UnaMela Mini Electric Screwdriver Set 140-in-1

For electronics hobbyists, PC builders, and anyone who handles small repairs at home, the UnaMela Mini Electric Screwdriver Set combines a cordless driver with precision bits and tools for opening devices. Its range is aimed at compact screws in computers, laptops, cell phones, keyboards, game consoles, and RC projects—not general household fastening.

The kit also includes a manual precision screwdriver, so you can switch to hand control when a screw needs a gentler finish or more deliberate pressure.

Best use cases

This set makes sense for jobs where keeping the right bit and a small opening tool close by saves interruptions. You get 120 precision bits in Phillips, Torx, flat-head, Triwing, hex, Pentalobe, triangle, and other types, plus 19 repair tools for disassembly and maintenance. The listed applications include PCs, laptops, cell phones, MacBooks, RC cars, drones, keyboards, and game consoles.

Picture a small keyboard repair: use an opening pick to separate a panel, choose a matching bit, then use the electric driver for the small screws. If you need a slower, more controlled finish, the included manual driver gives you another approach. That flexibility is useful for delicate work, though the set’s focus on precision electronics means it isn’t a substitute for a higher-torque driver for larger fasteners.

Product specs

The electric screwdriver has five torque settings from 0.15 to 0.35 Nm and a stated top speed of 200 RPM. Four LED lights are listed in the product name. The pen-shaped design is intended for a light, balanced grip during detailed work, actual comfort will depend on your hand and how long you use it.

The cordless driver uses a 350mAh lithium-ion battery, charges through a Type-C interface, and is listed as taking 60 minutes to charge. The set includes the manual precision screwdriver, 120 CRV bits, and 19 repair tools, including an opening pick, fiber spudger, Jimmy, flexible extension, angled tweezers, suction cup, and magnetic mat. On the spec sheet, the torque range is the detail to weigh most carefully: these settings are geared toward small screws, not forceful fastening.

Where it shines

A powered driver can speed up repeated screw removal compared with turning every screw by hand, while the manual option helps when you want more direct control. That combination is the main appeal here: you don’t have to choose between an electric-only kit and a basic hand screwdriver set. The assortment of bit styles and opening tools also makes it more self-contained for common electronics repair tasks.

What matters more for your work: speed on small screws, or the ability to apply substantial force? Worth considering if you regularly open electronics and want one kit for bits, powered turning, and basic disassembly. It’s not for you if your projects mostly involve larger hardware, heavy fastening, or repairs that call for tools beyond the included precision accessories.

Buying verdict

This UnaMela kit is most compelling for someone who already does—or wants to start doing—small electronics repairs and would use both the electric driver and the included hand tools. The five torque settings, rechargeable cordless design, and broad bit selection give it a practical role at a PC or hobby workbench. For occasional repairs involving just one or two screw types, a simpler manual precision set may be enough, for demanding fastening, look for a tool built for higher torque. Check that the listed bit styles and torque range suit the devices you plan to work on before choosing it.
