You Should Buy 12V Instead of 20V

Battery voltage can be a tricky subject. What’s the real difference between 12V, 18V, and 20V Max tools? What about when the voltage goes even HIGHER? Reaching power levels of 36V, 60V, 80V, and even higher have become common practice in the power tool industry, in this episode of PTR Punchlist we discuss the differences between these battery platforms, which is best for who, and important topics like… He-Man.


Key Insights on Why You Should Buy 12V Instead of 20V…

  • 🔌 Many people gravitate towards 18-20 volt tools because they’re on sale and everywhere, but it takes maturity to realize the potential of smaller 12-volt tools.
  • 🔌 If you’re planning to step up your DIY game and get into cutting and more advanced tasks, then a 20V drill might be more suitable.
  • 🔋 20 volt max is NOT more powerful than 18 volt = Same cells in the battery.
  • 🔋 The marketing aspect of voltage labeling: “When you see these guys that are in marketing teams that are saying 20 more power, they really mean we have 20 more cells in the pack.”
  • ⚡️ Understanding the power equation: power equals current times voltage, and it’s a simple multiplication problem from there.
  • 🔌 Improved battery technology allows for more power draw without getting as hot, thanks to better heat dissipation and increased capacity.
  • 🌡️ Cooling technology in the 12V pack, like Flex’s individual cell wrapping, contributes to its extended runtime.
