What does the flashing of all 4 LEDs on the B10000 mean?

Q: What does the flashing of all 4 LEDs on the B10000 mean?

According to the official manual of the Intenso B10000 , the simultaneous flashing of the 4 LEDs is not a behavior documented in the specifications for normal operation . Here is what the manual specifies about the LED indicator: All 4 LEDs lit continuously indicate a charge of 76-100% . This is the normal state when the battery is fully or almost fully charged. The flashing of the last LED (the 4th LED if you had 4 lit before) signals that the external battery is almost empty while you are charging an external device. Recharge the battery immediately. If you observe the simultaneous flashing of all 4 LEDs, this may indicate : A charging process of the battery itself — When you recharge the B10000 via the USB-C port, the LEDs indicate the progress of the charge. During this process, unusual LED behavior may occur. A malfunction of the protection circuits — The battery has protections against overcharging, total discharge, overvoltage, and short circuits. If all LEDs are flashing, this could signal an anomaly in one of these circuits. Tip : Try completely disconnecting the battery for 10 seconds, then recharge it with the provided cable and a standard USB adapter (5V, 2.4A max). If the problem persists, contact Intenso technical support at support@intenso.de or at +49 (0) 4441 – 999 111 .
