DOKIO 200W Portable Foldable Solar Panel Kit, Compact 20x26.4in Design 9.7lb with Standalone Controller and USB, Monocrystalline Charger for 12V Batteries, Power Stations, RV Camping Emergency Use

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.

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 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.

Just took the unit out for a 3 days camp trip. Charged our cheap 300wh generator in 2.5 hours. Comes with all the connectors necessary, so its all plug and play. For the price, you can't beat this portable solar panel. We've only had the unit for a short time, so we so don't know how durable it is. We got the extended warranty, so we are not worried about its durability. Only improvement we could think of, is it need tie down points when unfolded, so we can secure it to our rig and not worry about it flying away.

glad to say there is nothing wrong with the panel i received, it works, light weight and easy to move. not getting 200 watts out of it. but from an hour ago to now it has gone from 54 watts to 116 watts without me moving it. might be able to get more if i figured out the perfect angle and direction to place it. does not have stands on it. obviously the sun has moved to a better position for it to get more power. the charge controller could be better, but it is not what i plan on using for my set up. I bought a better charge controller that is a MPPT not a PWM. I was not expecting perfection due to the price. it is the cheapest solar panel for the watts it says it should be. I am getting more than 100 watts so i am happy for what i paid for it. I ordered another brand of portable panel and will see what i get from that when it arrives. it is rated at 100-120 watts and had a $50 coupon so i got it for about what i spent on this. hopefully i get that some watts out of it.

Perfect form factor, extremely light and works very well so far (I don’t use supplied cables or solar inverter, but do use the polarity reverser). Also I only use it for camping occasionally, would not recommend for full time nomads as the plastic on these just can’t hold up to constant uv exposure (ironic ha). But for weekend campers, this is a great portable setup and of course much more manageable than a suitcase solar panel.

I usually get 50-85 average watts from this 200w setup... easy to deploy, free energy!

This is a great alternative to installing regular solar panels on our van. It has come in really handy during our travels. At some point, the solar charge controller stopped working and the seller sent me a replacement very promptly. They also sent extra cables and connectors. Very pleased!

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

Práctico, funcional, buena tecnología

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.

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.

The size and portability is a definite plus for these panels; they fold up and hide quite nicely behind the couch in my RV. They do the job of charging my battery, but nowhere near the claimed 200 watts. In direct sunlight I can count on about 100-120 watts.
