I would buy it again.
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.

Good idea
Wife has a 99 5.9 cummins that doesnt get driven all the time. Things batteries keep dying every month so we slapped one of these things on and it helped keep them charged for a bit. I did have to break out an extra cable cause it wasn’t too long but no biggie – gotta plug her in for the cold months anyhow. Easy to install and move around.

Operates as described.
Add 1/2 star for quality, price and delivery, but somewhat under-performance unless in very strong sunlight.

Little tricky to know if it’s on or not…
I like the concept! It’s just no way to tell if it’s on and working the first time I plugged it to the car’s obd connector since it was barely light outside. I tried flashing a light to it but no charging light came on either??? I’ll update any results hopefully I didn’t get a defective one.

Great customer service and product!
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!

Keeps my truck battery charged!
This little solar panel works wonders on my old pickup that I don’t drive much. It came with a plug that goes right into the OBD2 outlet and keeps my battery from draining. I just lay the panel on the dash and plug it in. Very satisfied with the item.
