Fenix e-star mechanically charged emergency light?

With the troubled times of the moment and the worst ones to come it's no surprise that they made a tool like this.
Crank lights are often weak mechanics, this could be more reliable.
Any information on the price? I wouldn't buy it but I'm just curious what the cost is.
Edit: I found the cost, $ 36.95

If you go to Amazon and write "hand crank light" there is a great choice..including lanterns (hand crank lantern)
But because of my difficulties with English I did not express myself well, it is not right to define this Fenix as one crank lights.
Its mechanism is certainly more comfortable and reliable than a crank, reminds me of the old Soviet torches from the 70s.

This one from my father in law (in Germany).

I've had my eye on this light soon as I heard about it. I dont think it's to bad. i'm pretty sure you can put a rechargeable battery in it and recharge it by cranking it or just a regular AA battery. Where are they for sale now?

On pre-order at Fenix store

Looks like you can install a regular AA. Your supplied nimh will usb-c charge, or the hand pump charges a capacitor.

I saw that. What happens if your using a regular old AA and you crank it? Will it try to charge the battery?? That won't work out real well 😁

I wondered that, too... 🤔🧐
full metal casing? nice
Probably won't. The power output from your hand motion is as unstable as it gets, not to mention its power level. Probably aren't enough to charge the battery, if not destroy it.

Then how can you charge a rechargeable AA in it then?
a diode is an easy fix to this.
Crank and shake lights evolved to LEDs with rechargeable solutions after failing to be much more than a toy using incans. I grew up loving these lights because simply put I couldn't afford to feed incan lights this small batteries all the
time. When white 5mm LEDs hit the market I'd already abandoned mech lights and when the LEDs showed they could operate at very low power levels and still put out usable light that was the game change as incans back then you could get about 2 hours or so on a #222 bulb using 2AA alkaleaks before the light started drooping to orange/red nothingness. With 3AA and a resistor light that theoretically should give you 3 hours at the same light level a couple of parallel 5mm LEDs could run up to about 20 hours at higher levels to start with and drop to sub lumen useful levels near the end.
With todays high capacity lithium ion cells, LEDs 5-8 times more efficient and drivers that have multiple output levels you can get a lot more lumen hours out of them such that mech lights cannot compete. Unless you only have a chance to have a single light with nothing else a good battery light with additional batteries and a rechargeable setup with external charging solutions and extra batteries wins over getting a repetitive motion injury wiggling lumens out of a mech light for hours even days before you toss it in a box somewhere so you can ignore it till the next garage sale.

It states you can. That's why I'm confused. I mean trying to recharge a non rechargeable at all is bad.

Absolutely agree. But, still it's cool😁

Wouldn't that apply to plugging in the usb-c charging cable with the alkaline in it? Wondering if it has a electronic charge protection that detects rechargeable vs non?
Absolutely cool. Reminds me of the presents I got from my aunts when I was a kid.... cool but not really useful or that fun. I think I still have a credit card gizmo somewhere in a box that I never used and a handy dandy dial-o-matic dog polisher.
