EnginStar60W 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

I used this along with a large portable power bank for when my unit would go to the field. I tested it at home first. The power bank i have shows how much of a charge it is getting and, with direct sunlight, this thing will charge just as fast as the wall outlet. It is easy to set-up and carry around as well. I highly recommend this for campers or those military personnel stuck out in the field.

I am in love with how useful this is! Filled my power bank in less than 5 hours! I am very happy to say I would recommend

This worked great for camping in Yosemite! Got to charge up big batteries and phones just fine!

Good product. High shipping costs. Hard to say it is 30W.Solar charger MUST BE on direct sunlight - not through window or any other translucent material!Where is the reason - is Solar charger defect??

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

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.

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.

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.
