Review on 🔌 Monoprice 1.17ft Power Cord Splitter - Black, NEMA 5-15P to 2x NEMA 5-15R, 16AWG, 10A by Lakeem Pickel

I have this along with the NOCO GENM1 4Amp 1 under hood mounted charger, NOCO Genius GCP1 Black 13A 125V AC Port Plug on my F250 diesel truck Used so I can quickly plug in to heat up my coolant and charge both batteries at the same time. The cables don't get hot and the charger definitely does a great job of keeping both batteries charged and running in 4 hours.
