Business trip: When business people are on a business trip, a power bank can ensure that their phones, laptops, and other devices have sufficient battery power to avoid affecting work due to low battery. For example, when on a plane, train, or going out for business, they can use a power bank to charge their devices at any time.
Mobile office: For personnel who often need to work in a mobile state, such as salespeople, field workers, etc., power banks can ensure that their electronic devices are continuously charged during outdoor work, improving work efficiency.
