F.A.Q.

F.A.Q

When I press the power button on my power bank, nothing happens. Is the battery dead?


No, it just needs to be recharged for 3-4 hours. If the problem persists, please contact us at customerservice@promate.net for assistance and a customer service representative will reply to your inquiry in a timely fashion.

How long should it take to fully charge my portable charger?


Typically, it will take up three to four hours to fully charge a Promate portable power bank after its initial charge. Smaller power bank should take less time, and larger portable chargers or external batteries may take slightly longer. For models with USB or micro USB input port, the output current from USB wall charger or PC USB port will inference charging time too.
