Kindly note that our power banks contain lithium batteries, which fall into the category of dangerous goods. Unfortunately, due to reinforced international transportation guidelines with regards to dangerous goods, it is therefore not possible for our Swiss headquarters to replace a faulty power bank. As an alternative, we offer you the selection of another product from our extensive SKROSS® range to the same value as the power bank*. In the event of having a faulty power bank, we therefore kindly ask you to fill our damage form. Thank you very much for your understanding.
