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

Light and sturdy for its thickness, it does the job but it needs some light to get to charging voltage. Not so good: 12V plug comes with reversed wiring (the red + should go to the middle, the black - to the sides) so you need to do some soldering work, the voltage passes 15V a bit

Works great at a really good price.

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.

The size is perfect for me. There is full advertised solar output in full sun. The extra accessories were "nice to haves" but I doubt I will use most of them The only real disappointment is the wire gauge used. Sure, it is large enough to carry the current but, it could either be larger or protected with an external cover. As it is, it looks very frail and I expect the wire will be broken after only a few uses.

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.

Work well for slow charging, but suction cup don't seem to work at all.
