Updated 2026-07-22 · Power Bank Guide
The OnePlus 11 Pro is a powerful smartphone, but its battery life may not be enough for long business trips. Choosing the right portable charger can be overwhelming, but our expert guide will help you find the best power bank for fast-charging your OnePlus 11 Pro on a business trip.
What Capacity Do I Need for My OnePlus 11 Pro?
To determine the right capacity for your power bank, we need to consider the battery capacity of your OnePlus 11 Pro. According to OnePlus, the battery capacity is 5000mAh. To calculate the required power bank capacity, you can use the following formula: Power bank capacity = Mobile device capacity x Desired number of charges. Let's assume you want to charge your phone at least 2-3 times. Using the formula, we get a power bank capacity of 10000mAh to 15000mAh. However, considering real-world efficiency, it's recommended to choose a power bank with a capacity of 20000mAh or higher.
Is 20000mAh Enough?
Yes, 20000mAh is enough for most smartphones, including the OnePlus 11 Pro. This capacity can charge your phone at least 4-5 times, depending on the real-world efficiency. However, if you need more charges, you can consider a power bank with a capacity of 25000mAh or higher. Keep in mind that higher capacities also mean larger and heavier power banks.
Choosing the Best Power Bank for Travel
When choosing the best power bank for travel, there are several factors to consider. Here's a buying guide to help you make the right decision:
- Capacity: As we discussed earlier, choose a power bank with a capacity of 20000mAh or higher.

Other alternatives, such as Anker or Mophie, also offer high-quality power banks, but INIU's 20000mAh capacity and fast-charging output make it a great pick for the OnePlus 11 Pro.
