What owners like and complain about

Kobalt 80V 18" Chainsaw Kit

  • Ships a 5.0Ah battery at $299, larger than almost anything at the price
  • Claimed 300 cuts of 4x4 per charge is the longest runtime in the big-box battery tier
  • Inertia-activated chain brake, not just a hand-guard mechanism
  • 5-year tool warranty beats Greenworks, Craftsman and most of the field
  • On-board tool storage and an auto oiler come standard
  • 16.9 lb with the battery — heaviest 18-inch battery saw here, and punishing overhead
  • Kobalt has no manufacturer website, so specs, parts and support all run through Lowe's
  • 80V Kobalt packs fit only Kobalt tools, a much smaller range than Ryobi or Greenworks
  • Resale and parts availability depend entirely on Lowe's continuing to stock the platform

Kobalt 80V 16" Chainsaw Kit

  • Frequently $199 complete with battery and charger against a $299 list
  • Metal wrap-around handle rather than the all-plastic shells common at this price
  • Electronic chain brake and quick-adjust tensioning
  • 110 cuts from only a 2.0Ah pack — the bigger 80V Kobalt batteries extend it a long way
  • 12 m/s chain speed is the slowest in the 16-inch battery class by a wide margin
  • 15 lb with a small 2.0Ah battery is heavy for a 16-inch saw
  • 2.0Ah pack is the minimum viable size; a spare is a near-certain purchase
  • No manufacturer site — specs and support exist only on the Lowe's listing
  • List price swings by $100 between promotions, so timing matters more than usual
