You are comparing a 50ah vs 20 ah power tool combo kit to find the right balance of runtime and tool count. Both kits use 20V battery platforms and include cordless drill drivers and impact drivers. The main difference lies in the battery capacity and the number of tools included. The DEWALT kit offers a larger 5.0 Ah battery and three additional tools, while the CRAFTSMAN kit provides two smaller 2.0 Ah batteries and just two tools. This affects how long you can work before recharging.

- You prefer a lighter, more compact kit for easy storage and portability.
Verdict
Choose the DEWALT kit if you need a versatile set of five tools and longer runtime from a single 5.0 Ah battery. Pick the CRAFTSMAN kit if you only require a drill and impact driver and value having two batteries for quick swaps. Your choice depends on whether you prioritize tool variety and power or battery redundancy and simplicity.
5.0Ah vs 2.0Ah Kit Specs
Battery Capacity
Edge: DEWALT 20V MAX 5-Tool Combo Kit with 5.0 Ah Battery
The DEWALT kit includes a single 5.0 Ah battery, while the CRAFTSMAN kit provides two 2.0 Ah batteries. A higher amp-hour rating generally means more energy storage, allowing the tool to run longer between charges. The 5.0 Ah cell offers extended runtime for demanding tasks. The two 2.0 Ah cells allow for quick swaps if you carry spares. However, the total energy in the DEWALT battery is 5.0 watt-hours per cell, whereas the CRAFTSMAN total is 4.0 watt-hours across both. You get more continuous power from the larger single battery in the DEWALT setup.
Kit Size
Edge: DEWALT 20V MAX 5-Tool Combo Kit with 5.0 Ah Battery
Tool count is a major factor when choosing a combo kit. The DEWALT package is a 5-Tool kit. It includes a drill, impact driver, reciprocating saw, circular saw, and oscillating multi-tool. The CRAFTSMAN package is a 2-Tool kit. It only contains a drill driver and an impact driver. If you need multiple tool types for different jobs, the DEWALT kit provides significantly more variety. You get specialized tools like a circular saw and reciprocating saw included. The CRAFTSMAN kit is limited to basic drilling and fastening tasks. The DEWALT kit is more versatile for general home projects.
Motor Type
Edge: DEWALT 20V MAX 5-Tool Combo Kit with 5.0 Ah Battery
Motor efficiency affects runtime and power delivery. The DEWALT drill driver features a high-performance brushless motor. Brushless motors are generally more efficient than brushed ones, leading to longer battery life and less maintenance. The CRAFTSMAN drill driver lists power output in unit watts out but does not explicitly specify a brushless motor in the provided data. You should check the specific model details for the CRAFTSMAN motor type. Assuming standard brushed motors for entry-level kits, the DEWALT brushless motor offers better efficiency. This efficiency translates to more work per charge on the DEWALT tool.
Chuck Size
Edge: Tie
The drill driver chuck size determines the maximum bit or accessory diameter you can use. The CRAFTSMAN drill driver features a 1/2 inch chuck. This is the standard size for most drill bits and driving accessories. The DEWALT drill driver is listed as a 1/2 inch power drill driver in the features. Both kits use the same standard chuck size. This means you can use the same bits in either tool. There is no functional difference in accessory compatibility between the two chucks. Both support standard 1/2 inch drill bits and drivers.
Weight
Edge: CRAFTSMAN V20 Drill and Impact Driver Kit
Portability matters for overhead work or carrying tools to different sites. The DEWALT 5-Tool kit weighs 21.4 pounds. This includes the tools, the large battery, and the charger. The CRAFTSMAN 2-Tool kit weighs 8.2 pounds. This includes the two tools, two batteries, and the charger. The CRAFTSMAN kit is significantly lighter. It is easier to carry in a bag or lift above your head. The DEWALT kit is heavier due to the additional tools and the larger battery. If you only need two tools, the CRAFTSMAN kit is much more portable.

Frequently asked questions
Does a 5.0Ah battery last longer than a 2.0Ah battery?
Yes. A 5.0Ah battery holds more energy than a 2.0Ah battery. This higher capacity allows tools to run for extended periods before needing a recharge. You get more continuous runtime for demanding tasks with the larger battery.
Which kit includes more tools in the box?
The DEWALT kit includes five tools. It comes with an impact driver, circular saw, reciprocating saw, and oscillating multi-tool. The CRAFTSMAN kit only includes two tools, specifically a drill driver and an impact driver.
Are both kits compatible with the same battery platform?
Yes. Both the DEWALT and CRAFTSMAN kits operate on a 20V power source. This means they share the same voltage platform. You can use batteries from either brand if they fit the specific tool chuck or slot.
Which kit is heavier and bulkier to carry?
The DEWALT kit is significantly heavier. It weighs 21.4 pounds and measures 18.4 inches in length. The CRAFTSMAN kit is lighter at 8.2 pounds and more compact. The larger tool count and battery drive the weight difference.
Can I use a 5.0Ah battery in the CRAFTSMAN tools?
Likely, but check the specific model. Both kits use a 20V platform. If the CRAFTSMAN tools accept standard 20V batteries, a 5.0Ah battery from another kit might fit. However, the DEWALT kit includes its own dedicated 5.0Ah battery.
Is the 2.0Ah battery enough for light home projects?
It can be sufficient for light tasks. The CRAFTSMAN kit provides two 2.0Ah batteries. This offers redundancy if one battery dies. For simple drilling or driving, the smaller capacity may still provide adequate runtime.
What is the difference in included tool variety?
The DEWALT kit offers greater variety. It includes specialized tools like a circular saw and reciprocating saw. The CRAFTSMAN kit focuses on basic fastening with just a drill and impact driver. Choose DEWALT for more tool types.
