Backpacking is spartan and uncomfortable by comparison. And with canoe camping, much more primo sites and much fewer people around.

So that's why it doesn't align with existing industry units and always requiring conversions...
Thank goodness SI units are power-of-ten based so converting between watt hours and joules is just a matter of moving the decimal place. Oh, and throwing in an ancient Sumerian constant approximating the number of Earth rotations as it revolves around the sun once.
Also, I wonder how usable a unit of time that was not based on a day would be, since so much of our life revolves around that cycle.
I guess I default to assuming this is BS? I was in the market for a 20Ah battery to power my Burning Man totem last month. I ended up buying two off Amazon - a no-name brand and an Anker for 2.5x the price ($65 for 28Ah). The Anker bank was heavier than the no-name and had substantially longer battery life under the same usage patterns. I don't know a lot about batteries, but what I do know is that they're very impor…

It weighs 205g/7.2oz.
> Ultralight culture seems a little nuts to the uninitiated. I prefer "Durable, but as light as possible", not the other way around. Most ultralight gear breaks after a few uses or when it is mishandled in anything-less-than-perfect conditions, which, happens a lot outside.
Packs used to have MOLLE/PALS strips and/or external pockets. Packs made now seem to have supersonic flight aerodynamics as the primary design feature… heaven forbid we add 20 grams of stitching/webbing for expansion/versatility.
Why your [ultra-light hiker] friend suddenly has [the world's lightest] power bank. I remember Colin Fletcher, years ago, writing in The Complete Walker about trimming the borders off his paper maps to save weight, which seemed like an insane over-optimization to me. But then, I'm not an ultralight hiker. I am impressed folks are getting their loads down to 10 pounds though.
That insane over-optimization is how folks are getting down to (and below) 10 pounds. I'm not even remotely an ultralight backpacker, but I do count ounces (no matter what your weight limit is, you can't escape making tradeoffs to stay within it). Your hiking load is a great example of how quickly apparently insignificant quantities can add up. Saving fractions of an ounce multiple times gets you large savings far mo…

Do seconds have anything to do with the Earth rotating around the sun? I thought a second just has to do with the Earth’s rotation on its axis. Also, I wonder how usable a unit of time that was not based on a day would be, since so much of our life revolves around that cycle.
Compare Mean solar day vs Stellar day vs Sideral day - the difference is less than 5 minutes or so.

Tangent: as a web performance consultant, I've sometimes used "shaving down half the toothbrush handle while carrying a bowling ball in your backpack" as a metaphor for misguided performance optimization efforts.
To turn it back around-- your entire codebase is on the hiker's back. They feel its aggregate weight with every step . It's all literally in the hot path. When bugs show up in the form of back pain, "pre-optimize everything" sounds like a sensible option to me.
There are better options out there. I recently bought the INIU 10,000mAh 22.5W powerbank from Amazon for $29.69 CAD [0]. It weighs 205g/7.2oz. [0]: https://www.amazon.ca/dp/B09176JCKZ
