Charger is hot and smells is going on _ charger hot solution

1. This and the current intensity of the charger output; 500ma charger has become less and less common, now the output current is above 1A, and more charger current has reached 2A 2. Environmental temperature related;

3. The high temperature of the Battery Charger has a great relationship with the switch tube of the Li-ion Battery Charger. If the specification of the switch tube is not high, then the current will pass and the heat will be more;

4. The size of the Adapter Charger is also a problem. In order to make consumers easy to carry around, the charger merchants tend to pursue smaller products. As the volume becomes smaller, the heat dissipation performance becomes worse, and the requirements for electronic components are also higher. Take the capacitor, the high-voltage capacitor is smaller and smaller in terms of maintaining the capacity, and it is better in terms of withstand voltage and temperature. If the voltage is not enough, the capacitor will be broken, and the temperature will not burst enough. capacitance.

5. Cottage products are more likely to cause abnormal temperature rise. The stability of the output voltage of the cottage charger itself is not as good as the original charger, which will cause problems such as slow charging and serious heat generation of the charger.

At present, most of the domestic mobile phones use universal chargers, and domestic mobile phone brands such as Tianyu, Konka and Changhong have launched a variety of mobile phones that can use universal chargers. Compared with the high popularity in domestic mobile phones, universal chargers appear to be "low-key" in foreign-branded mobile phones. “Consumers are better off plugging old phones into universal chargers and not using universal chargers for other electronics.”

Since the universal charger adopts the USB standard interface, the user can carry the data line and connect with the notebook computer to charge the mobile phone. In addition, it provides convenience for data transfer between mobile phones and other devices, enabling multiple lines of use. To solve the repeated purchase of the charger, the most important thing is to unify the interface between the charger and the mobile phone and the charging voltage of the charger, and the published standards have not solved these problems. What they hope is that all chargers can be used in a uniform manner.

The smell of the charger is hot. The smell of the mobile phone charger causes the smell of the plastic case. Pay attention to whether it is a plastic smell. If it is, the insulation of the plastic case or wire inside the charger is melted. Don't use it anymore, it's easy to short-circuit a fire, or burn your phone, or it's easy to overpower.

It is recommended to observe whether the plug part of the mobile phone charger has ignited and oxidized blackening due to poor contact. Some need to be replaced with a plug with good contact. If there is no need to replace the charger with more power.

Be sure to use the original charger or charging cable. It is easy to use the inferior charger or charging cable to explode the battery. If it is overheated, it will cause a fire.

1. Charge in a cool environment.

If the phone charger is overheated, it is best to charge it in a cool environment in the summer, such as an air-conditioned room. This way the phone charger will not overheat.

2. Use the original charger.

When charging the phone, the original charger should be used, which ensures stable output current and protects the battery. The original charger will also heat up, but will not overheat and have protective devices. If your charger is overheated, it means fake or shoddy, or not original.

3. Do not play the phone while the phone is charging.

When the mobile phone is charging, playing the mobile phone will cause the mobile phone charger to overheat, because it will work for a longer period of time than normal, so that the charger will not, it will reduce the life of the charger.

4. Do not overcharge.

Generally, the original charger for mobile phone charging can be fully charged in about 3 hours. Do not continue charging after it is full. Otherwise, the charger will be overloaded and become overheated. Unplug the charger in time.

5. Be careful of the surrounding heat source.

When charging the mobile phone, the charger should be placed away from heat sources, such as gas stoves, steamers, etc., to avoid excessive ambient temperature, causing the charger to overheat.

6. Reduce the number of times of charging.

If you charge more than one day, it will cause the charger to overheat, so you should control the number of times of charging, usually one or two days to charge, can help extend the life of the charger.

7. When charging, the phone should be turned off as much as possible.

This will extend the life of the charger and protect the phone.

1 When the charger indicator is “green”, the battery is fully charged. At this time, the battery is in the floating state, and there is no need to cut off the power. It can also be used if there is an emergency and the indicator light is "orange".

2 Charger should avoid direct sunlight when charging, keep away from heat source, the charger case and bottom should not cover the items, should be well ventilated.

3 When charging with a charger, avoid contact with the charger for the elderly and children.

4 When the battery is charging, insert the charger output (low voltage) plug into the battery box socket, and then plug the charger power plug into the 220V/50Hz AC Power Supply. At this time, the charging indicator on the charger panel will be on and the charging is completed. After that, the indicator light turns to the floating charge indication, and the charger will automatically switch to trickle charge. After charging is complete, unplug the 220V AC plug from the charger input and then unplug the output. Keep your hands dry when plugging in and out.

5 The contacts exposed by the charger are charged. It is strictly forbidden to touch by hand or contact the two contacts with conductive materials.

6 When using or storing the charger, prevent any liquid or metal particles from penetrating inside the charger. Also beware of drops and impacts to avoid damage to the charger.

7 When charging, if the charger case is hot (about 50 ° C) or smells smoke, immediately unplug the power, stop charging, and send it for repair in time.

8 When charging, the red indicator light on the charger indicates that the charging is normal. Before the power is fully charged, the green indicator light is on, and it is best to charge the green light again after charging for 1~3h.

9 When charging the charger, do not place flammable or explosive materials on the bottom and do not cover anything. If there is odor or the external surface temperature reaches 65 °C, or the charger indicator light is red for more than 12h, or the battery generates higher heat, stop charging immediately and carry out maintenance.

10 Do not wash the body of the battery case with water when charging.
