摘要
A unitary portable flashlight assembly incorporating a hand operated generator and rechargeable batteries, such as the pressure vented nickel- cadmium type with welded electrodes. The generator is designed and operated to charge th batteries at a high rate for a short time to provide extended operation of the load during a later discharging mode. The batteries also serve to regulate the voltage during the charging mode thus protecting the load if it be connected during the charging period. The battery assembly can provide the necessary energy to operate such devices as radio receivers and transmitters, electric fire starters, etc., as well as providing a mechanical output.
