Electric chainsaws are chainsaws that are powered by electricity rather than gasoline. They typically have an electric motor that drives the chain and are connected to a power source through a cord or a battery pack. Electric chainsaws are typically quieter and easier to maintain than gas-powered chainsaws, making them a popular choice for homeowners and those who need to perform light to medium-duty cutting tasks, such as pruning trees or cutting firewood. However, they may not be as powerful as gas-powered chainsaws and their range of use can be limited by the length of the cord or battery life.

Electric chainsaw as garden tool has many safety features:

1. Chain Brake: This feature stops the chain from rotating when the saw encounters sudden resistance, such as kickback or when hitting a hard object.

2. Handguard: This protects your hands from being cut by the chainsaw chain and also helps to keep debris away from you.

3. Trigger Lock: This is a safety mechanism that prevents the accidental starting of the chainsaw.

4. Anti-vibration System: This reduces the amount of vibration from the saw, making it more comfortable to use and reducing the risk of fatigue or injury.

5. Throttle Trigger Interlock: This feature prevents the saw from starting unless the throttle trigger is engaged.

6. Automatic Oiler: This keeps the chain lubricated and reduces the risk of overheating, which can lead to dangerous situations.
