Naukay Extra Large Backpack, Travel Laptop Backpack 17.3 Inch Anti Theft Water Resistant Business Backpack Carry On Backpack with USB Charging Port, TSA Durable Backpack for Men Women, Black

I wanted to like this item, I loved the idea of a handsome looking laptop backpack with a charging port on the side. However, I tested using this side port with my powerbank inside using the USB provided by the backpack. It only charged 5% of my battery in one hour on my iphone pro max 13. I tried the same cord same powerbank, without using the USB from the backpack and directly plugged in, and it did 16% in one hour. That means this connection is 3x slower. It makes the feature almost not worth it, despite it being located conveniently on the outside of the backpack. The color is nice, and so is the design aesthetically, but the inside pockets feel as though they are made of a cheap and thing plastic material, so I have doubts as to how well the material would hold up over time. The section that holds the laptop is much more sturdier however though, so no concerns there. but the inside pocket material feels a little flimsy, like if you put something with a sharp point in it, like a compass or a pencil, or even a ballpoint pen without a cap, it might pierce the pocket. I would use it since I have it, but I probably wont be using the usb port which for me was my favorite function about it because of its speed. And I would not buy it again. Maybe you guys out there will think different.
