1, consider whether there is a problem with the charging cable, change a charging cable to see. When we buy a charging bank, we will be equipped with a charging cable. When we find that the charging bank cannot be charged, we should first check whether the charging cable is broken. The easiest way is to compare the data cable with the mobile phone. But this is rarely the case.
2, check whether the USB charging interface is firmly inserted, the first use of the USB interface is tight. In addition, the data cable can be replaced, or other mobile phones can try again to see whether it is normal, and you can also try again after charging the mobile power for a few minutes.
3, there may be a problem with the charger itself, for example, the external output current of the charging head is too small, you can try to connect the computer to charge, you can also try with a larger current 2A charging head. After some charging head is used for a long time, part of the fault will not be charged, it is recommended to replace the charging head and keep charging for more than 6 hours.
4. Is the charging treasure useless for a long time? Do not use mobile power for a long time, it is best to retain 50% of the state of power storage, if not, it is easy to break for a long time. In addition, it is recommended to charge the mobile power before using it for the first time, and it is not necessary to charge the lithium battery to full charge, let alone apply the power to run out. It is best to store the mobile power supply in a mild and dry place to ensure the safety of the mobile phone power supply.
5. The charging treasure enters the charging protection state, resulting in no charging. You can plug the charging bank into the USB output of the computer and charge it for 2 hours to release the charging protection state, and then it can be used normally.
6, the battery cell failure, generally because of bought second-hand goods or copycat goods. Batteries produced by Sanyo, Samsung, Panasonic, SONY and other large manufacturers are usually of good quality, safety and service life. The products of these manufacturers have been tested by the market, and the manufacturers have a certain technical strength, so the product quality is relatively high. In addition, choose some big brands, market reputation is better mobile power business can reduce the safety cost of use, unless the business has preferential activities, no low price products as far as possible not to buy. If consumers encounter problems soon after buying, quickly contact the business to return.
There may be a problem because the wireless charging bank needs to be fitted with a mobile phone or other charging equipment to transmit power, if the distance between the devices is too large or the location is not correct, it may lead to charging not into the situation, in addition, the battery damage of the charging bank, the charging cable interface is loose, and so on May also cause the failure to charge.
If so, check the fit between the devices, whether the position is correct, and whether the charging cable interface is loose, or try to replace the charging cable for charging.
Hello, the wireless charging treasure has electricity but can not be charged in it may be because the distance between the charger and the device is too far, resulting in low charging efficiency, or it may be that the battery of the device is aging and can not receive electric energy. It is recommended to charge the device close to the charger, or replace the battery of the device and try again.
If your wireless charger bank has power but cannot charge your device, the following problems may be the cause:
< br >
The distance between the charging bank and the device is too far, resulting in unstable wireless charging signals. It is recommended to place the charging bank and the device in a close distance.
< br >
The receiving coil of the device is not fully aligned with the transmitting coil of the charging bank, so that the charging signal cannot be sensed. Please check whether the alignment of the device and the charging bank is correct, and try to relocate it.
< br >
The internal coil or circuit of the power bank is faulty and needs to be replaced or repaired. Please contact after-sales service for repair.
< br >
The device itself has a hardware fault and cannot receive the wireless charging signal. Please contact after-sales service for repair.
< br >
To sum up, if your wireless charging bank has power but cannot charge the device, you need to conduct the corresponding investigation according to the actual situation.
There may be contact problems or life problems. Obviously, the wireless charging bank needs to be in close contact with the device to be charged, and if the contact part is not close enough, the power transmission may not be smooth enough to be charged. In addition, the wireless charging bank life is generally not too long, if the use of a long time, there may be insufficient power and battery aging and other problems, resulting in failure to charge.
Therefore, when using the wireless charging bank, it is necessary to pay attention to the quality of contact and replace the aging battery in time.
Possible reasons are as follows:
< br >
1. It may be that the charging bank interface has poor contact or there is a problem with the data cable. Try to reinsert the interface and replace the data cable connection;
< br >
2, it may be that the power of the charging bank is insufficient, try to recharge the charging bank before use;
< br >
3. It may be that the power management chip of the charging bank is burned or the battery core is damaged, and the corresponding parts need to be returned to the factory for maintenance and replacement.
It is possible that the power of the mobile phone is too large, and the power of the charging bank is too small. The charge won't go through. It is recommended to use high-power charging bank. Check the power bank again, is there a problem with the data cable? If the data cable is not connected, please replace the data cable.
Return.
Wireless charging bank may appear in the following situations: 1, the contact between the charging bank and the mobile phone is poor, resulting in no charging; 2. The charging interface of the mobile phone is damaged, causing the charging bank to fail to charge; 3. The battery of the charging treasure is aging, and the power is actually not enough to a certain extent; 4, wireless charging technology still has some compatibility problems, the compatibility between different brands of mobile phones and charging banks has not been well solved.
In order to avoid the above problems, when using the wireless charging bank, we need to keep the contact between the charging bank and the mobile phone good, try to avoid frequent plugging and unplugging of the charging cable, and do not use inferior charging bank and charging cable. In addition, keep the power bank full, don't let the charge too low to use, but also to prevent the power bank from overcharging, so as not to cause damage to the battery.
The reason why the charging bank cannot be charged:
1. The charging cable has a problem;
two
USB charging loose
three
There is a problem with the charger
four
The battery bank is dead
five
Charging treasure has a fault charging treasure charging solution: change a charging cable to see.
Reasons for not charging:
1. Whether the mobile phone model supports wireless charging or whether the wireless charger matches.
2. Whether the wireless charger indicator light is displayed normally.
3, mobile phone protective shell and other external factors of wireless charger.
4, wireless charger transmitter power, may also lead to wireless charging can not be used.
