Troubleshooting
This section addresses common issues you might encounter with your Bubbacare Heated Socks.
Issue 1: Failed to control temperature via APP
- (A) Battery Charge: Check if the batteries are fully charged.
- (B) Battery Connection: Ensure the socks are properly connected to the batteries. Verify if the socks can be switched on/off manually or if the red gear light can be activated.
- (C) Component Isolation: To determine if the issue is with the socks or batteries, try exchanging batteries between socks and reconnecting.
- (D) Bluetooth & Location: Confirm that Bluetooth and location services are enabled on your mobile device.
- (E) Proximity: Ensure only the pair of socks you intend to connect is within a 10-meter range. If multiple pairs are present, connect them one by one.
- (F) APP Operation: Check if the socks are powered on and if there are any incorrect operations within the APP, or if the correct sock button is selected in the APP.
- (G) Rebinding: If connection attempts repeatedly fail, exit the APP, clear the APP and mobile phone cache, then attempt to bind again.
Issue 2: Strengthen gear (Flash-Heating) only operates for 1 minute then automatically closes
This is a safety feature designed to prevent low-temperature burns. The Flash-Heating mode is intended for rapid initial heating. After 1 minute, it automatically reduces to a lower, sustained heating level to maintain a comfortable temperature and conserve battery life.
Issue 3: How long does it take to fully charge the batteries?
With an adapter greater than 5V/2A, a single battery takes approximately 5-6 hours to fully charge. If the adapter is less than 2A, the charging time will be longer, or the current may be insufficient for charging.
Issue 4: How long will the batteries last on a full charge?
Battery duration depends on the selected heating gear. It typically ranges from 3.5 to 11 hours. Under comfortable temperature settings, you can expect 4 to 6 hours of use.
