Running out of battery is a major inconvenience, especially if you don’t have access to a wall outlet to charge your phone. Powerbanks, please! Without an outlet, a power bank can keep your phone charged, allowing you to never miss a selfie or a call from your mother.
It’s time to get charged up to learn everything there is to know about power banks, including their function, types, and why you need one!
What is a Power Bank’s Purpose?
The use of power banks to power cell phones, tablets, speakers, and even laptop computers! If you can charge anything by plugging it into a wall, you can probably charge it using a power bank.
When Did the First Power Bank Come Out?
A Chinese business called Pisen invented the first portable power bank in 2001. The initial design consisted of two AA batteries connected by a circuit! It had its public premiere at the Consumer Electronics Show in Las Vegas.
The first powerbank was cumbersome and had a limited battery life. Today’s designs are significantly more complex and smaller, with far longer battery life. Most contemporary power banks are small enough to fit in the palm of your hand and can charge your smartphone multiple times before dying.
What Does mAh Actually Mean?
mAh stands for milliampere hour. It is a unit of measurement for electric power, particularly batteries. A battery with a greater mAh has more power and lasts longer.
The mAh indicates how much charge the battery can hold and how long it can power another item before needing to be recharged.
How can I determine the capacity of my power bank?
You would divide the 10,000 mAh of your powerbank by the mAh of the device you want to charge. If you’re not sure or can’t find the battery, a short online search will reveal the mAh of your gadget. An iPhone XS, for example, has a 2,658 mAh battery.
According to the equation, charging your iPhone XS for 3 hours and 7 minutes will deplete your 10,000 mAh power bank’s battery life.
Which Power Bank is the Best?
The optimal powerbank will have a bigger mAh capacity than the gadget you’re charging. The bigger the battery on your phone or other electronic gadget is, the more electricity your power bank will need to charge it.
If your electronic device’s battery is 2,000 mAh, for example, you’ll need a power bank of at least 2,000 mAh or more. You’ll be able to charge your gadget for at least one full charge without having to recharge it.
