What owners like and complain about

Black+Decker 20V MAX 10" Chainsaw Kit

  • Cheapest entry to a full-size-handle battery chainsaw from a national brand
  • Shares 20V POWERCONNECT packs with the rest of B+D's cordless line
  • Tool-free chain tensioning
  • Tool-only LCS1020B exists at $109 for owners with packs
  • Sold and warrantied direct by B+D
  • One 2.0Ah pack is the whole energy budget — plan on a second battery, not a longer session
  • 9.1 lb listed for only 8 inches of cut is a poor weight-to-capability trade
  • Brushed motor, so it gives up runtime and power to brushless saws at the same price
  • B+D does not state whether its weight figure includes the battery
  • No bar options — 10 inches is all it will ever be

Black+Decker 40V MAX 12" Chainsaw Kit

  • Chain and bar interchange with DeWalt DCCS620 and Craftsman CMCCS620, so loops are everywhere
  • 60-plus 4x4 cuts per charge is a published, checkable figure — rare in this price class
  • Automatic bar-and-chain oiling and tool-free tensioning
  • 40V gives it noticeably more bite than B+D's 20V 10-inch saw
  • Complete kit at $199 with no separate battery purchase
  • B+D's 40V MAX line has few other tools, so the pack is close to single-purpose
  • 11.1 lb listed is heavy for a 12-inch bar; several brushless 14-inch saws weigh less
  • Brushed motor and a single 2.0Ah pack cap sustained cutting
  • No tool-only SKU sold on B+D's own site, so owners cannot buy just the saw
  • B+D does not state whether the listed weight includes the battery
