Watching your phone or tablet steadily run out of power when you're nowhere near an outlet is stressful. But there's an easy solution: a portable battery or power bank. These are available in many sizes and capacities, and can include lots of handy features like fast charging and multiple ports.
To calculate the approximate number of charges, you must first know the capacity of both the power bank and the battery in your phone. For example, if you have a 10,000mAh power bank and your phone's battery capacity is 2,500mAh, you can anticipate the power bank to last roughly four full charges before it has to be refilled.
Think of it as a backup power source in your pocket or bag, making sure your devices stay alive when you need them most. Most power banks come with input and output ports—like USB-A, USB-C, or Lightning ports—so you can charge them up and then use them to charge your stuff. Some even do wireless charging, so you can skip the cables altogether!
Power banks are designed to be portable. From ultra-slim models that slip into your pocket to larger capacity units that fit in a backpack, there’s a size to suit every need. Their compact design means you can carry backup power wherever you go without adding significant weight or bulk.
The number of times a power bank can charge your phone is determined by various factors, including the power bank's capacity and the battery capacity of your phone. To calculate the approximate number of charges, you must first know the capacity of both the power bank and the battery in your phone.
If portability is your priority and you just need it for everyday use, a 10000mAh power bank should suffice. But if you’re going on a trip or have multiple devices, the 20000mAh – or, even a 50,000mAh – option is the way to go because it will allow your to charge your iPhone and MacBook (and anything else you might have) numerous times.
