Leercon Portable Muscle Massage Gun with 8 Massage Heads and USB Rechargeable. Personalized Massage Experience: LEERCON massage gun with 6-speed settings. Choose from gentle vibration for warming up sensitive areas to powerful percussion for deep tissue relief, addressing all your muscle relaxation. Long-Lasting Portable Power: Enjoy several times of cord-free muscle relief on a single charge. The built-in 2000mAh battery lets you take this massager to the gym, office, or on trips without worrying about finding a power outlet. Charging Note: This massage gun is designed to be charged only with a standard 5V charger. If a higher-voltage (e.g., 9V, 12V) or fast charger is used, the internal circuit protection may activate and charging will not proceed. This is a normal protection mechanism, not a product defect. Deep Tissue Relief: Target stubborn muscle tension with percussion therapy. 8 Attachments for Every Muscle: The set includes 8 interchangeable massage heads, each designed for specific muscle groups.
