The average power bank lasts 1.5-3.5 years or 300-900 charge cycles. However, this number can differ depending on a few things. For example, the quality and battery capacity play a role in how long the power bank will last.

Additionally, the build, brand, and type of battery all play a part in the power bank’s longevity. Finally, how you use the power bank also makes a difference.

Find out how long your charger really lasts

Ideally, your portable charger will last a long time. But it’s not always the case that you can be sure.

The good news is that there are some things you can do to maximize the life of your portable charger.
First, don’t overcharge your phone. This could fry your battery and ruin your charger. Remember that the more often you charge your phone, the sooner it will die out. So try to limit how often you charge it and only charge when necessary.
Second, make sure to use a power bank during short trips instead of charging directly from the wall outlet.

Power banks store enough energy for a few hours of use, so you don’t need to worry about running out of battery before then. This can save you money on electricity bills, as well as extend the life of your portable charger.

Turn off your charger when it’s not in use

A fully charged cell phone battery will lose 2% of its charge per day if left unused. But if you charge your cell phones every two days, you’re actually reducing your battery life by as much as 15% each year.

So get in the habit of charging it every night and turning it off when you’re not using it, or at least putting it in airplane mode. If you always keep your cell phone on and plugged in, your battery life will be severely reduced.

Turn off your phone anytime you’re not using it, or put it in airplane mode. Unplug it at night, and give it a break while you’re at work.

Don’t charge your portable charger at the same time as your phone

You should NEVER charge your phone and your portable charger at the same time. This is for a couple of reasons.

Firstly the portable charger is typically at a higher mAh level than your phone, so it will be charging up your phone much faster.

This puts an unnecessary strain on the phone. If it can’t keep up with the portable chargers speed, then it will force the phone to shut off before full charge. This will allow the portable charger to only charge the phone to a certain point, not letting the phone charge fully.

Secondly, the phone will shut off to prevent over charging. This isn’t always a bad thing, but it can be if your phone is not fully charged.

The phone will still be receiving power, so it will start to heat up and can potentially cause damage to the charging port.

Use a different charging cord whenever possible

The most important thing you can do is to make sure the charging cord you use is not damaging your device. A friend of mine once had a portable charger die on her, and she realized that the cord she was using was causing it!
If you charge your phone with a different cord, you will extend the life of your charger. Not only does this preserve the life of your charger, but it also extends the life of your device by reducing wear and tear on the battery.

Not to mention that using different cords means you can use multiple chargers without having to repeatedly buy new ones.

Reset your portable charger every now and then

To avoid a damaged portable charger, you should reset your portable chargers every now and then. This also ensures that you are using the most efficient way of charging your phone. Resetting your device will create a fresh cycle with no other charge cycles to potentially damage the battery in the long run.
Another thing that can do damage to your battery is using it all day. The more often you charge your device throughout the day, the greater risk of damaging it is.

Leaving your charger plugged in all day may actually cause it to malfunction or even explode due to overheating.

You should use it until its fully charged and then unplug it so that it can cool off before recharging again while saving energy at the same time.

Use a portable battery pack

If you’re going to use a portable charger, don’t charge your phone too often. Portable battery packs can be used in place of a charger. They work just as well and they give you peace of mind that your phone will be charged up when you need it.
A lot of these battery packs are compatible with multiple devices, so it’s convenient to keep one at home, in the office, and even on vacation.

They come in varying sizes and some even have charging indicator lights to let you know when your phone is fully charged.
This ensures that your portable charger lasts longer than if you were only to use one device at a time.

Take frequent charging trips outside

One way to extend the life of your portable charger is to charge it externally. You can charge your portable charger in a car or on the go by connecting it to a power source since it has an external battery pack.
The more often you charge your phone, the sooner it will die. However, there are ways to extend the life of your portable chargers. One way is by charging them externally rather than internally (i.e., charging them with a power cord).

Bottom line

: Portability is not worth the cost
Even if you are a frequent user of your phone, it’s not worth the risk or worry of having a dead battery. If you’re constantly charging your phone then you’ll need to invest in a second portable charger. It will be an unnecessary expense if you only use it once or twice a year.
