I received this panel to use with my 3 portable power stations. The panel comes with 10 adapter plugs and the user manual actually lists the 3.5mm adapter plug as one of the 10 plugs, but after receiving 2 panels it doesn't come with this plug adapter of this size (3.5mm). Of course I need that for one of my power plants, so it's a bit annoying. It comes with almost every other adapter size known to man, except 3.5mm. The solar panel itself works well and the light meter works well. Remember that the light meter only works when it is flush with the panel. When you release the button, it folds up and stops reading the light level. The panel had no problem charging my Enginstar 300w portable power pack (5.5mm x 2.1mm plug). However, if you have a Necespow or DB Power brand power station, they use a 3.5mm plug and you will need to buy an adapter to use it with this panel. I also received 2 panels and both come in their original slim flat boxes. There is literally no packaging protection for them. My second device came with a box that was pretty torn. Both of my panels came in boxes that weren't even sealed with tape. Overall, I still recommend this panel because you can easily add more panels if needed.
