How long do cordless leaf blowers actually run per charge?

Real-world runtime is dramatically shorter than spec-sheet claims because most listed times are at the lowest speed. Subreddit reports for EGO 2.5Ah batteries cluster around 15 minutes on turbo, while the Husqvarna 350iB's 7.5Ah pack lasts substantially longer per landscaping community reports. Plan on owning at least two batteries if you have more than a small lot.
