Frequently Asked Questions
Can I bring a power bank on a plane?
Yes — power banks under 100Wh (roughly 27,000mAh at 3.7V) are allowed in carry-on luggage on all airlines without airline approval. Power banks between 100-160Wh require airline approval. Power banks must always be in carry-on bags, never checked luggage. Most popular travel power banks are designed to stay under the 100Wh limit.
How many phone charges does a 20,000mAh power bank provide?
Roughly 4-5 full charges for a modern smartphone (4,000-5,000mAh battery). Energy conversion isn't 100% efficient — expect about 70-80% of the rated capacity to reach your device. A 20,000mAh power bank is typically enough for a 3-4 day trip with moderate phone use.
Can a power bank charge a laptop?
Yes, if it has USB-C Power Delivery (PD) output of 45W or higher. Most modern laptops charge via USB-C PD. A 20,000mAh power bank provides roughly one full charge for ultrabooks (50-60Wh battery). For gaming laptops with larger batteries, you'll need a 25,000mAh+ power bank with 65-100W PD output.
