### ⭐ 







  
  
    NOT a 30 amp relay(s)
  

*by A***R on Reviewed in the United States on October 25, 2017*

Not as advertised. NOT a 30 amp relay. Installed this relay for a custom cooling fan system in my car pulling 28 amps and the relay and wires attached to connector both melted.

### ⭐ 







  
  
    Cheap. Can't handle even half of the 80 Amps
  

*by J***S on Reviewed in the United States on July 14, 2020*

Tested with an inverter, 335 watts at 12 volts. Less than 30 amps. and the voltage would drop so far the inverter would shutdown due to the under voltage protection.Replaced the relay with another brand (from the LED Store) and had no issues.

### ⭐⭐⭐⭐⭐
