Review on 🔋 YONHAN 5 Amp 6V/12V Car Battery Charger Maintainer - Trickle Charger for Car, Boat, Motorcycle, Lawn Mower, Marine Sealed Lead Acid Battery and More by Larry Gaines

The thing definitely burned after the first use. The heart crackles, then the smell of burning and the fan stops working. Now the screen flickers and I don't dare use it without setting it on fire. I would not recommend this unit as it does NOT have surge protection despite what it says on the box (assuming it did after I connected the cables correctly and followed the instructions). This thing was cheap and I should have known better as the performance matched the price.
