iPhone charger

In addition to Qi, is this adapter also MFi certified? The point of my reply is that no one here can guarantee, whether or not, this device is "good" for your iPhone. Should something go amiss (not saying that it would), you would have to work with the manufacturer to submit any claims.

What exactly do you mean by "good for iPhone?"
