On average, a 20000mAh power bank can provide around 6 to 8 charges to a phone with a 3000mAh battery. However, this can vary depending on the power output of the power bank, which is usually measured in milliamperes (mAh). The higher the power output, the faster the power bank can charge the phone, and the more charges it can provide.

In this case, it would be 3000mAh (device capacity) divided by 2200mAh ( power bank capacity) which equals approximately 1.36. Now, multiply this ratio by the efficiency of the power bank. Let’s assume the power bank has an efficiency of 85%. Multiply 1.36 by 0.85, resulting in approximately 1.16.

We’re starting this guide with a few heavy power banks, especially this Excitrus NitroCharge Pro power bank. This charger has a 25,600mAh power bank. Considering that the S22 has a 3,700mAh battery, the S22 Plus has a 4,500mAh battery, and the Galaxy S22 Ultra has a 5,000mAh battery, a 25,600mAh capacity can charge these phones to full power
1. Power Conversion Rate. Generally speaking, no matter how you describe a power bank is capable of recharging iPhone impressively fast, all the quick charges definitely depend on the battery's power conversion rate. Most power banks' built-in batteries meet the standard power conversion rate 80 to 90%.
For instance, a smartphone with a 1000mAh battery cannot last a thousand hours because it uses more than 1mA. These devices have an estimated electrical draw of 500mA. How Long Does A 4000mah Battery Last? This question has two interpretations: 1). Lifespan – 2 Years. Batteries have limited lifespans.
