Shipping Policy
New Zealand Shipping Fee for 1 unit：$6-8;
Estimated shipping for 5 units: $20–$30 USD；Estimated shipping for 10 units: $40–$50 USD.
For orders shipped to India, due to current shipping restrictions, relatively high customs duties may apply. The estimated customs duty is $10–$15 USD per shipment. The good news is that the customs duty is approximately the same whether you order one or two power banks, so we recommend purchasing 2 or more units at a time for better value.
Due to increased customs inspections in Europe, additional import fees may apply to European shipments. Based on the current situation, all European orders will require an additional customs fee of approximately €3–6.
