Portable Solar Panel – 60W Foldable Solar Panels with 5V USB and 18V DC for Camping,Cell Phone,Tablet and 5-18V Devices – Compatible with Solar Generators Power Stations

In reading many of the reviews, there isn't a proper analysis of the performance of this solar panel. Most of the feedback is anecdotal.I have set up this solar charging panel to charge a backup battery that I intend to use for portable radio operations (POTA). The battery is a "Howeasy" 88 Wh lithium ion power station with a various outputs including 12 volts DC , 110V AC and USB charging outputs. The battery is charged at 15-24V with a nominal input of 15V/1.5A with a solar panel. The powerpack supports pass through charging.The solar panel is extremely well built and has a heavy duty/rugged quality feel. It folds into a manageable size package for backpacking. The charger is bundled in a heavy duty rip-stop material cover. It comes with a complete kit of plugs that will fit almost every need. The plugs are stored in a pocket designed into the cover.I configured the solar charger with the battery in full December afternoon sun. The charger came to life immediately. It was connected to the battery's charge input. The battery was partially discharged prior to charging. Initially, the charger operated at 22volts at 1.5A (33W) As the charge continued, the amount of current pulled by the battery diminished until the battery was fully charged. For this exercise, I did not attempt to charge a fully discharged battery.With the charger plugged in and opened to the sun, my radio drew 25 watts of power from the battery while the battery voltage stayed right at 12 volts. With the solar charger unplugged, the battery voltage under load eroded to between 10.7V and 11.4V which is a battery issue.Many of the reviews remark that the charger puts out less power than specified. What people need to understand is that the amount of power that the solar charger delivers is dependent on the load (the battery) The battery power draw is determined by the battery's Battery Management System (BMS) that controls the charge rate of the battery. While the charger is specified to provide up to 60 Watts, the battery may not draw this amount as was demonstrated here. A proper evaluation of the solar charger would employ a calibrated laboratory load which I did not have.Bottom line: This is an ideal charger for the power station that I have and I am pleased with my purchase. It is well built and well configured. I would recommend this product.

Works well! My only regret is wishing I had purchased the 100W panel. I use mine with a Westinghouse 160s power station, which allows me to have my own little solar-based power station. Great way to power battery-powered tools throughout the summer without paying for gas or electricity.

I love the quality of this unit, its so efficient, I was able to use it to charge my phone by the light of a full moon. The downside is that the nominal voltage is not compatible with many solar storage batteries so be sure of the capacity of your storage device before you purchase this unit, or you will only have a charger for your phone or computer. Well made, very portable, great for camping, but you run the risk of damaging devices or batteries without paying close attention to the 4 point font in the instructions warning you of this.

Light weight, portable, charges even with cloud cover. Good enough that it charges my portable battery pack fully over 5-6 hours which I then use to charge my phone and watch. You can plug multiple things into it at once. Works really well.

It works I can my 300w power battery in 5-6 hr and it easy to fold, has many different cables. My max was to pull 47w /hr I bought it a few months ago and still happy

I have bought several of these. It appears to produce the rated power for good charging speed. It seems to be well built. It folds to a compact size so that it fits in a backpack. It comes with a large selection of cables and adapters for wide compatibility. It is a good value for the price. I consider solar power such as this to be essential for a go bag because electricity provides 4 essentials: fire (with an electric-arc lighter), water purification (with a Steripen), light, and communication.

I've tried charging during high sun, rotating it, but can't get it to charge at a 60w rate anytime.

Great item for charging cell phones while camping in a tent.
