Description

Why do I need a solar trickle charger? Three reasons to own a Sunway Solar Battery Trickle Charger: Operation: For optimal power, ensure the panel is directly facing the sunlight. Clean the Solar Battery Charger MONTHLY, or more frequently to maintain peak efficiency. Check the battery is 12V and larger than 50Ah. If the battery capacity is 50Ah or greater, the charger will not overcharge the battery or cause any damage. If the battery capacity is smaller than 50Ah,a suitable charge controller will be required. Or,please don't continuous charging more than three days. The solar charger is a basic of trickle charger and it is best for slowly charging and maintaining battery charge.Please note that the charger is designed to top-up battery charge as a result of natural drainage. It is not intended to recharge a battery that has fully discharged. The charger should not be submerged in water. The solar charger panel can be mounted to the windshield or mounted using the mounting holes and place the charger in the desired location in direct sunlight. Plug the solar charger into your vehicle's 12-volt lighter socket. In some makes of vehicle, the cigarette lighter may not operate when the ignition is turned off. The charger can be connected to the battery using the crocodile clips provided. Note:Ensure the red cable is connected to the positive (+) and the black cable is connected to the negative (-).

My husband purchased this for our older cars and truck recently. He doesn't use his truck every day, so he keeps it on the dashboard. It works really well, as our driveway is in a location which gets a bit of sun every day. He will move it from vehicle to vehicle, as he needs it and it has not failed to charge yet! ... show more

I got about 3.7W max power with the cell sitting flat on the driveway in Oct in Dallas around 2pm. I did not tilt it to get the optimum angle. Initially the power was about 1W higher but after 30-60 min in the sun the efficiency drops. The panel is rated for 8W if I can get 1/3 to 1/2 of that, I'm happy. I also put it in my van on the dash (again not angled toward the sun). The power dropped again (glass is blocking some of the light, see curves). I guess it could overcharge my battery (lead acid) since my parasitic drain is about 70mA and the cell voltage drops to 15.3V at that current (orange curve), but I doubt it since my new van sometimes will charge at 15.5V for 30-60min, then down to 14.4V for most for the time and sometimes as low as 12-13V. Unlike my older cars where lead acid charging was always around 14.4V. When the cell was on the driveway (blue curve) the cell resistance was about 12ohms in the 100mA to 200mA range if that helps. ... show more

    • Not recommended, poor product and customer service
Size: 8W
These have to be in exactly the right position to work, which means you have to have a meter to check and move it with the sun. I had a 4watt, and it worked flawlessly. I returned two of these, and bought another 4w. However, I was only credited for one, even though two were in the return box. Buy at your own risk, and return with even more risk. ... show more

    • Semi large flaw in the product
Size: 8W
Pros: +purchased the 8 watt panel and it had decent output. It was able to charge my battery on my spare car and keep it topped off +Plenty of cable for my use even when the battery isn't IN my car to be charged. I was able to place the panel on my carport roof and it still could reach my battery on the ground with cable to spare. Cons: -this is a big one. After less than a month in the sun the plastic housing popped open. I don't think it's waterproof at this point. Upon inspection it popped open because the plastic housing has warped and curved preventing it from being able to stay together. If it can't handle being in the sun then I think a redesign is in order. I can't exactly keep my panel out of the sun to prolong the lifespan of the materials. -the connector fills with water when it rains. The panel was on my daily driver and the connector between the panel and the clips filled with water. I shook it out and everything still works but I can see this becoming an issue after a while. All things considered I'm gonna have to say this isn't worth the money. If it can't handle being in the sun then it's of no real use to anyone. What good is a solar panel that can't handle sunlight? ... show more
