Burn­ing down the house

Mac Format - - APPLE TALK -

Q Is my iPad charger a fire haz­ard? It seems to get quite warm, even when the iPad isn’t con­nected. Denise Bryant A All mains transformers use some power even when there’s noth­ing con­nected, and this power is dis­si­pated as heat. In a mod­ern power sup­ply, this power draw is minis­cule. If yours is no­tice­ably warm, that’s a clue that it’s prob­a­bly a cheaper, coun­ter­feit charger. Be­ing warm isn’t a fire haz­ard by it­self, but the lower build qual­ity could con­ceiv­ably re­sult in a short-cir­cuit and cause a fire.
