Mobile phone power supply has been used by many people, it is a matter of something, there is a problem, and can not completely deny the mobile power supply of this mobile power manufacturer is not good, a thousand of the best products, will also flow out A defective product, even a global brand like Apple does not guarantee that the use process will not be a problem.
Is your mobile power supply a fake?
When you encounter this problem, you must first look at the mobile power in your hand. Is it genuine? We don't have the instrument to detect it. We can't go to any store to buy it at the moment. Then we only have to feel it first. If you find that the mobile power and appearance are very different from each other, then it will be faded, paint-painted, etc., then no doubt, the mobile power you bought is inherently problematic.
Some mobile power sources are unreliable, some are fake brand-name mobile power supplies, so don't use mobile power for a long time. That kind of product is a temporary emergency use, charging the phone or using an authentic original mobile phone charger.
The above prompts that there is power, why is there no response?
There may be a battery loss, or the voltage is too high. If the test is degraded, you can find a universal charger with an indicator light. This is the universal charger that can be lit when the battery is put on. Do not plug it into the socket. If the light is on, it proves that the battery is not losing power, but the contact is bad or the voltage is high. If some mobile phones detect that the battery voltage is higher than a certain value, it will not be turned on. What is your battery? No more can be analyzed according to the model.
If you have power, it may be that the voltage of the battery is not enough. For example, your mobile phone battery has 700 mAh of power, and you have 800 mAh in your mobile power. When the battery power of the mobile phone is 750, the mobile power is also Only 750, this 750 is not in the mobile phone, because the mobile power supply has a lithium battery protection circuit inside, and a boost circuit that raises the voltage of the lithium battery to the charging voltage of the mobile phone. Only the voltage of the mobile power source is higher than the mobile phone. To charge the phone.
Summary: Mobile power is generally less problematic. Most of the problems are caused by a problem with the circuit board inside, or the mobile power supply has reached the end of its life, and it cannot be stored. No matter what kind of problem is not solved by our users, this is only sent to the warranty, or to the mobile power supply.
