A power bank for charging a phone, laptop or other devices of small capacity can be used only after a certain amount of electricity is accumulated by the battery.
If, for unknown reasons, the external battery is not charged, then you will need to find out the reason for this non-standard "behavior". This article will explain why a power bank might not charge.

Reasons and methods for solving them
There are many breakdowns and deviations in the operation of the device, due to which the portable battery may not charge. Broken wires and a faulty charger are the most common causes, but there are also “original” states of this type of electronics.
When trying to find out why the bank is not charging, you must first take the simplest steps to detect the problem. In some cases, it may be necessary to disassemble the product and replace the rechargeable elements. This is an extreme measure that should be resorted to only when other repair methods have not yielded a positive result.
Power Bank generally stopped charging
If the charge of the bank turns off from time to time, then such a breakdown can be very difficult to determine. When the portable battery stopped charging at all, it is enough to carry out diagnostic measures, after which in 99% of cases it will be possible to accurately determine the cause of the malfunction.
Lack of electricity in a network
If, when the portable battery is connected to charging, it does not start to charge, or the process abruptly interrupted during charge recovery, then before taking any complex actions, you must make sure that there is electricity in the network.
In some cases, it is not enough to determine the availability of electricity in a house or apartment. If previously a powerful electric device was connected to the socket, then the contacts could burn out, so you should definitely make sure that this element of the electric valve is working.
Wire problems
If there is current in the network and the outlet is working, the problem may be a broken wire through which the power bank is connected to the adapter. If the external battery is manufactured by a well-known manufacturer, then the connecting wires included in the device are very high quality.
In a situation where a device of a less hyped brand was purchased, in order to completely eliminate this type of breakdown, you should use a known-good adapter.
Oxidized plug or plug
Oxidation is more often observed in devices that have been in use for a long time, but some newer banks may have contact sealed with foil.
In the presence of an oxidizing dielectric layer, which prevents the penetration of current into the device, the problem is easily solved by cleaning the contacts with a cotton swab moistened with medical alcohol. If the factory film is installed, then it is enough to remove it to completely restore the operability of the external battery.
Controller issues
Controller malfunctions are one of the most dangerous, because such a breakdown can lead to a fire of the device if the supply of charging current does not stop on time.The failure of this element can also occur in the complete absence of the supply of electric current to the battery contacts.
If there is such a malfunction, you will need to disassemble the bank and solder the new controller. New parts can be purchased relatively cheaply on Aliexpress. Work on the soldering should be done very carefully so as not to accidentally short-circuit or reverse the wires.
Open circuit
This malfunction is almost impossible to diagnose without disassembling the product body. An internal circuit may break as a result of the device falling to the floor, increased vibration loads, or poor-quality factory soldering.
When the case of the bank is disassembled, it will not be difficult to detect a malfunction. Detached wires can be seen even without the use of measuring instruments.
Aftermarket power supply
Most models of banks have built-in protection against the supply of electric current of inappropriate parameters. If there is a suspicion that the inoperability is caused by the use of non-original charging, then the current indicators should be measured.
Ordinary usb adapters have a voltage of 5 volts on the contacts and a current strength of about 1 ampere. If the value of the charging current differs from these parameters or the device must be charged from a higher voltage, then you should purchase a suitable charger and charge the external battery only from such a device.
Deep discharge
If the bank is completely discharged and after that does not respond to the charging connected to it, then most likely it will not be possible to fix such a device.
This kind of trouble most often happens with portable batteries that have not been used for a long time. Lithium-ion batteries are not subject to long-term storage in the complete absence of an electric current reserve.
After connecting the charging to a faulty bank, as a rule, only one indicator flashes. In this mode, the device can be kept indefinitely connected to the memory, but the battery will still not be charged.
Already fully charged
The opposite situation, when the battery is fully restored, but the charger was not disconnected, can also manifest itself as a malfunction. Inexperienced owners of this type of equipment can consider the lack of flashing indicators a serious breakdown. In this situation, all the lamps are on at the same time, but this is only a signal to disconnect the device from the power supply.
External battery does not charge fully
The bank may not be fully charged if a charger of insufficient capacity is used. For example, even the adapter from the iPhone is not able to qualitatively restore the external battery designed for laptops.
Such a malfunction can also be observed in case of malfunctions in the controller configuration. If the product was not manufactured correctly, the safety device will turn off the supply of electricity to the battery before it is 100% charged.
A brand new Verbank is not charging
A new bank may not be charged due to factory defects. If the controller does not even turn on and does not charge the battery, and the drive, in turn, does not give off electricity, then an attempt to independently eliminate the cause of the malfunction will void the warranty on the device.
In some cases, the contacts of the bank may be covered with a protective film. It will not be difficult to see such an “obstacle”, besides this, the instructions for the device must necessarily contain information on how to properly connect to charging for the first time.
If the bank does not charge, then the cause may be the malfunctions described in this article. In most cases, the recovery of the external battery can be done by yourself.
