Example Input: It is deceiving in that it did not come with the portable charger and cord as it advertises. We were thoroughly disappointed when the package came and that was missing. The whole point of my 10 year old son wanting the backpack was for that reason. That being said, if you like the backpack the. You will be happy. My son has been in school for 2 months and no damages from the backpack can be sighted.
