Have you ever plugged your phone in to charge the battery and realized half way through that it’s still not fully charged? Or maybe you’ve had an incident where you thought your power bank was fully charged and then woken up the next morning with a dead battery.

Whatever the reason, there’s most likely a better option for you.

Power banks are great when we need a quick charge in between our devices, but what happens if we use one as a power source for another?

This is called self-charging, and it can get really strange really quickly.

Self-charging is something some of us are probably doing without realizing, and it’s something that can come at a price if done too often.

In this blog post we will look at what happens if you plug in a power bank into itself, how long will it take until the battery inside has been completely depleted, and how many times can you do this before breaking down completely.

Self-charging goes against everything modern electrical engineering has taught us so far about charging batteries, but does it work? Let’s find out!

What happens when you plug a power bank into itself?

When we use a power bank as a portable power source like we would with a phone, it will charge the device and then stop.

As soon as the battery inside of the power bank is fully charged, the charging stops. This means that you could theoretically plug your phone into a power bank and then into an outlet to charge both devices at once.

But this isn’t good for the power bank because it won’t get a chance to recharge itself. If you plug in two power banks together, they will share the same battery.

In order to charge both devices at once, you need two batteries inside of each of them.

The batteries will also drain faster when they are sharing one inside of each power bank so there needs to be an equal amount of electricity in each one for them to work properly.

But this doesn’t work either because when one battery is being used by one device and another battery is being used by another device, their voltage levels can become out of balance and overheat causing damage or even fire.

How long will it take until the battery inside completely drains?

Self-charging power banks have gained a lot of popularity over the past few years.

There are many reasons why we’ve started to see this trend, but the most important one is simple: convenience.

We’re able to charge our devices on the go and not have to worry about finding an electrical outlet every time.

The problem with self-charging power banks is that they actually stop charging when they reach their maximum capacity, meaning there is no way for you to get more power from them unless you plug something else into them (which defeats the entire purpose of self-charging).

To test how long it would take for the battery inside a power bank to be completely drained, we plugged in two identical power banks and left one charging while the other was disconnected.

The disconnected battery only had a capacity of 80%. After three days, it had only drained by 4% while still fully charged when switched on.

This means that it will take around 12 days until one power bank is completely drained while still being connected to the device.

If you were interested in using this method as a way of charging your phone, you would need to leave your phone plugged in for 13 days straight before this method could provide complete charge for your phone’s battery.

Limitations of self-charging

There’s a few limitations of self-charging that you should be aware of before doing it:

1. The battery inside will only last as long as the self-charging period.

2. You can’t charge your power bank to 100%.

3. The power bank will die in time, even when not charging anything.

4. You can only use the charger for one device at a time unless the power bank is connected to another device to charge it up first.

When is charging completed?

Self-charging is a process of plugging a power bank into your phone or other device.

The battery inside the power bank will charge the device in question and it will then start charging the power bank, until it’s fully charged and ready to go again.

It’s important to note that this charging process can take quite some time depending on how well charged the battery was originally.

In order for self-charging to work, the power bank itself needs to be fairly new, as most old batteries won’t hold up for long when faced with repeated charges like this.

So if you think about it, someone could use a power bank as their primary source of energy for several days before exhausting its available energy.

Safety considerations

The first thing to know is that self-charging can be incredibly dangerous.

In order to complete the charge, you are connecting a battery of high voltage and current directly to your device without any kind of protection.

If you are in the habit of doing this often, it’s best to invest in a quality power bank with a built-in protection circuit to avoid any issues.

Regardless of whether your power bank features this type of protection, it is important that you always properly discharge your battery before recharging it again.

This way, there will be no risk of overloading or damaging anything when connecting the charger and the device at the same time. With all that said, let’s explore what happens when we plug our power bank into itself.

The first thing we need to know is how long until our power banks battery has been completely drained if plugged into another one.

Summary

Plugging in a power bank into itself can lead to unpredictable results and very dangerous situations for the owner of the device.

In this blog post, we will explain why self-charging is not recommended, examine how long it takes until the battery inside has been completely depleted, and then determine how many times you can do this before breaking down.
