I also remember some guy at a think tank in the US that covers cyberwarfare saying that one of the surprises was that Russia didn’t try to disable Ukraine’s cell network, either via cyberwarfare or via conventional means; taking out the cell network would do a lot to dick up a country.
Russia didn’t disable the cell network because they were using cell phones to coordinate their forces (as presumably they didn’t have proper radios).
I saw a YouTube video where someone was testing crank powered phone chargers and they weren’t able to get enough juice to ever power the phones. Have you tested it for that purpose?
When you see how little energy a Tour d’France cyclist can generate, with their legs, over a given period of time, it becomes clear why these crank things are useless.
You could possibly charge a phone with a cycling setup, I haven’t done the math in a while. What I recall is the human body makes for a terrible generator.
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.
Arent you supposed to crank charge a battery for a while, and then charge the phone or other device via the battery? Or do you mean they couldnt meaningfully charge the battery at all
I got one after the crazy storms we had over the summer. Had an old cube Nola radio that ran on a 9volt we had growing up but that has long since been lost

Yeah. It’s not like Russia isn’t into dicking up Ukraine.
Russia doesn’t want ukraine or its people: Russia just wants what it probably calls ‘western Russian’ Farmland; and some poor people to work it.

With respect, I’d like to double down on my question and ask if you personally have used it to charge your phone and how well it worked.

I would be legitimately interested in a demonstratably good crank charger, but it seems like there’s a million bad ones out there, that’s why I ask.

100w/hr, cycling constantly? How much food does that require?
It’s just not realistic. As I mentioned, I’d read some math breaking down what a Tour d’France cyclist could do for a battery, and it was paltry.
Better off investing in solar at a rate of 5-10x your battery capacity. Then you can charge reasonably fast in most conditions.
Fair enough, good point.

You keep it in your car, I’m sure your car can charge your phone.

The ladder, they weren’t able to get anything meaningful from a pretty great deal of effort into cranking it.
That’s what you get when trying to charge a phone with a ladder!
But what if it’s a Smart Ladder™?
