5 Product Comparison

Is it normal for the power bank to recharge slowly?

The 20,000mAh power bank typically recharges in 5 hours and 12 minutes. We recommend using an original 20W or higher PD charger for optimal charging speed.

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

Yes, it is normal. The product meets safety standards with 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 (calculated as (20,000mAh × 0.7) ÷ 3,274mAh).

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

This power bank supports multi-port output with a maximum of 5V/3A, 15W. When using the built-in cable with either the USB-A or USB-C port, the output voltage is 5V. Please confirm that your devices support 5V charging.
