If your pump isn’t charging, make sure you are using a standard USB wall plug (5V, between 1A and 3A). The pump has a safety feature that prevents it from charging if you use a high-powered “fast charger” or laptop block (anything over 15W). 

If you are already using a standard plug and it still won’t charge, your USB-C cable or battery might be acting up. Reach out to the Customer Service hotline at 6541 1700 and we’ll get it sorted for you!
