Where reviewers disagree Single-source only, so no cross-source comparison is possible. Pro Tool Reviews reported no physically measured benchmarks for the 8240 (its 12V, 2.0Ah and 35,000/5,000 RPM figures are manufacturer specs), so runtime and power claims remain unverified by any whitelisted tester.
