DOKIO 300W Portable Foldable Solar Panel Kit with Charge Controller

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 becomes a joke. I directly check the panel by multi meter, it read 19V DC, 0.5 MA, the resistance out of range. Seems no nobody can help.Story continue: I contact the seller and send a few photos to demonstrate the issue. The seller send a new panel quickly. And the new panel works well. Issue closed well. Many thanks to the seller, I am happy now.

Product is great. However it is only a 160W unit, not 300 watt. I did order a 160 watt solar panel. Price and delivery were great as well.

Arrived quickly. Upon initial inspection, the panels had some very light scuffs on them. Doesn’t seem to affect function. The cable on the panels has one type of plug. There’s a 6’ cable that plugs into that with an xt60 male at the other end. This plugs directly into my big station. There’s another short cable with a female xt60 that plugs into the first cable. It has a barrel type plug at the other end with an assortment of barrel plugs to fit various power stations. None of these fit my small station. Sad… There’s 2 other cables. One with alligator clips and one with bare wires. These plug into the charge controller out for a battery. I have not tried that. I had a cable with my small station that had Anderson plug on one end and the plug that came off these panels on the other. Lucky me. I was able to get 180w with very thin cloud. The panels don’t have legs for propping or eyelets for hanging. You’ll have to lean against something.

Subject: Mechanically Unsound – Logic Works, Hardware Fails"I am throwing this controller in the garbage. While the internal logic technically worked—I measured 19.7V at the solar cell terminals and was pulling 7.2A at 13.6V midday—the physical build makes it useless.The connectors are the primary failure point. They are not mechanically sound; the cables constantly fall out, making it unreliable for any real-world environment. I have invested in a Renogy Wanderer 30A with the BT-1 adapter to get a stable, professional-grade connection. Because this panel is rated for 220 Watts, the new Renogy controller should significantly increase the harvest percentage through superior terminal conductivity. Fingers crossed. I will update once the new system is live.
