Sad happens when the laptop battery sits and no place to recharge.


I would like for these times to have the power generator (mobile, no fuel requirements/sun/wind), even with not very high efficiency, the main thing — not to depend on external sources of energy.


Need information on such devices, and even better personal experience.


What is found at the moment: for phones a lot of options (example) for laptops — Yogen Max (prototype).

The best muscular charging the battery from the car. And charging, and I assure you if you carry it always with you, you can hardly say that it is not a muscle, any muscle, dick dragged without muscle )

There are objective difficulties in the implementation of such devices right now is technical. At the moment the development of technology for the majority of users no difference extra device to take with you — a muscular Dynamo-machine or an extra charged battery set. In a situation when you do not expect level — both do not exist, and if reinsured — an extra battery is cheaper and easier to handle

I have a manual power generator for mobile phones. Used a few times away from civilization.
A few minutes of twisting will make a quick call/send SMS, if we talk about voracious smartphones.
To make full use of the device is not suitable, because need to twist a very long time.
Only for emergency situations.

I use a Converter that runs on AA batteries. Yes, you still need to bring batteries, but if the stock ran out, then the batteries easier to buy than to look for an outlet.

I have a Nokia 5800. Z. W. bought in the official salon nokia for 1500 rubles powered by a single AA battery and can only prolong the agony of the discharging apparatus.

The same thing from a GP with miniUSB interface and a bunch of adapters included powered by two AA batteries and are really able to make up the charge by 50% if you use good alkaline batteries or battery packs. It is 3 times cheaper.

With regards to if mobile, then, in addition to what you already suggested above, there is another interesting option: www.sotmarket.ru/product/Universal_solar_charger.html
Well, like him, have met a few variations.
Of course — you need Sunny weather and daylight hours)
He did not use (need did not arise, as rightly pointed out reality, easier still from the cigarette lighter in the car to charge), but a friend living in the States, told me that they have these things a lot of people enjoy.
