How can I tell if the Hotspot Lungo or Quadro is fully charged? – Fatboy

This is how you can tell with the Hotspot Lungo / Quadro 2.0 (with on/off button on the back of the Fatboy label) that it is fully charged:

Make sure the Hotspot is on, by pressing the on/off button on the back of the Fatboy label. All lights will now flash. Briefly press the front button once. This will switch on the Hotspot. When you now press the same button on the front of the Fatboy label for at least 2 seconds, you will see 1, 2, 3 or 4 lights.

1 light = 25%
2 lights = 50%
3 lights = 75%
4 lights = 100%

This is how you can tell with the Hotspot Lungo / Quadro 1.0 (without an on/off button on the back of the Fatboy label) that it is fully charged:

When all 4 red LED lights in the Fatboy label (directly above 'boy') are on continuously.

For example, if the last light is still flashing, the battery is still charging.
