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…

If looking for an easy to manipulate set of solar panels these are work a look. I am very happy with them.

works great but does not have any way to support and angle at the sun, panel is flexible so bends if just leaned against something with just top contact

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.

Box was damaged but no damage to solar panel Looks like a nice kit Haven’t tried it yet .. will update when I do

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

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.

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.

Great panels, good output power as published in best case situations! Sunshiny day, open circuit 21.4vdc dead short 14.6 amps. Great panels but not for a permanent solar powered situation. Weekend, boon docking, Not sure I want to get them wet…. mainly to keep my frig running and a little charge to my 400ah LiFePO4. For the money…here’s a good deal
