Charging your phone with muscle power?

Question

Charger

It is sad when somewhere the laptop battery runs low and there is nowhere to charge it.
I would like to have an electricity generator for such moments (mobile, without fuel / sun / wind requirements), even if with a not very high efficiency, the main thing is not to depend on external energy sources.
Need information about this kind of devices, and even better personal experience of use.
What I found at the moment: there are many options for phones ( example ), for laptops - Yogen Max (prototype).

Answer 1

The best muscle charge is a car battery. And charging, and I assure you if you always carry it with you, your tongue won’t turn around to say that it’s not muscular, what a muscular one, you’ll drag the dick without muscles)

Answer 2

There are objective difficulties in the implementation of such devices right now - of a technical nature. At the current moment of technological development, for most users it does not matter what kind of additional device to take with them - a muscular dynamo machine or an additional charged battery kit. In a situation where you do not expect a discharge, both are missing, and if you play it safe, an additional battery is cheaper and easier to handle

Answer 3

I have a manual electric generator for phones. Used several times away from civilization.
A few minutes of spinning will allow you to make a short call / send SMS, if we talk about voracious smartphones.
For the full use of the device is not suitable, because. it takes a very long time to turn.
For emergencies only.

Answer 4

I use a converter that runs on AA batteries. Yes, you still need to take batteries with you, but if the supply runs out, then buying batteries is easier than looking for an outlet.
I have a Nokia 5800. bought in the official nokia salon for 1500 rubles runs on a single AA battery and can only prolong the agony of a discharging device.
A similar thing from GP with a miniUSB interface and a bunch of adapters in the kit runs on two AA batteries and is really capable of replenishing the charge by 50% when using good alkaline batteries or high-capacity batteries. It also costs 3 times less.

Answer 5

I haven’t personally used it, but I’ve seen such dynamo machines for charging cell phones in Nix www.nix.ru/autocatalog/cube/29798.html

Well, and others like him, I met several variations.
Naturally, sunny weather and daylight hours are needed)
I didn’t use it myself (there was no need, as reality correctly noted, it’s easier to charge from the cigarette lighter in the car), but an acquaintance lives in the states, he said that they have such things a lot of people use.
