This portable phone holder is compatible with all ipads or smart phones and e-readers. Larger devices may be too heavy, please adjust the ipad bracket to a suitable height for stable support.Variously adjustable: Through this ergonomic design, the angle and height of this desktop phone holder can be adjusted to help you find the right angle to expose your full face for video calls/conferences.Ultra stable design: Because the table frame for mobile phones has metal poles and the bottom is equipped with metal plates, the center of gravity is concentrated on the bottom. Compared with all plastic and hollow stents, the stability is three times that of ordinary desktop stents. The fully covered silicone back panel can firmly fix all mobile phones/tablets.Fully foldable and easy to carry: The fully foldable and pocket-sized compact design is a companion for mobile phones/tablets that can be carried around. The ipad stand can be stored when not in use, and does not take up space to make the desktop more tidy.
