MARBERO 100W Portable Solar Panel 100 Watt Foldable Solar Panel Charger for Power Station, USB/DC Devices 18V Output(10 Connectors) >23% High Efficiency IP68 Waterproof for Camping Outdoor RV Cloudy

Got these to go with a battery charger I was bringing camping. Very happy that it worked with my charger! It looks really nice and folds away well. It's been overcast so I can't honestly say how well it chargers in full sunlight, but it was working with overcast. It's installation is super easy and quick setup. I feel the charging speed is good for the watts and it's good value. It feels like it's got good quality I'd love to get a 100 watt solar panel from this company.

Product is very good and as described. It is a good value for the money. It is convenient for carrying and includes several outputs. There is some difference between the product description and the specification sheet came with the product regarding the Type-C power rating (60W vs. 20W respectively).

Nice combination of physical size, performance and package with accessories and storage pocket. Glad I went with 100W because partial shade reduced output. Charged up a 300W lithium battery power pack in 7-8 hours to run a Cpap machine at night for my wife. Had to reposition a few times to get most direct sunlight possible. Got the job done. Had also bought a second solar unit to do faster charging but instruction book did not explain how to do that so used that 2nd one for phone charging, was an easy task for multiple device charging. Happy WI camper!P.S. Had to run the Cpap machine in an energy saving mode to get the most run time from the 300W power pack.

Work great. Charging about 46 watts on average and that’s ideal for this size of panel. Not disappointed one bit. Matter of fact in satisfied. Highly recommended for the price point. Using it on a goal zero yetti as well.

I tested this today. My phone has a 4200 mah battery, and in full mid day sun under ideal conditions this panel charged it from 0% to 100% in 1 hour 40 minutes. While there is no kickstand, carry bag, or any other frills what so ever, this panel packs a punch where it counts and is well worth the money.

This was procured to provide back up charging capabilities for our phones and portable dental equipment batteries while on a mission trip to Zambia. It turned out to be necessary due to the unpredictable and interrupted power grid. It was easy to set up and the wide assortment of adapters meant everything we needed for charging was included.The panels fold to a very usable size and everything fits snugly and safely in its protective carry case. This fit nicely in the bottom of a Costco tote (which is what we used for luggage). It should likewise fit into a large suitcase.

Great functionality

Amazing! The 30w charged my large battery pack in less than 10 minutes on a decently sunny day. Generally it takes 2hrs plugged into the wall. Better than the panels on my roof.
