Review: Perfect for Jetski use - I purchased this solar panel back in 2024 to replace one that died after not even 2 weeks of use so I decided to give this brand a try. This solar panel has maintained the battery of my outdoor kept jetski without fail after a year and half of use in full Florida sun and rain. I have never once had a battery issue and my jetski has started up every time. I could not recommend this solar panel enough for maintaining the battery of any vehicle.

### ⭐⭐⭐⭐⭐ Perfect for Jetski use
*by J***Z on December 31, 2025*

I purchased this solar panel back in 2024 to replace one that died after not even 2 weeks of use so I decided to give this brand a try. This solar panel has maintained the battery of my outdoor kept jetski without fail after a year and half of use in full Florida sun and rain.

### ⭐⭐⭐⭐⭐ Works great 👍
*by D***D on December 17, 2025*

I use this to charge a battery for a dump trailer, haven't had any issues. Great product

### ⭐⭐⭐⭐⭐ It will probably keep a battery topped off
*by S***. on May 15, 2023*

Seems like a good idea. I think it works well if there isn’t a load on your battery and it just needs topping off. I tried using this in an RV setting. When the battery was fully charged it did well. However, if cell phone chargers dropped the voltage to at or below 9 volts it quit working. It would just flash like it wasn’t getting good sun. However, start up the vehicle and all of sudden without moving it then it said the sun was good and it was working. I tried putting on the dash and inside the vehicle. It warped in about a week. Not sure why, other plastic things on the dash right next to it didn’t have this problem. I tried placing on the roof of the vehicle with the generous cord size. Strangely, it didn’t improve performance. If the battery is fully charged then it on green steady and shows working. But if your battery drops low which is when you need it the most, it quits working and just blinks green. It probably very useful in other applications. ---------- Edit support reached out to me and replaced the unit and helped me understand how to use it. It will keep a battery topped off. It isn't designed to keep up with a 3.2 amp charger. Works as intended.
