The Coleman FlashCell Cordless Screwdriver is claimed to need only 90 seconds for its recharge. This definitely takes much less time than whatever cordless screwdrivers that you’re used to. The magic behind of course is the FlashCell cordless screwdriver makes use of a big capacitor in it to store up charge instead of rechargeable batteries. That is why it can be recharged in such a short period of time. Of course, to have much shorter time of charging, there is some sacrifice too i.e the charge stored in the FlashCell would last much shorter than any other equivalent-sized but battery-powered screwdrivers.
Every single full charge of the FlashCell screwdriver can let you finish screwing 22 screws only whereas a normal battery-powered screwdriver shall be able to let you handle up to 37 screws. However the recharge time is as short as one and half minute only (Most battery-powered cordless screwdrivers would take from 30 minutes up to couple of hours for the charging). Furthermore, the capacitor in the FlashCell screwdriver is estimated to be able to handle over 500,000 full-charge cycles as there is no memory effect and it’s able to retain about 85% of its charge even leaving it unused for 3 months. Having the FlashCell for some of your occasional DIY task can save you lot of time as you don’t have to wait for more than 30 minutes or couple of hours for the recharge.

[...] This cordless screwdriver is named the FlashCell from Coleman and has just a 90 second recharge time. It works by using a large capacitor to store the energy. This allows it to be charged quickly and will power it for enough time to screw in about 22 screws. This is lower then a regular battery powered screwdriver which can normally do around 37… but with the charge time being just 90 seconds rather then 30 minutes you will still get way more work done. It can charge around 500000 times which is a lot of screws! It will set you back $99 from FlashCellDriver.com. Via: TechChee [...]
