Portable solar charger designed using LM358N
This portable solar charger circuit electronic project is designed using some common electronic parts .
As you can see portable solar charger circuit, is based on a LM358N operational amplifier and one transistor.
This regulator provide a constant 2.4 volts DC and can be used for powering small devices that needs to be powered from two AA battery cells .
Because the regulator has a low drop down voltage of 0.3 volt you should take care about this when you choose solar cells .
Maximum load current for this solar charger electronic circuit project is around 125mA typically , enough for small portable devices like radios .
