Frequently asked questions
Can I take this power bank on a plane?
Power banks under 100Wh (roughly 27,000mAh) are allowed in carry-on luggage on most airlines, but never in checked baggage. Always check your airline's rules before flying.
How many phone charges will I get?
Expect about 60–70% of the rated capacity to reach your phone due to normal conversion losses. As a guide, 10,000mAh gives around two full charges for most phones.
How long does shipping take?
Orders are processed within 1–3 business days. Estimated delivery is then 3–5 business days from U.S.-based warehouses and 10–15 business days for internationally sourced items.
How much is shipping for this item?
