Dewalt FlexVolt vs. 20V: Which Is Better? - WoodworkingToolsHQ (2024)

When it comes to power tools, Dewalt is a name that stands out in the crowd. They’re known for producing high-quality tools that can handle tough jobs with ease.

Two popular Dewalt battery platforms are the FlexVolt and the 20V. But which one is better for your needs?

Here’s a comparison table summarizing the key differences between Dewalt FlexVolt and Dewalt 20V systems:

1. Voltage: The Core Distinction

The most significant difference between Dewalt’s FlexVolt and 20V systems is, you guessed it, the voltage. This distinction can be summed up like this:

• FlexVolt: It’s a flexible voltage system that can switch between 20V and 60V. This means you can use the same battery for various tools, making it versatile and cost-effective.
• 20V: This is a standard voltage system. Each tool in the 20V lineup operates at a fixed 20V, which is still plenty of power for most tasks but lacks the versatility of the FlexVolt.

Example: Suppose you have a FlexVolt battery. You can use it with a 20V drill for everyday tasks and then switch it to 60V to power a heavy-duty table saw when needed. With a 20V battery, you’d need separate batteries for each tool.

2. Compatibility: One Battery, Many Tools

Flexibility in tool compatibility is a significant advantage of the FlexVolt system.

• FlexVolt: This system is backward compatible with 20V tools, which means if you have FlexVolt batteries, they’ll work with your existing 20V Dewalt tools.
• 20V: Batteries in the 20V system are generally not compatible with FlexVolt tools due to the voltage difference. You’d need separate batteries for your FlexVolt tools.

Example: Let’s say you have a FlexVolt circular saw and a 20V drill. The same FlexVolt battery can power both tools, saving you money and reducing clutter in your tool collection.

3. Power and Runtime: Flexibility vs. Specialization

• FlexVolt: It offers the advantage of variable voltage, providing both power and runtime flexibility. You can use a 20V setting for longer battery life or switch to 60V for maximum power.

• 20V: While 20V tools are no slouch, they are generally more specialized. They provide consistent power but may not match the raw strength of a FlexVolt tool at 60V.

Example: If you’re framing a house, you’d want the FlexVolt saw for its high voltage. But for simple tasks like screwing in screws, the 20V drill might suffice.

4. Cost Consideration: Initial Investment vs. Long-Term Savings

• FlexVolt: It might require a higher initial investment due to the dual voltage technology and compatible tools. However, in the long run, it can save you money by reducing the need for multiple batteries and chargers.

• 20V: The 20V system is generally more budget-friendly initially, but you might end up spending more on additional batteries and chargers if you expand your tool collection.

Example: If you’re a professional contractor with a wide range of tools, the FlexVolt system can provide significant cost savings over time.

5. Weight and Size: Portability Matters

• FlexVolt: FlexVolt batteries are typically larger and heavier due to their dual-voltage capability. This might affect the overall portability of your tools.

• 20V: 20V batteries are smaller and lighter, making tools more manageable and convenient, especially for extended use.

Example: If you’re working on projects that require a lot of mobility, the 20V tools might be more comfortable to use throughout the day.

6. Specialty Tools: Tailored to Your Tasks

When it comes to specialty tools, the choice between FlexVolt and 20V can be crucial.

• FlexVolt: If you need heavy-duty tools like a FlexVolt miter saw for precise cuts, the FlexVolt system’s high voltage will deliver superior performance.
• 20V: For specialized tools that don’t require extreme power, the 20V lineup has a variety of options that are more compact and budget-friendly.

Example: If you’re a woodworker who needs precision and power for intricate cuts, a FlexVolt miter saw might be your best friend. But for simple woodworking tasks, a 20V jigsaw could be sufficient.

7. DIY Enthusiasts vs. Pros: Who Benefits More?

Consider your skill level and how often you’ll be using these tools.

• FlexVolt: Professionals who use their tools extensively may appreciate the versatility and long-term savings of the FlexVolt system.
• 20V: DIY enthusiasts or occasional users might find the 20V system more cost-effective and easier to handle.

Example: If you’re a weekend warrior who tackles small projects occasionally, the 20V lineup might suit you perfectly without breaking the bank.

8. Charging Time: Patience vs. Efficiency

Battery charging time can be a game-changer, especially for time-sensitive projects.

• FlexVolt: Due to its higher capacity, a FlexVolt battery may take longer to charge compared to a 20V battery. This can be a downside if you need quick turnarounds.
• 20V: 20V batteries typically charge faster, so you can get back to work sooner.

Example: If you’re a contractor with tight project deadlines, a 20V system might help you maintain efficiency by reducing downtime.

9. Tool Availability: Assess Your Project Needs

Before making a decision, evaluate the availability of tools in each system.

• FlexVolt: While the FlexVolt system offers fantastic flexibility, not all Dewalt tools are available in FlexVolt versions. Be sure the tools you need are compatible before committing.
• 20V: The 20V lineup is extensive and covers a wide range of tools, making it easier to find the right tool for your project.

Example: If you have specific tools in mind that you must have for your work, check if they are available in FlexVolt or if you need to opt for the 20V version.

10. Future-Proofing Your Investment

Consider the future of your tool collection and the potential for expanding it.

• FlexVolt: If you plan to grow your collection over time, the FlexVolt system’s versatility will serve you well by accommodating new tools.
• 20V: While the 20V system is excellent for its specific tools, it may limit your options if you decide to diversify your toolkit down the road.

Example: If you’re just starting, the 20V system might be a good entry point. But if you see yourself expanding your toolbox over time, the FlexVolt system could be a smarter long-term investment.
