ECO-WORTHY 10W Solar Car Battery Charger Maintainer 12V Waterproof Portable Solar Trickle Charger for Car Truck Boat Lawn Mower RV Trailer Tractor ATV Utility Vehicle Battery

immediately powered up and kicked out 15-16 volts unloaded, in rainy/cloudy weather no less. Connected it to the battery and the trickle charge was enough to power the car back up to the threshold for the key fob to work again after less than an hour. Battery obviously has issues and we plan to get a new one tomorrow, and plan to keep this solar trickle charger hooked up help offset some minor parasitic drain. I see some reviews expecting this to charge a dead battery....but that's never going to happen with a panel this small, and it clearly tells you that before you buy it. It's only meant to keep a healthy battery topped up, not bring and unhealthy one back from the grave. Most of the neg reviews are just people who didn't read.

Excellent unit. Works like a charm.

I recently purchased the 10W Solar Battery Charger, and I am extremely satisfied with its performance. The charger is suitable for keeping vehicles/boat batteries charged during weeks of disuse, without the need to disconnect the battery or have someone start the vehicle periodically. The indicator light on the back allows me to observe the charging state, and it’s waterproof, making it safe to use outdoors. The 10W monocrystalline solar panel uses trickle charging to charge the battery without causing overcharging, and the built-in blocking diode prevents reverse charging without extra maintenance at night, ensuring protection against damage. The panel works even on cloudy days, making it a reliable source of power. The upgraded PCB and addition function of reverse and overcharge protections ensure that the panel is still working normally, even if it's not possible to test the open-circuit voltage. The charger is easy to install, equipped with an SAE cable that can be plugged into the cigarette lighter port or connected to the battery terminal posts with the alligator clip. The connection can be completed within 3 minutes, making it suitable for use in cars, trucks, boats, lawn mowers, motorcycles, trailers, dump trailers, tractors, RVs, vans, campers, ATVs, utility vehicles, and more. Overall, I highly recommend the 10W Solar Battery Charger to anyone looking for a reliable, easy-to-use, and effective solution to charge their battery and keep their vehicle or boat running smoothly.

It seems working, left for two weeks and came back battery could still started without problem. However, it is hard to tell if it is charging or not. The green LED indicates sun light also charging with no distinguish. Why can't they make green LED blink to indicate charging, solid green to just indicate sun light detected? Also the LED is located in a hard to see place, why don't they put LED facing outside, so that users can see it through windshield.

This works great to trickle charge my generator battery. It seems to die due to lack of operation. However this has kept the battery charged so that I can use my remote start effectively. Great buy!

FIRE DANGER!!!!!!! DO NOT BUY!!!! CAUGHT ON FIRE!!!! I purchased several of these to keep batteries charged on some of our equipment that we dont use often. One of these solar chargers today caught on fire, the wire insulation melted and shorted out and there was a small electrical fire between my battery and fuel tank on our trailer. We caught it in time but this could have been a major catastrophic with 15 gallons of fuel inches away. I am throwing out the ones i have on other trailers and a new one still in the box.

Charges my battery as advertised. Using the battery clamps works great.

I bought this product to charge my truck battery as I have a drain that empties the battery if I park it for a few days. I figured that if I use the solar charger, my truck will get an extra charge to the battery, which will do me good as I drive short distances and the truck is parked most of the day. I used this product religiously, every time I turned off the truck I plugged the charger into the cigarette lighter. I followed the instructions, which said to use the lighter port that illuminated the light on the charger. I started measuring the battery voltage at night after I got home, and again the next morning and I kept a log. Anyway I noticed that this charger made no difference to my battery at all. I used it a different car and had the same result. So it didn't work at all through the cigarette lighter. I hooked the panel directly to the battery one day and measured the voltage and it worked well. It was charging the battery. My advice would be to wire this panel to the batter directly, maybe with a switch to turn it off at night and when the car is running. But, not to bother using it through the cigarette lighter.

Prima bueno services:)

12 Volt 10 Watt Portable Power Solar Panel oplader Backup voor auto werkt goed

I don't drive my car as much as I should and therefore have been using a 240v trickle charger to keep it charged but it isn't convenient rolling out an extension lead. This solar charger has solved that problem and is working very well. The cable runs under the seals on a closed door and under the bonnet with no problem.

Auch gut bei start stop probleme halt Batterie 54 Ah bei 98 %

dopo averlo provato qualche giorno, per tenere in vita la mia vecchia batteria dell'auto (di quelle costose fatte per essere continuamente caricate) ho deciso di prenderne subito un'altro!! In pratica il pannello lo danno per 10 watt, ovvero 700-800 milliampere , il voltaggio a vuoto si aggira sui 19 volt, con il carico arriva sui 14 circa, nel mio caso ho un consumo fisso intorno ai 400-500 milliampere (dovuto anche all'antifurto tracker gps) quindi se ho la batteria in perfetta forma (quasi mai visto che l'auto fa pochi chilometri e sta ferma per 1 settimana) si riesce a non rimanere a piedi....ovvero non si carica ne si scarica...ma ricordiamoci che adesso il sole e' molto forte!! e quindi abbiamo quei 10 watt detti belli pieni. Prendendone due....collegati in parallelo, mi assicuro di avere un 1500Mha in uscita verso la batteria quindi, almeno 1 ampere per la ricarica della stessa, anche nei giorni di meno luminosita ho abbastanza carica di mantenimento e una leggera ricarica. Prodotto promosso al 100% molto ben fatto anche nei collegamenti , e ovviamente Amazon sempre veloce e precisa.
