100W Portable Solar Panel for Power Station, Monocrystalline 100 Watt 20V Solar Panel Foldable Charger for Camping, 23.5% High Efficiency IP68 Waterproof for Outdoor RV Trip

Many adaptors, easy to carry, charged phone, supports could be a bit sturdier, but they worked. Nice design with pouch.

Only tested this briefly the day I received it. Easy to set up. I wonder how durable the fabric cover will be out in the field. During my test charging a solar generator, the generator showed 69W output from the panels under mid afternoon clear sky.

This folds up small, easy to pull out and set up. We charged out phones and power banks at a pretty good rate of speed. It is helpful to note this device only changes it does not store power, but it will charge your portable batteries.

Put this out in good sun (but left it mostly laying down, so didn't have it at the ideal angle). Each time I checked my controller I saw over 4 amps constantly (checking every hour or close). I even pulled out another meter to verify the controller and it matched. My controller is MPPT and takes in power like 18V 3.8A and converts it to ~14V 4.4A (converting the extra V into extra A), but it's still giving good power for the imperfect conditions. I recently tried another folding panel labeled "15 watts via ~15V 1A" and never got even 0.4A from it (with the power dropping under 0.2A as it warmed up in under 30 minutes), but this says "100 watt via ~20V 5A" in it's specs and getting over 4 output on my controller is ~75%. I also have panels on my roof and after they warm up I'm often getting ~80% of their labeled power (and they are more at the ideal angle etc), so I'm really happy with what I'm seeing from this one. I've seen some reviews of panels with some just showing 19V on a meter, but that's not telling you the power (where you need both V and A measurements).As far as little details, there's a few things I've noted on this I like better than some others. This has the MC connectors coming off the panel (that aren't so good for constant connecting & removing), but does come with a 4 way adapter to go from them to several jacks on "solar generators" and more (I only wish they had the more common SAE connector). The wires on the back of the panel are aimed towards a panel edge to go further, another panel has the cable aimed towards the middle of it and I always have a 180 bend in the cable that seems a poor way to have it. I also find this easier to handle with just the one fold during setup and take-down, another with multiple folds has a section flop one way while positioning another etc. I'm not sure I'd leave this out in rain despite them saying "Waterproof" with the cloth bag for the wires etc. The manual notes "The panel is waterproof, but not the connection box, so be sure it dries out before use if it gets wet". That's about the only concern making me look at others for the best.

I specifically wanted a panel that is less than 45 inches in length, so it can fit on a window of that height. This product is actually 48inches long when fully unfolded. It doesn't fit, I'll have to send it back.
