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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ The perfect off-grid or commuter backpack *by Z***Y on Reviewed in the United Kingdom on 26 October 2020* I love this backpack! All my devices fit in (including a large laptop), pockets make for easy and neat packing.
