The Stick is the smallest suction cup wireless power bank available! It sticks firmly on the back of a smart phone yet it’s small enough to keep the camera lenses visible so pictures and videos can be taken. Designed to charge on various phone grips, extenders with suction cups are provided to create an easy application over your grip on the back of your phone. Stick is lightweight and compatible with all wireless charging phones. For non-wireless charging phones, charge directly from the USB port with your phone cable. The Stick will charge up to 200% of your phone’s battery, then simply recharge it.
