What Is Power Bank?

cheapest power bank

A power bank is an electronic gadget that stores electrical energy in it. Power bank works as a power source that you can carry anywhere. They are light in weight and slim in size so carrying a power bank is an easy task.

Whenever your devices like mobile phones, laptops are out of battery then the power bank helps you to charge these devices if you are in hurry and don’t have enough time to sit and charge.

How To Select a Power Bank?

Mobile phones, laptops, smartwatches, wireless headphones are essential gadgets for many people, they can’t imagine their day without these gadgets. When these gadgets are out of battery, you are in hurry and don’t have time to sit and chare them then power bank becomes an important thing at that time.

Aside from the usual reading reviews and checking manufacturer reputations just as you would do with mobile phones, wireless headphones, or any other gadget the most obvious place to start is with the battery’s capacity.

it’s typically expressed in milliamp(mAh) hours which despite the name is actually not a unit of time. So, rather a unit that describes the amount of electrical energy a device can hold. For example, you can think of a device whose battery has fewer milliamp hours like an iPhone has a cup of water and a power bank has more milliamp-hours as a bucket of water.

So, a battery pack with a high milliamp-hour rating can hold enough energy that it can power up your device multiple times or power up devices like tablets with a higher battery capacity themselves.

So, consumer-grade battery banks start around 5,000 mAh and go all the way up to over 30000 mAh and more. These devices at the higher end of that range are capable of charging your average smartphone 4 to 5 times or even more.

best power bank to buy

But if you’ve had a few of them you might have noticed that the best power banks with the same mAh rating can vary quite a lot in terms of performance.

So, one more thing keep in mind that not all batteries are discharged at the same rate all the time.

If you’re charging devices that draw a lot of current for high-end tablets this is especially true. This lowers the effective capacity to below what it would be if you were just charging low-current electronics.

Apart from battery life than just battery size, there are features to consider.

We compared different battery banks that advertised everything from built-in LED flashlights to shock and water resistance. Most known brands were within 15% of each other. The worst one power bank tested was less than one-third as productive as some of the others.

It is a huge factor for folks who want to plug in for 20 minutes while getting ready for that big date and not have to carry their charger around for the rest of the night. Earlier power banks have either one amp or two-amp outputs both of which are running at the standard USB 5 volts.

Many new devices accept two amps of current. Then you need a 2-amp output power bank to charge your device faster. If you need to use a mobile while it’s charging keep in mind though that charger is labeled as 4.8 amp or more.

Some other high numbers are usually referring to total current across all of the port’s which is great if you’re going to be plugging in multiple power-hungry devices at once.

For some people, the regular USB port isn’t enough though there are even some power banks that support fast rapid charging technologies. It can power up your devices even more quickly by increasing from 5 volts up to as high as 20 volts those require both a device and a charger that support them.

Now go forth with this knowledge and find yourself the best power banks that give you all the power to charge the mobile phone you’ve ever wanted.
