## Description

desertcart.com : DOKIO 300W Portable Foldable Solar Panel Kit with Charge Controller | Folds to 19.3 x 37.4 in and weighs 15.2 lb; USB ports; for 12V batteries, power stations, RVs, and camping : Patio, Lawn & Garden

Review: Nice Lightweight Solar Charging Kit - Very nice set of solar panels just wish they included a set of stands because they are pretty inefficient without putting them on a proper angle to the sun. The company sells the stands separately. The stands they sell are alright but where they weld the rods to breaks easily. I posted a bad review on the stands and the company reached out to me and are sending me another set so they are very receptive to the customers needs. When used at the proper angle these panels deliver. They put out a respectable 8.8amps @ 22.5 volts open circuit. I made this setup more efficient by using a 12gauge SAE extension and a portable MMPT charger as the one they provided is adequate but I need every watt these panels deliver to recharge my Ham Radio battery’s out in the field and and MMPT charger can keep delivering power even on cloudy days . The panels are nice and light so if you have to trek your gear by carrying it a distance this is great and was my main reason for purchasing this brand. They are very thin and folded up are only about 2” thick and about 9 lbs with the controller and cables. They have a nice storage compartment built in. If I can make one suggestion to the company to make this the greatest system. Build stands into the panels backs like a photo frame has so you don’t need a set of stands. It would make these truly light and an even better product. These panels charge a 12.8 volt 20 Ah LIFEPO4 battery from a shut off voltage of 10.1 volts to a full charge in about 2.5hrs in direct sun light. The only gripe that I had was setting the provided PWM charge controller to B4 so it could charge LIFEPO4 batteries. Very confusing but I finally did it. This is one of the reasons I purchased a nice MMPT charger dedicated to charging this type of battery. You can’t go wrong buying these great panels. They also provided a nice set of accessory’s with these panels including a set of alligator clamps and multiple charging plugs. Very well thought out accessories.
Review: While not exactly "light", it does provide a decent amount of wattage - 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 desertcart) 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 desertcart 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.

## Features

- 【BIG POWER, STILL PORTABLE】 Folds to 19.3×37.4×1.1in and weighs only 15.2lb, so this 300W panel packs serious energy yet remains slim and easy to move, mount, or store for RVs, vans,
- 【SEPARATE CONTROLLER FOR SAFER CHARGING】 Equipped with a standalone PWM controller that protects your 12V system from reverse polarity, overcharge, overload, and short-circuit—and can be replaced or upgraded later if needed.
- 【LONG REACH FOR FLEXIBLE SETUP】 Includes a 9.85ft (3m) cable, allowing you to place the panel in full sunlight while keeping the controller or power station safely shaded for cooler, safer operation.
- 【KNOW YOUR POWER STATION’S LIMITS】 Some power stations restrict solar input (often 100-200W). Even under full sun, a 300W panel cannot exceed your unit’s own cap—this is normal design, not a defect. Please check your model or message us for confirmation before ordering.
- 【USB CHARGING WHEN YOU NEED IT】 When connected to a 12V battery, the dual USB ports provide stable power for phones, lights, and small devices. Even without a battery, they can still work in sunlight for emergency top-ups, though current may fluctuate.
- 【MONOCRYSTALLINE EFFICIENCY, BUILT FOR OUTDOORS】 High-grade mono cells deliver better conversion efficiency and reduce mismatch loss. The panel surface is weather-resistant, but avoid leaving the fabric case in heavy rain or strong sun for days to extend life.
- 【COMPLETE BUNDLE READY TO GO】 Includes the 300W foldable panel, separate controller, SAE/XT60/Alligator clips, DC5521/5525/35135/6440 adapters, 9.85ft cable, storage bag, and manual—a one-stop kit for camping, RVing, or emergency backup.

## Questions & Answers

**Q: Is the solar charge controller compatible with "LiFePo4 chemistry" batteries?**
A: Yes, but it depends on your battery setup. the DOKIO charge controller included with the 200W foldable solar panel kit can be configured for LIFEPO4 batteries (battery setting B03).  But, the manual only describes usage for a 12V LIFEPO4 12v 4s setup (4s = 4 cells at 3.2V each, 12.8 volts in series).   This is a solid little 4-stage PWM (Pulse Width Modulation) charge controller.  PWM charge controllers typically run 80% efficient.  It is free with the panels so it costs you nothing to determine if it meets your needs.  The more expensive MPPT charge controllers typically run >95% efficient so if maximizing the amount of usable power from your panels is important you will want to upgrade to an MPPT controller at some point.   

 

DOKIO charge controller details:

12v 20Amp
2 USB ports (5v max 2A) that can be used without battery attached
3 battery type settings B01, B02, B03
Lead-Acid
Setting B01 = charges at 13.7V
Low Volt cutoff = 10.7V
Low Volt reconnect 12.6V
Lithium Ion 3s (3 x 3.7 V = 11.1V)
Setting B02 = charges at 12.6V
Low volt cutoff = 9.0V
Low volt reconnect = 10.5V
LIFEPO4 4s (3 x 3.2V = 12.8V)
Setting B03 = charges at 14.6V
Low volt disconnect 10.0V
Low volt reconnect 12.0V
 

PWM vs MPPT Efficiency comparison (eg: panels generating 17.7V x 9.2A = 163 watts)

PWM controller 80%, 163watts x .8 = 130watts usable
MPPT controller 95%, 163watts = 155watts usable

**Q: Can i charge lithium batteries?**
A: Yes. Mine puts out about 15 amps max

**Q: Is it plug compatible with any portable generators?**
A: SAE connectors aren’t great, 10AWG is small dia, but the included XT60 can connect to many “solar generators” (including AC200 from Bluetti) which are more-accurately called “power stations”. Review by Bob Wells is laudatory. More than enough “adaptors” included.....

**Q: Can this be connected directly to a solar generator?**
A: The panels are connected to the controller with SAE (2 flat). If you are looking to directly connect them to a portable generator, you will need to purchase an adaptor.

### ⭐⭐⭐⭐ Pretty good solar panel so far...
*by G***R on December 24, 2023*

I've been looking at this solar panel for quite a while, and waiting for the price to drop. Just before Christmas 2023, it went on sale with a coupon and only cost about $85. That was a good enough deal for me. The unit itself is decent, but a bit big. It measures a little over 2 ft by maybe two and a half feet when it's folded up but at least it folds flat. There are handles on the outside as well as a storage pocket for the wires and the little controller pad when using for charging 12 volt systems. I hooked this up to my Jackery portable power system. I then tried different places to set it to charge. I tried in my backyard and with one half of the dual panel shaded, it was charging at about 12 to 14 watts. When I put it on the roof of my car in the driveway, it was charging at 27 watts. I tried putting it inside on the rear luggage cover of my Subaru, with the tailgate closed, but it was only doing about 7 or 8 watts. I put it in the front window of the car, facing the sun, sort of like a sun shade, and it was pulling about 14 or 15 watts into the jackery. As long as this holds up, I feel it's a very good bargain and a very good item for when you need to charge your portable power bank or even keep it on your car as a battery tender or battery charger. I hope it lasts for at least a few years. At over $100, I didn't feel it was a good enough bargain, but when it went on sale I felt it really was a good deal. Let's hope I'm not proven wrong. Only 4 stars because of the price point. Also, I wonder about the overall strength and lasting power of the solar panels. Sometimes it sounds like they might crack if they flex a little bit too much. Also not sure how well it would do in damp environments. The box itself that it was shipped in had a big logo on it stating to keep it dry.
