How To Use A Power Bank For The First Time

How to Use A Power Bank for the First Time

Using your power bank for the first time should be a simple process, but there are a few things you should keep in mind when taking it out of the box and getting it ready to use.

First things first, you should always charge it up fully before using it.

Power banks don’t come with a setup procedure and they should be ready for you to start using them right away.

You do not have to worry about discharging or recharging the device before using it and as long as you’ve charged it up first, you should be good to go.

This article is going to go through our top recommendations of things you should be aware of when using your power bank for the first time.

The User Manual

As with any electrical item, a power bank is going to come with a user manual. You should always read and make use of this, despite how easy setting up a power bank should be.

It will tell you about charging indicators and manufacturers’ recommendations of how to use them.

Manuals come straight from the manufacturer and target the specific device that you have bought and therefore you should always follow their guidelines.

A lot of manufacturers recommend you charge the device fully before use.

Pre-Charged Power Banks

Most power banks come pre-charged already but in a lot of cases, this won’t be a full charge and will only be around 75%. You will rarely buy a new power bank that is completely charged as soon as you take it out of the box.

On the other hand, you could end up with a power bank which is empty of charge.

This is common when the device has been on a shelf for a long time before being sold as after so long, batteries in power banks will lose their charge slowly until they are completely depleted.

To assess how much charge your power bank has, you will need to refer to the LED light indicators. When you turn on the power bank, you will need to check how many of these are blinking.

Most power banks have 4 LED light indicators that tell you how much charge the device has. Each light usually stands for around 25% of power and so if 2 out 4 of these lights are blinking, it’s telling you that the power bank is around half charged.

Some portable chargers also come with LCDs and this shows exactly how much charge is left. These types of portable chargers and power banks are more accurate and give you a much clearer indication of how much charge your power bank has left.

First Charge

Portable chargers should be fully charged the first time you use them, even if when you take it out of the box it appears to have enough charge to last you.

Most power banks come with their own charging cable and you can plug this into your wall socket before your first use.

The majority of power banks however do not come with a wall charger and will only provide you with the cable. This means you will need to own a charger when you first buy the power bank.

However, if you don’t own one or need to use the one you own to charge another device, you can charge it via the USB port on your computer.

This will take much longer as it will have a low current output and so it’s important to bear this in mind if you are on a time limit.

Not all chargers are the same in terms of how much power they can supply.

Some chargers supply more power and can charge a power bank faster than others, whereas other chargers are much less powerful and can take up to several hours to fully charge a device.


Although you should charge your power bank when you first take it out of the box, you must not overcharge it either. This can damage your battery in the long run and can decrease how long your battery lasts.

After plugging it in, you should double-check the charge indicators frequently to avoid overcharging. Some power banks also come with overcharging protection and this means you don’t have to worry about it too much.

To find out if your power bank comes with this protection, check your user manual.

Using The Power Bank For The First Time

If the four lights are lit on your power bank, this means your device is fully charged. Next, you simply need to unplug it and you can use your power bank to start charging up your phone.

There is always at least one USB port but most devices come with more than one outlet for discharging electricity. However, it’s usually the case that not all outport ports on your power bank deliver the same amount of power and you can get different output values of different Amps.

The higher these Amps are, the faster your devices will charge and so if you want a faster charge, use the port with the highest output.

Some power banks also come with fast charging technologies and these are great for delivering fast charging times.

However, you should be aware that the device you are trying to charge should be compatible with the type of fast charge your power bank can provide. Fast charging will not work otherwise and the device will only get a normal charge.

You can use power banks to charge up your laptop but the power output must be big enough and hold enough power to meet the laptop’s power needs.

Most manufacturers advise utilizing the USB cable and the wall charger that originally came with the power bank. Cables and wall chargers have a wide range of compatibility and so you should be able to use any cable or charger.

However, make sure this cable and charger are high quality and not cheap or poorly made. Cheap or poorly made cables and chargers will result in slower charging times and might cause damage to your power bank.

A power bank with an empty battery will take a lot longer to fully charge. Even the quickest charging power banks will take around 2-3 hours and slower ones might take up to 8 or 10 hours.

If charging time is something that will affect how you use your power bank, make sure you do your research before purchasing a new one.

How Long Does A Power Bank Keep Its Charge?

How Long Does A Power Bank Keep Its Charge

How long your power bank keeps its charge will depend on the type of battery and its build quality. You can, however, expect a high-quality power bank to hold its full charge for around 3-6 months without any battery loss. Power banks of lower quality will only be able to hold their charge for around 4-6 weeks.

To prevent battery loss of your power bank, try to keep the battery power on at least 50% and when it reaches below this, the battery cells are more likely to get damaged.

If your device uses lithium-ion batteries, partial tops-ups can prolong its lifespan and help the device retain its charge for a longer period.

To extend battery life, and the lifespan of the device, you should also keep your power bank in a ventilated area between 30-90 degrees. Storing your device in a humid area can impact lifespan as moisture can seep into the batteries and this can cause rust and damage the condition of the battery.

Maintenance Tips

After you have used your power bank for the first time, there are still a few things you need to consider if you want to extend its lifespan. These include:

  • Do not let the battery reach less than 20%. When you see that it has hit 20%, recharge it as soon as possible.
  • Do not expose it to high temperatures.
  • Do not cover the power bank whilst charging.

It is also good practice to recharge it every 2-3 months, even if you are not using it as regularly as this. This can prevent the battery from becoming faulty.

Final Thoughts

We hope by reading this article you are prepared for when you next buy a new power bank.

We know that a power bank is a great long-term investment for those that are always on the go and need to keep their phone charged.

With the few considerations in this article, you can extend its lifespan and get the most out of your power bank, whilst also keeping the battery healthy and allowing you to keep all your portable devices charged on long trips.
