Problems solved by technology

The original power adapter is equipped with a transformer, which can automatically adjust even when the voltage is unstable, which is safer than the original charger, especially the cheap counterfeit power adapter, which lacks a protection circuit and cannot guarantee the stability of the current during charging. , it is easy to burn out the battery, shorten the service life of the battery, and even have the risk of explosion
[0004] At present, there is no relevant technical solution to help users purchase power adapters, which makes it difficult to protect users' consumer rights

Abstract

The invention discloses a detection method and a detection device of a power adapter, wherein the detection method of the power adapter comprises the following steps: obtaining a first voltage value of the power adapter, wherein the first voltage value is a voltage value when the power adapter is unloaded; gradually increasing a load resistance value of the power adapter, and detecting a difference value between the first voltage value and a second voltage value in real time, wherein the second voltage value is a voltage value of the power adapter obtained by detection in real time in the process of increasing the load resistance value of the power adapter; and recording a current load current value of the power adapter while detecting that the difference value between the first voltage value and the second voltage value is not higher than a pre-set voltage threshold value. The technical scheme provided by the invention can help users to select and purchase proper power adapters; and therefore, consumer rights and interests of users are ensured.

Description

Technical field [0001] The invention relates to the technical field of power supplies, in particular to a power adapter detection method and a power adapter detection device. Background technique [0002] The popularity of smart phones and the open development of the Android (i.e., android) system have led to the rapid development of mobile phones. Not only are copycats emerging in an endless stream, but also accessories are everywhere. Usually, the accessories that you want to buy are often paid for and not qualified. The product is a headache. [0003] In actual work in the city, the output current of the power adapter is determined by the load connected to the adapter (i.e. mobile phone). As long as it is within its power, how much current the mobile phone needs, how much current the power adapter provides, if the mobile phone needs it If the current exceeds the upper limit of the current that the power adapter can provide, the power adapter will always output this maximum curr...
