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. ## Frequently Bought Together - Voltaic Systems OffGrid Solar Backpack Charger with V50 Battery Power Bank, 10 Watt | Powers Phones, Tablets, USB Devices, & More - Voltaic Systems V50 Always On External Battery Pack with Dual USB Ports - 12,800mAh - POBADY 2PCS U.FL IPEX to N Type Female Low Loss Coaxial Cable 6" /15CM U.fl/IPEX RG178 Coaxial Pigtail Cable for Wireless Routers Mini PCIE Network Cards PCI Wi-Fi WAN Repeater --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tw/products/51488133-voltaic-systems-offgrid-solar-backpack-charger-with-v50-battery-power](https://www.desertcart.tw/products/51488133-voltaic-systems-offgrid-solar-backpack-charger-with-v50-battery-power) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-09-01*
