HALO Wireless Charger is inspired by the concept of floating balloons. The charger stays flat without the need for external force. To prop up the phone while it is charging, press the position of the ring as indicated. This will prop the charging plate at an angle to form a space. The inner ring charging plate is then automatically raised due to the torsion of the axial spring.
The position of the axle ensures that the contact area between charger and mobile phone is always sufficient to maintain continuous charging regardless of the angle. A light at the bottom of HALO Wireless Charger indicates when the phone is charged.
