Manufacturer description

The UnaMela 140-IN-1 Mini Electric Screwdriver Set is built for the kind of teardown work PC builders, retro-hardware tinkerers, and phone repairers actually do. At its center is a pen-shaped cordless electric screwdriver with five torque settings from 0.15 to 0.35Nm and a 200 RPM top speed, so you can back out laptop case screws quickly and still dial the torque down for a motherboard standoff. When a screw is seized, the included manual precision driver gives you the leverage a motor can't. The kit ships with 120 CRV precision bits covering Phillips, Torx, Flat Head, Triwing, Hex…

SpecPicks Verdict

SpecPicks scored Mini Electric Screwdriver Set 140-IN-1: Small Electric Screwdriver… using a rating × review-volume × price-fit model applied to published specs and reviews across the tools & maintenance category. UnaMela's tools & maintenance lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for tools & maintenance: PC towers accumulate significant dust in 3–6 months, so cleaning frequency drives cordless vs. canned-air tradeoff decisions. Match the device's RPM or CFM rating to your case size, and confirm battery runtime covers a full tower cleaning before ordering.

Frequently Asked Questions

Will this open a PS5 or a Macbook?

Yes. The 120-bit set includes Pentalobe, Torx, Triwing and Tri-point patterns, and UnaMela lists PS4, PS5, Macbook, laptop, phone, drone, RC car and keyboard work as intended applications.

How much torque does the electric screwdriver actually deliver?

Five gear settings spanning 0.15 to 0.35Nm, with rotational speed up to 200 RPM. That range is aimed at electronics; it is not a substitute for a power drill on wood or metal fasteners.

How long does it take to charge?

About 60 minutes for the 350mAh lithium-ion battery over the universal Type-C port, so you can use the same cable as most phones and controllers.

What tools come in the kit besides the screwdriver?

19 repair tools across 12 types, including an opening pick, fiber spudger, Jimmy, flex extension, angled tweezer, suction cup and magnetic mat, plus a manual precision screwdriver for higher-torque screws.

Is it worth it over a plain manual precision set?

If you do repeated teardowns, the 200 RPM motor saves real time on the dozens of identical screws in a laptop or console. Check the listing for current warranty terms.
