Fair but slow for power station
Good for phones charging and small devices. Too slow for powerbank/power station charging. So that’s why a 4 star.

Trail test
I took this solar charger with me on a 6 mile trail walk to do a test on this product ….. it failed the test …. But was not completely useless ….. it was charging when it was in full sunlight but when it was shady it would quick charging ….. when the sun was strong again …. I expected the item I was charging at the time would start charging again …. Unfortunately , it did not …. Unless I unplugged the device and plugged it in again . I tried it on a solar battery generator that excepts solar charging and also my iPhone . In both instances ….. it responded the same . I found it annoying that I had to reconnect it in every time a cloud came over and stopped charging . I would not purchase one again . I had a large group with me and recorded the demonstrations on a live feed to about 16,000 members …. Trying to explain the use of solar power . Not a recommended product . 5 other products were also demonstrated and did well . This was the only one that failed . Later , I did some modifications to it and was used to run a solar fan in a shed . But was permanently taken out of Field service . It looked well made …. and it fit perfectly into my personal travel backpack . I was really disappointed when it did not perform well . It would have been my new main traveler .

Great Purchase!
Extremely satisfied with my purchase. I hiked over 30 miles through the Sawtooth Mountains with this thing strapped to the back of my back using the supplied carabiners. Not a single issue. I thought it might be a single use purchase for the price point but its back home and ready to go on my next adventure too. Extremely lightweight and it did great charging phones, banks, SOS devices, and vapes for the entire team.

Defective
One of them came without the part to plug into my solar battery pack. I don’t know what to do with it.
