#CMT# #/CMT# The circuit (P2) has at least two inputs (I1-I3) for connecting a recharger and an output (U1) for connecting to a power supply port for the device, via which the power for recharging the battery is received. Each input makes contact via a connection with a junction point (K) for the output. At least one of these connections includes a voltage converter (S1, S2) which converts a supplied power voltage into a common charge voltage for delivery to the output. #CMT# : #/CMT# An independent claim is also included for a casing for this circuit, which has a round shape, the output connection and connectors being located in a peripheral surface of this casing. #CMT#USE : #/CMT# For portable electronic devices with rechargeable batteries, e.g. mobile phones, PDA's, MP3 players, notebooks and laptop computers. #CMT#ADVANTAGE : #/CMT# The battery can be recharged using different power supply voltages without the risk of damage to the internal circuitry of the electronic device. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figure shows the circuit diagram. I1-I3 : inputs K : junction point P2 : battery recharging circuit S1, S2 : voltage controllers U1 : output. |
