Review: Worth the price - This backpack was worth the 200.00. I love the extra compartment for tablet/laptop and the main compartment has so much room. I didn’t write a review immediately because i wanted to see how it worked for being a general commuting/work backpack. To say the least its very comfortable and the solar charged battery is a lifesaver. I use my iPad Pro 12.9 for work and i am always on the go. I haven’t used the whole battery but it has been more than enough to give my iPad enough juice to get things done and have enough charge left over to charge my AirPods and iPhone 7 Plus. I highly recommend this backpack. Update (26 August 2018) Still amazing. This pack gives me a lot of convenience and is very sturdy. Would recommend to anyone. So far I have used to to hold my work stuff, hike and bike in San Diego.
Review: Looked great. Quality product. - I bought this for travel. It's very secure. I would like a better configuration of the pockets, but it's a good bag.

## Questions & Answers

**Q: is the battery back the new V50? From pictures it looks like the old one.**
A: The current version on Amazon has the V44 battery pack. The V50 is currently only available directly on our website as of today (September 16, 2019).

**Q: My battery pack is now 100% charged.  If I don't use it, how long will the battery last (days/months)?  Thank you!**
A: We recommend making sure you use or recharge your battery every 6 months to maintain the battery's performance, but if full the battery should hold its charge for about 1 year.

**Q: can this charge other battery packs as well?**
A: Yes, although most battery packs are designed to charge well from solar. Some have low current cutoffs, others can only take a narrow range of voltages, etc.  If you want to charge other battery packs, we suggest adding a regulator to the solar panel output - https://www.voltaicsystems.com/solar-usb-regulator

**Q: Is there room 4 a camelpack?**
A: Yes - we would place it in the laptop / tablet compartment in the back of the bag and then run it down the shoulder strap. You would want to improvise some sort of clip or strap to hold the Camelback to the shoulder strap, but that should be relatively easy.
