Bosch Tool introduced its Power Ready Wireless Charging System to charge cordless tools virtually anywhere, such as in a moving vehicle and between jobs or tasks with the battery on or off the tool.

“This is a game-changer," product manager Hagen Dost said in a statement. "Our new 18-volt wireless charging system eliminates the need for a bin of batteries with a partial charge. Now pros can easily charge their hand-held power tools in between tasks or jobs and not worry about dead batteries. This means increased productivity and increased profits.”

The product is based on the concept of contactless energy transfer, also known as inductive charging, according to the company. When the charger is plugged in and the compatible battery is placed on it, the charger begins wirelessly transmitting an alternating magnetic field. The battery, featuring an internal copper coil, acts as a receiver. As the alternating magnetic field penetrates the coil, voltage is induced and a charging current flows to the cells until full.
