What are Power Banks?
Power banks, also called portable chargers, are compact battery packs that keep your electronic devices charged while on the go. Capacity is measured in milliampere-hours (mAh): 5,000mAh gives a partial top-up, 10,000mAh delivers a full smartphone charge, and 20,000mAh+ suits multi-device use or extended trips. Modern power banks support fast charging via USB-C Power Delivery (PD), with some models also offering wireless charging via MagSafe or Qi. Ideal for travel, commuting, festivals, and camping.
