SunJack 15 Watt Foldable Weatherproof ETFE Monocrystalline Solar Panel Charger with USB for Cell Phones, Tablets and Portable for Backpacking, Camping, Hiking and More

Six weeks in Africa with no electricity. Camera, personal fans, headlamps, flashlights, and the rest of the team without a source of electricity either. So we jumped on the SunJack with an Anker Astro E7 26,800 mAh, Cannon USB battery charger, and a SunJack USB battery charger. I wasn’t sure about the ability to charge all the devices, but I figured it couldn’t be worse than having nothing at all.Before leaving for Africa, we spent two weeks “prepping” in Florida, and the SunJack charger immediately proved its ability. Even though there was no direct sunlight, the solar charger kept the Anker fully charged and all the batteries for the team full and ready for the evening. While in Africa, the setup was worth its weight in gold. For the dollar, I couldn’t imagine a better solar panel. While it did add a bit of weight to my overall pack, it was worth having that fan on me at night, the ability to capture memories with my camera, and illumination at night while avoiding snakes. The ability to charge all the “AA” and “AAA” batteries, cameras, and other miscellaneous electrical devices is a life saver.*Update*Almost a year later, and I am still in love with this solar charger. I have taken a few more international trips and have taken this with me. It has proven itself to be a great security blanket in our electronically controlled lives. This charger is a year older, a bit dirty, but still works harder than some of the folks I travel with!

My boyfriend and I just used this for a 6 day backpacking trip in Sequoia and Kings Canyon. We used it to charge our Anker 10000mAh battery pack which was then used to charge our Garmin inReach and iPhones. This solar panel is the real deal! It worked effortlessly and charged extremely fast. I love how it’s 15w and weighs basically the same as it’s popular 10w competitor. We used it both propped up at camp, and strapped to the back of our packs and both ways worked great. Very pleased!!

Used this on a 4 day hike, kept my Iphone charged to 100% with my mapping app active the whole time. I use it at my cabin while streaming music. Sunny, cloudy....didn't matter.It didn't work the greatest on my dashboard trying to keep a tablet charged up during a road trip....it was a long shot....and really cloudy. I would reccomend this to the outdoor adventurer. You really want to make sure all 4 corners are strapped down so it doesn't hit you in the rear-end....

This has the power to charge my cell and or my power bank just as fast as a wall charger, I wouldn't bet anything less than a 20 watt, it cost a bit more but i think its worth it, very satisfied and would recommend. comes with 2 charging cords and has a place to hold your phone while charging. very nice.

I just receive it 3 days ago.so my review is limited.Old analog qwerty cellphone-it charges as long as there is light eventhough it rained 3 days consecutively.i loved it.Smartphone-i don't owned one so no idea if it's charging.Tablet-it needs direct sunlight to charge.if it's cloudy,it keeps blinking.Power bank 10kah-charges eventhough it's rainy as long as there is light.Price-a little bit expensive.All in all i loved it.since my area experience black out almost everyday,i hope it can charge my little gadets eventhough it's rainy season now.if there is a problem,i will update my review.

Got my powerbank charged to full in about 6 hours in the Cali sun. Functionally, pretty perfect. However I'm looking to do some ultralight backpacking and it feels about 8 ounces heavier than I would like. I may keep looking for something lighter that is equally useful.

This the best solar charger period! As soon as you open the box the red led on the usb terminal came on telling you it is charging! I tested it out side at 7 pm the sun had just set and this 14 watt was charging! I also own the 5 watt with the battery pack built in. I held that one near a fluoresce light in my basement it it started charging. Sunny! Cloudy! it dose not mater Sun Jack will jack you some uv rays charge the days! Sop looking Buy It Now!

This is a most handy piece of equipment. We set it in our windshield while driving or clip it on my backpack if we are overnight hiking and we always have extra power. It charges quickly in the windshield. Charge times while hiking are longer due to the angle at which the panel hangs, however if we are hiking all day it will still get the job done. If not we simply lay out the charger in the sun once we have stopped. You can buy the entire set up with two battery packs or just the charger and the battery pack separately. When we bought it was actually cheaper tpo buyu the components separately so check before you buy.This was my second purchase of this item. The first worked perfectly but got left in a rental truck and "disappeared". I had no hesitancy buying this a second time.Highly recommended.

I live in Singapore. This solar charger performs well from 8am to 6pm. The photo shows a reading I’d typically get when it’s sunny, 4.95V and 1.97A. When it’s cloudy, I’d get about 0.5A.This 25W solar charger has 2 USB A outputs. When 2 USB devices are connected to both ports, the highest total current I could get was 2.7A (~13W).It’d be best to use a good usb charging cable. Also, the shorter the cable, the higher the current.The built quality is great and it feels tough. There’s a magnet that keeps the panels folded together for easy packing.The solar panel became faulty after a few months' daily use. 1 of 3 panels stopped working, reducing the total output. I've returned the panel.

So VERY, VERY disappointed in this product. It simply does NOT do what is claimed. I placed it in full Australian sun - Queensland for 4 days & it still couldn't charge a 60 % mobile phone to full in less than 4 hours. The product information clearly stated it could do this in 2 hours.I want my money back

Very happy with the price and product 👍🏻
