I wouldn't say it's bad and the price is very good, it's sturdy and well built and it definitely works with my 3 lithium batteries. It's easy to set up and comes with a good set of adapters. Compact for storage. It's just pretty bad compared to two of my Jackery Solar Saga 100 panels which actually bumped the output to 100w and my Bouge RV 100w foldable panel bumped the output to 87 which is pretty good if you put it that way remember this is New Jersey. The maximum I could get from this panel, by placing it in the same spots as the others for a few seconds and making sure the clouds don't roll in, is 67 watts. I nested the panels by moving them to the same spot and angle and it still worked a lot less than the others. I played around with it for a good 40 minutes, rotating and comparing the readings. I think if I hadn't been spoiled by other panels I would have been pleased, but that would have meant almost 1/3 more loading time compared to the Jackery panel. Yes, the Jackery costs about $120 more, but the Bouge RV costs the same as the IClever.
