Summary: A very heavy duty backpack / book bag targeted to students, with much left to be desired in integration of the battery pack - the sum of parts is less than the whole.
I went on a week long vacation in Jamaica recently and after returning was going to be a lot more critical of this backpack / battery combo, but then after some thinking, concluded that I'm probably not the target customer. The person who would benefit most from this combination is using the backpack to lug their books and stuff to class or work on a daily basis.
The hook is that they've built in a 3000 mAH battery with cables to charge any portable devices to give you some extra life for phone calls when riding home on the train or sitting in a Starbucks flipping through your iPad. If you're getting on a long flight, this isn't going to do much at all for you. The external charge port means you plug in your backpack, rather than having to plug in a device and remember to put it in your backpack.
So what's my beef?
1) Far more of a cool looking consumer backpack than something functional. Adjustable sternum strap is nice, but they prioritized this over a hip strap? Mesh shoulder straps nice but the back part does NOT have mesh - which means it really isn't going to be very comfortable for carrying for long at all. As a student daypack for books, that's fine, but I'd also want to be able to take it on a short hike now and then. Lots of padding and stiching which does nothing but make the bag heavier and bulkier.
2) Padded laptop compartment...isn't padded on the sides. They designed a really cool pocket for a laptop but the padding is ONLY on the large flat sides of the laptop, not on the sides and bottom where you really need it. FAIL.
3) Proprietary battery - replacement / upgrade battery inserts cost several times more than compete external battery packs from other makers. Did Sony make this backpack?
4) There's a really nice slot for a tablet, but forget about charging it with the supplied cords - they're too short and tied to the charging slot on the side - you'll have to bring your own cord.
5) 3000 mAH is good for phones, MP3 players and the like, useless for tablets. (Also see complaint #4.)
7) Charging lights barely very visible. In the video you can very clearly see the blue status lights, however on mine, the white status lights shining through the heavy black nylon are *just* visible in side, and basically invisible outdoors.
To recap - the backpack itself has some cool features but overall lacks the capability of offerings from companies like Case Logic, Jansport, Deuter,, etc. The battery pack performance is lacking and integration has limitations. I'd recommend getting a good backpack and separate battery pack.
Here are a few battery packs - if you're just charging a phone, 2000-3000 mAH is fine, for a tablet, 5000-7000 is better.
