Be sure to use a low-amp charger to avoid overheating. Most car chargers have 2A ratings, some even have 3A. My SJ4000 is routed directly to my ignition (not cigarette lighter port), using a 1A charger.

AFAIK, a high amp charger should not be a problem. The amp rating is the max it can provide. The actual current (amp) that will drawn from the charger depends on your device.

If you have a 1A device plugged in a 3A charger, that charger will supply only the required current (amp).

Am I right?
