90 Second Charge 130 Year Usage
Here I will present a flashlight. Flashlights have always been useful, however, you often think of the cell problem... When will it stop working? I better not to use etc. :) Anyway, we are in technology era. Throw away that cells :p
A flashlight called Light for Life, after 90 seconds of charge, serves 120 minutes of usage. In this flashlight, led technology is used and can be charged 50 000 times.*
If we do the math, daily 120minutes mean 130 years of usage. That's why they say light for "life". However, the price is not so reasonable, $169. For detailed information of product and buy, you can look here. And here is a presentation video.
If you have much money and don't know where to spend, here is a good alternative :) Fine product but I wish price would be around $50...
