Why does the solar panel output power not meet expectations when charging mobile devices?

Most devices charge slower as the battery fills up. Once it hits around 80%, they switch to a protective "trickle charge" mode. This limits power input, even with a powerful charger.

Can it store energy？

A solar panel is a conversion device that transforms light into electricity by absorbing sunlight as its energy source. It is not a power storage device. You need to unfold the solar panel under direct sunlight and connect it to your device.

Is it backpack-portable?

Of course! This solar panel is built for easy portability. Thin and compact, it slips easily into your backpack, making it a perfect on-the-go power source for hiking, camping, or travel.

Yes, it has an IP67 rating, which means it is splash-proof. However, the junction box is not waterproof, so please cover the junction box plug during rain to avoid water ingress.
