Solar Car Battery Trickle Charger, 12V 3.3W Solar Battery Charger Car, Waterproof Portable Amorphous Solar Panel For Automotive, Motorcycle, Boat, Atv,Marine, RV, Trailer, Powersports, Snowmobile, etc

Really pleased with this charger,we use it to keep a lesuire battery topped up on electric livestock fencing. Easy to install.absolute 5 Star.

As described

Lower score because the delivery was very late. I purchased this charger because the 12volt battery on my hybrid car failed to start the car after a few days without use. I found it simple to instal by fitting the solar panel to the front windscreen, passing the leads under the bonnet and clamping to the battery terminal. This is 7.5w larger than the previous 3.3w purchase. Time will tell

I bought the unit last year and had no issues until 5 days before the warranty expiry date, the trickling indicator stopped working. I mailed the support team with the fault support by photos, they responded promptly and without any delays they offered my a free replacement (newer model)I am very impressed with the support team, their prompt response and the speed they mailed the replacement.

I have two cars I intended to use this charger on. The first is an older Citroen Picasso where I installed it on the rear parcel shelf connected to a rear 'always on' cigar lighter socket. This seems to work OK and I have had no trouble. Have left the car for several days, come back and battery seems strong on starting.Now the 'But'. I connected to my daughters Mazda 2 at the one and only cigar lighter socket. I was surprised the charging / connected green light came on as I know some other devices do not work from that socket, but the lighter itself works for what it was intended. Anyway I left the car for several days in strong day time sunlight. Green light was on during these times. However when I came to start the car after two or three days the battery was completely drained!I was going to buy another of these chargers for her car, but not now of course. I have no real idea why one car would be fine and the other not. I thought the electronics would prevent the charger being a drain on the battery while there was no sunlight to charge the battery but seems not. I could test by having the charger attached direct to the battery terminal posts, but in all truthfulness I am not that interested just yet.

Use this solar panel for couple of days and no charge in the battery. The SOC (State of charge) dropped in that period. Check the output which was 67mA on a 35C day, well below the spec of 180mA.Returned for refund

There is really nothing I dislike about this product, it seems robust and does exactly the job I purchased it to do! I parked my jet ski beside the caravan and used the suckers provided to secure it to the outside of the window. Job done, up and running in a few minutes!

Good size solar panel that even in low light delivers just the right amount of power to keep the battery of my motor home permanently topped up.It is very simple to connect and disconnect, so no messing about undoing things, and It has an indicator light letting you know when it’s charging. So far very pleaseD with it.
