DOKIO 220w 18v Portable Foldable Solar Panel Kit (29x21inch,11.7lb) Solar Charger with Controller 2 USB Output to Charge 12v Batteries/Power Station (AGM, Lifepo4) Rv Camping Trailer Emergency Power……

I got the 110w 18v portable folding solar panel kit. It was a very good price compared to what else is out there. Packaging was fine. The quality looks good. I also got a 20 foot Dokio XT60 extension cable so my power station doesn’t have to be so close to the solar panels. I set up this kit to charge my Bluetti EB3A. The connections were easy. The EB3A was just above 50% charged at the start of charging. The solar panel was in good sunlight and the charge rate was about 65w. It charged the EB3A the rest of the way up to 100% in about two hours. So far it works great and I’m happy with it. This is a good deal.

I own the 110 watt portable solar panel suit case. I have read many posts talking about how this panel will not produce a good charge or just half of the rated watts (so for my case I would expect to see 55 watts). So I decided to test it today. I live in Florida and its almost noon so the sun is at its peak. Yes that is snow on the ground we just had the winter storm come through the panhandle. I have it in direct sunlight and propped the panel up to create a decent angle. I am receiving 13.9 volts by 5.8 amps. This equates to around 80 watts of solar coming in. I am using the 110 watt panel and was hoping for close to an 80-85% efficiency, but I feel like the 80 watts is fair amount of wattage for the cheap price of this panel. I would buy again, but would rather buy the larger 220 watt next time.When you lay it flat on the ground it does pull in 55 watts. This should be expected due to the angle being less efficient.Update:I recently received a Bluetti AC 180 with a built in MPPT Charge controller. I used the adapter that came with the solar panel plugged it directly into the unit and I received the same wattage as I did when using the PWM charge controller connected to a battery.I also have a 100 watt hard solar panel and did some testing with that. I did receive higher wattage (around 15 more watts on average) from the hard/heavy/not really portable panel. So you need to decide how important the portability is.My main usage will be when camping on my boat or to help top off my power station at home. This will still help to charge up my power station during the day so I can use the microwave when I want and possible run my mini-fridge for a few days. Still satisfied with the purchase but still wish I just bought the bigger portable panel.

We have had this for over a week. We just today mounted it on our porch awning which has a 10% tilt angle which isn't the best, but it's better than laying it on the ground. In the many previous days of testing, we had the panel on a 10+ degree tilt toward the bright sun, and got a max of 60+ watts only. After a few days of the same, we blocked each individual panel to see if ALL the panels were registering. Using our sine wave display of our solar battery, the end panel (farthest from the panel that has the pocket) didn't even register more than a 5w input! We then blocked the remaining three panels and it registered between 40>50+watts. So it seems one of the panels might be not functioning correctly.... has anyone else had this problem? In bright sunlight with a clear sky, the most we registered as a whole, was almost 70w but that was a very rare and very occasional 70w. I'd like to know what others are getting! Still is nice to be able to charge the solar battery enough to power hand devices and we have even used the panel to charge household ceiling lights and more. As forementioned today we finally were able to permanently mount the solar panel on our porch awning, and with still bright early afternoon sunlight it is registering NOW a highest input of 30-40watts to our battery, which is a EnginStar 298Wh pure sine wave 300W power station.UPDATE 22NOV2022: We decided NOT to take down off the outside awning and days ago recevived up to 10+inches of snow. YES, the solar panel was covered with abt 2+" of snow. On the same day of the WNY-Buffalo snowstorm, we plugged in the solar battery to charge it, and tho it was tiny single-digit watts in, the battery was charging off the still snow-covered panels! The next day we think a bit of the snow melted as the in-wattage increased - a very TINY bit - but nevertheless: STILL charging! Now we are at 2days after the snow November, and as the sun is shining down on the panel, it is STILL charging and at a low double digit wattage. It's been covered with snow for 2days but still charging our battery! Eventually, the 300w solar battery was charged in three days!UPDATE 7Dec2022: Using a different 300w solar battery with a "builtin MPPT", today on an overcast day we saw the HIGHEST wattage input from this solar panel since its purchase: almost 96w!!Once Spring decides to stick around permanently, we will be removing the panel to angle it correctly. Another plan would be buying a 300w folding panel to replace this 220w panel & using this as a standby, and properly angle the new 300w panel properly to the sun. Will update with new data once that is once. The newer battery we picked up last Dec 2022 is the AMPROAD Epic 300 Power Station & gets a higher charging wattage consistently than the older EnginStar batteries. I also purchased last year a 600w solar battery BUT it kept going to sleep so it was reappropriated to a family member who could use it and bypass its sleep mode as is very electrically-savvy, moreso than me.23Apr2023: Purchased and just delivered earlier today a DAY EARLY my newest folding solar battery: 300w to supplement my 220w panel I've already had for months. Overcast/Windy today but went out anyways to test it with my AMPROAD Epic 300 Power Station and even on an OVERCAST day was inputting 100+ watts. Very happy and hoping that when installed next to the 220w, will give me the charge of the Sun I've been wanting. Only complaint on this 300w panel, it had a few scratches on one panel.

These 220W panels work great. Just camped for 6 days with our travel trailer. We have two 6v golf cart batteries, and at the end of our trip, they were still at 13.4v. In direct sun, we could get up to 7 amps, and even in no sun, we were getting around .7 amps. They fold up fairly small and are lightweight. The controller works great as well.
