The Blucave Flashcell Cordless Screwdriver

The Blucave flash cell Driver

No doubt you have probably made the jump to cordless power tools, some advantages and some drawbacks, the freedom from the cord of corded tools, with the requirement to keep battery packs charged and ready.

Another alternative not that often adopted is the super capacitor, this also has advantages and drawbacks.

The Blucave flash cell driver is a light duty type electric screwdriver powered by a super capacitor. The storage of a capacitor is less than a battery by size but has the advantages of rapid charging. The driver will literally recharge by the time you get up and get a cup of coffee and return to the bench.

When using the Blucave driver, plan to keep the charger close by. For light duty applications at the bench, the Blucave driver is lightweight, supplies enough power for things like disassembly and assembly of small and medium hardware.  When working on other projects like appliance maintenance, bringing the driver and charger to the work location save steps.

Perfect for working on projects like electronics, and other mechanical fasteners that don’t require huge amounts of torque.

The Blucave driver has a hex socket end that accepts bits, sockets and drills. The Blucave driver is supplied with a small assortment of bits , I purchased an addition set of drill bits with the hex end to use with the driver. With a quarter inch square adapter,  🔨 half 🔨  🙂  quarter inch drive socket sets can be used with the driver. If you already have assorted bits, like hex, security, and torx drivers the Blucave will drive all of them.

The handle rotates and locks either in a gun or straighter position with a one button lock and also forward and reverse buttons.
The supplied charger base is large enough to hold the driver and has a space for holding frequently used bits for easy access.
A row of colored LEDs indicates charging status.

This driver also comes with a zipper case, and an LED flashlight head that attaches to the end of the handle where the charging contacts are. The flashlight attachment has an additional single LED that faces in the opposite direction.

Not having to worry about keeping cordless driver’s batteries charged, the lightweight of the driver, quick charge turnaround, and having it on the bench ready to go solves a lot of problems.
