Hello, thank you for your feedback. Our supplier has contacted us based on it and would like to respond below.
"Hello, we are sorry to hear about your experience and especially that the power bank's battery has swollen. Our customers' safety is, of course, our top priority, and for that reason, we will gladly exchange your power bank for a new one. In rare cases, swelling can occur with lithium-ion batteries, which are used in a wide range of electronic devices. This is not a characteristic of this particular model but a general risk associated with this type of battery. However, as soon as any signs of deformation appear on the device, such as slight swelling, it should no longer be used or charged. Thank you for bringing this to our attention. We understand your review, of course, and ask you to contact us by email at
[email protected]. Thank you."
Should you need anything else, please do not hesitate to contact us. Thank you and have a nice day, Ondřej - Alza expert
