How to charge a power bank

When our portable charger runs out of power, you must charge it if you wish to use it again. Unsurprisingly, there are more than a few options we can use to recharge the device. While we’ve listed those methods below, you should also be aware of some conditions that may affect its longevity. So continue reading if you’re still interested in finding out more about the best techniques.

In order to charge a power bank, you just simply need to insert the charging cable in the power input port

The power input port can be of several different types, but two of them are the most common: Mirco USB and USB type C. In order to be able to charge your power bank, you must first be sure that you have a compatible charging cable. You won’t be able to charge a Micro USB portable charger with a USB type C charging cable and the other way around. 

Furthermore, you should know that there also are different changing methods, depending on the power source you’re using. Let’s explore the several options that you have to top up your portable charger. 

Different charging methods 

Best one: Use a wall charger that can deliver fast charging

This is the best and most optimal option to consider, a wall charger compatible with fast charging technology. These often support QC2.0/3,0/4.0, PD 2.0/3.0, GaN, etc. It only takes a few hours instead of several more to reach a full charge, significantly reducing the waiting time. Not only that, but wall chargers with fast charging technology are also more efficient and usually have other features, such as overvoltage, and overheating protection. Keeping that in mind, these are also more high-quality, which ensures they will last longer.

Use a regular wall charger

A regular wall charger, rated at 5V/1 – 2A, will charge your power bank. It’s certainly slower than the ones that support fast charging technologies, so you should expect it to fully charge your power bank, which will take a few hours longer. This isn’t an ideal solution, but it still gets the job done if you don’t have a more efficient wall charger or the power bank doesn’t support fast charging technology.

Charge it via a laptop/computer USB

You can also charge your power bank through a laptop. However, a laptop’s USB port output power is generally quite low, rated at 5V/0.5A. So if you decide to use this method, it will take a longer time to fully charge, no matter the capacity and input rating of the power bank.

Charge it via the car cigarette lighter if you have an adaptor

A cigarette lighter is also another option you can consider if you don’t have anything else but your car nearby. You will need an adapter to use this method. However, depending on the adaptor you’ll use this method can charge your power bank very slowly.

Charge it via solar panels 

Charging your power bank via solar panels is a great go-to option if you’re on a camping trip. It can also be useful during emergencies where there isn’t a power outlet nearby. However, this method isn’t recommended for regular use because the charging rate, which depending on the sun’s intensity, can be very low. Therefore, it could take even a few days to charge your power bank.

Charge it via another power bank

Another option to consider involves connecting a secondary power bank to the power bank that needs to be charged. Using this approach isn’t an efficient solution. That’s because it results in energy loss and might cause internal issues that could potentially damage the charger’s circuit. If you’re still going for it, you should ensure that both power banks have the same capacity or that the device’s capacity is larger than the one receiving power. That way, it will be able to charge the power bank.

What to look for when charging a portable charger

Now that you know the multiple ways you can charge a power bank, here are some tips that you should know when doing so. These tips will help your battery bank have the longest lifespan possible

Try not to deplete it always to 0%. Stop at 15%

Your power bank’s batteries are under more stress if they deplete to 0%, which will cause a shorter life span since it uses more charging cycles. To keep it running while extending its life, you should wait until the power bank depletes to 15%. This will also ensure that your other devices efficiently charge through the power bank over time, so it decreases any chances of performance degradation.

The fastest charging time is up to 85%

Topping your power bank off at 85% is the best thing you can do to ensure the battery stays healthy. If you fully charge the device to 100%, then chances are, the lithium battery will degrade and see a capacity drop over time. That’s because batteries are under more stress when you attempt to recharge them fully, causing heat build-up.  

Don’t leave it in direct sunlight while charging

Leaving your power bank in direct sunlight while it’s charging could damage the battery. The added heat on top of the charging process can cause further issues to the power bank’s functionality. Plus, it can deplete its overall capacity. Batteries are best charged in an area where the temperature ranges from 5°C to 25°C.

Use a fast charger whenever you can

Using a fast charger is not only more efficient but also safer. That’s because fast chargers have built-in safeguards to protect your device. Plus, it will also charge your power bank a lot faster than a standard charger. To generate the best results, you should ensure that the power bank and charger are compatible with the fast charging technology.
