The Powerbag Backpack is an awesome portable charging station. Obviously it’s not just any ordinary backpack, this one has a long-lasting battery that will charge up all your devices on-the-go.
The Pros are almost endless.The Powerbag has a 3000 mAh Lithium Polymer battery and also includes three cables for charging; a 30-pin for all your iDevice needs, a Micro-USB connector, a Mini-USB connector, and a USB port next to the battery itself. The bigger of the two pockets can hold a large laptop along with a water bottle or even a DSLR camera. The second pocket can hold so many cables, business cards, computer gear, etc. It’s really an amazing way to be on-the-go with all your electronics.
There definitely are not many. However, when I was using this bag around WWDC, I did notice that there was no spot for a water bottle. This might not be of annoyance to everyone, but if you’re at a convention like I was, you’ll want some type of drink holder.
The Powerbag Backpack is great. Like I said, I used this backpack everyday during WWDC and it satisfied my needs very well. I guess you could say it’s WWDC approved! I definitely recommend this to whoever does a lot of traveling or goes to conventions and needs to charge electronics. This Backpack retails for about $140, which might be a bit steep, but it’s well worth it. Again, here is the link.
