【Function】The solar panel and charge controller form a basic off-grid solar kit for charging and maintaining 12V batteries, such as sealed lead-acid, lithium, LiFePO4, Gel, Flooded and AGM batteries. In full sunlight, the 25w solar panel kit can produce 100Wh of electricity. Works even on cloudy days. It is the perfect thing to keep your battery topped off!（Module goes to maintenance when charged）
【Durable Panel】With a low-iron tempered glass surface and corrosion-resistant aluminum frame, the solar panel is protected against weathering and wear. It can withstand wind pressure up to 2400 Pa and snow load up to 5400 Pa. The panel is waterproof, making it ideal for outdoor or winter use. Consists of monocrystalline cells for high conversion efficiency.
【Protect the Battery】The 10A PWM charge controller in this kit allows the expansion by wiring more 12V 25W panels in parallel. It also can prevent the battery from overcharging, over-discharging, over-voltage, short circuit, and reverse current issues. 2 indicators for easy observation of charging and discharging status. With USB 5V/2A output port.
【360°Adjustable Mount】Equipped with solar mounting brackets, the mounting angle can be adjusted for better sunlight reception. Pre-drilled holes on the back of the panel facilitate quick installation and securing. The connection cable is SAE connector, easy to connect and install. The 25w solar battery charger & maintainer kit is perfect for boat，tractor，trailer，truck，RV,generator，shed，electric fence，pump.
【What’s in box】You will get 1pc 25W mono solar panel, 1pc 10A pwm charge controller, 1pc 1.54ft cables with alligator clips and 1pc 1.38ft cables with O-ring terminal.

I measured this under full, high-altitude, southwestern US sun, and got an open voltage of 23.9 volts, with amps of 1.23, which according to the formula of amps x volts = watts comes to 29.4 watts, a little higher even than rated! The solar panel itself is quite excellent, and the cord, some six feet long and covered in a thick, black jacket that looks like it is made to last, makes it even better. I am completely happy with the solar panel itself.
The charge controller is easy to use, and can be set to different battery types, but there is no dedicated LiFePO4 (lithium) battery setting. The main instructions manual included with this says to use the #1 settings, sealed batteries, and the printed instructions on the top of the charge controller itself says to use the #2 setting, for Gel batteries, to charge lithium batteries… I decided to use #2, since that was what the charge controller itself said. Six hours of powerful, full sun & a half hour off of the charger to sit and reach “resting” voltage later, my 7Ah lithium battery had gone from drained to 13.4 volts, or 90% charged. The controller was still charging it, it might have reached full eventually, but that was all the daytime I could spare. In theory the battery should’ve been totally full in about 5.3 hours, based on the capacity of the panel, so I’m going to think the charge controller isn’t as efficient as it could be. Not bad, by any stretch, it very nearly got there, but a more efficient controller would probably have finished completely in that time.
The mounting hardware is the only true weakness of this- it is the point where this goes from “amazing” to “budget” feeling. The brackets are coated in black finish to keep rust away, except for the section on bottom where they overlap- that wasn’t coated, which is tacky. They also feel thin, for the weight of the panel. Although the sections move, they are designed to be used in a straight “+” shape, diagonal angles offer less stability and feel like a bad idea. Because I am planning to mount this onto a wooden deck lower than roof height, I think the mounting hardware is “adequate”, but up on the roof, subject to much more wind and weather, I think this is held too high up on far too thin brackets, and would fear it getting flipped or torn loose in serious storms.
For a complete, starting kit to get into solar charging, I think this is a great value. You could use this for years, and be quite happy. The included charge controller isn’t the most efficient I have ever seen, but it works fine, and the panel itself is the real important thing here, and it is excellent. The mounting hardware is only just adequate, but it works. I’d definitely recommend this, when taken as a whole, it’s an excellent set.

Review is for ECO-WORTHY 25 Watts 12V Solar Panel SAE Connector Kit: Waterproof 25W Solar Panel…. This is a well made, and complete kit. While it is sold as a battery charger, you can use this for lots of things that require 12 volts. There is even a USB outlet on the charge controller for either charging a phone or powering a usb device, low amps. The solar panel outputs 22 to 23v according to my meter testing, and is a good size panel…meaning you have a good chance of getting enough power out of this setup for light loads, like maintaining charge on a battery etc. Nice piece of kit. As always, depending on the sun and angle of the panel when you set it up, the output will vary. Make sure you put the panel in direct sun, but you knew that already. I don’t have any issues recommending this panel and connections. Small enough to be portable to mount easily, or take with you camping or whenever. Large enough panel to get you good output. Free power is always a good thing for my bank account. Comes with an excellently written manual that covers all the basics. Good going ECO-WORTHY!

I don’t know a lot about solar panels, but this one is doing the exact job I got it for which is a trickle charge on 12 volt batteries. I use a car battery for the trolling motor I put on the canoe and this will charge it fully over 2 days. Maybe as we move closer to summer it will work faster, but this is fine. I also like the USB connector, and take it with me to keep a steady current going into the battery on the water. I am going to use it on a shed light as well.

Good panel, great charge controller, versatile and linkable with a fairly sturdy mounting bracket. The system is very light weight. Even in poor light it maintains charging at a low rate and pumps it out in full sun. Tested open circuit current and voltage matches specs. The manual is complete and easy to understand, provides advanced data for integrators. The battery terminal clips are not well suited for flat lugs such as on smaller batteries but in a permanent install you’re going to want to bolt those anyhow. Standard polarized plugs with ground-first. The indicators on the controller are very bright and easily readable while blinded from full sunlight glare. 100% recommended for a small DIY system but remember to fuse it and put it in an appropriate enclosure. The base swivels for easy alignment and it tilts easily but remember to tighten those wing nuts well or the wind will flip it on you.

I got this to charge my LiFePo batteries. I tested it on a 100 Ah Eco-worthy battery. It did a good job of charging this large battery from 78% to 100% over a couple of days. Based on this, It should charge my 20 and 12 Ah batteries fairly quickly from 0% charge left. I thought the panel output was the best part of the kit. The charger was OK and had all needed basic features. Many of these small chargers won’t work with lithium batteries. The connectors and cables are all good. I will probably replace them with other connectors to be compatible with my other equipment. At the current price ($40), this is a great value and I would recommend it.
My star rating scale: 5- Highly recommend 4- Good, maybe check others 3- Look elsewhere first

I’m using this to charge 2 of my 12v batteries and so far it’s working. It looks to be made of good quality and the installation was pretty easy. It’s charging without a hitch so I say we have a winner here. As long as it keeps up its good performance I’d stay happy.
