In my short time with the product it seemed to work well for charging the battery and supplying power from it – however – whenever the charge controller was so much as hooked up to the battery, it emitted an significantly loud, very very high pitched sound. When charging or at any substantial discharge current, it got even louder.
This was over 10khz, so not everyone can even hear that – but it was loud enough to exacerbate tinnitus. I suspect the sound was even louder at ultrasonic or near-ultrasonic frequencies.
These kinds of sounds are usually caused by “coil while” of the inductors resonating at the switching frequency of a buck or boost converter, the most common way of changing DC voltage. High quality chargers will mitigate this either through physical design or intentionally-ultrasonic switching frequencies.
The sound, to me, was troublesome enough that it rendered the product effectively useless for an outdoor solar lighting project, as I could barely stand to be outside when this thing was plugged in.
It may be perfectly fine for you if you can’t hear high frequencies, or you’re installing in an unoccupied space.
I’ll note that the solar panel seemed to be able to apply some level of battery charge even when not in direct sunlight, which I found impressive. My sole issue was the audible noise.

Bought two of them around 10 months ago, and they started to lose their charging capability for the past couple of months. In the beginning they were putting out 14.2 Volts and as of July, 2024 the output dropped to a total of 6.2 Volts; not enough to charge two Lithium batteries. Save your money, purchase a better quality solar panels.

No charging controller for DC-Input on power station for charging purposes.

I purchased this to power my patio shades that came with factory chintzy solar panels and NiMH batteries. Their particular designed KILLED the NiMH batteries so I needed a completely NEW solution. I paired this system with a 12V 6Ah LiFePO4 Lithium Battery and has worked perfectly for over 4 months. So I’m happy!!!

This is an excellent solar panel. Charges my auxiliary camping battery without any problem.
Customer service is top notch, friendly and competent.
Will do business with this company again

Works great but the diodes blew out day one will I will replace them for safety

I needed something to keep the portable generator battery that runs my home during power outage fully charged. I leave the power on and plugged in because it has remote start. This way during the cold winter and snowy nights I can start this from inside and trust the battery is fully charged.
I have the control unit under a roof so it stays dry. The solar is on that roof and I will end up having it off the roof soon so the snow does not over power it.
This works really well and after year it is holding up and doing exactly what it is suppose to do. It is just enough wattage and you could use the USB for small charges but I have not used that yet.

They definitely keep my batteries charged great deal for price
