Nokia is temporarily halting sales of its Lumia 2520 tablet in several countries due to a risk of electric shock when using the chargers. An issue with the plastic exchangeable plug could cause the plug to come loose and separate on the European and U.K. version of the Lumia's AC-300 charger, which poses a risk of electric shock. Nokia notes that there haven't been any confirmed instances of shocks delivered by a faulty charger, but they're still urging consumers to stop using those chargers until Nokia is able to send a replacement.
In addition to the AC-300 wall charger, the travel charger for the Lumia 2520 that has been sold in Austria, Denmark, Finland, Germany, Russia, Switzerland, U.K. and the United States. Sales of the Lumia 2520 have been suspended in all of these countries except the U.S., though sales of the travel charger have been halted. Nokia states that there haven't been any incidents due to the flaws in the chargers, and that only the AC-300, which works exclusively with the Lumia 2520, and the travel charger, have these issues, and that all other Nokia chargers are working normally.
Customers who own the affected Lumia 2520 charger are encouraged to send Nokia their contact details for further updates on progress of issuing replacement chargers with a reduced risk of shocking you.
