Today, there are many types of mobile phone chargers on the market, and they can be divided into high-copy, copycat, original, and fast charger, slow charger etc., so we want to choose good quality products among many mobile phone chargers, which is very difficult. Because we can’t check the wiring inside when we buy the mobile phone charger. So how do we distinguish the quality of mobile phone charger? Here’s what to explain:
First: understand the type of mobile phone charger
Mobile phone chargers generally have two charging measures, one is charging with a charger (the charger charges the phone battery through the connector); the other is charging the battery through the charging stand. Before purchasing, you should know the type, capacity and nominal voltage of your battery, so you can purchase the mobile phone charger that matches it.
Second: refer to the voltage and current of the mobile phone charger
At present, almost all of the batteries used in mobile phones are lithium-ion batteries with a single cell, a voltage of 3.6V, and a rated capacity of 500 mAh to 1000 mAh. Lithium-ion batteries have very high requirements on charging current and charging voltage; if the charging current is too large or the charging voltage is too high, the internal chemical reaction of the battery core will change greatly, causing the internal temperature to rise, resulting in damage to the electrode or diaphragm material or expansion of the battery core. . Although the general mobile phone battery is equipped with a protector with overcharge, over discharge and overcurrent protection functions. However, in order to achieve a good charging effect, a mobile phone charger with a maximum output voltage of 4.2V to 4.5V and a maximum output current of 600mA to 700mA should be purchased.
Third: see if the mobile phone charger has a certification mark
When purchasing a mobile phone charger, you should read the product manual or product labeling instructions in detail. In general, mobile phone chargers with product certification marks are guaranteed. Therefore, you should try to purchase products with product certification marks.
How to distinguish the quality of mobile phone charger? The standard mobile phone charger must have a certification mark, which is our first reference standard in the selection process. In addition, it is recommended that you purchase the products in a well-reputed and large-scale electrical appliance store.
