Function of Intermediary Charging Devices: An Explanation
Pass-Through Charging Power Banks Offer Efficient, Convenient Charging Solutions
Power banks with pass-through charging technology have a substantial market potential, characterized by a current market size of $12.88 billion and a Compound Annual Growth Rate (CAGR) of 11.89%. The reason for this popularity lies in their ability to allow multiple devices to charge simultaneously while the power bank itself is charging.
The primary component of these devices is lithium-ion or lithium-polymer batteries, which store high voltage per unit mass and volume, making them highly portable. With sizes designed to easily fit in a handbag or backpack, they offer users a compact portable power solution.
Pass-through charging is a technology that enables a power bank to charge another device while simultaneously recharging itself. This feature is particularly useful for those who require charging multiple devices efficiently and conveniently, particularly during busy periods, travel, or outdoor activities.
In essence, a series of power regulating circuits are built into the pass-through device, which allows power to travel from the wall socket to the power bank, then to the device being charged. This setup ensures the connected device charges at regular speed, while the power bank charges at an average or slower speed. The question of charging directly from a wall outlet is raised because the outlet can only accommodate one adapter, whereas a pass-through charging device can accommodate multiple devices through USB cables.
Power banks range from 2000 milliamp-hours (mAh) to 15000 mAh. The higher the mAh, the greater the power and the number of recharges for devices such as smartphones, tablets, and other USB-chargeable devices. For instance, a 5000 mAh battery will offer one charge for an iPhone 7, while a 10000 mAh battery could charge the same phone three times, and a 15000 mAh battery could charge it five times.
When charging a single device, 5 watts (1 amp) or 12 watts (2.4 amp) are sufficient. However, when charging multiple devices, 24 watts of energy or more is necessary for optimal charging. Charging several devices requires a suitable input cable, usually a micro USB connected to a wall charger that charges the power bank, and two output cables to charge other devices. The power bank will flash small dots as it charges, with all dots lit up indicating the device is fully charged, and one dot flashing indicating the need for recharging.
By taking advantage of pass-through charging, users benefit from improved convenience and time management. Best practices for using these power banks include using quality wall chargers, monitoring charging status, balancing device load, and keeping cables and ports clean. These practices ensure longevity and reliable performance of both the power bank and connected devices.
- Given the market potential of pass-through charging power banks, users find them especially useful for charging multiple devices such as smartphones and gadgets efficiently during busy periods, travel, or outdoor activities.
- The compact design of power banks, which range from 2000 to 15000 milliamp-hours, makes them ideal for storing high voltage per unit mass and volume, charging various USB-chargeable devices like smartphones, tablets, and other gadgets.
