Safety is our number one concern; the Energizer jump starter has a built-in UL approved battery, most lithium ion jump starters are built with non-approved batteries in order to save on cost. This could leave you stranded with a battery that won’t last or even worse a battery that is not safe to use
The ENJ12K includes an LCD screen that will show you the battery level, so that you can make sure to charge the battery when it’s too low
Unmatched performance, Our jump starters ability to start a vehicle will outperform any other jump starter with the same battery size.
The ENJ12K includes smart cables, these smart cables are critical for the safety of the jump starter and your car battery, the protections include; Reverse charge protection, reverse polarity protection, low voltage protection, over current protection, over temperature protection and short circuit protection!
