Out of the 5 solar panels I tested today, this one did not perform as well as the others. I was only able to get about 88-90 watts of power at around 18.5 volts. And with that I was only able to get about 4.9 to 5 amps of charging current. It's certainly not a slouch, but it was still slightly below specs. I tested this panel using the DC connector with a DC to MC4 adapter cable.

The build is solid, and the support legs do their job well. What is most interesting is the choice in cabling options this panel offers. In addition to the standard USB/DC output box typically found on most portable folding solar panels, this panel also has an Anderson connector cable wired directly from the panel. You are also provided with an Anderson Y to DC cable that will allow you to easily connect two panels in parallel. There is a DC to DC cable with a collection of DC adapters to fit most any portable power bank or laptop charge connector.

Like the panel itself, the cables are fairly high quality and should hold up over time. I am a bit disappointed in that this was the only panel I tested that fell a bit short of specs, but it was also the last one I tested and perhaps the clouds were a bit thicker. It still did well, and I have a feeling that under direct full sun this panel will hold up well.

Great product. I bought this solar panel along with the Enginstar 300 and I am totally impressed with the quality, design and easy to use. It is extremely mobile, tough and reliable.
