Abstract: A multi-socket power extension source includes a power inlet port, and power outlets coupled to the power inlet port through switches. The multi-socket power extension source includes a controller configured to control the switches. The controller is configured to repetitively determine if an estimate of a total current through the power inlet port exceeds a prescribed current limit. When the estimated total current exceeds the prescribed current limit, the controller is configured to identify the outlet having the largest current increase and turn off the switch coupled to that outlet. The controller is further configured to reconnect the surge outlet, when an updated estimated total current is less than the prescribed current limit by at least the current of the surge outlet, or after a prescribed reconnect time period. The multi-socket power extension source may be coupled to a secondary multi-socket power extension source in an expansion configuration.

Abstract: A method of refurbishing a handheld landscape power tool includes separating an original motor of the power tool from a tool head of the power tool. The tool head includes a tool shaft extending proximate to the original motor. A replacement power head and a shaft coupler are provided. The replacement power head includes a motor and a power shaft mechanically coupled to the motor. The shaft coupler includes a power shaft connecter coupled to a shaft-specific connecter. The replacement power head is coupled to the shaft coupler by connecting the power shaft connecter to the power shaft of the replacement power head. The tool head is coupled to the shaft coupler by connecting the shaft-specific connecter to the tool shaft of the tool head.
