Craftsman Cordless Screwdriver Power Solutions and Compatible Battery Options
Maintaining older cordless tools often requires finding specific power supplies or compatible battery replacements. For owners of legacy Craftsman 7.2V pivoting screwdrivers, power restoration usually involves utilizing dedicated AC adapters rather than replacing internal cells. Modern users looking for current technology might instead consider the shift toward integrated USB-rechargeable electric screwdriver kits, which eliminate the need for specialized charging bricks. Meanwhile, those invested in the wider Craftsman ecosystem have access to the high-performance V20 brushless platform. This guide evaluates various power solutions and tool kits available for different project requirements, ensuring you choose the correct hardware for your specific model and application needs.
Selecting the right power source depends heavily on whether you are reviving a vintage tool or upgrading to current battery technology. While some replacement batteries cater to specific voltage requirements, others provide modern alternatives for broader tool compatibility. Understanding the distinctions between 7.2V charging adapters, 4V precision kits, and 20V brushless systems helps prevent hardware damage. This overview outlines the features of available power accessories and complete tool sets, focusing on the specific voltage and compatibility details provided by the manufacturers to help you make an informed decision for your workshop.

How to choose
Voltage Compatibility
When selecting power for your Craftsman cordless screwdriver, voltage matching is essential. The BestCH 9V AC adapter is specifically listed to support 7.2V DC Craftsman models like 937.111620 and 973.111620. Ensure your specific model number aligns with the adapter specifications to prevent damage. Mixing voltages between batteries or chargers and tools can lead to improper charging or failure to operate. Always verify the DC input requirements printed on your tool housing or original manual before purchasing a replacement power supply or battery component to ensure safe and reliable electrical compatibility.
Battery Chemistry and Maintenance
Understanding battery chemistry is vital for long-term performance. Replacement options like the CREABEST 3.6V Ni-MH batteries for Versapak systems highlight the importance of matching battery types to your tool's original design. Ni-MH batteries offer specific discharge characteristics compared to modern lithium-ion counterparts found in current Craftsman V20 tools. When maintaining older 7.2V cordless equipment, using the correct charger, such as the BestCH Class 2 transformer, helps preserve the internal cells. Always check if your tool requires a specific charging base or if an adapter is sufficient to maintain your equipment's operational life.
Integrated vs. Replaceable Batteries
Modern cordless screwdrivers like the Craftsman CMHT66720 feature integrated 4V lithium-ion technology with USB charging, which differs significantly from older 7.2V systems. If you prioritize portability and ease of use, a USB-compatible kit with an included charging base reduces the need for external power supplies. Conversely, if you own legacy 7.2V tools, you are likely looking for specific adapters or compatible battery packs. Evaluate whether your workflow benefits more from the convenience of a modern 4V precision set or the higher voltage output provided by traditional 7.2V cordless screwdriver platforms.
Tool Versatility and Features
Beyond power, consider the functional features included with your cordless driver. The Craftsman V20 brushless drill/driver offers a variable speed trigger and built-in LED, which are distinct from the precision focus of 4V screwdriver kits. For light-duty tasks, a pivoting 7.2V screwdriver provides ergonomic advantages in tight spaces. When choosing between a 4V precision kit and a V20 brushless tool, consider the torque requirements of your projects. Precision drivers excel at small screws, while brushless V20 models provide the power necessary for more demanding drilling or driving tasks in various workshop materials.
System Scalability
Investing in a tool platform influences your future equipment needs. Current Craftsman V20 tools utilize a shared battery and charger system, simplifying maintenance compared to older 7.2V tools that may require specific, hard-to-find adapters like the BestCH 9V transformer. If you are struggling to find parts for a legacy 7.2V cordless screwdriver, it may be more cost-effective to transition to a modern, supported ecosystem. Evaluate if your current tool's utility justifies the search for niche replacement parts or if upgrading to a contemporary brushless model provides better long-term reliability and easier access to batteries.
Frequently asked questions
Can I use a 7.2V battery with my 4V Craftsman screwdriver?
No, you should not interchange batteries between different voltage platforms. The Craftsman 4V precision screwdriver is designed for its specific internal battery system and USB charging, while 7.2V tools require specific power supplies like the BestCH 9V adapter. Using an incorrect voltage can cause permanent damage to the tool's motor and internal electronics. Always use the charging method or battery type specifically recommended by the manufacturer for your model number.
What is the best way to power my 937.111620 Craftsman screwdriver?
The BestCH 9V AC adapter is designed for the 937.111620 and 973.111620 Craftsman 7.2V cordless pivoting drill/drivers. This Class 2 transformer acts as the power supply for these specific legacy models. Ensure your tool's model number exactly matches those listed on the adapter to guarantee the correct DC input. This adapter serves as a replacement for the original power source, allowing you to maintain functionality for these older cordless tools.
Are the CREABEST 3.6V batteries compatible with my Craftsman 7.2V tool?
No, the CREABEST batteries are specifically designed as replacements for Black & Decker Versapak systems. They are not compatible with Craftsman 7.2V cordless screwdrivers. Each tool platform utilizes unique battery configurations and physical dimensions. Installing an incompatible battery can result in a poor fit, electrical hazards, or complete tool failure. Always confirm the battery model or chemistry matches the exact requirements specified in your Craftsman tool's user manual.
Does the Craftsman V20 drill use the same batteries as the 4V screwdriver?
No, the Craftsman V20 brushless drill/driver and the 4V precision screwdriver utilize completely different power systems. The V20 series uses a larger, high-capacity slide-on battery pack designed for more demanding applications, whereas the 4V screwdriver is a compact, USB-rechargeable tool. These two systems are not cross-compatible in terms of batteries or charging equipment. Each tool must be charged using its dedicated, proprietary charging solution provided with the kit.
How do I know if my Craftsman tool needs a new battery or charger?
If your cordless tool fails to hold a charge or will not run, first verify that the charger is functioning correctly. For legacy 7.2V tools, ensure the BestCH 9V adapter is securely connected and receiving power. For modern kits like the V20 or 4V screwdriver, check the charging indicators. If the tool still does not operate after a full charge cycle, the battery cells may have reached the end of their service life.
Bottom line
For users aiming to maintain legacy 7.2V Craftsman equipment, the BestCH 9V AC adapter is the most direct solution, specifically engineered for models like the 937.111620 and 973.111620. It bridges the gap between older hardware and modern power availability. However, if your goal is reliable, daily performance, the Craftsman V20 Brushless RP Compact Drill/Driver (CMCD714D1) stands out as the superior choice due to its modern brushless technology, integrated LED, and supported battery ecosystem. While the 4V precision kit (CMHT66720) is excellent for delicate electronics, the V20 platform provides the most robust and future-proof investment for general workshop tasks, far outpacing the utility of aging 7.2V tools that require specific, hard-to-source adapters.
Deciding between these options depends on your current inventory. If you possess a functional 7.2V screwdriver, the BestCH adapter is the most economical way to keep it running. If you are struggling with dead batteries for older tools, consider that the cost of adapters or replacement packs for obsolete systems often nears the price of a new, modern kit. For the best long-term value, prioritize the V20 brushless system if you need heavy-duty capability, or the 4V precision kit if your work is limited to light-duty assembly. Moving to a current, supported platform eliminates the frustration of searching for proprietary parts for discontinued 7.2V tools.
