ECO-WORTHY 10W Solar Panel Battery Charger Portable for Charging 12V Battery or Vehicle Gate Opener,Electrical Fence Chicken Coop Lawn Tractor Boat

Bought this to replace a Mighty Mule gate charger for a commercial client. Worked perfectly for a fraction of the cost. Have not tested the true output, but a year in it's keeping the gate charged.

Use this to change a 12v lithium battery for a automatic chicken coop door. Keeps battery charged.

Update: Ordered another. Using to power my MIghty Mule MM317W. I have two gates, one running off a 5W GTO array. This one seems to be similar quality and puts out twice the watts for 20% of the price. However you have to buy a mast or make one. I bent a 1/2" EMT tube to 45 degrees and used 1/2" EMT 2 hole clamps. For my location, a more shallow angle would be appropriate to compensate for summer angles, but for as much power that is required, it really does not matter when pointing to the South. I drilled thru the clamp and the mast and inserted sheet metal screws to keep it from twisting in the clamps. Has sustained 35mph wind so far. I do not think Eco-Worthy should ship the wires stripped. Too easy to short out. I cut the bare ends off until I was ready to terminate to avoid shorts, and covered the array until it was connected. Shipped in a thin un-padded bag. I hate that. Bad protection especially for glass. Fortunately the manufacturers box was adequate this time and USPS handled it with appropriate care.

I had one of these before, but the one that came with a charge controller. I decided to buy just the panel alone to wire in parallel and use to charge/maintain two 12v sealed batteries of 9 AH and 20 AH respectively. I initially connected them to a Schneider c40 and got 19+v from the PV panels, but the C40 wasn't working so it didn't charge the batteries - I also wanted to test the C40 since I suspected it wasn't working. I connected the panels to another charge controller but it only registers in the 12.5v range for the panels but the days have been somewhat cloudy. I used to use the charge controller that came with the other panel, but the space between slots for panel, batteries and load is very narrow and what with moving it up and down the wires came a bit loose and adjacent ones touched and sparked! Have ordered another charge controller and will connect and see what voltage I get and how quickly it charges the batteries to maximum. Panels seem well made, are fairly light, not sure how water proof the connection box at the back is though. The hole in the box for the wires can hold speaker type wire, doubt it could take anything of a thicker gauge, even the strain relief has a very narrow diameter space and short screws. The back of the panel has 4 holes in the frame for attachment to roof or support. I bought some brackets but not sure if I'll use them yet. I'm currently resting them on an old shoe rack with wheels so that I can easily move it into and out of the house to get sun. Am toying with using the brackets I bought to install on roof but I like the idea of being able to move the panels around so I might not. UPDATE Oct 2018 I mounted them on the edge of the roof and have had them connected to one of the inexpensive blue fronted PWM 20A charge controllers sold on Amazon. I put in a fuse from the wire on the roof to the charge controller as well. I run two DC bulbs from the charge controller, I think I used two 7w ones and used the timer on the controller to turn them on and off after about 6 hours. I also hooked up a mini voltmeter display to the batteries and the 2 panels keep the batteries fully charged with the light load it's running. They've been through some very heavy rain and seem to be holding up okay.

Great quality, and easy to use, a game changer to maintain battery.

I combine this with a Schottky diode and a 20 volt Black and Decker Lithium battery. It powers my small QRP amateur radio in full sun and you can receive, without a battery connected or charge the battery simultaneously. The panel fits well on a bicycle where you may need portable power. If you use any one of the Black and Decker tools, it could well come in handy. Sturdy and good quality, it has survived dropping. rain and direct sun producing 22 volts. peak You can reposition to gain maximum sun. The output of the unit is normal for a panel and you should always purchase a panel twice the power you need. Or go 4 times if you don't get desert sun! The ratings on panels are lab ratings and to learn more about this Google the topic. It's a good panel and does well for me.

This small 10 watt solar panel, powered my muffin fan just perfect

No diode installed. Can't open the junction box to even install a diode. No holes to route the wire through on the side. Do yourself a favor and buy the futuresolar 12v 10w panel instead. It's 25% cheaper and comes with all those things this panel doesn't have.
