There is no cell service where I was so the phones were kept on Airplane mode most of the time. But with people taking pictures/video, and watching some movies, a new iPhone and Samsung were kept at full charge for the trip. I pre-charged the battery before leaving. While you can charge a phone directly off the SunJack, you're best off charging a dedicated battery through the day, and then re-charging devices in the evening off the battery. The solar panels are quite rugged which attributes to some of the weight of the unit. I essentially left it outside for our 7 day trip, never taking it inside the tent. So it went through sun, rain, cool nights, and morning fog (so much dampness in the air, all our phones were reporting moisture in the USB ports), It was also left perched up on a rock in the sand. No issues whatsoever. It is somewhat larger than I expected, but I wanted to be sure I had enough wattage to keep everyone topped off. The small battery packs with a solar panel built-in would take days to re-charge the attached battery, so that was not going to be acceptable. I was also able to charge my drone battery and controller. I especially like the attached nylon zipper pouch to keep cables and the battery with the panel. It came with some USB cables, but we had a few different devices with us so I needed a bunch of charging cables. The pouch really helped keep the "charging station" organized. Almost zero weight added to the overall system, and really worth it. Setup is super simple, just attach a dedicated battery or phone (whatever you wish to charge) and your off and running. I didn't have a volt meter to measure actual output, and most days were sunny, but even in the early morning, I'd attach the battery and see the light blinking on the battery so it was charging if even a little. I could probably have kept 4-5 phones topped off, but for our system, I'd just set it and forget it. Then remove the dedicated battery in the evening to recharge a phone overnight. Then, just re-attach the battery in the morning. The battery would be fully charged by mid-afternoon (on a full-sun day) so people would top off periodically. Essentially it worked as expected, is light enough to backpack, very durable, and worked like a charm. So if you can spare a little room in your backpack (I never traveled with it hanging out of the backpack) you'll be quite happy with your investment.

Finally. I have had them all. *by J***N on May 12, 2025* Works. Finally. I have had them all. I literally have 10 different solar chargers. At best 1 out of 4 solar chargers actually work. Most are simply scams or overrating their output so much its silly. I need them for work (expeditions - reality shows). This one works. It does not output 15w, but it does output about 5-6w and does not discharge your battery backwards in cloudy weather or shade. Yes. Backflow into the solar panels is a real thing. ## Frequently Bought Together - SunJack 15W Solar Charger Portable Solar Panel with USB for Cell Phones, Tablets for Backpacking, Camping, Hiking and More - SAWYER Outdoor Water Purification Filter Spare Parts Bucket Bucket Conversion Inline Quick Fill Adapter Screw Coupling Kit Sawyer Accessories (SP115 Fast Fill Adapters for Hydration Packs) - Cnoc Outdoors 28mm Vecto Water Container --- ## 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.es/products/18907834-sunjack-15-watt-foldable-solar-panel](https://www.desertcart.es/products/18907834-sunjack-15-watt-foldable-solar-panel) --- *Product available on Desertcart Spain* *Store origin: ES* *Last updated: 2026-05-25*
