Why is my power bank recharging slowly?

For faster charging, use a PD charger rated at 30W or higher. With a 30W PD charger, the power bank takes about 4 hours to fully recharge.

Is it normal for the power bank to get slightly warm during use?

Yes, a small temperature rise is normal. The product meets the safety standards for a maximum temperature rise of 118°F (48℃).

How can I estimate the number of charges for my device?

To estimate charges, use this formula: (Power Bank Capacity × 0.7) ÷ Device Battery Capacity. For example, an iPhone 15 Pro with 3,274mAh can receive about 4.27 charges from a 20,000mAh power bank (20,000mAh × 0.7) ÷ 3,274mAh.

Why does the power bank sometimes not charge when multiple devices are connected?

This power bank supports multi-port output up to 15W total (5V/3A). When the built-in cable is used with either the USB-A or USB-C port, the output voltage is 5V. Make sure your devices support 5V charging.

How is power distributed when using a single port or multiple ports?

With one port, only the USB-C port can deliver up to 45W. The USB-A port can deliver up to 22.5W. With multiple ports in use, all ports share a total 15W (5V/3A).
