V car batteries for my personal needs as they need a new style charger and none of my existing battery chargers will work with Lithium Deep cycle batteries
The website says the Jaycar battery is 3 kg. Are you stashing it away before the season?
I'd carry it in with all the other gear. It might take 3 or 4 trips with the sled tho. It is only 8 klicks and a doodle if the weather is clear
these people claim their lithium batteries will charge from all existing chemistry chargers, might be worth investigating;
Aldi had the Cygnett 20k mAh for 70 dollars this week
