Hello, thank you for your feedback, based on which the supplier has contacted us and would like to respond below.
"Hello Filip, we apologise for the complications. Based on the problems you've described with charging interruptions and non-functional ports, it seems you most likely have a faulty unit; this is definitely not the standard behaviour for this product. We would be happy to exchange it for a new one. Please contact us via our customer support at
[email protected]. Please provide the model (of the device being charged, phone model) for the most accurate identification of the issue. We will resolve the whole situation with you to ensure this problem doesn't happen again."
Should you need anything else, please do not hesitate to contact us. Thank you and have a nice day, Ondřej - Alza Expert
