MXMZHXU Mini Electric Screwdriver, 3.7V, 78-in-1

The MXMZHXU mini electric screwdriver is presented as a 3.7V, 78-in-1 precision kit for small electronics repairs. Its claimed 72 magnetic bits and adjustable electric torque suit fine screws, but customer feedback raises concerns about usable strength, so it is best considered for light-duty work rather than stubborn fasteners.

Pros and cons

Pros

A broad claimed selection of 72 bits may cover a range of small electronics fasteners.
Magnetic bit holding and storage are described for keeping bits organised during repairs.
The separate manual mode gives a stated higher torque option than the electric maximum.

Cons

Customer feedback reports mixed strength and concerns about very little torque, which may limit the tool on tight screws.

What to know before buying

Listing details to confirm

Listing details are inconsistent: the title calls the kit 78-in-1 with 72 magnetic bits, while the item details give a set name of 78-in-1 and a number of items of 72. The stated electric maximum is 0.5N.m, but the feature text also claims a 3 N.m manual mode. Treat the claimed over-500-screw runtime as a stated test claim, not a guaranteed result. The listed dimensions include the case or tool unspecified.

Who is it for?

A good fit for

People doing occasional, light-duty repairs on phones, glasses, watches or computer components.
Buyers who want a small repair kit with many bit types and magnetic storage.

Less suited to

Users who regularly face tight, seized or larger fasteners and need clearly dependable higher electric torque.
Buyers who require a verified runtime or independently confirmed performance.

Customer feedback describes the kit as handy and reports positive impressions of quality and convenience, but strength is mixed and several customers raise concerns about limited torque. That matters because the listing's electric maximum is 0.5N.m and its stated applications centre on small electronics. The generally favourable aggregate ratings sit alongside a notable range of low ratings, so feedback does not establish that every unit will provide dependable driving force.

Positive themes

Customers describe the kit as handy and report positive impressions of quality and convenience.

Negative themes

Some customer feedback reports very little torque and insufficient strength for driving screws.

Mixed feedback

Strength receives mixed feedback.

Frequently asked questions

How much torque does the screwdriver provide?

The listing states an electric maximum of 0.5N.m and five electric torque modes, with a separate 3 N.m manual mode. Customer feedback includes concerns about low torque, so do not assume it will handle tight screws reliably.

How many bits are included?

The title and feature text claim 72 magnetic bits. The item details list 72 items, although the set name is 78-in-1, so the overall count is not clearly reconciled.

What charging and battery details are listed?

The listing specifies a 350mAh battery and Type-C charging. It also claims over 500 M2.5x5mm screws per charge, which is a manufacturer claim rather than a guaranteed runtime.

What repairs is it intended for?

The listing names computers, phones, glasses and watches. Given the reported concerns about strength and torque, it is more suited to light precision tasks than stubborn fasteners.
