About Renogy 12V 40A DC to DC On-Board Battery Charger
Overall Feedback:
72% positive
84% were impressed with the fast charging speed
The product charges the battery at optimal voltage and current limit, preventing overheating and overloading of the alternator on my vehicle.
64% found it compatible with various devices, but 36% didn't
I explained that the device loads the alternator and increases voltage to charge the battery while driving.
I had to spend an hour trying to understand the table in the manual, indicating that the documentation could have been better.
69% found it easy to use, but 31% found it difficult
The battery charger's performance is unacceptable with today's technology as it falls far short of the manual's representation of up to 90% capability.
66% praised the built-in safety features, but 34% experienced issues
I thought I was safe with a voltage sensing relay on my trailer charge wire, but it doesn't prevent backfeeding.
