those panels don't seem to be big enough to be directly powering much, so I think the answer would be that this would work in many light levels, but it will just charge the batteries slower in lower light situations.

Does it have to be in sun?

This looks to be a smart product!! Does this charger needs to be out in the sun (directly) in order to produce rated power, or can this produce rated power in normal day light in a room or even with artificial light in s room? The problem I see here is that I won't be able to charge my phone overnight, which I usually do.
