Powerful 2-in-1 Cordless Pole Saw with Extended Reach & DeWalt Battery Compatibility
Style: 4.0ah Battery Included, Style: 4.0ah Battery Included
This 2-in-1 electric pole saw is a solid choice for anyone who needs a convenient and powerful tool for yard work. The compatibility with DeWalt 20V MAX Battery is a big plus, especially if you already own other DeWalt tools—it saves money and makes charging simple.
The 10-inch cordless chainsaw cuts through branches smoothly and efficiently, making tree trimming quick and less tiring. The extension pole, reaching up to 14.5 feet, is a standout feature—it lets you tackle high branches without needing a ladder, which feels much safer.

Weak battery base on saw module.
Style: 4.0ah Battery Included
Probably would work for light duty. I used this thing less than 8 hours (less than a single day of work) and the saw broke at the base that it connects to the extension pole.
The motor on the saw itself seemed powerful enough. It got hung up in a branch and then broke on one side of the battery slide in (which was connected to the pole extension, as per the saw's design)
Probably buy a more durable one if you're really planning on doing some work with it. Bet it was made for city people.
