SunJack15 Watt Foldable IP67 Waterproof ETFE Monocrystalline Solar Panel Charger with USB-C and USB-A for Cell Phones, Tablets and Portable for Backpacking, Camping, Hiking and More

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 👍🏻

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....

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!
