The charge controller comes with overcharge protection.

Also smart auto-optimization charging. Auto-optimization technology detects when charging drops due to changes in light conditions. This can be due to shadows cast by trees, clouds, or other objects.

To prevent underperformance auto-optimization charging prevents undercharging due to these reduced levels.

When light improves charging will immediately return from the reduced level.

This is a vast improvement on delays in charging times of USB devices.

When you mount it on a back pack you reduce performance.

This is due to movement and thus poor positioning. Remember though that by doing so, you add much more charging time while hiking.
