Amazon.ca: Litheli 8'' Electric Cordless Pole Saws - $39.99

Been waiting to buy this since Prime Day, and this is the lowest price I've ever seen. This pole saw comes with an 8-inch blade and an extendable pole that stretches from 7.7 ft to 11.5 ft. It also comes with a 20V/2.5Ah Li-ion battery, and the manufacturer claims it can make up to 50 cuts per charge. I bought their regular mini chainsaw on Prime Day for more, and it has worked perfectly. You will need to get some machine oil for lubrication, though. Their battery charges via USB-C. However, if you use a low-power USB port, such as one on an older computer, charging can take a very long time. If you use a higher-powered charger (around 50W), it can be fully charged in less than two hours.
