I have a 1999 MB E320. The fuse keeps blowing out for the cigarette light every time I try to plug a charger into it. The mechanic I brought it to said that the charger has to be plugged in before the key is inserted & the car is started, in order to avoid plowing fuses. Is that correct? It doesn’t make sense that it should work that way! P2 ---

There is a current surge when something is plugged in. The charger (for what?) must be drawing near the maximum (20 to 25 amps) when it’s running. Add a surge, and the additional amperage is too much for the fuse. What is the watt rating of the charger? Divide that number by 12 volts, and you get the amperage draw. ---

First thanks for the quick response. The charger in an LG OEM cell phone charger & does not have a wattage # listed. Can (& would it be safe) to up the fuse amperage if possible?
