ECO-WORTHY 10W Solar Car Battery Charger Maintainer 12V Waterproof Portable Solar Trickle Charger for Car Truck Boat Lawn Mower RV Trailer Tractor ATV Utility Vehicle Battery

this is a great trickle charger for my Nissan Frontier. the OBDII works great. i cant use the plug in adapters because when then truck is turned off those plugs are turned off. Having the OBDII gaves me another way to keep the battery topped off in the cold weather and then the battery cable connectors for the other times of the year when the solar panel can be on the outside of the truck. This is a must have if your vehicle is sitting for days to help keep your battery in tip top shape. it comes with different ways to attach it to your vehicle. and there is also a light on the back of the solar panel that lights up to let you know that its working sending charge to your battery.

Works great at the ranch.

Works good. Keeps the battery charge.

It will not charge a dead battery, it is not intended to. It simply keeps a good battery charged on vehicles that sit without use for a long time. The product itself is great, I bought 3 of them. What happened is, the first 2 I bought were delivered but at 2 different prices 🤔so I called Amazon and was told they can't help me. So I ordered 2 more at a discount for buying 2 and I returned the higher priced 1 still new in the box. Did not seem to me to be the most efficient way to handle it but, that is humans! The 2nd problem was that the delivery person left the package OUTSIDE instead of INSIDE the safety of a closed in screen porch 🙄. I live in a ground floor house with no steps but yet the package was left outside in plain view from the street and in any possible weather. They simply ignored my delivery instructions and all forms of common sense and respect. If I delivered, I would put things inside a porch whenever possible just for common sense and respect! I can't understand this way of thinking, can you 🤔???

I placed it on the dash of my 2015 Town & Country van on May 15th parked in Cape Canavera Returned on 10/11. Van started right up.

This is a great product because of the use of a obd plug into the engine diagnostic plug to provide solar power directly to the battery. No need for separate power from a 12 volt lighter plug to charge the engine battery Had a problem with missing parts and the company provided them in good order would buy from this company again!

Pros Lightweight Easy setup Mms Cons Very slow trickle charge Gets hot very fast in sun

Not a bad little solar charger, been through rain, snow and ice storm and still working fine. Would buy again if it ever stops working.
