Charging

Two Watts of solar ain't much power. You gotta know what to do with it. I am using this little panel to power a (2W) five inch muffin fan in my shed. Works just like I thought it would. Sun's out the fan runs. No sun the fan shuts off. Doesn't cool the shed much. But it does move the air around. Total cost was about $20. No outside wiring. And it runs for free. Walmart sold this solar panel for $12. Couldn't resist.

Two Watts ain't much

walmart.com

I have been using this for almost 6 months and it has maintained my car's battery at full strength during that time.  At $14.44, I figure it was less expensive than buying a new $$$ 12-volt automobile battery every year.  Even at the new $22.00 price tag, still a good investment and reliable.

A good investment for my car battery

[This review was collected as part of a promotion.] Walmart is awesome as always!

[This review was collected as part of a promotion.] A bit higher price than it should have been.

I replaced one which was over 10 years old.  Perfect replacement.  If you have a vehicle which is not used frequently, the battery will run down, but with this Coleman solar maintainer it is never a problem.  The battery is always fully charged and ready to go!

Infrequently used car battery problem solver!

Due to the pandemic my vehicles aren't being ran as much and I kept having my vehicles batteries go dead, not anymore all my vehicles are now staying charged. Perfect size to fit on dashboard or has option to use suction cups to affix to window. Works very well, I am extremely pleased.

Great alternative to maintain your vehicle battery

If your 12 volt battery has a battery drain over a few days; this could be a remedy for you. There is a tiny blinking blue light when the solar panel is producing a charge. It works on cloudy days as well as sunny days and has the option of alligator clamps to hook it to the battery or it can be plugged into the cigarette lighter.

Gets the job done

Works fine but it's a no frills device. You need to provide your own monitoring instruments to know if it's doing the job. Unfortunately since I just purchased it I haven't have a chance to test long time sitting. Also most accessory 12 Vdc outlets goes thru the starting key, must make sure that lighter outlet is connected directly to battery.

Works with a but

I have several of these Solar maintainers. They work great for keeping the batteries in my boat and atv ready to go when I don't use them for awhile. I am going to install another one on my travel trailer to maintain the battery from the small drains that they all have while setting. I also noticed that the Coleman brand is a 2 Watt, most others are not that high.

Ready to go

no indicators of it working and it does not keep the battery charged .... slowly trickles down
