13 best power bank maintenance tips you can use today

We have all been in a situation where our mobile devices are low in power and we are not at home to charge them up. Not to mention that maybe you’re waiting for some important call or an email. Right there, power banks come in handy.

But, there’s a catch.

Believe it or not, there are people that, no matter how large is capacity of their  power banks they will drain them to the bottom, standing in the middle of nowhere completely without battery power.

Doesn’t have to be that way.

This is why I created power bank maintenance tips guide, to help anyone who don’t want to lose their power bank charge again, especially not on some important occasions.

It turns out that most of the people are not aware of when and how they charge and use their power banks. They are not organized and use them for granted.


I know that you are impatient to read my 13 best power bank maintenance tips you can use today, and to see how to increase power bank life. So let’s get started with the first one:

1. Avoid exposure to extreme temperatures and humidity

Two of the biggest enemies of a power banks are heat and humidity.

If you expose your power bank either to extreme heat or extreme humidity it will damage your device in certain ways.

Heat will gradually decrease your power bank ability to hold its charge and eventually will go flat. In the flip side, humidity will trap water inside your power bank and may cause short circuit.

This will damage electronic built inside your portable charger. And also will affect it to lose their charge much faster.

For example:

To prevent it from extreme heat do not put your power bank on heating element such is radiator in the winter time, especially when charging it.

Power banks will get warm when charging, and if you add extra heat from a radiator it will cause damage to your device.

Also do not bring your power bank to a sauna. There is an example of an extreme humidity.

Vapor from sauna will get trapped inside your power bank and will cause damage.

2. Use you power bank in the right weather and temperature

When you’re using your power bank you are most likely not at your home.

You’re probably somewhere without wall outlet or in transport or even outside.

If you’re outside you will need to protect your power bank from different kinds of weather.

If it’s raining don’t pull out your power bank, i will become wet. It’s best to keep your power bank inside you pocket or inside your backpack.

You should plan this well, consider to buy one of those protective cases for your power bank to protect from getting it wet and moist.

Also, outside can be sunny too. If it’s sunny and it’s to hot don’t leave your power bank on direct sunlight.

Instead put it somewhere in the shades.

Exposing your power bank to a direct sunlight will extremely warm up your portable charger which is not good in any case.

Protecting you device from high temperature is essential for a good long lasting power bank.

3. Avoid getting power bank in contact with water

Sooner or later your power bank will be on the same table with a glass of water or any other kind of liquid.

If you’re not careful you can splash water from the glass directly on your power bank, which is not good.

Like any other electronic device, power bank will get damaged if water get inside.

So, next time you want to put your power bank on the table watch out for liquids.

Or use protective case which is water resistant to avoid your device getting wet.

In the other side you can consider buying a water resistant power bank. In that case you can be certain that if you splash water on your device, it will not get damaged.

Keep in mind that waterproof and dustproof power banks are more expensive than normal ones.

But if you careful you can get an ordinary power bank and all will be fine.

4. Keep you power bank from impact – Avoid dropping it

Even though we take care about our power banks we can still drop it on the floor by accident.

If power bank hit hard on the floor and on inconvenient angle it will get damaged.

Maybe you’ve slip your power bank once or twice and you’ve have lucky not getting damaged it, but if you keep doing so, it will eventually lead to broken device.

Avoid hits, impacts and drops at any cost.

There’s actually a way to protect your power bank even if you dropping it here and there.

Like cell phones, power banks have silicone-rubber protective case too.

But I guess they made such a cases only for known brands power banks.

So in either ways, quick google search of your brand name and model will tell you whether you can buy one or not.

Or even you can buy power bank that have silicone-rubber protective casing already built on top of the power bank.

But, bare in mind, whether you have regular or with protective casing, avoid dropping it, and it will prolong a power bank lifespan.

5. Use your power bank regularly

It is very important to use your power bank on a daily basis whenever it’s possible.

This will improve battery of a power bank to be healthy and to hold charge better over time.

However, if you let your power bank sitting for too long and not using it, it will negatively affect power bank life.

It will affect it in such a way that your portable charger will not be able to fully charge and it will not hold charge as much as before, when it was new.

If you don’t need to use your power bank for some time it is best to do a charge and discharge cycle once a month.

This will keep your power bank at best shape and it will maintain best performance once you start using it again.

6. Do not charge your devices with a power bank while power bank is charging

Doing so on a regular basis you will damage your power bank very fast.

While you charging your power bank it gets hot, because of the electrons flow throughout the power bank.

When your power bank is charging, electrons flow from cathode (positive part) to the anode (negative part).

This flow makes battery to get hot. When you use power bank to charge a cellphone for example, electrons flow in opposite direction, from anode, throughout the load, and to the cathode.

This make heat also.


Imagine bi-directional flow of an electrons at the same time.

This will cause more unnecessary heat that will damage your power bank over time.

So, power bank in this state must work twice as hard, which will cause damage of internal electronic circuitry and also will negatively affect battery performance overall, and will cause battery of a power bank to hold less charge.

This are very important power bank charging tips.

7. Use original power bank charger to avoid damage

There’s a lot of replacement chargers this days.

If your original charger fails, do not, under any circumstances just buy any power bank charger replacement.

Buy only the original. Bad power bank charger replacements are cheaper, and because of that they are poorly design and they have bad quality overall, and will perform just like that.

It will not provide enough voltage  to your power bank and will damage it over a short period of time.

