Solar Charger Power Bank 36800mah with 18W PD 5V*3.1A Fast Charging, QC3.0 Portable Charger Solar Power Bank,IP67 Waterproof Camping Gear Accessory for Outdoor (Blue)

This is essential if you live in an area that loses power regularly or are attending an event where you don't have power for your device. It can be charged up via the sun or via an AC adapter for your wall outlet. I always have mine with me when I take frequent bus journeys.

Back story, I have purchased 2 of a cheaper brand. Well, come to find out that they didn't work as described. I even bought 3 more for family Xmas gifts. I gave lousy presents this year. What a waste! NOW, I bought these as replacements. Yes, a little more $$$but, worth it, honest. They take about a day to fully realize charge. In Bright sunshine. You then can use these as portable power bank. OR, hook up your phone (it charges 2 items at a time) and the sun charges them without depleted power of the bank. These also can be charged with a USB. Which I use for initial use. Charges faster than solar. Then you keep them charged for whatever...mine sit on my bedroom windowsill. I REALLY LOVE THESE. Good to prep and store for the price. Awaiting for power outages and man made chaos. I truly recommend these. TEL

Solar charger works well and charges quickly (in bright sun). The picture is a little deceiving as it looks like the case has silicone grips on the side. But it is actually just a different color of plastic, so I does slip a little if used on the dashboard of a car or just holding in your hand. But now I don't have to worry about running out of power when out on the road.

It worked fine til it quit. Looked good, worked well til it didn't. Quit charging and won't take a charge. Ran out of power shortly after return allowed. How convenient. Very disappointed.

We purchased one of these about a year ago and it works so well we decided to get another. I hunted until I found the exact one and bought another. These are great to take on a trip, camping or just outside. It charges phone quickly and the solar feature is great! Highly recommend!!!

wont charge anything with the solar pannel

This 2-star rating is based solely on the fact it has a micro USB port rather than a USB-C. Had it a USB-C, I would've give it a 5-star rating. The product does everything I want it to do. However, the micro USB severely limits how and when I can use this external power bank.

On a full charge, it lasts very long. I have not used its solar ability yet but this is a very good alternative for power source. In my case, I had some rodents building nests in my van. I bought an ultrasonic under the hood device and then connected to this. BAM! I it is now a self contain system since I did not want to connect the ultrasonic under the hood device to my car battery. The QC is an added bonus. The other usage that I plan for this is for traveling when I am on the plane since TSA will not allow me to have my car jumper battery pack. I ended up buying 4 and gave some to my sisters too.
