Review on 🎒 Durable Waterproof Large Laptop Backpack, 17.3 inch, Ideal for Travel, College, Business. USB Charging Port & Headset Port Included. Dark Gray, Men & Women's Bookbag by Brian Gordon

I like that I have plenty of room for things. I'm just frustrated that there isn't much information about the included charging cables. I assumed the backpack had a built in power supply. But you need to connect a power bank to it, and then you can charge your devices from the bank. Very uncomfortable. But at least I like the extra space. So I will only use it for that.
