1.Analyze from the power supply equipment

We analyze from the power supply equipment above, if the direct power supply to the electronic products is the adapter, if it is to charge the battery, then it may be the charger, why say possible here, because for the requirements are not high, or the battery life or battery charging capacity requirements are not high such as nickel-metal hydride batteries in toys, some are charged with the adapter. Or for example, the mobile phone notebook charging is also an adapter, here is a special to explain, because the mobile phone or notebook because of the internal charge management circuit, so only need to use the adapter to power, their charging is actually the adapter plus charge management circuit to combine into a charger to charge the battery. Because they use two ways of direct power supply and battery power supply to power electronic products, when you do not need to charge, you can directly use the constant voltage direct current of the adapter to power the product, when you need to charge the battery, the constant voltage direct current of the adapter through the charge management circuit to charge the battery current, voltage and control the function of the current voltage. When the battery voltage is insufficient, the charger output is in the constant current state, when the battery voltage rises, the output will enter the constant voltage state, and when it rises again, the charger will enter the protection state.

2.Analyze from the indicator light

We distinguish from the working indicator light of the charger and adapter that the indicator light of the charger is generally different from the color of the indicator light after charging, that is to say, the indicator light of the charger can be turned, and the indicator light of the adapter can not be turned. The indicator light of the adapter is only a working state display, but with the concept of energy conservation and environmental protection, more and more adapters have gradually canceled the indicator light, which can reduce standby power consumption and reduce unnecessary power loss.

3.Analyze from the inscription board

We can get information from the nameplate of the charger and adapter. The regular power adapter will generally indicate the name of the power adapter or power supply on the nameplate, or will use the English adapter to indicate. The regular battery charger nameboard will also indicate the charger or such as lithium battery charger, nickel-metal hydride battery charger, lithium iron phosphate battery charger, lead-acid battery charger and other information, or will use English charger to indicate. Why has the author deliberately used regular as the prefix of the charger and adapter? Because many chargers and adapters in the industry are not standardized in the logo.

4.Analyze from the manual or specification

How do we identify the charger and adapter as a consumer in the case of not understanding the single point listed above can not be identified with the author, but need to identify several points, or sometimes also need to look at the product equipped with the manual, or the specifications provided by the charger and adapter manufacturers to identify.
