    • Not fast, but does work.
Color: 40W
Not as powerful as you would want. You won't be charging anything very quickly with this. But it does work, is built sturdy, and is ok for fun, but don't have high expectations on charging fast.

    • Decent Design, Super Disappointing Output
Color: 40W

I bought this as a gift for my husband who was super excited when it arrived. We tested this panel under ideal conditions (clear sunny skies in Virginia), and it consistently peaked around 10W - nowhere near the advertised 40W panel output or 18W USB-C port rating. Using a USB-C power meter and protocol analyzer (photos attached), we saw peak output just over 10V, never exceeding 1A, and no support for USB-C PD (just QC 3.0). The USB-A port performs similarly. In more normal conditions, output drops to 5W or less. That said, the folding design is relatively compact and well thought-out, with the electronics tucked cleanly into the edge, better integrated than the boxes some panels use. If the performance matched the design, this could be a winner. As-is, it's not very useful. ... show more

    • Good: 20 watts from each of the 2 USB ports
Color: 40W
Works pretty good but be advised: You can only get 20 watts from each of the two USB ports. This means for a single input battery you'll only be able to take advantage of 20 watts of power coming from the panel.
