DeWalt 20V MAX: the most versatile cordless ecosystem
DeWalt's 20V MAX system is the benchmark for reasons that go beyond individual tool performance. With over 200 compatible tools, your initial battery investment applies to everything from drills to outdoor equipment to vacuums. The FLEXVOLT adapter lets compatible tools run on either 20V or 60V batteries, future-proofing your collection.

Milwaukee M18: the professional contractor's choice
Milwaukee's M18 system matches DeWalt in raw tool performance and its FUEL line of brushless tools is particularly impressive. The Red Link Plus intelligence system protects both the battery and the motor from damage, which translates to notably longer tool life on demanding jobsites. The system costs slightly more than DeWalt but the build quality and durability are exceptional.
What matters most
Battery voltage
20V (or 18V in other brands) handles the majority of household and professional tasks. For heavy-duty cutting or large saws, 60V or 80V platforms provide significantly more power.
Brushless motor
The single most valuable upgrade in cordless tools. Brushless motors run cooler, more efficiently, and longer than brushed motors. Look for brushless in any tool you use heavily.
Ecosystem compatibility
Check how many tools are compatible with the battery platform you are entering. A deeper ecosystem means more future purchasing flexibility and less battery duplication.
Battery capacity (Ah)
Higher amp-hour batteries run longer per charge. A 5.0Ah battery runs about 2.5 times longer than a 2.0Ah battery of the same voltage.
Charger speed
Fast chargers can restore a depleted battery in 30 to 45 minutes rather than the standard 90 minutes. If you depend on tools for work, fast charging is worth the investment.
Frequently asked
DeWalt and Milwaukee lead for professional use. Ryobi offers the widest tool selection at lower prices for homeowners. Makita is also excellent for tradespeople.
Start with a kit that includes a drill, driver, and two batteries. Add individual tools from the same platform as your needs grow to share batteries.
Most Li-ion batteries last 3 to 5 years with regular use before capacity noticeably degrades. Avoid leaving them fully discharged or in extreme temperatures.
Yes. Brushless motors run cooler, last longer, and use battery power more efficiently than brushed motors. The longer tool life usually justifies the price premium.
