Advance Safety to Your Booster and Car Battery Security always comes firstly into consideration while we're choosing battery clamps, the inferior ones could result in damage to both your booster and car battery, and even to your safety if in improper operational situation. Etable intelligent battery clamps offer a total protection to ensure the safety of usage, and an automatic recovery in the fault state of the clamps protects your jump starter and car battery. A Little Change, A Great Convenience for You You might clearly know that you have to cut off all connections if fault indication (LED lights and built-in buzzer indicator) occurs due to anti-access battery polarity, which is very annoying and time-wasting. Instead of disconnecting the clamps from your vehicle battery and your booster and waiting for 30 seconds, the only thing you need to do is to remove the clamps from the jump starter and reconnect its positive and negative polarities when you apply Etable intelligent battery clamps. Plugging Order is Not a Matter Anymore As you may be aware that sometimes you are just confused a lot about the sequence of plugging; however, you don't have to worry about it by using Etable's intelligent battery clamps. The intelligent system supports and therefore it doesn't matter for you to plug the clamps to your booster firstly or to connect the positive and the negative polarities to your car battery in the beginning.
