What to do if the power bank/Mobile Power Bank is broken? Teach you how to easily identify and maintain it

With smartphones being so ubiquitous nowadays, many people carry a power bank. Although power banks are widely used, many are at a loss when it comes to troubleshooting common issues. Some might choose to throw them away and buy new ones, but certain problems can actually be fixed by yourself! Let’s follow AiFAST to learn which power bank issues you can resolve on your own!

1. When the Power Bank Fails to Charge Your Phone
There are two scenarios where a power bank can’t charge a phone: either it’s out of power, or there’s a malfunction. AiFAST believes that malfunctions can be further divided into two cases:

(1.1) Poor Contact
If your power bank shows it has power but still can’t charge your device, the first thing to check is whether the charging cable’s connector has poor contact. Some non-reputable power bank manufacturers cut costs by including low-quality cables, which may develop connection issues over time. As a premium power bank producer in China, AiFAST suggests users try replacing the cable to see if charging resumes normally.

(1.2) Output Port Failure
If switching cables doesn’t work, but the same cable can charge your device when plugged directly into a wall adapter, then the power bank’s output port is likely faulty. AiFAST recommends contacting the seller for after-sales service rather than attempting DIY repairs to avoid accidents.

2. When the Power Bank Won’t Charge
If your power bank isn’t charging, AiFAST first advises checking whether the charger and cable are working properly.

(2.1) Checking the Power Adapter
First, test whether the same adapter can charge other devices besides your power bank. If it fails to charge anything, AiFAST concludes that the adapter is the problem.

(2.2) Other Possible Issues
If the adapter and cable work fine with other devices, the issue likely lies with the power bank’s input port or its battery indicator (e.g., charging but not displaying correctly). AiFAST suggests applying for after-sales service for repairs. If the warranty has expired, consider buying a new adapter—AiFAST offers high-quality charging adapters too!

3. What If the Power Bank Drains Too Fast?

(3.1) Natural Wear Over Time
First, understand that all devices degrade with use—power banks are no exception. After repeated charge-discharge cycles, the internal battery capacity noticeably diminishes. AiFAST reminds users that excessively old power banks may pose safety risks, so purchasing a new one is advisable.

(3.2) Fake Capacity Claims in Low-Quality Power Banks
The market is flooded with substandard power banks. AiFAST advises buying from reputable stores to ensure safety. If a newly purchased power bank drains abnormally fast, it’s likely a low-quality product. AiFAST recommends disposing of it promptly.

Note: Power consumption speed is relative. For example, if a 10,000mAh power bank only charges a 3,000mAh phone once before dying, it indicates either exaggerated capacity or inferior internal batteries. AiFAST power banks undergo strict market supervision and testing, earning widespread user trust for their accurate capacity ratings.

4. Abnormal Heating During Charging/Discharging

(4.1) Normal Heating
A well-made power bank shouldn’t overheat during use. High-quality models feature low-resistance components and temperature control mechanisms, so heat generation is minimal—limited mostly to the USB port within safe levels.

(4.2) Excessive Heating
If your power bank consistently overheats during charging/discharging, it’s likely a poorly manufactured product. AiFAST recommends replacing it. For assistance, message us via WhatsApp or other online channels.
