### ⭐⭐⭐⭐⭐ Great value

As described

### ⭐⭐⭐⭐ Appears to be functioning as expected.
*by N***I on 18 May 2024*

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
