The Voltmi Magnetic Charging Cable is a 3A Fast Charging, three in one charging cable. Where normal chargers are just compatible with one kind of device, the Voltmi Magnetic Charging Cable can charge Micro, Type-C, and Lightning charging devices. The magnet is so strong that it can strongly hold the phone and you need not worry about the phone dropping even while driving or while traveling. The light glowing in the charging cable while charging is for night indication. And last but definitely not least, it’s not at all easy to find a charger which has a 1-year replacement warranty.
