SunJack 15 Watt Foldable IP67 Waterproof ETFE Monocrystalline Solar Panel + 10000mAh Power Bank with USB-A and USB-C for Cell Phones Tablet and Portable for Backpacking, Camping, Hiking and More

Works well, charges pretty quickly and lasts long enough to do a couple phones, a gps, headlamp or Garmin Inreach. I have not tried to drain it on charging electronics in mass. Two or three items and then you need to recharge the power bank. Great for backpacking… lightweight and slim!

I just finished RAGBRAI and did it self-supported. Each day I rode with the solar panel “out” and attached to my panniers by caribiners, with an extra bungee cord for stabilization. The panel would charge the battery pack. Then, at night I used the battery pack to charge my Garmin, hand-held fan, and iPhone. It worked flawlessly. This system works very well. Recommend!

I bought this for preparedness and I am glad I did. We lost power 3 times in an month for various reasons and I was sick of worrying about if our phones are dying. The name backpackers series is fitting. Be sure to read the description. It explains that it charges best in direct sunlight. Through a window is NOT the best way to charge it. I found that it adequately charged if I put it outside on a sunny day, so I can see why the name is backpacker series. Which is fine, because it's weather resistant anyway. I tried to charge it in a window with sun directly hitting it, and it didn't charge well. But, it charged well outside in the sun.Make sure you understand the device itself doesn't hold a charge. I bought the one with the external power bank. If you don't, you either have to charge your phone or devices directly by the device. I didn't try this. I prefer the external power bank. The power bank from sunjack charged my phone about as quickly as plugging it into the wall charger, so I'm very pleased. I will be able to use it to charge all of my external power banks and my rechargable lantern. It's peace of mind the next time we lose power.

easy to use and convienient to pack for a camping trip.

Works great and charges fast, I am going to use for a bicycle trip where electric connections are going to be limited.. Attach the panel to my bicycle and ride while battery charges..

the included USB-C cable does not work. Tried same cable on a normal wall charger as well -> NOGO. I used a USB-C cable that i had on hand and now seems to work fine. Most lily will return and replacement.

You’re not going to go off grid with this but it works well

I love it! It comes in so handy on my kayak/hiking adventures. It's pretty quick to charge a phone, even in the shade. I'll be getting one for family in natural disaster prone areas.
