Bar length first: 6-inch cuts 3-inch limbs, 8-inch cuts 4-inch storm wood. Then motor (800 W at 4700 r/min is the working standard), then battery count.
Two packs per yard session
What to check before you pay for a mini chainsaw.
Listings blur together because most minis share the same motor family. The differences that matter are bar length, chain tensioning, battery count and what is actually in the carton. Ten minutes here saves a return shipment.
Bar length decides everything
A saw cuts roughly half its bar length in one pass. Measure the thickest branch you cut in a normal month and buy that bar. The 6 vs 8-inch breakdown has the numbers.
