CO.alition Colfax PHD Smart Backpack with Integrated Power Supply and 500GB Wireless Hard Drive

Just before I decided on the bag, I called the company to find out what this backpack was all about. It is interesting how they put so much thought into the construction and utilization of this bag. I also let the young lady know that if the bag had more colors (pink, red, blue...) instead of just black and charcoal grey, I would have gotten it for myself sooner. I purchased this for my grandson who was on his way to college. I found it at really great starting price; My inspection of this backpack was no less than intriguging; along with the obvious compartments for larger items like Laptop, Tablet, Books, Phone etc.; this bag had so many hidden compartments that you could put many items inside comfortably. I kept the charger accessory inside but removed the hard drive because he did not quite know how to master that (I'll show him how to when he comes home on breaks). I"m the grandma tech-geek in the house and once I get the gist of something, then I can teach the kids how to get the most out of the product. He does use it to charge up his phone and laptop when he forgets to plug them up in his room at night. I was going to purchase another one for my granddaughter and myself, but the price went up twice as much. I guess I have to wait for some special kind of sale.
