I tested the PWR Solar Panel 10W on an 800km coast-to-coast traverse of the Pyrenees (days were mostly sunny). Thanks to Knog's solar panel, I was able to keep my devices (phone, bike GPS, watch, GoPro) continuously powered. A really superb tool for self-supported outdoor adventures.
super leuk om te hebben met het kamperen.
I'm pretty happy with the product, even I haven't tested yet as its max. I've tested at home and, for example, fully exposed, it chaged my old Iphone SE (1st gen) from completely drain to 40%+ in something more than an hour. So, It can really help charging a way vriety of devices out there in the wild and helps a lot.
PWR Solar Panel 10W
This solar panel is the best I could find for backpacking after considering the various criteria that go into my gear choices: weight, durability, functionality, and compactness. The materials and build are very solid, it charges efficiently, and it's very compact. The weight is a bit higher than I would like for long-distance hikes, but then again this product was probably optimized for biking. The rubber material is likely the issue, though going with a lighter material could compromise the durability. I would also like to see the USB-A port replaced with USB-C as most of my gadgets use that standard now. I bring along a Lever Gear cable kit, which includes any adapters I need, as a nice lightweight complement to the PWR Solar Panel. My primary mode of use is to charge an Anker Powercore 5000, which I then use to charge my other electronics. To summarize, I think the PWR is a best-in-class product for a portable and robust solar charger, and I would highly recommend it to any hiker, cyclist, or anyone else recreating in the outdoors.
