“What’s the green light indicate after all the blue ones are lit up?”

1-1 of 1 Answer

• Some of our power banks support trickle charging. If you press the power button twice constantly, the indicator will turn green, which means the power bank turns into trickle mode. Then you can use the item to charge the devices which need trickle current, such as Bluetooth headphones. Just this model doesn't support trickle charging. It shouldn't show a green light. This item comes with a hassle-free 18-month warranty. Please feel free to contact us via [email protected]. We're more than happy to assist you further.
