The BoostTurbine 4000: A unique portable charger

This gadget charger has a hand crank to turn elbow grease into energy.

[KneelBBacon]

I worry about connecting expensive electronics to a hand crank with a variable power output, so what I particularly like about this unit is that it has a built-in 4000mah battery. Once you finish cranking/charging it, you can just let it charge your devices from the battery with a smooth, uninterrupted power flow.

“One or two revelations per second”? You’d have to be a shaman to power this thing...

[walkingmed]

This is actually a nice gadget to have in long travels or camping trips :] not the most powerful charger but certainly a versatile one :]

[ntinos]

hand-cranking or pedal powering is good for fitness and fun. As they mentioned, this kind of devices are emergency power Banks. It is not possiblw to power a cell Phone fully in one hour.

[cuddles]

I use the PowerBank looks like an oversized Lipstick case. Has 2600mah and is easier to carry around then this big square box. Just buy two of them and your good to go. It uses a USB to Micro USB cable for charging it, and then insert your devices USB end to the stick and the other end to your device and your good.

I WANT TO BUY IT .WHERE IS AVAILABLE ?

[RynaxAlien]

Press crank or breath powering is better

[umkh]

Obviously signals travel a lot further than where the tower is located. Also i've been to countries where they have the so called 'load shedding', basically where the government decides to cut out the power supply for half the day or so. Even keeping your phone charged becomes a problem and this device would be perfect for those places.

a must-have for the zombie apocalypse and time travelers.

Sarah Mitroff. Did you stop the video right before they showed her name?

[workkevinw]

Why didn't they use capacitors instead of battery?
Less toxics to dispose of and if its a crank charger why would you need to store the energy?
And it would make it very light and useful long after the battery unit has burned or blown up.

[Tagout]

use the hand crank as a fidget toy if you have ADHD or a child.

What if you cHarge it and move the crank

[mxhong]

It should also have a built in solar panel.

[DDELFIERRO]

Spare battery could be equally dead to begin with if not charged/maintained. Solar power charger takes much longer to trickle enough power into the battery than simple manual labor can generate. Solar would be a good option to maintain a constantly charged battery but it doesn't work at night, indoors or all that well in inclement weather.

So...the faster you crank, the faster the battery charges?

[FictitiousMe]

If electricity has not reached the area, how does the cell tower work in that area ? Have you given it a thought ?

[slightlycold-bear]

Shouldn't Dong Ngo be doing this segment?

[floriangrey]

Charging an ipod nano battery with solar panel is doable but charging a 2000mAh battery allready takes 4 hours to charge on an power outlet.

[DDELFIERRO]

They already exist but they charge slower than this would and not as reliably.
