3.3 watt-Pro

Working like a charm. Keeps my battery charged

I picked this Solar Charger up during Amazon's Memorial Day sale and so far it works as described. As anyone knows, a project vehicle can take a long time to complete but knowing my battery remains charged and ready to go when I finally fire up my project gives me peace of mind. Having a good battery is now one less thing I have to worry about!

I Don't usually comment ：The 3.3W fine Solar battery Tri flow charger maintainer-12V for automobile item to maintain a 12v battery. I have it attached to my SUV while it's in the storage lot. The attachment system allows you to fix the solar panel with screws or, as in my case, on the vertical surface of my SUV with suction cups. It is easy to remove for travel and keeps the battery fresh while the unit is waiting ! Bought 1 of these for use in 2 vehicles. In use, inside vehicles on dash connected directly to battery terminals with included clips, Can't go to work because of COVID-19 for nearly 2 months 。 Multimeter test results: I'll be testing regularly ! #1 Car battery 12.30V . solar charger 18.10V, LED working #2 Car battery 12.80V-13.00V .full sun solar charger Single one 20.00V-22.00V ，I love this charger. My car starts, like it’s a new battery, each time 。 full sun.charger case has melted, and LED no longer works 。I contacted Amazon.com, and then the manufacturer contacted me for the address very happy and received the new solar panel ! This solar panel is on the market for $12-more. I paid a little more than $34. Half of it is insurance ! "But I recommend that manufacturers use aluminum frames in the future"!

Tapping the sun to trickle charge my riding mower battery makes sense. The storage shed I use does not have electricity so this is a cost saving alternative. Quality device with multiple ways to connect items being charged. This works on my generator as well. Keeping the battery topped off waiting for the next hurricane!

Purchased two of these and was NOT disappointed. I placed them in two of my vehicles that sit outside in the upper northern area of WI, and the weather takes a toll on cars that sit out side. These units stood up to the -30 deg F very well. Prior to using them I’d have to start the cars every two days and let them run to charge the batteries as there location was to far for a trickle charger to be used. These did the job very well. Extremely cold weather sitting for two weeks, I’d have a hard time starting the V8 with any battery left out that long, not with these units, plenty of cranking power as if you just dropped in a new battery full charged and ready to work. Charges on cloudy days as well, just not full power. I am going to purchase a few more for my family to use....good product and rather strongly built.

I'm pretty sure this charger ruined my relatively new car battery. I have a car that is rarely driven, and I really liked the idea of not having to remove the battery to keep it on charge with an AC battery maintainer. This solar charger seemed like the perfect solution, in that it would use the power of the sun (no outlets needed) and mount inside my car (watertight). I installed the charger using the alligator clips direct to the battery, verified it was giving out wattage with a voltmeter prior to install and generally had the car parked in the sun. I even turned the car over every month. I had a new (15 month old) Interstate battery in the car, and simply wanted this charger to keep the battery topped off in good condition. Well today (maybe 3 months since install of solar charger) I tried to turn the car over, no dice. Tried jumping it, no dice. Brought the battery to Valvoline to be tested and they said it only had 87/500 CCA and that the battery was shot. Thankfully the battery is still under warranty but it looks like I'll be getting a proper AC powered battery charger.

i’ve had this for over a month now. I was using it on a car I drive in frequently. I had it plugged into the cigarette lighter which I can confirm does receive power when the vehicle is off. After a week and a half the battery is dead. And that’s with getting good light direct all day long. It may work for some people, and it may work connected to the actual battery, but not in my situation connected to the lighter. I wouldn’t recommend it.

I bought this panel and the Zeallife Solar controller at the same time because of other reviewers problem with charging their vehicles with this solar panel. Just got everything hooked up today on a bright sunny day to my vehicle and was using the 12V DC Plug to go to the battery. I only got a reading through the Zeallife Solar controller for about 1 to 2 seconds. I wiggled the 12V DC plug near the plug and the current reading went on and off. I took the 12v DC Plug apart and found the negative wire was not soldered onto the medal at all. The panel does seem to be working well though. Just wished there was better quality control with the included items to help charge the battery. Just need a replacement for the 12V DC plug and not the whole panel kit. POWOXI just contacted me several day later after I support this problem to their customer support. POWOXI is sending a replacement for the defective 12V DC Plug for the solar panel kit. They do have great customer support and are willing to help. I will be getting another solar panel from them soon for my other vehicle.

Super produit et super qualité Fonctionne très bien C’est léger à transporter à t très utiles Je suis très très content

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.

Buena conpra

Seems to charge well, hopefully put it on my old tractor for a day, next day she fired up pretty good and usually the battery is quite low from sitting

Easy to install, inside or outside your vehicle and you can either clip it onto your battery terminals or in your cigarette lighter (if your vehicle has one). A day after the panel arrived I received an email via Amazon from the manufacturer Thanking for buying their product restating installation instruction and giving hints and tips on getting the best out of the device. Been very useful during the lockdown and an idle car.
