美国采购需求：深层组织手持按摩器、肌肉放松按摩器、冲击按摩枪、筋膜枪

I'm reaching out because I've encountered an issue with my mini massage gun. Unfortunately, I've misplaced the charging component, and I'm eager to find a replacement. If you could provide me with information on where to purchase this specific part, it would be greatly appreciated. As I live in Los Angeles, USA, I would prefer local options if available. However, I'm also open to online retailers or other solutions you might suggest. Your guidance in helping me restore my device would mean a lot. Thanks in advance for your assistance with this matter!
