If your air pump doesn’t appear to charge fully, don’t worry—this is often due to one of the following two situations:

🔍 Possible Causes & Solutions

1. Normal Behavior During Recharge Detection

Even when the battery is fully charged, you might notice the device continues charging for a few more minutes when you plug it back in. This is normal.

Why this happens:
During charging, the system monitors battery voltage. The voltage while charging is slightly higher than when idle. So, even if the battery is already full, plugging the charger in again may trigger a short charging cycle—giving the impression it’s not fully charged.

Solution:
No action needed. You can safely unplug and use the device.

2. Battery Performance Issues

If the device continuously fails to reach a full charge or drains unusually fast, it might be due to a battery issue.

Solution:
Please reach out to our customer support team for a proper diagnosis or a potential replacement.
