Customer Reviews for VEVOR 30W 12V Solar Panel Battery Charger, Solar Battery Trickle Charger Maintainer with Built-in Smart Controller & 3 Connection Cables, IP67 Waterproof Portable for RV Car Motorcycle Boat Van Camper

Fait le job ! En plein soleil la puissance produite mesurée est supérieure aux 30w créte annoncés

Pour le bateau, plus besoin de charger la batterie avec un fil à l’avance, la batterie est toujours chargée

The 20w and 30w solar panels are perfect for charging my trolling motor and boat motor batteries. They are the perfect size any easily tucked away when not in use.

Seems to work well on my Cart, only use the cart every couple of weeks

The panel easily achieves its rated voltage (15 V DC) under overcast conditions. This is much better performance than several of my other panels.

Works great !!!

Seems to work well. Output affected quite badly by shadow so needs to be in clear view of the sky. If your screen has a tint as is the case here in Florida, this causes a loss of output. In bright sunlight inside the front windshield I could get 0.5 amps. Free standing outside in the sun I easily got 1.3 amps so it will provide the rated output under the right conditions . The plastic suckers are ok but need totally clean glass to stick properly. For it's stated use as a battery maintainer covering a standard drain on my truck of around 80 mA it works well.

Direi molto utile, fa il suo lavoro di mantenimento della carica batteria...unico neo, non è di facile stipaggio, essendo ingombrante. Forse è meglio una delle versioni ripiegabili.

Light and good but pay attention to the 12V auto plug, it has reversed polarity so you need to change it if you want to use it - open it up and solder the red wire to the middle and the black one to the sides.

Good value, work great.
