The ES120 smart motion controlled screwdriver from e-Design is definitely one of those products that you don’t necessarily need, but one that you wouldn’t be without if you have it. For any serious drone builder or RC modeller, the ES120 could save you a surprising amount of time changing screws and generally fixing things.
Built into the screwdriver is a 3-axis gyro, which detects motion, enabling you to control it with just a slight turn of your wrist. To use, simply press the screwdriver firmly against the screw, hold the power button and turn your hand slowly in the desired direction as if you are turning the actual screw. Turn it to the left and it will spin to the left, turn it to the right, and it spins right. The more you turn your hand, the faster it will spin which makes using it very intuitive. The screwdriver has five torque levels and an automatic mode where it will increase torque as necessary to turn the screw up until it reaches its maximum and then stops.
The ES120 isn’t cheap for a screwdriver, but it’s certainty a quality product and addictive to use. It has a slim CNC'd 304 stainless steel body about the size of a marker pen, with knurled grip for comfortable holding. It’s also equipped with an OLED screen for a bright clear display, which shows the working status, battery level, and load of the driver. It has a built-in 300mAh battery for wireless operation and fully charged it will give up to 60 minutes continuous use, which is plenty for a normal day’s usage. Recharging it is straightforward, it’s USB powered so just plug it into a computer or phone charger.
This is the upgraded version of the original ES120. This Plus version comes with 16 high quality alloy screwdriver bits, which include Philips, Slotted and Torx Hex’s.
Note: The ES121 screwdriver has now been discontinued; the ES120 Plus is its replacement. The main difference is it uses a 1:144 reduction gearbox vs. the 1:64 found on the ES121. The no load speed is slower on the ES120 170rpm vs/ 380rpm, but it has more torque 2.5kgf.cm vs 15.kgf.cm so it's better suited to removing tighter fixings.
ES120 Plus Mini Electric Screwdriver has set a new standard for electric screwdrivers. It is an electric screwdriver with a compact structure, smart and exquisite appearance, as well as the function of motion control recognition.
