Hi Team, 

If there is a quick, small spark when they plug the unit in, at the connection on the device, or a quick small spark at the mains connection when they plug the AC adapter in then this is no cause for concern. 

If the sparking continues after plugged in then they should immediately unplug and we would need to service. 

Most laptop computers will do this, as they use similar, high current chargers as we do. There are two causes depending on which plug goes in first, but unless you are talking to an electrical engineer, simply explaining that there is initially a very large current draw when first plugged in, lasting less than a second. Once the adapter and unit are plugged in that current draw reduces to normal, and no additional sparks should be seen. It is very normal as well for the adapter to get quite warm while charging. Short of getting to hot to hold, that is also not a concern. 

Please make sure to investigate as much as possible in this type of cases. 

Regards,
