  FAQ ONE : What is an adapter? The adapter is an interface converter, it can be a separate hardware interface device, allowing hardware or electronic interface to be connected with other hardware or electronic interface, and may be information interface, such as: power adapter, tripod base switching components, USB and serial switching device. In computer, the adapter is usually built in the card which can be inserted into the slot on the motherboard (external is availabale) ... the adapter information in the card exchange with the equipment supported by processor and adapter.     TWO : Laptop power adapter 1. See whether the output voltage of two power adapters is the same, if they are not the same, then do not use.
2. See the power of the power adapter in the premise of the same voltage, the big power adapter can replace a small power adapter, but a small power adapter cannot replace the big power adapter, otherwise the adapter might be burned. (Adapter is a small transformer, so the output current is determined by the laptop; do not need to focus on current parameters)
3. Check whether the output plug specifications are the same.
4. If you are not sure, you can consult the laptop sale hotline, but the reply you get is certainly that you must use the same original model adapter.   THREE : Can mobile phone charger and Bluetooth headset charger be shared?
Using a mobile phone charger to charge the Bluetooth headset is certainly no problem. But you may not charge a mobile phone with a Bluetooth headset charger because the current is not enough, you can try, this depends on the phone's internal hardware circuit and the charging part drive settings, as long as it can charge, there is no problem, there is no burn out problem. But certainly even it can charge, the charging speed is slower than using a mobile phone charger.   FOUR : Are all power adapters universal? Not universal, different electric equipment, the adapter may not be the same, if your adapter is broken and want to change one, you must pay attention to see a label above the adapter, which is marked the voltage, current and interface types of your adapter. Choose alternative products based on the original product as the standard, otherwise serious consequences will occur, resulting in losses. Cause of the malfunction: the battery starts battery protection at over-discharge. Over-discharge battery displays full power on the seat charger and cannot be charged. You must believe that the new phone should be discharged in the first few times; in fact, it is no need, and too much discharge will cause this problem. Now the phone batteries are lithium battery, which have no memory effect, does not exist more charging times and battery capacity decrease situation.   FIVE : The phone charger flashing yellow light when charging, and does not charge, what's the matter? Cause of the malfunction: the battery starts battery protection at over-discharge. Over-discharge battery displays full power on the seat charger and cannot be charged. You must believe that the new phone should be discharged in the first few times; in fact, it is no need, and too much discharge will cause this problem. Option 1
Connect the charger to the cell phone, try to fold the charging cable charger by different segments, peel the parts which result in poor contact, gently pull the thin foreskin line inside, the poor contact one will disconnect, and then peel the foreskin and connect, and then wrap with electrical tape, then it is solved and finished OK. Option 2
The cell phone must be directly charged (seat charger does not work), and charged for more than three hours, and then it is ok, the battery can be used normally, which has no sequela. Option 3
If you have good practical ability, you can truncate from the charging port terminal, and change an intact line, this method is troublesome, which is not recommended. Cherish the battery, and less use seat charger. Direct charge is conductive to the battery maintenance
