GRECELL 100W Solar Panel for Power Station Generator, 21.5V Portable Foldable Solar Panel with Fast Charger and Adjustable Kickstand Solar Cell Charger for Outdoor Camping RV Van Travel

Works so well in the sun! Charges fast - I have a 300w battery and it takes about 4 hours to charge full which I think is pretty good! I’m really glad I went with this one ☀️

I absolutely love my Grecell 300T power pack so I decided to buy the solar panel to be even more mobile. I couldn't be happier. Haven't used it a lot yet, but have set it up and charged power pack a few times and so far it recharges faster than I felt it would in winter with partly cloudy skies. Is light weight, easy set up, handle makes east to move around. Appears to be very well built and sturdy. I have recharged power pack (at 88%) while charging my tablet (at 65%). Both charged 100% in a about an hour. I am thrilled. Price is well worth it.

They work great!

I have using Grecell panels for several years now. I bought this particular style because one of my original panels was damaged. This particular design is the best by far in my opinion. The adjustability of the legs is wonderful , and the solid leg rather than the cloth covered style is so much better for the gravel that I am on. I have confidence that it will last much better than the original design. Although it is more expensive than the other style, I feel it is definitely worth it. I am quite happy with the purchase.

Lightweight, handy pocket for your hookups and lightning fast delivery!

This solar panel has a unique design I've not seen in a portable solar panel before. Most panels I've used have the panels attached to the folding case and the angle supports fold against the back of the case. With this panel's design, the opened case sits flat on the ground and the angle supports sit on it, leaning up to support the panels. This design apparently allows the solar panels to pass some light through them which reflects off the reflective surface of the inside of the case and generates a bit more energy coming back through the panel. I love the innovative thinking and maximization of the output of each panel. However, in practice I don't love it.The first issue is that you have to lay the outside of the folded panel right on the ground. If you want to set up the panel in the morning while there's still dew on the ground that means getting your panel wet. If there's red dirt like there is near me, the outside of the panel turns red quickly. This is the side that should be kept clean so that it can be stored in a camper or vehicle without getting everything it touches dirty.Another downside to this panel is setting it up. You have to remove 3 separate support legs from pouches in the case and then attach them to the top and bottom of the panel. That's 10 different things you have to do before you're ready to stand the panel up. Compare that to the standard folding panel design where you just open the panel, flip out the back supports, and you're done. This panel takes 3x-4x more time to deploy and pack up.The power output box where the cable comes out and where there are USB ports is on the front of the panel...right in the full sunlight. Every other panel I've used has had this box on the back of the panel out of the sun. The components in this box will be exposed to direct sun while using the panel and could fail over time from getting too hot in a small unventilated black box.When setting up the panel on the reflective outer case, the way the case drapes over grass, stones, etc makes it lie uneven on the ground. The panel that stands on top of this uneven reflective case then also tends to want to bend and not face directly towards the sun. This can even be seen in the manufacturer's video. Sure the panels roughly face the sun, but it makes me wonder if any extra efficiency gained by the unique reflective ground layer isn't more than offset by some of the panels pointing 5° or 10° away from the sun.While I appreciate the originality and ingenuity of this solar panel in some ways, for me the downsides outweigh the plusses of this unique design.

These solar panels worked great with my Grecell portable power station. Charged it up with good wattage input. They are flexible but sturdy, easy to collapse and carry away like a briefcase. Perfect for off grid use which is what I needed.

I purchased those item out of fear when these horrible storms hit the south.This panel is easy to use and it was a great value for the money spent.It provides us with a nice power source and it’s very versatile and the cables are not all over the place when in use.Great for that unknown.
