20000mAh

20000mAh refers to the capacity of the power bank's battery. It indicates how much energy it can store, meaning it can typically charge a standard smartphone 4-6 times, or fully charge a tablet 1-2 times, depending on the device's battery size.

Absolutely. A 20000mAh power bank is excellent for travel, especially in Sri Lanka where you might not always have access to power outlets. It provides ample power to keep your essential devices charged throughout your journey, from remote areas to bustling cities.

Most airlines permit power banks up to 27000mAh (or 100Wh) in carry-on luggage. A 20000mAh power bank usually falls well within this limit, making it safe for air travel, but always confirm with your specific airline's regulations before flying.

The charging time varies depending on the input power (charger output) and the power bank's input capabilities. With a standard 2A charger, it can take 10-14 hours. Using a fast charger (e.g., 18W PD/QC) can reduce this significantly, often to 6-8 hours.
