RP3 Lightning Pak: DT Tested

September 2015 Products Brady L. Kay

There are plenty of other battery chargers on the market today, but we’ve never seen anything quite like this one. The Rp3 Lightning Pak is designed specifically for diesel truck owners and has the power to jump start Power Strokes, Cummins and Duramax engines over and over again.

With 300 amp and 600 peak amp jump starting ability, it truly provides you with commercial-type power, yet because of its small compact size and weighing in at just a pound, you can easily store it behind your seat.

The Rp3 retails for $199.99 and will hold a charge from -4 Fahrenheit to 140 degrees Fahrenheit. After charging the unit for three hours from home, we were impressed that it held its full charge for six months between uses without any problems. Any product that you can put in your truck and forget about until you need it is great in our book and that’s why we feel every diesel truck owner should have one. Worth noting, this manufacturer also offers other types of portable chargers that are worthy of a closer look.
