Customer Reviews for VEVOR 20W 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

Ho acquistato il pannello per tenere sempre in carica la batteria dell’elettrificato per il recinto degli animali. Sembra che funzioni alla grande ottimo acquisto.

so far these chargers are working great. easy to use and comes with many options to connect to your battery

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.

It does a good job of keeping the battery on my dump trailer topped off. Id buy it again

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.

Great product at a fantastic price.

Itsellä tämä setti lataa kahta isoa akkua VSR välityksellä. Riittää pitämään akut täynnä veneessä vaikka pilssi välillä käykin.

Unsure about how long this polymer sheets PV panel will last, metal frame and glass surely will last longer but will be heavier etc. The back white box is unnecessarily big and thick , wish it were thinner at least since it sticks out. What you need to know is there is a blocking diode so when not generating , it is not discharging the battery either, some cheap ones (including supposedly battery charging PV, dont have diode so it discharges battery and PV gets hot too, no good). the sealed extension is very convenient as well as several option from clamps to just terminal etc is very handy , the 12V cigarette lighter socket, you need to use with caution since it is low current but higher than 12V so small electronics will get fried if you connect to it. overall I am happy with purchase since light and small . It is similar physical size to a 10W monocrystaline PV I had before, but this charges must faster so I believe it is close to 20W, it charges so fast that I needed to connect a charge controller, since it was overcharging the battery, little current but high that 12.8V no good for battery and electronics, even though car's charging system can get up to 14V if needed but no good for battery's health. Remember to get a charge controller for small battery or planning to leave the PV connected all the time

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

This was easy to install! Lightweight & works well!
