Reviewed in the United States on December 26, 2023
Actual specs:
I measured this unit putting 1.4 amps into my low car battery on a sunny day in December in Maine. That's about 18 watts in the middle of winter, pretty good for a 20 watt panel. That was before I fixed the wiring.
The label on the back of the solar panel has slightly different specs than the Amazon title. It says 25 watts max power. See attached photo.
Charge controller:
The included charge controller works well. It's an intelligent 3A PWM charger that automatically switches through 3 charging phases: bulk, absorption, float (trickle). It has an LED to indicate when it has solar power and what charging phase it's in. It will prevent over discharging below 10.8 volts and over charging above 14.4 volts.
At one point I thought my charger was broken and started looking for a replacement. A decent PWM charger like this runs 15-20, so it's a decent value. I later discovered the charger was fine, the problem was the cheap included wires (see below).
I was a little worried about the charger consuming battery power when there isn't any sun. Cheaper chargers use a little battery power overnight and on very cloudy days while waiting for the sun to come back. I wanted to leave my system unattended for months during our short and cloudy winter days without discharging my battery, so I can't tolerate much current drain when the sun is gone. Amazon didn't list the current drain when I bought it. I measured the charger's current drain with no sun at about 1mA. That seems pretty reasonable compared to 10-50mA with other chargers. The charger ships with a spec sheet, which lists the current drain as 1.5mA (see attached).
The spec sheet says the charger is made for Gel batteries. It seems to work fine on my SUV car battery though.
Cheap wires:
I measured my battery voltage while charging on a sunny day. 13-14 volts is normal, but I was only getting 12.4 volts. I thought the controller had gone bad so I tried another one. Same problem. I tried lots of things, went over all the connections many many times but nothing worked. It definitely had power coming from the solar panel, it just wasn't getting to the battery. Over a few days I did notice the battery charge increasing very slowly, but the charger kept thinking the battery was fully charged too soon and kept turning off (trickle mode) too early. I finally had the idea to check the battery voltage at the other end of the battery wires (where they connect to the charger). The charger was putting out 13.6 volts at about 1.5 amps, but only 12.4 volts was getting to the battery. That's 10% of the solar power being wasted by wire resistance! It was also enough to fool the charger into thinking the battery was charged and switching to a low power mode, which throws away even more of the generated power. It will still charge your battery eventually assuming you aren't using the battery for something else, but it will be slow.
I replaced all the wire with normal 16 gauge wire, and it fixed everything. I measured 13.6 volts at the charger and 13.5 volts at the battery while charging at 1.5 amps. It charges much faster now, and I can use the battery to power other things. I attached a picture of the cheap wires they include and some normal 16AWG wires I replaced them with. On the outside it's deceiving because the cheap wires look reasonably thick. But if you cut into it you'll see the cheap wires are almost all rubber insulation and have very little actual metal inside.

Waterproofing:
The actual solar panel appears waterproof and has white silicone around the edges on the back. However the charger is definitely NOT waterproof. It came with clear silicone applied along the bottom of the green connector, but that's pointless since the top and sides of the connector have bigger openings and were left unsealed. I needed the charger to work outside in the winter in rain, snow, ice, etc., so any water intrusion could easily freeze and damage things. You could always buy silicone and seal all the openings including the holes in the green connector where the wires attach, but then it will be a pain if you ever want to remove and reattach the wires later. I ended up opening the charger box and spraying conformal coat to waterproof all the electronics. Then I drilled a 1/8" hole in the white box to allow any water that gets in to drain back out. Takes about 10 minutes. So far it's holding up well to our Maine winter environment!

The wire does seem to be very light gauge for solar hardware but this is a low cost kit and I can replace the wire if necessary. I combined this solar charger with the same brand of battery in 20A size. I'm using it to power a remote security camera which does not have convenient AC power. This is the first time I've seen SAE connectors used for a solar application, my larger solar panels use MC type connectors which are a pain to crimp on to large gauge wire. I'm still in design phase for my application but this is a fun little charger project (even more fun if it had been wired "right" out of the box).
My father always said "check your work", I did and it saved my project. It's working for me so far. I'll update my review if pertinent data becomes known.
Happy Solar Power To You

im running a 12v pond pump with this, it works very well.
You can't just leave it on the grass in the sun, connect a phone charger to the USB port, and let it trickle charge/etc. You have to connect it to a battery, which is different from all the other ones I've bought. Just something to consider if you're planning to boondock or something with this.
