Dependable
I've been using this one that I bought maybe 5 years ago, and it has been very dependable and is a great value. I typically charge small battery powered camping lights, but sometimes charge my Jackery battery, it works great either way.

Provides peace of electrical means on trips
Folds up easy with Velcro straps to firmly close up and has a handle. Does take a good 7 hours time to charge my charger in the sun but once it does the charger holds a charge for 7 hours. Will continuously charge on the dashboard of car thru window which is convenient if you don’t want to use the cord it comes with to charge via car battery while traveling. Not recommended to charge via car if not operating the car it will drain the car battery but I have a 120 outlet in my car so I can use that too if necessary. Not bulky and easily stored away in the car.

Good Quality, outdated charging ports
It does its job - it charges devices. It comes with loads of power adaptors that I have yet to need. Most electronics I use are past the USB-A generation and typically all use the USB-C. Unfortunately, this product only has a USB-A outlet which makes it slightly less desirable for directly charging things like a phone or portable charger. If it was to get another, I would definitely want USB-C compatibility and this is something I should have looked into before purchasing.

Solor panel
This product is very nice and I am okay with the product it's just that the fact that it is a little pricey but that makes up for itself by producing the correct amount of power but the downside is that u have to have the sun to use it but when the weather is crappy don't expect it to work tried it and it did not work after that I just put it up in my closet because it is useless unless u have real sun rays for it to work and so I give this product a 3 out of 10 and then I probably give it away I have no use for product that doesn't seem to work how it's described in the description and it was a waste of money and time purchasing it and I give this product a 3 out of 10 because of the issues and u guys need to fix ur add and tell the truth because u will get way more products sold if u just tell the truth

High Quality, Powerful, Compact & Convenient!
This solar panel was used in a recent trip. This solar panel works very well in full sunlight. When it is partly dark or cloudy, its charging speed is slower which I found to be acceptable for charging my phone, external speaker, portable speaker and headlamp. I love how compact, easy to use and that it comes w/ so many adapters to outfit all ur charging needs! I highly recommend this solar panel to anyone who wants to charge compact electrics.

Great for a variety of usb devices. Works great in overcast weather as well.
Plan was to charge a portable power pac for outdoors and emergencies. Was surprised to find that the solar panel itself has a variety of different sizes of outputs that can charge about any usb devices!! Love it. Great in emergencies too.

Works good and size is perfect
Looks durable and decently built, time will tell. Charging a power bank now over usb c, seems to work. Weight is great, fits in my backpack for daily use. Will see how long it takes to charge my laptop from 50% to 80% see if it has enough oomph to charge it quickly or even if it will charge it. Easy to use and has nice kickstands. Too bad it came used and dirty already. EDIT UPDATE: Seller was quick to respond with solution.

The backing on the solar panels is a bit thicker than other solar panels but it will prevent cracking and damage which is great. It actually outputs over 30W which is incredible because most other sellers would list this as 60W in that case for portable foldable solar panels. The output is the biggest downfall of this solar panel. It only has one usb output and its 5v max which mean you’re getting a total of 10w out of the possible 30w. Huge waste . I got this becuase I have a Drok dual usb output buck boost converter which essentially adds more USB outputs to the solar panel but at a cost. I already had the converter so I’m not sure how it would add to your total cost of the system ~$20usd But would allow you to have 2 12v or 5v USB outputs that you could use at 12v 1.5A on two portable batteries or you could use the DC wire to plug into a Jackery battery, which is the method that I would recommend if it is applicable to you.
