Solar charger can work without sunshine?
 

Solar charger[/b] is convenient for people who usually travel out. But sometimes I want to ask such question “solar charger can work without sunshine?” Perhaps it is a stupid question. But I still want to know the answer. And if they can not work, is it still convenient. You can not use inside and you can not use in winter. Only without sunshine, it becomes rubbish. So is it worth for us to use?

Solar charger will not work without sunshine. That being said cloud cover does not stop the sun. Might lessen it's affect, but not stop it. As forcedinjection said good for trickle charging
