I bought 2 of these, one for home, one for work. I tried both and encountered the same problem. The charger worked when first plugged in, but stopped charging after a few minutes. They are said to be MFi-certified and have a fast charging function. Checking my phone after 30 minutes and finding it has 2% charge is unacceptable. Also, the only part that says "MFi Certified" is on a barcode sticker affixed to the outside of the box. I return them and buy either Apple chargers or an Apple certified MFi brand.
