The power bank’s capacity Much like with the capacity of telephone batteries, the power bank’s capacity is expressed in milliampere hours (mAh). Therefore, if your battery has 3000 mAh, then a 10000 mAh capacity power bank should easily charge your phone 3 times, right? As you might have figured out, the matter is much more complicated than this.
So, a good 5,000 mAH wireless power bank such as Anker 621 MagGo will charge iPhone 15 with its 3200 mAH battery nearly one time fully in wireless mode and Samsung S24/S23, only about 80% as these have 4,000 mAH batteries. Here are some tips to maximize the power capacity of your power banks. PowerBank Guide is reader-supported.
The ideal mAh for your power bank depends on the phone battery capacity. The larger the phone battery capacity, the larger the battery of a power bank should be. A 15000-20000mAh power bank should be fine. But, that’s an easy answer. We have explained how much mAh your power bank needs for different devices. Let’s dive in.
In practice, your phone will get less out of your power bank than 20,000mAh. In general, your power bank can transfer around two-thirds (66%) of its own battery power to your smartphone, and there are two main reasons for this. Reason 1: Power banks output at 3.7 volts, while due to USB technical standards, smartphone batteries charge at 5 volts.
That said, in practice, your 20,000mAh power bank won’t even provide a total smartphone battery charge of 14,800mAh, because there is one more factor that reduces its real total output. Reason 2: Inefficiency in the charging process also means that 20,000mAh of power bank charge equals noticeably less than 20,000mAh of smartphone battery charge.
For example, if your power bank has a capacity of 20,000mAh, multiplying this by 3.7 will reveal that it has total energy — as measured in mWh — of 74,000mWh. However, it will need to output at 5 volts to charge a smartphone, so dividing 74,000mWh by 5 — to convert back into mAh — will equal a smartphone battery charge of 14,800mAh.
So, a good 5,000 mAH wireless power bank such as Anker 621 MagGo will charge iPhone 15 with its 3200 mAH battery nearly one time fully in wireless mode and Samsung S24/S23, only about 80% as these have 4,000 mAH …
