This is my first instructable. Note: I WILL NOT BE RESPONSIBLE FOR ANY DAMAGE!

If you live anywhere there is a risk of losing household power and you don't have alternative sources of electricity, you might find this useful.

What you need:

- Ikea Ljusa Crank LED Flashlight ($6+tax)
- USB extension cable
- A drill and drill bit with the same diameter as the USB extension cable
- Soldering iron/gun and solder of course
- Voltmeter or multitester (useful for checking)
- Philips screwdriver
- Knife or precision screwdriver (for prying open)

Step 1: 1. Start Prying

Using a knife or flat precision screwdriver, carefully lift off the front cover. Sorry for the blurred image.

After I pried the cover off, I found out it is screwed on. I assume it was also glued because I could not unscrew it.
<p>Thanks dude - i did this think like you. But - for Xiaomi Redmi 2 you must rotate grip like crazy for watch that he in charching. But i think - even with small speed - there will be charging, only you not see that charhging status. So - if you off yor phone - there will be better charging. In my plans - to do grip on bearings - friction from default grip is annoying.</p>
<p>No problem charging a capacitor..... </p>
<p>hot glue wont hold over time so I would/ will attach It with cable strips or just tape aroind the narrow part. Thanks for the instructable. Been thinking of buying a crank for my project and then this flashlight came along in a &quot;squeeze and guess&quot; present this christmas ;) !!!</p>
They're don't use batteries. They use a capacitor.
Were you able to determine what kind of batteries are used in this light?
Poesis is right, you don't have to keep cranking but you do have to do so every so often (just like when you are using the flashlight).
very nice! do you have to continuously crank while the phone is charging?
No, there are batteries inside the flashlight. Make sure to crank it after awhile so the battery do not die so quickly.
