Technical FAQs 4

What is power bank capacity?

Power bank capacity is typically measured in milliamp-hours (mAh), indicating the total electrical charge the battery can store. However, the voltage of your device and the power bank itself play a crucial role in the actual number of charges you’ll get.

What are power bank specifications?

Understanding power bank specifications requires knowing common technical terms and abbreviations: Capacity measurement. 1,000mAh = 1Ah. Higher numbers mean more charges but larger size. Energy measurement important for air travel (100Wh max for carry-on). USB-C fast charging standard up to 240W (PD 3.1). Essential for laptops.

How much Mah should a power bank have?

A good rule of thumb is to assume that a power bank's usable capacity is about 60-70% of its stated mAh. A high-quality model will be closer to the 70% mark, while a cheaper one might be closer to 60%. When you see a 10,000mAh power bank, think of it as having a usable capacity of around 6,000-7,000mAh.

How to choose a power bank?

So you want a power bank with fast, efficient charging technology. Capacity is measured in milliampere hours (mAh). The higher the number the greater the capacity and the more devices you can charge before the power bank’s Lithium-ion battery needs its own charge. Speed is measured in watts (w).
