What are the differences in battery life and charging methods between the two models? Do they need to be charged frequently?

- USB-powered model:

Charging method: 5V2A USB port direct plug (requires 5V2A plug or power bank), does not support wireless charging;

-Battery life: Varies depending on the capacity of the power bank. Taking a 10,000 mAh power bank as an example, if used for 15 minutes a day (with all functions including air pressure, heat therapy, and vibration on), it can last for 10 to 12 days.

- Wireless charging model:

Charging method: Supports direct charging via Type-C;

Charging time: Fully charged in approximately 2 hours (the red light module increases energy consumption);

Battery life: Equipped with a 3000 mAh battery, with 15 minutes of full-function use per day, it can last for 8-10 days. When both the red light and heat therapy are turned on simultaneously, the battery life slightly decreases (about 6-8 days).
