ENGINSTAR 60W Foldable Solar Panel Charger with 18V DC Outlet for Portable Power Stations EnginStar/Jackery/Rockpals/Flashfish, Portable Solar Generator with QC 3.0 for Outdoor Camping Van RV Trip

Excellent and affordable product. I was able to test these out and get a decent charge for my portable battery even in lower light conditions. Easy to use, and definitely valuable for the cost.

I was pleasantly surprised at the ease of use of this unit. The solar panel unfolds for use effortlessly and charged the unit fully in about two hours. I have run a small fan and a utility light briefly. I have been charging my watch and anything else needing a boost with this to see how rapidly it discharges. It hasn't come off of full charge yet. I am in Florida, so charging is easy and I will find this priceless during hurricane season.

Have had this product for over a year and it has worked great for me. Would recommend. When my old 60W finally bites the dust, will most likely buy another one of these

Pretty good wattage and voltage for the size. I mainly purchased this for the DC voltage output, which was showing between 19 and 20v DC in the spring afternoon sun.

Purchased this to recharge my battery pack for camping. I have to bring my CPAP machine while camping or the whole Northern Woods will be awake for the nights! This 100 watt panel does deliver as described. Worth noting that the best output is in full sun. That being said... even with passing clouds, this panel recharged my RockPals battery pack in a matter of a couple of hours, from 20% to 100% daily on our 5 day tent camping trip. This panel does fold to a rather flat briefcase style pack weighing around 5 pounds-ish, which packed nicely in the gear totes. This panel can be floppy when trying to arrange an array, though a little patience and utilizing the terrain, I was able to achieve nearly 70 watt output in full sun.

These solar panels charge quickly. Easy to move to different locations. Sturdy. Compact. Convenient. In the aftermath of Hurricane Helene they arrived right on time with no shipping problems and saved the day!I was without power for 11 days. Gasoline was not available in my town as 98% of my county was without electricity. The gas pumps don't work without electricity, but these solar panels do!

Utilize it on its own or to power up other units!

I have only gotten to use this product a couple of times so far. Took it on a camping trip and used to keep our battery stations all charged up. It did well. I didn't get a chance to really check charge rate because our battery packs never really got below 80%. But this solar panel certainly did what we expected it to do.It is fairly easy to set up, although the "legs" can be a little bit of a pain. But I leaned it up against one of the bigger coolers for additional support. It folds up nicely and is small enough to fit in most storage locations.Overall, I'm happy with it so far.
