I replaced all my travel electronics to be powerable from USB-C. This saved me from a lot cables and adapters.
Even re-soldered the cable of my electric shaver to use a USB-C PD adapter PCB. As long it's somehow close to the standardized voltages (5/9/12/18/etc.) there will be no problems.
Surely the hunting knife you use to kill your dinner when combined with the mirror you use for starting your forraged twig fires, that would be the ultimate solution.
...or just not shave for a few days. I guess you could do that too.
It's a trade off but I think it makes perfect sense after a few nights of not-sleeping directly on the ground under a miniture dyneema tarp.

Without knowing more details about the battery, "20Ah" alone does not convey enough information to determine how long the battery could power a given load for. If I need to power a 100 watt lightbulb, will a 20Ah battery power it for an hour? 10 hours? 10 days? No way to know.
Wh is the unit of stored energy, Wh is what I want to see. Even the official Amazon product page for it doesn't list a Wh figure.
Looks like a guy there measured it and it is 14.7 which is more than I thought it would be.
> So at a nominal 3.7 volts that’s around 14700mAh, which is around 73-74% efficiency. That’s fairly standard. If you perform the same tests with other batteries rated at 20k mAh, you’ll generally see a similar usable capacity.
I was thinking of getting the Haribo one because I like to camp and climb mountains, but I found an old Ravpower battery bank (RP-P819) my Mom got all of us maybe a decade ago and it is 16,750 mAh on the label and weighs 308.5g. I'm not worried about ultralight enough to make that into e-waste and get the Haribo. I guess technology hasn't changed that much with regard to battery packs. The age of the plateau continues.
Then again I am the kind of masochist who used to run ultramarathons with a backpack full of rocks just for the jollies.
Empathise on the gear-lugging - I have Sherpa’d full size solar panels up a pathless and sheer mountainside, and it was not fun - although again standing up there with two tonnes of hardware going “heh, I hand lugged all this here” was gratifying.
At least I didn’t have to carry them back down.
Also do you really need a power bank for a 2-day trip? In airplane mode a phone can live like 2 weeks.

Also matters when your buying things for recreational purposes. Especially when only buying points.
I have to think the Haribo power banks were on the same lines, although it's a bit strange that they're actually being sold on the company's Amazon storefront.
Tradeshow coming up very quickly, previous merch supplier has let the sales team down.
Mid-level Haribo employee responsible for merch finds a supplier willing to rush through everything, because let's face it, Haribo are probably going to pay their bills.
MoQ is 100 units, which is 1 lot.
Sales person intends to order 2000 units, better to be safe than sorry and run out. Accidentally orders 2000 lots of units with 100 units per lot. This isn't noticed until they're already printed and then it's, as they say in the legal profession, no takesie backsies.
Haribo suddenly have a lot more power banks than they have booth visitors, and employees combined.
Rather than store them indefinitely, they sell them off at cost and shift them quickly though Amazon. This drastically cuts down on warehousing space of small lithium (explosive) packs that the candy people have to store.
And kids and grown-ups love it so, with 20,000mAh wherever they go.
10Ah battery is $60, 5.9oz. the 20Ah is 10.2oz and $100. Unlike the Hasbro, it comes close to its rated specification.
My backpacking trips have definitely not needed 20Ah. For two or three nights I can usually get by with a 5000mah, if I shutdown at night and frequently use airplane mode. And my phones are usually getting on, don't have Greta battery life.

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.

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 more quickly than you'd think.

Very easy to bring crap you don't need as well. Always surprised me how much an extra hoodie or something would add to what was on my back. Also there is a 'stupid' light, where shaving grams is silly. Was shrinking down my hammock tarp and discovered my setup was not great when the wind shifted direction.
When it comes to power bricks, smaller things like this is great for the normal laptop bag or purse. This is cheap enough that I'd send it off to be black holed with all the other bricks I lend my kid.

This is so true it's not even funny. I keep a spreadsheet for each trip, and among other things, I record which of the items I actually used on the trips. It was very surprising to me how many things I thought I used and therefore needed, but when reviewing the records, I never (or very rarely) actually used.
Those items get cut from future loads.
