Context, not marks against it, and our read of the data, not a lab test.
Overview
At 5.76 ounces, the Electric PSD S1 ACE is strikingly light for a battery-powered screwdriver. It runs on 4 volts and tops out at 250 RPM, which places it in the precision end of the power screwdriver spectrum. The $15.76 price point, combined with 308 reviews at 4.5 stars, makes it one of the stronger value propositions in its category.
The 200-unit monthly sales figure is the highest in this batch alongside a few other models, confirming real active demand rather than a one-off spike. Buyers consistently choose the PSD S1 ACE when they need something genuinely compact and easy to handle for detailed work, rather than a general-purpose fastening tool.
The 250 RPM speed is slightly faster than several 200-RPM competitors in this segment, giving a modest advantage in driving speed without sacrificing control. For the price and weight, this is a standout option in the budget compact screwdriver category.

- At $15.76, it is one of the lowest-priced options in the category with solid owner feedback
- Battery-powered design removes cord clutter for quick, targeted use
Cons
- 4V output limits torque for larger or longer fasteners
- No published amperage or battery capacity information to estimate runtime
- Light weight may translate to a shorter-lived build under heavy daily use

Performance notes
The Electric PSD S1 ACE runs at 4 volts with a 250 RPM no-load speed and tips the scale at just 5.76 ounces. The combination of low voltage and light weight targets precision tasks: electronics, hinges, flat-pack furniture, and similar light-duty applications. At this voltage, sustained heavy fastening is not the primary use case. The battery-powered setup is fully portable with no cord.
What buyers say
Owners overwhelmingly praise the ultra-light feel and the usefulness for electronics and household repair tasks. The $15.76 price relative to the 4.5-star performance consistently earns positive mentions. A minority of reviewers note they wished for slightly more torque when working with dense materials or longer screws.

Frequently asked questions
How does the Electric PSD S1 ACE compare to heavier compact screwdrivers?
At 5.76 ounces, it is significantly lighter than tools like the Hi-Spec DT02019 at 0.8 kilograms. For precision tasks the weight advantage is real, but heavier tools may offer more torque.
Is 250 RPM fast enough for furniture assembly?
Based on the specs, 250 RPM is adequate for most flat-pack furniture fasteners and small to medium wood screws. It handles standard assembly work at a reasonable pace.
