The BoostTurbine 4000: A unique portable charger

cnet.co/15msJEV
This gadget charger has a hand crank to turn elbow grease into energy.

[@KneelB4Bacon]

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.

[@bluecatdk]

It would work just use a voltage regulator

[@walkingmed8430]

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

[@josef959]

1 or 2 revelations per second... come on CNET

[@Mako2-1]

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

[@Emsyaz]

It takes 2 Prophets to power this up.

[@nanorazor]

It would great if they put a extra solar power panel on one and plastic instead of the metal finish so it can be lighter

[@Altairific]

I'm guessing it's good if for traveling in remote destinations where access to electricity is limited. Not for everyone, but it's something I'll keep in mind if I need it.

[@ntinos81]

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.

[@elessal]

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

[@adkitchen]

What a revelation!

[@914050]

So, how long would you have to crank it to charge your phone? Let's assume their talk time number comes from the iPhone 5. 1 min. cranking = 4 min. talk time (according to this video) iPhone 5 has a 1440 mAh battery / 8 hours talk time = 160 mAh per hour 160 / 60 minutes = 3 mAh per minute TT 3 mAh x 4 minutes = 12 mAh (you can crank per minute) 1440 (battery capacity) / 12 (mAh per minute)= 120 minutes It will take you about 2 hours of cranking to charge iP5. About 4 hrs. for Galaxy Note 2.

[@cuddles6938]

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.

[@nismo5707]

Well done

[@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.

[@jakubrejzekjunior7349]

Interesting thought. There are many such devices on the market which do not include the battery. Why are the ones with battery liked more? Because the time where you could handcrank the battery can be sometime else than when your phones battery is dead. Like you can crank the battery during breakfast and charge your devices at a later time. Another point is that there are many USB electronics you could power from this which lack battery. (Arduino chip, fan, light and many simular) This adds this power bank another kinds of uses.

[@musicalhistory4392]

Do you have a review on a solar based charger?

[@silverssonyoutube8438]

4000 ? damn i thought it only went upto 2000 so i got that .

[@Tagout10593]

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

[@bananekmelounovy2225]

Or child with ADHD

[@therealmattx]

I, too, have ADHD or a child

[@leaf5524]

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

[@a7madramadan]

OMG a Hand Crank ... I'm all in :D

[@andisusilo7463]

wow...cool

[@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.

[@1.gio.1]

What if you cHarge it and move the crank

[@WorldTourWithJatinder]

I WANT TO BUY IT .WHERE IS AVAILABLE ?

[@0194D]

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

[@BleachedWheat]

How much is it!?

[@maquindesign9158]

I am looking for this in 2024

[@frankeggers7694]

I have one but use it.

[@Rize_Inn]

Best thing about this video, no wedding ring! Just kidding Sarah, keep up the good work.

[@mx5hong]

It should also have a built in solar panel.

[@Kongolox]

nice.. rly nice

[@FictitiousMe]

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

[@eagles2249]

Daedalus phones can be good for flashlights and other things calling is not the only thing

[@icydragon68]

I like it I want it

[@Zorr3n]

Cranking! Good for remote areas where electricity has not reached yet.

[@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.

[@RynaxAlien]

Press crank or breath powering is better

[@ashikgurung1236]

World's should create more hand crank

[@cuddles6938]

Just ask Ed Begley, he put his generator on a 10 speed bike, he rides it in the morning and charges whatever he needs to charge.

[@slightlycold-bear6671]

Shouldn't Dong Ngo be doing this segment?

[@MiyuruWeerarathna]

Neat battery extending feature.......but not quite worth it. Good review

[@Jandyman95]

*revolutions...

[@DDELFIERRO]

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

[@Asist0ne]

They should have called it a power brick.

[@hustla4sho213]

I am impressed with this Crank thing, but how long are we gonna wait for a solar power solution to charge our phones once for good..is it much to ask for? common tech people!

[@CookamoAndStevensSon]

One or two revelations per second?? Ahhh! OHH! WOW!

[@aldinlapinig]

a hand crank... hmmmn..throw in a solar panel for self-charging and i'm in... :D

[@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.

[@elradiuzi]

Keep pressing 7.

[@zero2zero4]

this is good for zombie apocalypse

[@hashsquad73]

coooooooooooooooooool

[@SunilKvallath]

Go for a solar charger. Easy and portable.

[@slidedesigncuber]

Lol.... Love the vids

[@jaimepaiva8847]

"revolutions", not "revelations".

[@fahrizanmefibahidayat7819]

I never use the one I have

Was this create in the don't age.

[@josephdaniel1999]

Weekends.

[@sasitharshan6267]

Weather a bower bank have 10000 mah with dianomo..Please tell

[@slate1496]

I use this to charge my 16000 mAh portable charger. It work decently but not the best. I vote solar

[@freddyfrediere8275]

KA-PA-WA

[@r2stik]

GO WITH 11000mAh SOLAR!!!

[@JoshuaHilbig]

one or two revelations per second?? AAAAAhahahahhahaha nice

[@DDELFIERRO]

4 minutes of talk time is likely more than necessary in a real emergency. Those who went days without electricity post-Sandy & Katrina could have used just such a device and there are other devices such as lights that could be USB powered. Care to describe another way to reliably & repeatedly generate the same kind of power while (literally) in the dark?

[@harunmedia5136]

[@jason7033]

Trash

[@tepeke88]

Biggest and most stupidest feature here: cranking! What is this the early 1900s?!

[@cunningwolf4516]

tepeke88 what's wrong with cranking? Power is out, outlets don't work what are you gonna do now? I think it's handy to have things separate from replicable batteries or the power grid.

[@SeanManks]

1 min charging gives 4 mins talk time. Who is going to do that? Waste if time and money.
