Black+Decker 20V MAX 10" Chainsaw Kit vs Sun Joe 24V iONMAX 10" Chainsaw Kit
Tinted cells mark the better figure on that row alone: more engine, longer bar, lighter, cheaper. A lighter weight is only a win on the same basis.
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
Sun Joe 24V iONMAX 10" Chainsaw Kit
- 4.0Ah pack is double what most 10-inch kits include
- Under two hours to a full charge
- Sun Joe publishes a real maximum cut diameter and a recommended one, which most brands do not
- Brushless 600W motor at a $130 sale price
- Replacement bar is a $15 stock part shared with Sun Joe's pole saws
- 9.3 lb for a 10-inch bar — three pounds over Worx's equivalent
- Sun Joe publishes no chain pitch or gauge, so sourcing loops means matching the bar part number
- 24V nominal is really 21.6V under load, and it shows in dense wood
- 2-year warranty, the shortest in this group
- The $130 price is a sale against a $179.99 list, so it will not always be there
