Solar Panel 25W 18V 12V Bendable Flexible Lightweight,Solar Car Battery Charger Portable Trickle Charger with Cigarette Lighter Plug,Module for 12 Voltr Boat with 10A Charge Controller (25w sloar Kit)

Update:the kit had mismatched connectors, requiring a few low amp, bare wire to F DC barrel pigtails. I requested them from the seller but they opted to refund $10 so I could pick them up myself - a 5 pack was around $7 including shipping. I recommended they upgrade all of their kits accordingly to make their and customer’s experience better. I’ll let the new customers take it from here.Also, my battery was at zero. The car is in a shady area but it still collects about 1.5v/day with a direct battery to panel connection. I won’t be able to test it while connected to the controller until I get my pigtails.First Impression:The individual components appear ok.As others noted, the panel only has female DC/barrel connector out and USB. The two included connectors are male barrel to light weight battery clips and male barrel to male cigarette lighter. The charge controller only has bare wire inputs.Although, I was tempted to cut the ends and be done with it, I wrote to them requesting a female barrel to bare wire connector for each bare wire connection - my controller has 3 (panel, battery,light) - so I can hard wire them once for future plug and play with the existing male ends. Additionally, I highly recommended they update their kits accordingly. It would save them and customers a lot of frustration.Meanwhile, I bypassed the controller and plugged the male end of the battery clip connector directly into the female connector on the back of the panel because I need to charge my car battery. The panel is working better than expected under trees.Time will tell if they honor my request for female to bare wire pigtails.

I should have read the reviews on this item before purchase. Yes the wiring and connections are like a kit but the major problem was the voltage from the solar panel in full sun was only 4.3 VDC. Considering my use was to maintain a 12 V battery of course it was useless. It may have been some error in the terminal block which has a plug output plus a USB output. In any event 4.3V will not charge an iPhone etc and certainly not a 12V battery

I like this set-up, but I haven't had a real use for it yet

I use this to trickle charge a 100Ah deep cycle Lead Acid battery. I use the battery on and off to charge phones, run laptops, etc... in my truck. So far, this has kept the battery topped up since it was installed 4 months ago! This in spite of the fact that it was winter and not nearly sunny every day.Solid product, but as with anything it will only perform to your expectations if you design your project in anticipation of weather, power demands, etc... do not assume that this will provide 50W 12hrs a day all year round, I bought this knowing that I'd need at least 30Wh per day minimum, and so far it has surpassed my expectations.

This really is very powerful to do much of anything other than maybe maintain a battery. I used the USB port to try to charge my phone in full sun and it took over 8 hours from half battery. Hooked up a 20 watt DC 12 volt light bulb and in full sun at noon meter was reading that it was only allowing 14 w total to be generated. Pretty cool for the price to use as a learning tool for showing kids householder works but not very useful for anything else that I can think of

As other reviews note, the 'manual' is very hard to figure out, and there are no set up instructions other than connect the pieces together???? I cut the plug wire from the clips, and connected the clips to the battery and the other ends to the controller, based on the + and - terminals of the car battery. The hard part is determining what is the positive vs negative wires from the panel. So I put the panel in the sun (with the plug into the panel). I used a voltmeter and found it read +7 volt and if I switched wires it wa -7 volts. The former was the positive wire setup and I then screwed those wires into the + and - terminals of the controller. You have to push the leftmost button to switch between voltages of the panel, battery and load and I think if you hold the menu button for 7 seconds you can actually program the controller voltage limits, but I left those as the defaults. In summary, it works, but you have to do some work to wire it up right. I don't know about power output, not holding my breath but It should keep minor lights and minor cell phone batteries charged.

Received all parts they advertised. Clean construction, solid hardware, they do provide 2 cords that connect the battery to the panel, but you must provide your own connectors to the load output.

Protective film over panel is flaking , cracked and falling apart. panel stopped charging and even tho it has a warranty Amazon a can't and won't help, tried to contact seller to getting no answer Biggest piece of GARBAGE. DO NOT BUY

Even in full sunlight, this PV does not seem to work with included BMS. So either the PV is way over rated, say just 10W/15W? Definitely too small to make 25w, and/or the BMS does not work?

ok so the thing works when plugged into cig lighter and clipped onto battery but Instructions are not given on how to hook up the monitor and see power output. There is no plug port on the monitor that fits any of the cables. I cant find who makes it so i can look at a video or some other instructions. not too well thought our. Plus it only came with 3 suction cups not 4 like pictured.

The most I can get out of the panel is 4 to 5 Watts in direct sunlight. It is the middle of winter, so there is some loss, but I doubt you can get 25 Watts out of this panel.
