Description

Failed car battery, harness coupling, jump-starting or even just switching the AC unit – nasty voltage spikes can occur anywhere, anytime! The built-in gasdischarge tube is an elegant, clever solution. Usually, this gas, secured within a tiny glass tube, does not conduct electricity. However, when a high voltage is applied, the gas becomes ionized, enabling a new low-resistance path for the excess voltage to flow. Excess voltage that otherwise might have fried your devices!
