Is it waterproof?

The SunPower panel part is IPX4 waterproof and other parts are not waterproof,  please do not immerse it in water

What does it mean when the red light constantly flashes red?

When there is overcurrent, short-circuit, the red light will flash

How many hours of sunlight to fully charge?

It depends on your devices and light intensity, please noted that solar chargers can't store the electricity

Can it charge a power bank?

Of course, our solar charger has 3 USB ports that support maximum 18V output, but please do not expose the power bank to direct sunlight because overheating of the power bank may cause it to fail to charge

Does the entire solar charger need to be placed in the sun to charge?

In fact, any solar panel can be charged by sunlight, but the smaller the area irradiated by the sun, the lower the charging efficiency, so we suggest to put all the solar panels under the sun, otherwise the solar panels may not be able to charge

Can this be used to charge a car battery in an emergency?

Of course not, 42W output power is not enough to charge the car battery
