We can kindly confirm that the Quatro Wireless Power Bank only comes with the charging cable included (Type-C to Type-C). A power adapter is not provided with the purchase of the power bank.
You should be able to use any Type-C power adapter as long as it is able to provide at least 18w in order for the power bank to charge at a quick rate. If you plan on using a Type-A power adapter, you may need to use a Type-A to Type-C charging cable or Type-A to Type-C converter to connect to the provided cable.
We hope this information has been able to provide a bit of clarification and guidance.
Please feel free to reach back out to us if you were to have any further inquiries or immediate concerns.
