The X-Dragon 40 is relatively large for a solar panel in this range. This panel would be ideal for people who want to charge a large battery that can support a bigger laptop.
Since this panel has twice the surface area of a regular solar panel it can capture more sunlight to charge up quicker. Even if a part of the panel was shaded due to cloudy weather, the rest of the PV cells would still get enough sunlight, to continue charging.
The charging unit has a built-in smart IC chip. This chip can automatically adjust the current and voltage output to give you ideal 2.8A current under direct sunlight.
