Producto bueno, no he tenido la oportunidad de usarlo al 100, pero ha pasado las pruebas

Good value for the money

Please keep in mind that when it comes to solar panels the wattage rating usually equates to what is possible under laboratory conditions and just about never can be recreated in the real world. With that said, here's my review:As the headline reads, this is not exactly 'light'. Surely easy enough for one person to move around and deploy and it folds down to a size that was easy enough to find room for behind the front seat of my truck. Since my RV already has a decent MPPT charge controller I decided I'd add on to the existing one (besides the included controller that came as part of the 'kit' HAS to be protected from the elements (direct sun & moisture) so was of little use to me to use along with my existing one.The 'kit' came with a ~10' cable that has connectors on both ends to use hooking it up. One end has a SAE connector that plugs into the panel and the other end I cut off and replaced with Anderson connectors. A word of caution here: Due to SAE's 'keying' the +/- wires will reverse unless a little SAE-2-SAE adapter is used to change the polarity of the wires.Given I don't live in a LAB and I'm above the 45th I did not have high expectations for this panel. However it was a bright and sunny day in May and with a clear view of the sky (not a cloud in it) I set up the panel in my front yard. My existing solar panel (68W) was putting out ~40W when I plugged Dokio in parallel to it.The solar panel wattage reading on my phones Bluetooth app went from ~40W to ~210W after plugging in the Dokio - showing that the Dokio 220W panel was providing ~170W of the ~210W total.IMHO: not bad!I plan on adding a fused SAE connector on my RV and keeping the panel behind the front seat of my truck. While the included cable is far to short (I ordered a 25' SAE-2-SAE cable from Amazon) this will come in handy to add more 'juice' while I'm out in the wild - which is mostly what I do when I go out camping, I rarely have RV hookups even when I camp at official campgrounds. (I'm a boondocker!)Granted, had I not already had a better solar controller installed I could of wired up and installed the one included in the kit. Sure, it is fairly basic but at least it has different battery type settings so you can match it to what your using.I should note that when my panel kit arrived all that showed up was the panel box, nothing else! I contacted Amazon which asked me to contact the vendor and within 24hrs they responded and 48hrs later a FEDX truck dropped off the rest of the kit! I'd say very good support from the vendor!To conclude I'd say that so far I'm happy with my purchase and the support I've gotten from the vendor. :)UPDATE (9/22/2022): I've tried using the panel a number of times since purchase. As an example, I currently have it set in my front yard attempting to charge a power brick. While @ 9AM the sun is low in the sky the entire panel is 'lit' with sunlight but only putting out ~50W of power. As a 'control' I also plugged in a 100W panel and only got 25W out of it.

I bought this solar panel and charge controller to charge the batteries in my off-grid travel trailer and they work great. They start charging even before the Sun is fully up in the sky and by 10:00 am are pumping amps back into the batteries. I especially appreciate the USB ports so you can chagre your phone, smart watch and laptop. Just remember that the watt rating of solar panels is probably set at noon at the Equator so you're not going to get the full 200 watts but that is same for all solar panels. Dokio's 200 watt solar panel is noticeably lighter that another brand I have so that is appreciated.

I would give this 5 but I think the controller could be higher quality and the cables need to be a bit longer. However, it seems to all work on my trailer. I have a solar panel on the roof. This panel is a nice addition to allow me to move the unit into direct sunlight. It's also a good backup. I wish the cables were longer. I have to buy an extension cable for this. The controller is pretty much the basic of basic controllers. it works and does the job but I have read some reviews that it's not that great. So far it's all good though.
