$36.99
Product Overview
The Mini Electric Screwdriver Set 140-IN-1 by UnaMela is a precision-engineered toolkit designed for electronics repair, maintenance, and general disassembly of small devices. Compact and ergonomically shaped like a pen, this electric screwdriver offers professional-level performance in a portable form. Ideal for hobbyists, IT technicians, locksmiths, and everyday users who work with delicate electronics such as smartphones, laptops, drones, gaming consoles, and more. With over 140 tools included—120 precision bits and 19 additional repair implements—this set supports a wide range of disassembly, reassembly, and fine-tuning tasks. Built-in shadowless LED lighting and smart auto-stop technology ensure accuracy and protect both components and the user’s wrist during intricate operations.
Key Features
- Built-In 4 LED Shadowless Lights: These bright, evenly distributed LEDs eliminate shadows and provide clear visibility, making it easier to work on tightly packed circuit boards or inside sealed enclosures without external lighting.
- Smart Auto-Stop Technology: This innovative safety feature detects increased resistance and automatically halts rotation to prevent over-tightening. It protects screws from stripping and safeguards your wrist from strain—especially important when working on sensitive electronics like motherboards or touchscreen assemblies.
- Long-Lasting 350mAh Battery: A high-capacity lithium-ion battery powers through more than 700 screws on a single full charge, ensuring uninterrupted operation for large repair jobs or multiple projects without frequent recharging.
- Fast Type-C Charging: Fully charges in approximately one hour using the included USB-C cable. The built-in LCD display shows real-time charging status and powers off automatically once complete, preventing overcharging and extending battery life.
- Ergonomic Pen-Shaped Design: Lightweight and balanced, the pen-style handle offers comfortable, fatigue-free handling during extended use. Its intuitive grip allows for precise control, whether you’re tightening a tiny screw or loosening a stubborn panel.
- Five Adjustable Torque Settings (0.15–0.35Nm): Fine-tune the output for different materials—from soft plastics in phone casings to harder metals in laptop frames—ensuring optimal torque without risk of damage. Lower settings are ideal for delicate electronics; higher settings offer more power when needed.
- High-Speed Motor (Up to 200 RPM): Delivers efficient rotational speed for quick assembly and disassembly, reducing downtime during repairs or upgrades.
- Comprehensive Bit Selection: Includes 120 CRV steel bits covering the most common screw types found in modern electronics: Phillips, Torx, Flat Head, Triwing, Hex, Pentalobe, Triangle, and others. This broad coverage ensures compatibility with a wide variety of devices.
- 19 Additional Repair Tools: Beyond the electric screwdriver, the kit includes specialized non-powered tools such as opening picks, spudgers, jimmy tools, tweezers, suction cups, flex extensions, magnetic mats, and more—each designed for specific disassembly and component-handling tasks.

Benefits & Use Cases
This electric screwdriver set shines in scenarios demanding both precision and reliability. Whether you’re upgrading your laptop’s SSD, repairing a cracked smartphone screen, servicing a drone motor, or maintaining gaming peripherals like controllers or headsets, its versatile bit collection and adjustable torque settings ensure safe and effective operation. The inclusion of non-powered tools such as spudgers, suction cups, and magnetic mats makes opening sealed enclosures straightforward and reduces the risk of damaging fragile parts. Home repair enthusiasts will appreciate the ability to perform detailed fixes without relying on expensive professional tools or services. IT support technicians can streamline device servicing, while hobbyists enjoy a trusted solution for custom builds, modifications, and routine maintenance. The auto-stop function adds critical protection when working near sensitive circuits or thin plastic housings where overtightening could cause irreversible damage.
Beyond standard repairs, this toolkit supports a wide range of applications including watch servicing, jewelry maintenance, model building, and even automotive dashboard panel removal. Its compact size and lightweight design make it easy to carry in a toolbox or keep in an emergency repair kit at home or on the go. The magnetic mat included helps organize bits and small screws, reducing the chance of losing tiny components during disassembly—a common issue when working with consumer electronics.
Important Notes
The package includes: 1 electric screwdriver unit, 1 manual precision screwdriver (useful for high-resistance or stripped screws), 120 precision bits, and 19 additional repair tools. The product has undergone 28 rigorous battery safety tests to ensure durability, reliability, and compliance with international standards. Note that this is not a powered impact driver or heavy-duty drill—its purpose is fine motorized screwdriving rather than structural fastening or metalworking. Always store the unit and accessories in a dry environment to preserve battery life and tool integrity. Not recommended for use on extremely hard materials or structural metalwork beyond typical electronic applications.

Extremely great value!
This is an electric screwdriver kit that comes with 120 bits I believe. There are bits in there for fasteners. I didn’t even know existed. It came to $33 with tax. You are able to adjust the torque on the electric screwdriver. It does not feel like a piece of garbage at all. I would have paid $33 just for the bits! Plus it comes with a manual screwdriver just in case the electric one is dead. Excellent product!

Great Set!
it works really well, very easy to use and can fit in all the paces you need with all the accessories. Torque is as expected with this sort of pencil drill, while not as powerful as a normal drill it will get everything you need done, and all the bits you get is amazing, it has everything you could ever need!

Excellent tool. Don’t waste your money on the 3-4x more expensive ones, this one works great.
This thing is awesome! Perfect addition for easy electronics repair. Great price for a surprisingly awesome quality. Ordering a second one for my mobile bag.

It’s fine
It’s alright, for the price I’m pleased overall. It had the parts I wanted, electric and regular screwdrivers, magnetizer, bit set, and magnetic screw pad. All in the same kit.Saying that the quality is not great, but I got what I paid for so not a major complaint. I did notice the driver has EXACTLY the same exterior as a $10 precision kit I bought in 2019 except for it had orange instead of grey. I did switch out the screwdriver (thicker extension shaft) and the flexible extender (it was just higher quality) from my old kit to new.Pleased overall, since I only use these kits a few times a year the cheaper kit is fine and for the quantity/quality I need these for this set is perfectly adequate (mostly PC building and part modification).

Not iFu, but really great for the low price.
I needed a nice, complete set, to throw in my “travel kit” for servicing small electronics.I have a few iFu sets and, they are very nice but don’t travel as well (the lids displace easily resulting in a pile of loose bits to rearrange).These kits fold up neatly and securely. The driver is not quite as good quality as the iFu driver but it’s very good, and I’ve had no issues with the set. The USB-C charging port is much easier to connect. The only thing I’d recommend to “top-off” this set would be a short, flexible ruler (I added to my set). I was surprised this kit didn’t include that.

A very nice little kit.
This kit has almost every bit I could need in my work on computers. The electric screwdriver is quiet and smooth. The adjustable torque is useful and practical. The charge port is USB-C which is convenient.The spudgers are good. The tweezers are cheap and a bit junky but I have tons of better tweezers anyway.

Don’t expect any torque
Great collection of heads and a decent, if underpowered, little mechanical screwdriver, but there is no torque to speak of in it. Be prepared to use the manual driver if anything has been tightened at all.
