How to Use Your Power Bank for the First Time?

How to Use a Power Bank? a Full Usage Guideline

It’s fairly simple to use a power bank for the first time. Sometimes all you need to do to get started is take the item out of the box. But generally, you should charge the power bank first before using it.

Let’s go over some fundamental things you need to know before using a new power bank for the first time.

Read the User Manual First

Read the user manual completely before using your new power bank. Although the use of a power bank is simple and straightforward, this doesn’t mean you should ignore the manufacturer’s recommendations.

The user manuals are tailored specifically to the gadget you’re using. You should adhere to the manufacturer’s instructions even if some of the information you may find in the manual does not overlap with what you are about to read here.

Do Power Banks Come Pre-charged?

Yes, the majority of power banks are pre-charged. Most of the time, though, it won’t be a full charge, only about 75% or less. It’s almost never the case when purchasing a new power bank that it comes fully charged.

Of course, it’s also possible for you to get a power bank with no power at all. This is especially true for gadgets that were sold after spending a long time on the shelf. After a while power banks, just like any other battery, will start losing power until they completely deplete their charge.

How to Charge Your Portable Charger for the First Time?

As a best practice, you should fully charge the power bank before using it for the first time, even if it has some charge out of the box. Almost all power banks come with a charging cable that can be used with other power sources, like the USB port on a laptop, or with a wall outlet.

Please note that the majority of power banks do not come with a wall charger. Many people are not aware of this when they place the order and then get disappointed when they see that the package does not contain one. Furthermore, you should be aware that not all chargers have the same power capacity.

Some of them provide more power and can therefore charge a power bank more quickly, while others are slower and can prolong the amount of time it takes for your device to charge by several hours.

You can simply charge the power bank using the USB port on your laptop if you don’t already have one when you get it. Just keep in mind that because USB ports from laptops have very low current outputs in this situation, charging the power bank will take a very long time.

Recharging your power bank too much can be dangerous. In the long run, this could harm the battery. This is why after plugging it in, you should check the charge indicators from time to time. You needn’t worry, though, because some power banks have overcharging protection. To find out if your portable charger has this feature or not, consult the user manual.

Here is how to charge power banks of different brands:

Using the Power Bank for the Very First Time

You can tell your power bank is fully charged when all four of its lights start to blink. Unplug it immediately after that, of course. Afterward, you can use the power bank to recharge your phone.

Most devices have at least one USB port, but some also have multiple outlets for electrical discharge. You can get various output values such as 1A, 2A, 2.5A, etc. Your devices will charge more quickly as the amps increase. So if you want a fast charge use the port with the highest output.

Different fast-charging technologies are also available in some power banks. These are great for delivering really fast charging times, but you should be aware that the device you’re trying to charge should also be compatible with the type of fast charge your power bank can provide. In such a case, regular charging will take place rather than fast charging.

Laptops can be charged using power banks as well. But in this case, the power output should be big enough in order to meet the laptop’s power needs. Most manufacturers advise utilizing the USB cable (and wall charger) that originally came with your power bank.

However, cables and wall chargers have extremely broad compatibilities, so you should be able to use essentially any type of cable or charger, provided they are well-built. Using inexpensive and/or subpar chargers and cables will result in slow charging times and may even harm your power bank.

Why Do Some Power Banks Take Longer to Charge?

Larger batteries have a greater capacity to store energy, so some power banks require more time to charge. For example, a high-capacity power bank with 20,000 mAh can take up to 40 hours to charge fully. Smaller 4,000 mAh power banks might charge in just a few hours.
