- This EC5 12V Cigarette Lighter Socked Adapter works with most 12V portable jump starters with an EC5 port. - What's unique about our adapter is that it features low voltage cut off protection. - What this means is that when the battery on your jump starter is getting low, this will cutoff power flowing to your 12V device. This is necessary since draining a lithium battery to zero charge can ruin the battery. - Low voltage protection is critical to maintain the life and safety of your lithium jump starter.
