Because individuals these days spend a significant portion of their time on smartphones, engaging in activities such as using applications, browsing the internet, taking photos, and more, it’s not uncommon for the phone’s battery to drain quickly. Whether the user is at home, work, in the great outdoors, or at a restaurant, their mobile companion is always active. To combat this issue, an external energy storage device known as a Power Bank was developed. It serves as a reliable solution for keeping the battery charged at all times, however, there may be instances where the Power Bank fails to charge the phone. This article aims to address all potential malfunctions and provide solutions to resolve them.
External battery and its correct choice
A Power Bank (a portable charging device) is a device used for storing energy that can provide power to your device when electrical outlets are not available.
A portable charger has become an essential tool for modern users, as it eliminates the worry of a low battery when using your device on the go.
Outdoor battery chargers are widely used in various situations:
- During tourist expeditions where access to power outlets is limited.
- During long flights or train journeys.
- For heavy use of the device when its battery capacity is insufficient for a whole day.
- When the integrated battery has a low power capacity.
It can be challenging to select the right external battery because they come in various sizes and have different features. For instance, some power banks are designed to charge only one phone, so if you want to power a larger device like a camera, you’ll need a more powerful external battery. Additionally, it’s important to keep in mind that the nominal power advertised by the manufacturer is actually 20 percent lower than the actual power, so it’s advisable to have a backup.
Amperage
The speed at which the Power bank can charge your device depends on its output power, measured in amperes. A higher output power means faster charging when using a compatible USB cable. You can choose a device with either 1A or 2A output power. While most smartphones can handle 1A, tablets require more power for a quicker charging time. It’s recommended to get an external battery with a minimum 2A current.
If possible, inquire with the seller about the device’s support for Quick Charge 1.O, 2.O, or 3.O. This feature allows for accelerated charging of devices that are compatible with this technology.
Please note that if the external battery is almost empty, it won’t be able to charge the smartphone.
The number of USB outputs significantly affects how many smartphones you can charge simultaneously using the external battery. The greater the number of ports on the Power bank, the more devices you can recharge at the same time. Typically, these power banks have either one or two USB ports. The latest and most advanced models now come with USB Type-C ports. In cases where the charger has two outputs, they often differ in terms of their current capacity, with one being 1 A and the other being 2 A.
It is possible to charge multiple devices at the same time, such as a smartphone with a 1 A output and a tablet with a 2 A output. However, it is important to note that charging two smartphones together will be faster than charging a smartphone and a tablet. For most daily usage, having just one port is usually sufficient.
The importance of the current input strength should not be overlooked, as it significantly impacts the speed at which the Powerbank is capable of charging from a 220V source. As per the standard, the current input strength ranges from 1A to 2A. The higher the value, the quicker your portable assistant will charge. It is recommended to purchase a unit with a current capacity of at least 2A.
Determining faults
If the charger has been recently purchased or has not been used for an extended period of time, it is recommended to recharge it for at least 10 hours. The issue lies in the fact that while the device was kept in storage and not utilized, the chemical processes in the battery may have significantly slowed down, a characteristic feature of lithium-ion batteries even when not in use. It could be the reason why the cell phone is not charging. By "rocking" the components that impede the battery’s functionality, they will break down, allowing the device to generate the required amount of energy. To confirm this, attempt to charge the smartphone.
At times, the charging process may begin and then abruptly halt. Given that many self-charging devices are imported from China, it is not unexpected for the indicated capacity factor on the charger to not align with its actual level. It is certain that a power bank with a genuine capacity of 2500 mAh will be unable to fully charge a phone with a 3500 mAh battery.
Port contacts
Due to elevated levels of humidity, the plates on the input ports and the contacts on the cable loop may undergo oxidation, resulting in a lack of necessary connection. There is also a possibility of the port legs breaking off the board, which can only be determined by dismantling the case, necessitating the submission of the Poverbank for repair.
Replacing a broken wire
If the USB cable is damaged, it is possible that the external battery is defective. Take a close look at the wire to see if there are any visible fractures or tears. If nothing stands out, try using a different cord to connect the battery and check if the mobile device works properly. This will help determine the problem. If the issue is with the wire, you can either cut out the damaged portion and reattach the remaining parts, or you can simply purchase a new USB cable.
Checking the power bank
The issue of underperformance in the Power bank does not always lie within the device itself. The problem can also be attributed to the deteriorated capacity of the smartphone battery, which fails to retain energy. You can diagnose this issue by charging the device using a wall outlet and using it for 30 minutes. If the battery charge drops by more than 50% during this time, it is advisable to replace the battery.
Running applications
Some mobile applications have a "bulky" backend that puts a heavy load on both the system and the processor. These processes consume a significant amount of battery power, even when running in the background, resulting in a slow charging process for the device. To identify which applications are draining a lot of energy, you can navigate to the "Applications" section in the settings, then click on the "All" tab, followed by selecting the cache view option from the submenu.
Conclusion
If your Power bank is malfunctioning, there’s no need to immediately rush off to get it repaired. The issue may actually be something quite noticeable, and we’re here to provide some assistance in identifying the problem.
