Why choose our cup phone holder for car? Upgraded Base is Easier to Rotate When the phone holder was placed in the cup holder, some customers told us that the locking knob was difficult to open. After many trials we changed the base and it is very easy to open the extendable grippers now. At the same time, our base has become more aesthetically pleasing and feels better at the customer's suggestion. Stronger than Traditional Gooseneck The traditional cup holder phone mount uses rubber extender. When it is connected to the mobile phone, the rubber gooseneck can not be supported and shaken due to the weight of the mobile phone, which greatly affects the use and the adjustment of the rubber gooseneck is difficult. So the new version of the phone holder for car perfectly solves these problems. Rotate the button to adjust the angle arbitrarily. The gooseneck is strong enough not to cause any shaking. Provide you with security at your convenience. Easy to Install--Only Takes Three Steps 1. Install the 4t-notch on the back of the holder, then pull up to fasten. When you hear the sound, it means connect successfully. 2. Put the locking knob into the goose-neck and cnnect the holder with the 360° ball head. 3. Swivel the locking knob to fasten the holder with the base. Reserved Charging Interface The open bottom will not affect the charging of the device when you driving, and you will experience the joy of constant power.
