GrenPRO 4V Cordless Screwdriver

This 4V cordless electric screwdriver targets DIY enthusiasts and homeowners handling furniture assembly, toy repair and cabinet fixing. The kit includes 51 magnetic bits and a carrying case for organised, grab-and-go convenience. It is not suited for heavy construction, high-torque fastening or users needing drill functionality.

Quick-Lock Chuck and USB-C Charging

The quick-lock chuck allows rapid bit changes without extra tools, while the 850mAh lithium-ion battery charges via USB/Type-C from laptops or power banks. Intuitive left/right rotation markings reduce direction errors. A common issue is forgetting to charge before a job since batteries are not pre-installed.

220 rpm Speed and Lightweight Limits

Maximum speed of 220 rpm limits the tool to light-duty screwdriving rather than drilling or dense materials. At 170 grams the driver reaches tight spots easily, but the low torque and fixed speed restrict use on large screws or hard woods. The built-in LED assists in dim areas but does not replace task lighting.

Questions about this item

How can I verify the GrenPRO-071904 is working correctly after first use?

Confirm the LED illuminates when the trigger is pressed, the chuck spins at 220 rpm in both left and right directions, and the 850mAh battery holds charge through several fastening tasks.

What comes in the box with the GrenPRO-071904 and what must I purchase separately?

The set includes the 4V screwdriver, 51 magnetic bits and a carrying case; no battery is included in the package, so the internal 850mAh lithium-ion cell must be charged via USB/Type-C before first use.

Which version of the GrenPRO-071904 should I choose for everyday home repairs?

The single listed model GrenPRO-071904 delivers 220 rpm, weighs 170 g and supplies 51 bits in one case, making it the only configuration available for general DIY tasks.
