Can the capacity be upgraded without changing the cabinet? How does the mobile charging station achieve flexible expansion from 72 to 216 slots?

October 31, 2025

The power bank vending machine is deployed in public places, allowing users to conveniently rent and return the power bank rental station, solving the problem of insufficient battery power for mobile phones and other devices when they are outside. In international airports and transportation hubs with high passenger traffic, conventional 48-port charging stations have limited capacity and cannot meet the high-frequency charging demand. To achieve effective coverage, multiple devices need to be densely deployed, which increases investors’ costs.

The 72-port combination charging station perfectly solves the high-frequency charging demand in high-traffic venues. The 72-port charging station adopts a main cabinet + sub-cabinet design, which can be flexibly expanded into 120-port, 168-port, and 216-port ultra-large charging stations. The flexibility of the combination charging station helps investors configure precisely according to the actual passenger flow, maximizing business benefits.

1. Why should investors deploy 72–216 port combination power bank stations?

According to The World Factbook market analysis report, the United States, Brazil, and Australia rank among the top countries in the world in terms of the number of airports, with 16,116, 5,297, and 2,257 respectively. The more airports and transportation hubs in the target market, the greater the potential returns for investors. In large airports with massive passenger flow, there is an urgent demand for large charging stations. The combination charging station can meet the instant charging needs of a large number of travelers.

Meeting the rapidly growing market demand: As global users’ dependence on smartphones deepens, high-frequency mobile charging demand continues to rise. In large commercial areas, international airports, and transportation hubs with heavy traffic, combination charging stations, with their flexible expansion advantages, can effectively cope with dense charging demand and help investors seize market opportunities in advance.

Improving operational efficiency and investment return: The 72–216 port large-capacity design adopts a “main cabinet + sub-cabinet” combination structure, which allows flexible expansion according to the site’s needs. It easily handles high-traffic areas such as shopping malls and airports, where users can rent and return power banks without waiting. During peak hours, it maximizes device utilization, improves rental frequency per unit time, and increases investors’ income.

2. What are the features of the 72–216 port combination charging station?

Flexible expansion to meet high-frequency charging demand: The 72-port charging station adopts a main cabinet + sub-cabinet design, supporting flexible expansion. It can be gradually upgraded to 120-port, 168-port, and 216-port ultra-large charging stations to meet the charging needs of high-traffic venues. Investors can first deploy a 72-port charging station to test market response. If rental demand is high and supply is insufficient, sub-cabinets can be quickly added. The combination charging station allows investors to reduce initial investment, respond rapidly to market needs, and seize opportunities for market growth.

Globally compatible and precisely adaptable: The combination phone charger station can be equipped with optional POS modules such as Nayax, PAX, SumUp, Stripe, and MyPOS, allowing users in different countries and regions to complete rentals quickly through familiar payment methods.

Deep scenario service with multiple competitive advantages: The flexible expansion feature of the 72–216 port combination charging station supports deployment from standard configurations to ultra-large stations, precisely adapting to different areas and passenger flow scales. The station offers highly customized advertising screens (touch or non-touch) and cabinet accessories, enabling flexible functional configurations and helping investors build localized market competitiveness.

Intelligent remote operation and efficient management: The cell phone charging station technology platform provides investors with a full-cycle solution from deployment to operation. Investors can monitor all equipment status in real time through the management platform and perform remote diagnostics and control. The system uses intelligent alerts and rapid response to achieve automated maintenance, enabling large-scale operations with low cost and high efficiency.

3. Why should investors choose the 72–216 port combination charging station?

Flexible adaptation to market demand: The rental rate in transportation hubs, large shopping centers, and international airports continues to increase. Investors do not need to replace or repurchase equipment — they only need to add sub-cabinets to accurately match dynamic market demand. The 72-port charging station can be flexibly expanded to 120, 168, or even 216 ports. Investors can deploy sites step-by-step and expand cabinets as needed.

Precise investment and maximum return: Conventional fixed-port charging stations cannot accurately match the rental needs of high-traffic venues such as international airports. The elastic scalability of the combination charging station allows it to respond precisely to high-frequency, dense-usage scenarios, avoiding revenue loss due to insufficient equipment availability.

According to ACI’s World Airport Traffic Forecast (2024–2053), the total number of global air passengers is expected to reach 9.9 billion in 2025 and grow to 17.7 billion by 2043. In the face of the continuously increasing global travel and charging demand, the combination charging station allows investors to build a scalable infrastructure for the long term, ensuring that the shared charging business keeps pace with market demand and continues to capture growth dividends.

Conclusion

In high-traffic venues such as international airports and transportation hubs, the intensity of smartphone usage continues to increase. Conventional power bank rentals with limited ports can no longer meet the concentrated high-frequency charging demand. The 72-port combination phone charging station, through the addition of sub-cabinets, can be flexibly expanded into 120, 168, or 216-port ultra-large charging stations, providing efficient charging services for a large number of users.

Investors can quickly increase capacity based on actual rental data, respond swiftly to market changes, and capture high-value mobile phone charging station locations. This enables investors to establish brand barriers in key scenarios and secure a competitive advantage in the shared charging industry.
