## Description

Portable Solar Panel

Review: Nice and working fine - Product sahi hai, OnePlus 7 pro 50% charge hone me 2hrs liya. Light weight v hai. Product ka finishing v sahi hai. 2 usb slot hai, two device at a time charge ho skta hai. But proper sunlight need hoga, forest area and rainy season me iske bharose kaam nhi chalega. agar 2 hrs v proper sunlight me use kro to kaam ho jayega. Maine 2K me liya tha.
Review: Very finicky and unreliable. - I’ll definitely be returning this. While it works, in the sense that it does provide power.. it is not very reliable at all. You can’t leave it unfolded all the time with a battery plugged up. Even when it’s bright outside, if it’s been left unfolded it won’t charge until you fold it and unfold it again. I wanted something I could hang in my window or leave on the dash of my car and have it charge whenever it was bright. The charging speed is also not very good, the dc port often won’t have any output when it’s not very bright out. And getting it to work when it’s not completely sunny is not always reliable. I don’t think it’s very well designed. It also doesn’t charge very fast even when it IS very bright out. I did a trial with a different portable solar system with the same max output and the other one (flex solar) was much faster and actually gave the max output it listed. It’s also important to note that even with an DC to USBC adapter, my laptop would not recognize it as a power source. I was running tests on the panels output on my laptop and it didn’t even say it was charging even when it was completely sunny out. So really, the more reliable port is the usb port, which is a 5 volt max. For the price, there are other systems with multiple outputs available with higher charging speeds. This one is not one of those. I think the only reason to choose this system is if you are going to be using it rarely, and you are okay with having to do a lot of manual work for it to actually charge stuff. And if you aren’t wanting a quick charge.
