  • Humans are efficient, and there are also huge losses in converting the energy from work to electricity, and then further converting this to whatever voltage you actually need, while also likely first charging a battery somewhere so you can use it at a different time than you are cranking/pedaling…

    However humans are also strong and can think of mechanisms that help with leverage and whatnot; for example an elliptical machine would probably be better than a bike.

    With that being said the power you can generate is still pretty small; around 100Wh is floating around. If you worked out more you’d make more, obviously, but that might not be feasible.

    It’d still be more than enough for essentials like charging your phone though.

    I think your definition of decent charger&cable is just different from me then I guess.

    I expect to get a charger that has the fast charging for the phone (not necessarily the top spec, but high enough) and a usable cable, let’s say a 0.5 to 1 meter, that can also do basic data transfer.

    If I wanted a charger with 4 ports I’d buy it. If I wanted a braided cable I’d buy it. I don’t want either - but I want a charger that I know works fast enough with my phone, and it becomes my travel charger. Everything else I can manage.

    This will be less of a problem as power delivery becomes the norm, but most people probably don’t have a decent PD charger several times over at home. Worst case you’ll have an extra charger where an old one dies, which seems to be common especially with some peoples’ cables.

    Or, you know, alternatively do actually discount the phone by $60 or however much they act like it costs (it’s obviously way less than that, but chargers are still a significant expense largely because they need to have many different SKUs for different regions so the logistics are more complicated).

    Pack-in chargers and cables always suck. I don’t get how people use them, especially those cheap rubber 1m long cables. Utterly useless.

    Any decent company will give you a high-spec charger and a decent cable with your fucking $1000+ phone.

    Deciding to ditch the charger is only to inflate their bottom line, especially if you look at what they then sell the charger for separately.
