DSD-46FL-2BLU Flashcell Cordless Screwdriver, Blue/Silver/Black

Yeah this works as well as my Coleman Flashcell screwdriver I got way before. I wanted a second one for the house as my Coleman is in the garage shop.Here's my review I posted elsewhere SUBSCRIBEI have owned a Coleman Flashcell screwdriver since about 2009. it does not replace the drill driver (Craftsman 19.2V C3 drill driver with lithium ion cells and clutch) but it replaces small powered screwdrivers for doing repetitive screw driving. The no longer sell them and haven't for several years. I've been wanting one to have handy in the garage shop or house rather than running back and forth.The advantage of a cordless, batteryless driver is that it uses a supercapacitor to drive the motor. The big advantage is that the supercap can be charged in 60 seconds from dead or 30 seconds from half full. That alleviates the problem with cordless screwdrivers i've had int he past that were never charged when I wanted to use them and would take an hour or many more to charge fully, but now its just 60 seconds. The downside is, being a capacitor it has a declining voltage as it discharges. Turns out that its not that bad a deal, it starts out around 200 RPM and when it gets to about half that, its at half charge and you recharge it for another 30 seconds for full charge and 200 RPM again. The slow down is not so bad in my experience.So I see there's now a new company making supercap screwdriver, called BluCave, and the technology is still TM Flashcell.I'd recommend this tool after buying one from Amazon and it came in two days with Prime free delivery.http://www.amazon.com/BLUCAVE-DSD-46...ss+screwdriverThey're selling it for $22.94 which I think is an absolute bargain. Its also for sale at other places (Sam's, eBay) but costs a lot more.Click image for larger version Name: blucave screwdriver.JPG Views: 1 Size: 23.4 KB ID: 825257Review:it has a charger base. The base seems a little large to me and has no keyhole slots for wall mounting, I guess that means you mostly have to have it taking table top space to my disappointment. The base has a line of red yellow and green LEDs showing the charge state and it increments quickly to green when charging in 60 seconds or less. It also has and stores five hex bits and an 2" extension.It comes with a nylon carry case as well.The handle is reasonably small, it can be pivoted to be pretty much a straight handle with the trigger switch on the back or a pistol grip with the trigger on the front of the grip. It has a lock so that it won't rotate around while you use it. I found it comfortable to use, particularly the pistol grip. Using the pistol grip tends to control the torque better since the straight more just tends to pull it out of your hand when it hits bottom. But sometimes you want it to rotate rather than jumping out of the screw head or rounding it off. Too bad, no clutch.It also comes with a LED flashlight head. The head slips on the charging end of the screwdriver over the contacts used for charging. So the five-LED array points away from the driver end. But there's a single white LED on the front that can be used to illuminate the work when driving screws using the pistol grip position. The LED will be below your hand and pointing at an angle to the driver tip. That works well actually. There's a pushbutton switch on the flashlight head to that cycles between the multi LED head, the work illuminating LED and off. There's only one issue - no place to store the head when not in use or charging. Still, you get a nearly free flashlight. It lasts for more than 45 minutes without apparent loss of brightness when the driver is not used and of course recharges in 60 seconds or less.Driver performance - I drove some 2-inch screws into and out of the same hole in a 2x4 until I got tired and it was still was doing a good job. It's not a heavy duty unit with huge amounts of torque but its reasonable for when you need to take apart or put together something with a lot of screws. Like I mentioned the best thing is never having to wait more than 60 seconds to use it and being able to restore a full charge in another 60 seconds. Being a non-chemical battery it will not deteriorate and lose capacity with usage... they claim 100,000 charge cycles but as an EE, I don't think they even know. I suspect the charge base contacts and switch won't last that long, that's more than for many actuators and connectors. And if you want, you can leave it plugged in the charger forever - that saves you the 60 seconds, and with a capacitor, there's no chance of overcharging and ruining the battery as there was with NiCads and even NiMH. It holds a charge for a pretty long time even when not plugged into the charger base (days, at least) although I did not measure it.It has a fair amount of power in the capacitor for a 60 second charge. Its good for small jobs that are a bit more than you want to tackle with a manual screwdriver. I gave up testing the light after 45 minutes. I gave up driving 2" wood screws in and out after about 30. Nicely, it holds nearly a full charge even after a week or more without having to recharge it, short as the recharge is..Overall, I like the unit, for $23 or so its an apparent bargain. It fits the way I work, allowing me to grab it on a moment's notice even if I haven't used it for weeks.

Excellent product for the homeowner with the occasional diy project. Lives. Up to its claims. Chargimg base does not wall mount. Lacks high torque, but seems adaqiate for most projects.

I'm glad I bought 2 because I got to test out one I was going to give as a gift, thank god I had to use mine first to TRY to install 12 screws into legs of a bench where they had already PRE DRILLED the holes for the screws. This thing failed miserably! I ended up having to use my hand with an old fashioned regular screwdriver! This thing didn't even screw in one screw all the way! it's very weak and only good for screwing in screws into drywall to hang something. IMO. I would have been embarrased if I had given this as a gift.

The thing with this product is someone who really does not use tools designed this thing. The collet allows bits to simply fall out and does not grip them. So if you need to use it on a screw that is facing up unless you use one hand to hold the bit and the other to operate the tool the bit just falls out. Great idea that is poorly executed. WAY WAY too expensive for such a poorly designed product

It Works Good, but charge doesn't last long, and not very much torque. 🙂

About 10 years ago Coleman was selling a similar device using the "Flashcell" technology. Mine is still going strong, but Coleman apparently stopped making them. Every couple of years I'd run a web search for "Flashcell" and imagine my delight when I saw they were being manufactured again by another company. This one is an updated design and includes a flashlight attachment and carrying case. I bought 4 of them for Christmas gifts, and they did not disappoint. They charge in under 60 seconds, the device has plenty of torque, and plenty of run time. If it discharges, fear not, because a recharge is but 60 seconds away. Terrific.

Had the product for 2 years nowWorks great and has flashlight on it too. Too bad it doesn't face direction of drill but I have needed it.Recharges super fast. That is a huge plusMight not last a super long time but fast charge makes up for it.It much more torque than similar size small screwdrivers. Tough I have dropped it probably a dozen times never an issue. Why are not more devices flash cell? It is definitely a buy.

These are great for people who don't use things like this every day. Have a quick job that comes up, 1 minute of charge and away you go.The regular li-ion battery devices have advantages like longer run time and power. In the many cases you don't need to use for so long this supercap unit is fine. Even if you do drain it it charges so fast it is no big deal.The issues with other battery equipped devices are that the battery will drain in storage and takes a long time to charge before you can use it.The other big problem with Li-ion battery based devices is that if stored too long the battery voltage will drop too low and PERMANENTLY damage the battery. So you need to remember to charge every so often even if you aren't going to use it. Supercaps need no such babysitting. They can be left with no charge for years but are still ready to go when you need them.
