折りたたみのソーラーチャージャーが欲しく、値段が安くて軽かったこちらの商品を購入。ポータブルバッテリーの充電に使用しました。
80wということで、容量として足りるのかが不安でしたが、3月の晴天時で30wから40wの発電量で、庭仕事をしている間にしっかり充電できていました。そもそもポータブルバッテリーなので今のところ車中泊で使う程度であり、シガーソケットから充電(15wぐらいでした)もできるため、私としてはこのぐらいの出力で問題ありませんでした。
ちなみに私が使っているのはsu○okiのポータブルバッテリーですが、ソーラーチャージ用の端子がこちらのものと違っていましたので、ワニ口クリップを追加で一つ挟み、DCプラグで充電して使っています。直接繋いだらもっとたくさん充電できるかもしれません。
インジケーターも付いており、大変良い買い物をしたと思っています。耐久性も今のところ不安は感じていません。

I’ll be honest. I really didn’t know what to expect with regard to performance of this type of setup. But, I have to say they work really well. Now I just bought these so longevity wise I don’t have that information, but I tested these as soon as the sun came out about 9:30 am. They were generating 21.8 volts at 13.8 amps equaling 288 watts! Nice! That’s a 90% efficiency right out of the box of their stated capacity. Incredible. They’re super compact for what you get. Lightweight, easy to store, a nice durable material on the outside for protection, and are somewhat rigid. Cons: When I first started looking at these I saw a picture showing supports behind it holding it up. NOT! These do not have back supports any kind. You are on your own for that. The cord seems just Long enough to be helpful. The charge controller is a lesser expensive 20a PWM but it is constructed very well with plug and play connectors for a very easy setup. Of course I’ll have to test the performance of the charge controller, with regard to actually charging a battery, so we’ll see. I’ll compare it with my MPPT controller and see if there is a major difference. But as it is, it’s a really good setup. I’m very happy with it and highly recommend.

This kit can charge a lifepo4 battery. Maximum charge current is coming from this cheap pwm charge controller, it’s only at around 14.6 volts max voltage from this controller with this solar panel. Which is enought to charge a 12v lifepo4 battery at 14.4 volts charging. The only trick to charge a lifepo4 battery more quickly, is to have full sun day on solar panels.
Best to invest in a mppt controller charger, but not totally necessary for a small solar panel setup like this. 14.4 volts in full sunlight on this solar panel to charge your lifepo4 battery fully. Make sure solar panel face is facing sun at 90 degrees to sun for best voltage.
These solar panels seem to work, but they are fragile. Do not bend them too much, I heard one making a slight crackling sound when bending slightly. Good to have or make a solar stand that supports this solar panel well so it doesn’t bend much. Like make a solar stand out of pvc pipe and carriage bolts to make a folding frame stand.
Nice to have this light weight portable solar panel. Does charge a 12v lifepo4 battery 50 ah pretty quickly. But better to buy another solar panel to get more juice to battery for when you have loads on battery, and for charging, topping off your battery much faster.
Too bad that all solar panels are only about 23 percent efficient or less. Can you imagine if solar was 100 percent efficient ? You could then run the whole World off of pure sunlight !!! Plenty of power comes from solar if We could get much more efficient panels, controllers and batteries. We need about 50 percent more efficient solar for it to really take off, and for a forever energy source.
Solar panels used in space by NASA etc. like on all satellites, work better in the coldness of space, if you chill a solar panel down in temperature you can get much higher charge current. Much More effeciency from freezing temps, on a solar panel.

Good panels but cloth may have UV issues. PWM charge controller is OK but does not provide max output. If this came with a MPPT controller I would have given it 5 stars.
I purchased this item thinking I might have to send it back due to questions I had relating to it’s quality and output. 330 watts with PWM controller for a little over $300 seemed like one of those “to good to be true” deals. I decided to give chance and ordered it in early November. After 2 weeks of snow and clouds, I live in south western Michigan, I finally got some sun today for testing.
One of the things that I was looking for in a portable solar panel was one that had the newer ETFE coating in place of the older, glossy, coatings that I have seen peel off in other reviews.
This model, FFSP-330W has the ETFE coating and improved solar cells. I ordered ASIN B07JPH4PHG and expected to receive the 330 watt solar panel. When it arrived it came in a box that said FFSP-320W. There was a small sticker on the side of the box showing that this was the ASIN B07JPH4PHG. I emailed DOKIO asking about this to make sure that I received the correct panels. They replied within one day and with one more email exchange with pictures they confirmed I had the correct unit.
Having read that PWM chargers are not the best I also ordered a Renogy ROVER 30A MPPT charge controller to compare the output to the DOKIO PWM charge controller.
Here is how I tested the panels and charge controllers.
I used two plastic saw horses from Aldis to prop up the solar panels at 30 deg angle for the low sun in Michigan this time of year. I also looked up the expected power from the sun given location and time of year and found that it is 1/4 to 1/3 of what the summer sun strength would be.
I took a 12v marine battery and hooked up both charge controllers along with a 12v heater that drew 11A.
I set all this up so that I could move the panel output from one controller to the other rapidly to compare output. I also put an Amp meter on the battery to compare panel output to what the charge controllers said.
Note that the ambient air temp was 40 deg F.
I was thinking that since the sun power was 1/4~1/3 the normal max strength that I would be lucky to get 6~7 amps.
With the DOKIO PWM I measured ~13V with 14A, 12A according to the clamp on meter.
With the Renogy MPPT I measured ~13V with 16A, 15.5A according to the clamp on meter.
Using the Renogy values I was getting ~200W.
The MPPT was definitely performing better than the PWM.
Then I decided to check the output with the panels flat on the ground.
By this time there was a haze across the sun and the MPPT output had dropped to 10A.
Placing the panels flat reduced this output to 3.5A.
BIG difference.
These panels are not as small as some of the fold ups but are perfect for storing in my RV and only weight ~15lbs.
I am VERY pleased with the panels. The PWM charge controller is OK, nothing special.
In regards to the material, RED edge piping, deteriorating over long exposures, that has yet to be determined.
I plan on buying some U/V protectant spray to coat the material and slow down any damage.
I would recommend these panels to anyone looking for a portable system but you should purchase a 30A MPPT charge controller. PWM controller that comes with the panels is only 20A. If you only lay the panels on the ground you will probably not exceed the 20A .
If you angle the panels you will go over 20A.
Also note that heat reduces the panel output so if you leave it laying flat on a surface in the summer it will heat up more compared to raised panels that can dissipate heat out the back.

Quality of the panel and the cables is top notch. Used the panel already a few times and it has kept my RV battery charged at 100%. If you camp off grid then this is a must purchase. The only negative thing that I can say, is that the instructions for the controller you can tell is written by a bot that doesn’t know English. Luckily, there are enough videos out there that can do a better job of providing instructions. Otherwise this is a great purchase. I do not regret it at all I highly recommend.

Easy to use controller, and simple setup. Just unfold panels and plug in. I tested the output yesterday under less than ideal conditions, and they were putting out 165 watts (I just laid them on the ground and didn’t bother to angle them correctly) I replaced another solar panel kit with this one by Dokio, and I’m glad I did. Great quality product with convenient carrying and storing setup. No terminals and screws to mess with, easy plugin. I should have bought this in the first place! Five star rating.

未だ未使用ですがテストしたら発電はしています。冬に本格的に使うつもりで購入しましたが期待出来そうです。
二つ折りで持ち運びに良い感じです。

Picked up this solar panel on sale to charge my water pump via a deep cycle battery . Works like a charm ! Very lightweight and super easy set up
