DOKIO 200W Foldable Solar Panel Kit Lightweight(11lb,28x20 inch) Monocrystalline(HIGH Efficiency) with Controller USB Output to Charge 12V Batteries (All Types: Vented AGM Gel) RV Camper Boat

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

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.

Parfait pour mettre dans le VR. Le contrôleur est assez basique, j’ai acheté un MPPT avec module BT. Mais le contrôleur inclus semble quand même correct après essaie.

We are putting our toe in the water with solar, and this was the perfect start! Pros: Light and easy to transport Complete kit, you really don't NEED anything else to charge your battery The charge controller is good quality and easy to use considering the low cost of the panels EASY to use, I am no expert, and this thing was up and charging in just a minute. Clamps and cables work well Charged my cell phone completely on a cloudy day using the USB port...cool Cons: Because it is a soft case, you need to be really careful not to bend the corners, this can damage the cells and lower the overall ability of the system. We laid our flat, then the first time a dog walk across it, we found a solution that would keep it off the ground. (see picture) The cable is a little short, so we bought an extension. It doesn't have the AMP output it should for a 200 W system, the highest we got was 7amps. Still for the price, not to shabby.

I'm quite happy with this portable solar charging kit that I'm using to supplement the on board solar charging in our RV. I would give this a 5 stars if it came with a longer cord from the panel to the controller. I did however purchase an additional 25' extension cord that makes this kit more useable for our needs. Folds up nicely. Fairly light. Fairly simple to operate. I haven't done a thorough check to see if I'm getting the charge it's rated for, but I know it's pretty good and really speeds the charging of my lithium battery.
