ECO-WORTHY 25 Watts 12V Off Grid Solar Battery Charger Kit: Waterproof Solar Panel + Adjustable Mount Bracket + SAE Connection Cable +10A Charge Controller for Car RV Marine Boat 12V Battery

✅ Qué me gustó:Este panel solar ECO-WORTHY es una excelente opción para mantener cargadas las baterías de 12V, especialmente en lugares donde el acceso a la corriente es limitado, como en zonas rurales o en Cuba. La eficiencia del panel es muy buena incluso en días nublados, y el material de silicio monocristalino asegura un rendimiento confiable. Es compacto, fácil de instalar y viene con conector SAE que facilita la conexión sin necesidad de adaptadores complicados.⚠️ Qué no me gustó:Sería ideal , los cables podrían ser un poco más largos para mayor comodidad al momento de ubicar el panel.📦 Calidad del empaque o envío:El producto llegó bien protegido, con espuma y cartón reforzado para evitar daños durante el transporte. Todo en buenas condiciones y sin piezas faltantes. El envío fue puntual y sin problemas.🔁 ¿Lo volvería a comprar?Sí, definitivamente. Es una gran inversión para quienes necesitan una fuente de energía alternativa para cargar baterías en lugares donde la electricidad no es confiable o no está disponible. Totalmente recomendado.

Worked great! My car battery was completely drained to the point where my DeWalt charger would not charge it. This charger charged it within a few hours! It was in direct sunlight the entire time. I'm extremely satisfied with this product and highly recommend it.

Finally got to test it. Showing good voltage charging my 12v 10amp battery. But I don't know how it will do for a car battery. Time will tell as I plan to charge a car that's not used very much. Shows 13.57v when charging and 11v when not. I've trying I did notice is that the polarity is reversed. Had to switch the cables around so it's positive. I used the cables supplied by the seller.

This appears to work to charge the Lithium batteries that power my Simrad Fish finder/Chart reader and depth sounder. Its rated output is just about double the wattage of the device the batteries power and it is small enough to just lay it on the flat front seat in my boat ahead of the mast where it gets pretty good sunlight most of the time sailing or all the time rowing. The result is that my 2, 10 Ah 12 V batteries just don't get discharged very much in daylight. When night comes i may have enough power stored to run my chart reader and nav lights at night. i generally don't fish for 24 hours or in winter for that matter.

Excellent product! Easy set up and GREAT customer service!!!

Great product

First of all, I decided to buy this product because I used an electric lunch box in my car for several days and my battery started to need a charge. I didn't want to be disconnecting the car battery to charge it, so I saw some very good reviews about this product. It even comes with a USB charger and I thought it would be very useful.To start with, the product doesn't turn on if the battery isn't connected, which is strange because it had almost 18V input that the solar panel sent to it and so my idea that if one day I didn't have a charger for my cell phone I would just put it on the solar panel without needing a battery died. It does charge through the USB port, but in reality it is powered by the battery and not the panel, which causes a discharge in the battery.I did several tests and they didn't last long because instead of charging my battery, it discharged it. I attached photos of the voltage that went down instead of up.My idea was to keep using my electric lunch box to heat my lunch and leave the panel charging all day so that when I finished work I would find the battery maybe not fully charged but with some charge, but it didn't work, I don't know if the product has some defect but it didn't work for me.It should turn on only with the solar panel on sunny days to be able to charge with the USB port without needing a battery and above all charge the battery because it didn't do that it only consumed voltage from the battery to turn on the module.

Was easy to set up and works great