Cheap chargers have very few components built inside of them.

They don’t even have a protection from sudden electric shocks to smooth out required voltage that your power bank need.

In the other side, original chargers are specifically made for your type of power bank and  it will be your best choice when it comes to replacement of a chargers.

This is also true for a mobile phone and tablet chargers. Use only original once and nothing else.

So, using only original chargers are the best tips to maintain power bank for a long time.

8. Always make sure to fully charge the power bank

One of the most common reason why you run out of a  power bank power to charge your mobile device is that when you go out, you forgot to fully charge your power bank while you was at home.

Not to mention that you also forgot to fully charge your mobile device too.

So, in this scenario you will lose all of your power fairly quickly.

Maybe you heard of a term overcharge, and you mean if you leave your power bank to charge overnight it will damage your power bank.

This is not the case anymore, because this days devices such as power banks, mobile phones etc. have built in protection from overcharging.

When they are fully charged, charging circuit simple turns off and stop charging your power bank.

So, it is very safe to charge your power bank overnight for example, to have fully charged power bank and mobile phone in the morning.

9. Be aware of what you buy

When it comes to a power banks not every one of them is created equal.

There’s a lot of known and unknown brand names, capacities and features to choose for.

In this vast sea of power banks it’s hard to choose the right power bank for your needs.

Some of them can only charge your phone once, but some can charge multiple devices multiple times.

If you choose power bank with most features and capability to charge multiple devices multiple times you will carry one giant piece of brick around.

But if you choose smaller once you will have much more portable power bank that you will be glad to carry around.

But, this will be determined only by your power bank needs. One more thing to consider is type of a power bank battery.

Most common ones are Lithium Ion batteries. They are cheaper and will have not such great capacity.

In the other side there are Lithium Polymer batteries.

They are more expensive, and they are larger in capacity and will have longer lifespan overall.

10. Ensure that a power bank is compatible with your device

Every mobile device have specific required charging rate in mAh.

Older devices requires about 1A of current, or a 1000mAh to get charged.

And for the most part you will be fine with any power bank, because all of them are capable of outputting 1A of electric current.

Tablets, for example are bigger and have larger batteries in capacity, so they require 2.1A of current to get charged.

In this case you must check your device and see if you need a power bank that can output 2.1A of current.

And one more thing, this devices requires 5V chargers.

From this we can calculate a required wattage that chargers are rated:

5V x 1A = 5 Watts

5V x 2.1A = 10.5 Watts

And this is especially important now days because newer type of connection and chargers are made.

And this is important because this chargers operates from 5V to 20V, and they can output  0.5A, 0.9A, 1.5A, 3A and 5A of current.

This is new type of USB type C connection.


This is also true for power banks too.

If your phone requires fast charging and your power bank can output only 1A, charging performance will suffer.

So, you must know your mobile device first before running outside to buy a power bank.

And yes, you can buy this types of power banks that supports fast charging, even if you have phone that only supports 1A of current.

11. To clean your power bank stay away from corrosive chemicals

Every once in awhile power banks get dirty and need to be cleaned.

We don’t notice this right away because it happens slowly over time.

Our hands are not perfectly cleaned, and we have oily fingers.

That oil transfers to a power bank while we holding it and then attracts dust and dirt.

If you think that you need some harsh corrosive chemical to clean this you are wrong.

If you choose to use this chemical you will ruin your power bank.

All connections are made from metal and it will oxidize fast and will become corrosive.

So, don’t do this to your power bank.

You might think that acetone will clean this dirt.

You are kinda right, but guess what else will happened?

Acetone is a strong chemical and it will melt plastic, and most of power banks cases are made from some kind of plastic.

And if this is done incorrectly it will embed dirt inside of plastic casing.

To clean dirt from a power bank you can simple use cotton swabs and isopropyl alcohol.

This is not corrosive and will it not melt plastic casing.

Make sure to handle your power bank with care.

12. When you buy a power bank pay close attention to capacity

When you are in a hunt for purchasing a power bank you will often see those huge numbers expressed in mAh.

This is a capacity rating of a power bank.

And I will be clear here, those numbers are way off.

When you see 10,000mAh (ten thousands) this is true, a battery of a power bank is for real that much.

But, what you will really get is about 80% to charge your devices.

They don’t include losses in this numbers, they just want to sound much better than they really are.

These 20% are lost through a heat to the ambience.

And that’s how it is.

You must include this losses when you buy a new power bank to make sure you get most of the power from it.

Also what I mentioned above, you must know your device you want to charge over a power bank.

This is crucial when you have a phone with fast charging enabled.

You want to buy a power bank that can output required amperage for your device to charge it properly with no issues.

If not, your phone will charge much slower than it should charge.

13. Don’t buy cheaper power bank

If the price isn’t an issue, always buy more expensive power bank.

If you’re new to power banks you might look at a two different brand names power bank with a same capacity ratings, but different price points, one cheaper and other expensive.

And you might just buy cheaper one because you didn’t know better to judge.

Be sure that more expensive one have everything better.

Build quality overall, electric circuitry, protection from shocks, battery, type of connections, number of connections, materials of connections, accessories includes etc.

Even if it have USB type C connection it must tell you something, I already talked about this type of connection above, so please check it out.

Even if you don’t have phone with a fast charging, you might invest money into a power bank that can fast charge your device, because at some point you will buy a phone with a fast charging built in.
