I was skeptical but have been pleasantly surprised. We have used it a half dozen times and consistently were able to get 240-270 watts in partial tree cover depending on the time of day. I have added longer cords to be able to set it up on top of the trailer or out away from the shade of the trailer.

****Update 4/30/24
I requested a replacement. Amazon sent me new panels. The seller also reached out to me. Panels were delivered the next day and so far they work great. They charge my Lifep04 100Ah battery and I can run the camper AC on a sunny day with no problem while keeping the battery charged.
Update****
Solar panel burned after the second time charging a 12V LifeP04 battery 100AH and a 2500W load….
See last picture. I ordered a replacement will update when I get it and see how long it lasts…
************
Not bad, they are easy to move around. No back legs to hold them upright. No holes to hang them from a wall. The Controller is not the best, but a better one to take advantage of the panels.
Tested them for an hour, battery went from 11.9 to 12.6 V within 30 minutes on a cloudy day. I haven’t tested this panel fully yet. Not bad for the price I paid.
The connections are simple, however I had a reverse polarity within the system and I had to switch my battery cables in order to make it work. No a good thing that’s why they send you an adapter. Quality seems good, they are flexible however don’t bend them to much or they will crack. Cables are short, order extra cables….

Set this up in at 43 degree latitude in late March around 5C outside. Panels work best with strong sun but low temperature. So the 100W rating may be achieved if you have tropical noon sunshine with artic temperature.
Got ~65W max in early afternoon when angled to the sun at 43 degree latitude at 5C. Flexible cables and connections for charging 12V batteries and battery power stations (e.g. Goal Zero) Fairly light weight and portable, the built-in charge controller is functional
My only concern is the durability. The whole setup is a sort of floppy and the panel visible bends when propped up on an angle. It wish it was more study or has a kick stand to help it stand up. Flexing a bit won’t hurt generation, but repeated flexing may break internal wires and cause it to not work.

The Dokio 110 watt system I set up worked well in cloud and sun. I built a simple plywood support frame and let it go to work. Charging ranged from 24 volts in full sun to 13.5 low in full cloud. It was a good unsettled day to test the unit. I had two 90 amp hour deep cycle batteries hooked up in parallel and my IPad which was at 16% charge from start time. The batteries started with a reading of 12.9 volts and after after 5 hours were 13.5 volts. The IPad was at 75% charge after 4 hours. I also like the charge controller readout screen. It keeps you informed of the performance and constantly monitors the pv output. I can see that we will be able to extend our RVing off the grid considerably without worry about losing power or resorting to a generator. A 200 watt system would likely keep the batteries fully charged but for us, this will do the job nicely. Super happy so far.

Panel is good. Not lite, but reasonable for its size. Easy to transport and store. Good number of connections. The cable that comes with it could be longer – it’s really too short – had to pick up an extension cord for my purpose. REALLY would be good if it came with a pop up stand like other portable versions.
I wanted this for an Ecoflow Delta Pro with an extra battery. There have not been sunny enough days to do a proper full test, but on a day where the sun was in and out and not fully clear the panels hit 200 watts (see pic).
Overall, impressed with the purchase for the price

This works well for charging up a power station like bluetti or jackery. Be aware that it isn’t designed to charge through the inverter for that purpose. It does come with the correct adapter cord for plugging straight into the solar panel for that pur though. My problem with it is that I had to purchase an additional cord (XT60 to SAE) so that I could use the provided inverter and plug into the solar port on the outside of my rv. It only comes with alligator clips for RV battery charging even though it claims to be compatible with RV charging. Additionally, the alligator clips don’t spread far enough apart from each other to put on a dual battery system. It really should come with the XT60 to SAE cord to be a truly complete package as claimed. Make sure to order yours when you order the panel if you have a SAE solar charging port on the side of your RV. Note: I can’t speak to longevity of the panel yet. But I will say that it seems to produce in the expected range so far.

Comme les explications sont seulement en anglais,l’installation est difficile. De plus, j’ai dû acheté des fils supplémentaires pour connecter le panneau à la batterie Ecoflow. De plus le colis est arrivé à une autre adresse.

I bought it to charge an 1,800W class of power station. It is vary convenient that the various size of DC connectors are provided for. There are no special problems so far, and performance testing has not been done yet.

This review only applies to the panels themselves, I do not use the rest of the kit.
First off, for those saying these don’t product 300w, you need to understand solar panel ratings. They will produce 300w in more or less perfect conditions. So for example mid day late summer clear Texas sky pointed right at the sun absolutely they produce 300w (each set). I only use the panels, not the other stuff as I have a parallel cable setup with a pair of these panels and in the right conditions I get a full 600w out of 2 of these into my AtemPower DC to DC charger / MPPT charge controller. Your limitations are going to be environmental conditions, and your charge controller / power station setup. I run my camper electrical, 12v fridge, USB chargers, laptop charger, CPAP fans etc… and this has no problem keeping the batteries recharged / topped up.
My only issues, and they are kind of the nature of the beast as it were are…
#1. No included / build in kick stands to set the panels up to actually face into the sun directly. No big deal. Dokio has them available through Amazon, just don’t forget to buy them, and carry the hex key with you… #2. Water resistance. You are NOT going to be charging up in a deluge no matter what, and Dokio claims their materials are water resistant, but immersion can be a problem. Keep the connectors pointed to the TOP of the panels, and if ponding / flooding is a possibility take them down and move them inside. Simple enough right?
I opted for portable panels instead of roof top mounted panels on my camper to allow me to move the panels as the sun moves to keep them oriented to the sunlight to keep charging going. These are great for that, until some jacknugget pulls his big a– fifth wheel just to your south giving you nothing but shade. Not the fault of the panel, and remember, portable, just move them!
Liked my first set so well that I did get the second and built the parallel cable, so instead of 300w coming in at 18v, I now have 600w at 18v coming into my MPPT controller. (33-1/3 amps).
This came with a simple MPPT charge controller, and a bag full of adapters for various power stations, none of which I use and I am not reviewing them.
My only desire for any kind of upgrade is, I wish they made these in a 500w capacity, so that I could pair up 2 of them into a 60 amp controller and get 1KW into my camper, 600w is good, 1KW I can at least run AC for a while on…
