ECO-WORTHY 12 Volt 5 Watt Solar Trickle Charger for 12V Batteries Portable Power Solar Panel Battery Charger Maintainer for Car Boat Marine Motorcycles Truck

To be sure, I ran a thorough test. I tested the solar panel with a multimeter that was set to continuity measurement. The multimeter would attempt to power the solar panel if the leads were connected via the positive clip. There was no logical progression! There was continuity when I connected the leads in the opposite direction (positive lead to negative clip). This means that the solar panel has a diode that prevents current from flowing from the positive clip (much like a car battery attempting to charge this device). Then I went to the 12v socket connector. br>br> Inside is an LED and a resistor, which must be cut out/removed. The car battery will be drained if this is left plugged in for the night. The 12v socket connector consumes no electricity after the resistor and LED have been removed. I have yet to put this to the test on a sunny day, so I have no idea how much voltage or current it will produce.

This is great for trickle charging my truck battery, but I've only recently discovered that it can also be used as a USB solar charger.

. You can plug the solar charger into one socket and a car USB adapter into the other(s) if you buy a 12-volt power (cigarette lighter) extension with two or three outputs. There is no need to plug anything into the cigarette lighter. br>br>Power will flow from the solar panel into one socket, powering the USB adapter in the other.

I've bought a variety of solar chargers from different manufacturers (but not this Eco-friendly one). So far, the most deserving model) who actually WARPED from sitting in the sun on the dashboard of a car! However, this charger has performed admirably thus far. It does produce power, but whether it will be sufficient to keep the battery from draining is unknown. I needed to know if it worked right away, so the first thing I did when I got it was use a VOM meter to measure the power coming from the charger (I had to do this because I've received other chargers that were DOA right out of the box). It does, in fact, create power, according to my findings. Of course it makes more power in bright sunlight (about 30% more) and it makes power even in overcast weather as well. br>br>It's a good question to ask why anyone would need this in the first place. The answer is that modern automobiles use battery power even when they are parked. This energy is used to keep the radio's memory and the computer in the car alive. Despite the fact that the power used to keep- The percentage of people who are still alive is extremely low - mA - mA - mA - mA - mA If the car sits idle for a week or longer, this power could be enough to drain the battery. Some people even disconnect the battery of a car that has been parked for an extended period of time, which helps to keep the battery from draining. However, because the computer memory is gone, if you disconnect the battery, the car will need to be driven for a long time for the computer to reset for the "smog test memory" (the best description I have, for certain functions that the computer stores and that are the first thing they look at during a smog check). Long story short, if you have a state smog check coming up soon - Disconnecting the battery is the absolute LAST thing you want to do! Since those functions haven't been reset, it won't pass smog. Regardless, I measured the voltage on the cigarrette lighter socket and came up with nothing. All of the fuses were good after I used the VOM with the dial set to check continuity. Instead of opening a can of worms by attempting to repair it, I simply used the supplied clips to secure the battery. The power cord was then run from the engine compartment to the passenger side door frame, where it was closed. And then I placed the charger on the dashboard, where it took a reading from the alligator clips as shown in the image. br>By the way, the panels are covered in plastic when you receive them; simply remove the plastic for optimal performance; if using a sharp object, be careful not to cut the panels. br>br>Update 9/21/2017: I've been using this solar panel for a few months now, and the battery hasn't died yet, so it's still going strong. I purchased a second unit and set it up in the same manner as the first - I simply routed the cable out of the engine compartment and into the cabin, then shut the door. The alternative is to cut a hole in the firewall to fit the cable through, which I don't want to do; instead, I'd rather change the cable every now and then if necessary. I suppose the only way I'd know if the cable is too worn is to periodically measure the voltage at the clamps; otherwise, it could stop charging without my knowledge.

Using a DC Ammeter multimeter, I measured the current coming from this solar charger to be 0. At 18 volts, the current is 022 amps. In bright sunlight, the voltage is 66 volts, which equals 0 volts. br> 41 Watts. br>Not even close to the 10 Watts claimed by your company. These solar chargers are fakes. br>Anyone purchasing one of these solar chargers should have a DC Ammeter or a multimeter that claims to be able to measure DC Current.

The lighter has a power on Red led, and it didn't work, so I ordered a second one, which arrived without the led on the plug, just an empty hole. I sent four messages to them, and they replied that it was supposed to work and that they would contact me after their week off. When I sent my last message, they said they needed a picture to figure out what was wrong. I'm returning this one with a photo and will replace it with one that works and has a working power on light; without the led light, you can't tell if it's working or not. br>br>The customer shouldn't have to buy a Multi-Tool. To test if it works, use a meter.

br>My brand new car battery is now damaged, and it no longer holds a charge like it did before I bought this product. br>The silicone didn't cure completely, and there are a bunch of craters. br>I'll update as time goes on
I hope this doesn't detract from the quality. br>* charges effectively, despite the fact that it is a cloudy day. This product isn't lasting very long, as evidenced by the burn in the cells. br>In addition, once it's in your hands, the return policy expires, so those are red flags; save your money. br>I also have an Allpowers solar panel, which is of much higher quality.

This was purchased in order to be environmentally friendly. WORTHY 10W solar panel for recharging our teardrop trailer's on-board battery This month, we used the board car battery on a camping trip and were very happy with its performance. It isn't large enough to fully charge a battery, but it is more than adequate for providing a trickle charge to keep the battery charged. When we used it on a daily basis, it kept the battery charged enough to run our interior lights for the entire two-year period. a week-long journey Normally, they are only good for three days. 4 days. That's a win in my book. br>br>This panel is well-made and designed, and it includes adapters for charging the battery via direct post clips or a power outlet. A USB adapter would be a welcome addition, allowing it to be used to charge a phone or other device as well.
