30W Portable Solar Panel Charger, Foldable ETFE Monocystalline Panel with USB-C USB-A and DC Outputs, IP65 Waterproof, High Conversion for Phones,Power Stations, RV, Outdoor Use

Absolutely phenomenal, very happy with the performance of this panel!The panels have a stiff outer layer and they stand upright well with the attached kickstands, and the entire panel folds up small enough to fit into a laptop sleeve, which is how I carried it to the top of a mountain to sit and read my kindle, do recommend!I have a USB-C power meter that I can use to see the instant power output and I got ~30 watts in bright full sunlight and ~9-15 watts when cloudy. The Kindle used only 5 watts to charge so I left with a full kindle battery and full battery bank after about an hour of reading!Lightweight, compact, portable, fits in a backpack, provides more power than ANY of the wall plug chargers I tested (15 - 24 watts) and I could definitely run my Raspberry Pi off it (9 watts) even when cloudy with a battery.Plenty of power for charging on the go, like having a USB-C fast charger from the sun!

Very efficient solar panel to harvest energy from the sun! I have a power bank that when fully charged provides about 15 hours of electricity. This is great when I’m camping, fishing on the boat. This solar panel has enough surface area and wattage to help charge my power bank back up. Im sure this could be used for a variety of uses. It is portable, durable, and efficient!

Had it for two months, since March. pulled it out from inside and attached it to my backpack. Halfway into my bike trip, I noticed it failing to charge one of my portable chargers. Stop to play with it for a bit and noticed a connection issue.The solar panel comes in a series of panels. They are all connected and when one fails, they all shut down. In this case, multi meter tool spotted one of them not working thus the entire thing not working.Due to the design, I can't just pop it opened, and fix the issue.Make sure you get a warranty.Otherwise it works as entails. On a bright day, I can fully charge two devices between 11 am to 2 pm. 180k portable chargers.For the cheap price, it is worth it. Decent quality and durable. I dropped my bag on it quite a bit when tired of biking up hill.Easy to use with holes in four corners. Just slipped nylon rope hooks in and attach it to whatever.Not too big when it is folded.

Ordered these for upcoming summer camping trips and they have been very reliable. I was able to charge literally anything: laptops, phone, power banks etc etc. These also comes in a case which have a zipper to close, so it is more of a thin briefcase by the looks making it extremely convenient to carry around anywhere.

Just stopped working for no good reason I can see. It wasn't dropped bent twisted sat on thrown or left in wet conditions. It just stopped working. When I open it , it seems to work the red indicator light comes on after just a few minutes it goes off and stops working for the day. Any customer support for warranty service would be appreciated thanks in advance.The seller actually had a prompt and positive response to this review and quickly, as well as professionally resolved this issue for me. Thanks a lot. You definitely stand behind your product. Will buy from you guys again for sure. Five star seller standing behind a five star product. For sure.

It works for small items

Nice 60 watt 4 folding panel set up. Says monocrystaline (all wafer cells in one direction) much better than multi-crystalline (cells face all over/different directions), for better solar collection. Seems sturdy build over all feel and appearance. Has 2 semi soft legs to stand up.Accessories:Nice soft case with internal security straps. The adapter tips and cords came loose, so, were then put in a zip lock bag, until I find one of my small cloth tool pouches. Bought a usb male to male cable, to plug into my port charger/lighter port, for trickle charging vehicles battery for those new vehicles that have a higher sitting around drain.3 days after showed I put on hood of truck and measured output. Never really know if you bought a good set, or a lemon set, until you test.Results: 21-22 volts on voltmeter, 2.1-2.4 amps, (amps x volts = watts) 50+ watts for an off angled direction reading. I’ll take that any day.

Off gassing heavy heavy heavy smell- EXTREMELY STRONG SMELL. Very unsafe for a small space-- would not want to travel with this in a small space. wow. I messaged the seller to tell them and ask about manufacturing and they were impossible to communicate with. Could not answer the question and just bypassed my inquiry with "we hope you enjoy this product, all natural, nothing toxic". A very dishonest, unprofessional response. I would prefer , yes we use glue in manufacturing that you might be smelling, please leave the product in a ventilated area for x amount of days, or some sort of honest exchange.The cord is short and no information on the output size so I’m having trouble replacing the cord.
