what is the wattage output rate. is it higher then the other bags?

This backpack features 10 Watts of solar power and a 19,800mAh battery pack which can charge laptops and USB devices. This is the only solar backpack available that can charge laptops. We hope this helps!

can it charge a 17 inch asus laptop?

Yes it can charge a 17" asus laptop, though depending on the capacity of your specific laptop battery it may not recharge it from fully from 0-100% but get a majority of the way there instead. We recommend charging when it is asleep or turned off to charge more efficiently and quickly.

Not just the panel, is this backpack is 100% waterproof, because is pretty expensive, want to confirm it before buying it

The backpack is not 100% waterproof. The fabric has a waterproof backing, but eventually water will come in through the zips. Keep in mind that in addition to using high quality materials and construction throughout the backpack, there is also a rugged solar panel and 88 Watt hour battery pack.
