Being able to plug into the OBDII port is why I bought this. Makes it a lot easier than trying to run wires to battery. Honda Odyssey cigarette lighter plugs are switched, so you can't use that option. I see the charging light on this come on even when the sky is overcast, and it is still charging. I won't know for sure if it will keep my battery good for weeks, but last time I let my car sit for 2 weeks, the battery was dead. So I'm hoping this will be better than nothing.

Measured output with a very strong mid-day sun at 249 ma. I had drained my motorcycle battery down to 12.2 volts. Tried 2 different Fluke DMMs (87 & 88). Both meters showed 248 - 249 ma. I like the handlebar clamp and ball socket. They appear to be well made. I was pleased to see that the connectors match the battery lead that I had installed years ago for my AC powered "Battery Tender".

Just plug it into the OBD port under the dash and it will maintain the battery. Works like a charm and car fires right up after 6 weeks sitting in winter..

I have mine wired through my car from the dash, when I drive the vehicle I unplug it at the wheel well. I would like to add a cut-off switch later, but this is because my vehicle has a battery sensor built directly onto the negative terminal connector. The suction cups cannot stand high heat, so I often find the panel laying on the dash directly. I'm fine with this, and really only stick it back on the windshield when I am driving. Otherwise, it gets plenty of sun just laying on the dash. It's a good tool, definatly will keep a new or decent battery charged, even on cloudy days.

Bought this on Nov.11th for my RV. It worked good for a short time. Found my batteries almost dead with this product installed properly on Feb.5th. Apparently it only worked for a short 87 days. Not happy. Cannot recommend it.

I plugged this into a lawn mower battery and haven't had a problem since. Should have done this sooner.

Bought this to tend the battery on my pickup which is used sparingly since I work from home now. Could not find a good spot to mount it without having to remove it when I need to drive. Also not sure if abd2 connector was actually charging the battery or not. I bought a plug in tender instead for the truck and use this solar unit to charge my fish finder battery. I plan to see if it can be connected while using the fish finder on my kayak to extend battery life. UPDATE: This worked great to charge my fish finder battery though it does take a couple-three days. I have not tried to use it while on the water yet nor am I sure what would be needed for the wiring to be safe and effective. I have discovered that the suction cups on this are not great. I think they are too stiff. If I put them on the window, they usually fall off in less than one day. I worry that if I put them in a window that is up high, the fall could break it. I would love to be able to put the fish finder battery near a window on the tender and know that it will be ready when I need it, but if it falls, there's no guarantee.
