This is an excellent product I tested it on full exposure to sun at 19.8 V that is no trickle power for goodness sake...!! The feature of a Charging or active solar panel LED is great..... The Cells will react even to household lightning...!!! Sorry did not test the voltage on that. This charger will be used in connection with an power invertor 12V to 120 V ( other seller) and a Car battery Jumper unit.... When connected in proper sequence this will be a life savior in the likes of storms and emergency's ( I added a non electric easy to make Solar Oven look how easy on the internet) also i added to this some Led Lights and a 12 V Road Oven also. Survival at its finest..... and I'm sending it to Puerto Rico and the Caribbean nations.... I bought two because they have a Car so One charges the car and the other the Jumper unit.... that doubles the emergency power output.....! Best of luck to all and thank you to the Seller for making it available such good efficient and affordable product.Read full review

I relied on this item to maintain the battery in my second car. First I checked the cigarette lighter by charging my cell phone with it, and it was fine. Plugged this in, kept it against a sunny window. On Christmas Eve I needed to use the car to go to church, but the battery was totally dead! Charged it with a plug-in charger but could not trust it. I am now plugging it in to keep it charged, but am not sure whether the battery is OK or damaged by freezing. This won't only lose you the price of the charger, but the battery as well!! Avoid!

Purchased to tend battery of a motorcycle parked at an apartment. No electrical outlets close for a standard tender. This provides enough recharge to hold for a few days without riding. Great product, excellent price and compact design makes it easy to leave connected without drawing unwanted attention to it.

Right out of the box, plugged the cigarette lighter attachment in, (absolutely fool-proof), throws voltage even on overcast days, or under artificial lighting. Works through tinted glass, too. Y'know like through your closed sunroof. Beats the hell out of constantly putting the trickle charger on my car. I'm gonna get another one for my other vehicle. IT WORKS!

Own a 2001 car with after market parasitic electronics that were pulling battery down when air traveling. So park in econo outside. Before battery maybe dead depending on time away. Now come back to a fully charged battery. Recommended if you leave a vehicle just sitting. Be sure to follow instructions. Wish had a USB attachment to charge other devices.
