will this panel charge a 12 v. car battery

It can trickle charge the battery if it is angled at the sun without any shade. If you intend to deplete the battery you will need more than a 10 watt panel.

It will maintain a battery with a reasonable amount of direct sunlight on the panel

I use mine to trickle charge a big marine battery than runs my automatic driveway gate. Works all winter long

I don't know if this answers your question but the car charger is a 12v charger.

No your charging system will not harm it as long as it is 12 volts and in good working order.

I don't see why not, I have mine hooked up to my batteries so basically I'm using it like a multi-meter.as long as you're not going over the voltage rated for the meter.use caution as most 12v panels exceed 20v open curcuit.

This works as a battery maintainer, not a battery charger. If you want to charge a battery for a power inverter, you need a much larger solar panel. To put this in perspective, this provides around 2.5 watts maximum. The 12v power plug in most cars is capable of more than 100 watts. I have mine attached to a deep cycle RV battery and it will barely maintain the charge, even with the battery disconnected fro the trailer.

Car chargers are designed for 12 volt systems. This should work fine provided the connecting port for the device matches.

Yes. You connect the battery with the charge controller. This is only for 12Volt battery. If you have 24volts, you will need to replace the charge controller with a MPPT one.

Yes, this battery can accept from 12V to 19V DC power for charging. If you have a solar panel with output voltage 12V ~ 19V, you can use it to recharge this battery. The charge port connector size is 5.5x2.1mm. Best regards.

If your 10 watt solar panel will keep your 12 v. battery charged it should work.

Hello Jennifer, Yes, the Guardian 12V Charge Controller will charge any 12V battery. The Guardian can handle a maximum of 90 Watts input. You can use 3 - 4 Boulder 30 panels with the Guardian to charge your 12v battery. Thank you for your interest - I hope we can help you - Denis, PrepareDirect

set up properly, this would work to charge any 12v battery. you may want to work in a solar charge controller if you are worried about overvoltage protection and other features that can add safety. one thing this will probably not do is bring a dead car battery back to life, if that is the nature of your question. BTW... I have successfully done this with this very panel, and a small 12v 7ah battery. A few good hours of sun will give you a good recharge trickle, but its not much power (smaller panel). You may want to consider a deep cycle battery if you intend to use the battery over and over after recharges. Hope this helps. set up properly, this would work to charge any 12v battery. you may want to work in a solar charge controller if you are worried about overvoltage protection and other features that can add safety. one thing this will probably not do is bring a dead car battery back to life, if that is the nature of your question.

this is a small solar panel, it will keep a 12volt car battery charged, I use mine for a 12 volt winch for a boat hoist. you could get a inverter to connect to the battery for 110volt lights.

I have the 2KW and YES it will charge the 12 volt battery and otput 110 volts

You would have to cut the 12 volt car plug off and make sure you connect the polarity correctly in your panel. This will void the warranty.

Yes, if you have a standard car 12v cigarrette -&gt; 5v usb adapter & the included usb cable it will charge the battery just like a wall adapter would

Sorry, I can't see how that could possibly work as this device charges AA and AAA sized batteries from a standard 125VAC outlet/power source. I have no idea what would happen if you connected and 12VDC battery or solar panel to it, but I'd bet that it wouldn't be good. A better idea would be to find a small 12VDC to 125VAC inverter to connect your solar panel to, and plug this charger into the inverter. Yet another idea, see if Duracell, Energizer, or any aftermarket manufacturer actually make an automotive/12VDC charger. Good luck.

Nope, dual 6 volt battery setup= 12 volts. I think I saw this panel available in 12 volts though. I have purchased six of these and love them so I hope you can make it work!
