Nothing is more annoying than needing to charge your phone on the road and finding out that the battery is dead, and the power bank you were relying on was not enough!
This is why many users ask: How many times does a power bank charge a phone?
The answer depends on several factors, such as the capacity of the power bank, the capacity of your phone's battery, and the actual charging efficiency.
Therefore, it is necessary to know the correct way to calculate the number of times to charge the mobile phone's portable battery, and how to choose the appropriate power bank for your daily needs or while traveling. Therefore, we will explain to you in this article from NewTech - The best smart charger and electronics store in Kuwait - the right way in a simple way! Follow us
How many times does a power bank charge a phone?
The number of times a power bank charges a phone depends on the capacity of the power bank and the capacity of the phone's battery, which is measured in milliampere-hours (mAh). For example, an 8000mAh power bank charges a 4000mAh phone approximately 1.7 times, or about one and a half times fully. The number of times charged is calculated using the following equation:
Number of times the phone can be charged from the power bank = (power bank battery capacity x 0.85) ÷ (phone battery capacity)
Where 0.85 is called the efficiency rate, which takes into account the amount of energy loss and incomplete efficiency during the process of charging the device using the portable battery.
✅ Example:
Let's say a power bank with a capacity of 10,000 mAh , and a mobile phone battery with a capacity of 4,000 mAh.
Number of times charged = (10000 x 0.85) ÷ (4000)
Number of recharges = 8500 ÷ 4000
Number of times charged = 2.13 times, which is approximately two and a third times.
|
📌 Note: To calculate the number of times your phone can be charged with a power bank, neglecting the efficiency rate, you can apply the following law: (Power bank battery capacity) ÷ (Phone battery capacity) Therefore, in the previous example, 10,000 ÷ 4,000 = 2.5, i.e. two and a half times, neglecting the efficiency rate. |
How many times can a 5000mAh power bank charge a phone?
This depends on your phone's battery capacity. For example, a 5000 mAh power bank can fully charge a 4000 mAh phone once, while a 2500 mAh phone can fully charge it about 1.7 times, or one and a half times.
✅ Anker Power Bank 5000 mAh from NewTech Store combines small size with powerful performance, providing 22.5W fast charging for most phones and smartphones, with a built-in USB-C cable.
-
iPhone 15: Charges up to ≈ 79% of the battery.
-
iPhone 15 Pro Max: Charges up to ≈ 56%.
-
Galaxy S23 Ultra: Charges up to ≈ 60%.
How many times can a 20000mAh power bank recharge a phone?
A 20,000mAh portable power bank can charge a phone with a 5,000mAh battery about 3.5 times, based on the following equation: (20,000 x 0.85) ÷ 5,000 = approximately 3.4 times. While if your phone battery has a capacity of 3,300mAh (such as some Galaxy phones and the iPhone 13), a 20,000mAh power bank can fully charge it about 5 times.
How to choose a power bank that suits your needs?!
When choosing a power bank that suits your needs, first make sure its capacity is suitable for your daily use (preferably double the capacity of your mobile phone's battery), in addition to its support for fast charging via a USB-C port, as it is compatible with modern devices. If you need to charge more than one device, choose a multi-port power bank, such as the Anker 40,000mAh Power Bank with four outputs.
Here are the top 4 factors to consider when choosing a portable battery for your devices:
1️⃣ Capacity (mAh)
Choose a portable battery with a capacity that suits your daily use. For example, if your mobile phone battery is 3,000 mAh, a 10,000 mAh power bank will fully charge it about three times. It's best to choose a power bank with a capacity that allows you to charge your phone at least twice before recharging the power bank.
2️⃣ Size and weight
The larger the capacity of the power bank, the larger its size, so for daily use, a portable battery with a capacity of 10000mAh - 6000 is ideal, while for travel and long trips, you need larger capacities with a larger size, such as the Anker portable power bank . 25000mAh NeoTech Power Bank with 165W Fast Charging and Built-in Retractable Cables!
3️⃣ Port type
It's best if your power bank has a USB-C port, as it supports fast charging and bidirectional connectivity (drawing power from the power bank to the device and charging the power bank from the same port), so if your device is new (like the iPhone 15 or new Android devices), make sure the power bank is compatible with it.
4️⃣ Number of exits
If you want to charge multiple devices simultaneously, choose a power bank with multiple ports. The Anker 40,000mAh Portable Battery is the best multi-port power bank, allowing you to charge four devices simultaneously with a massive capacity and up to 30W charging capability.
in conclusion, Knowing how many times a power bank charges your phone helps you choose the right device for your daily or on-the-go needs. All you need is a simple calculation that takes into account the power bank's capacity, charging efficiency, and your phone's battery capacity. With New Tech, you can find a power bank that combines high capacity, compact size, and ultra-fast speed. So choose wisely and stay connected at all times!
