Can it charge a power station or laptop?

The listing shows only a 5V output, so it suits phones and small USB devices. A power station or laptop needs higher voltage and current, which this panel does not document.

Is the 100W rating realistic?

A 100W panel at 5V would need about 20A, which small folding panels rarely deliver. Expect output closer to a basic USB charger and check the panel's label when it arrives.

How big is it folded and open?

Folded it is about 6.5 by 4.1 by 0.6 inches; open it is about 17.3 by 6.5 inches. The brand notes 1–2 cm measurement tolerance.

What comes in the box?

One solar panel. The listing does not name a cable, adapter or carry case, so plan on supplying your own charging cable.

The listing does not state a water-resistance rating. Keep it dry and out of rain unless the panel itself is marked otherwise.

Our take on the Eston 100W Foldable Solar Panel

The Eston 100W Foldable Solar Panel is a portable PET-covered panel that folds down to roughly 6.5 by 4.1 inches and opens to about 17.3 by 6.5 inches. It is aimed at charging phones and small devices outdoors, in emergencies or on job sites. The listing gives a 100W rating but only a 5V output, which is far below what a 100W panel normally produces and points to a small USB-style charger rather than a panel for power stations. Treat the wattage claim with caution and compare it against folding panels from established solar brands that publish full voltage and current specs.
