With the increasing popularity of mobile phone digital mobile products, the charging treasure market has also developed rapidly in recent years, which can be said to be in full swing. It has become a habit for many people to go out and carry a rechargeable treasure. However, the choice is not good, charging treasure is likely to become a carry-on bomb. According to CCTV news reports, a few days ago, Guangdong Quality Supervision Bureau conducted a spot check on the quality of charging treasures in the province. The result showed that the failure rate of the spot check was as high as 36.3%. These charging treasures have the risk of explosion and fire besides the problem of false capacity.

So how to choose the best companion for mobile phone? What kind of charging treasure is safe? Here, several elements are sorted out as a reference for choosing charging treasure.

1. Look at the rechargeable battery

Charging treasure cores are generally divided into 18650 cores and polymer cores. Core quality is the most important factor that affects the quality of charging treasure and the safety of charging treasure. Low-quality electric core is the direct cause of potential fire and explosion of charging treasure. At the same time, the safety factor of 18650 cores is lower than that of lithium polymer cores. 18650 batteries are in series and parallel. If one of the batteries in the battery pack fails, the whole battery pack will be involved. For example, if one of the batteries has a low voltage, the voltage value of the whole battery will be lowered and the internal resistance will be increased. If the original current and voltage are still used for charging, it is very likely to cause the thermal explosion of the battery. Lithium polymer batteries are relatively safe.

2, charging capacity

When choosing charging treasure, the capacity of charging treasure should be considered. The capacity is proportional to the weight. Although the large capacity can charge the mobile phone more times, the heavier weight is not portable and the charging time is longer, which will cause trouble for travel and travel.

and the aircraft has requirements for the capacity and rated power of the charging treasure, which should not exceed 20000mAh; the rated power of the charging treasure should not exceed 100Wh without the approval of airlines; the rated energy of the charging treasure should exceed 100Wh but not exceed 160Wh, which can be carried only with the approval of airlines, but not more than two charging treasures per passenger. Generally recommended 10000mAh charging treasure.

3. Specification of the input and output of Charging Treasure

The item is also very important when choosing charging treasure. If the rated input of charging treasure is 5V/1A for 10000mAh, it will take more than ten hours for charging treasure to be fully charged. If the rated input is 5V/2A, it will only take about six hours. The gap is considerable. At the same time, the output power of Charge Po is also very important. Now users generally have mobile phones and tablets. Tablets have large battery capacity and relatively fast power consumption. If the output power of Charge Po is too low, the charging speed of Charge Po is not as fast as that of Tablets. We should choose the charging treasure to support 2.4A output.

The introduction of fast charging technology has greatly improved the charging experience of mobile devices. Similarly, it is necessary for us to choose charging treasure with input and output while supporting fast charging.

4. Supporting and filling while putting

Choosing charging treasure to support charging while placing is more convenient for us to use limited resources and save charging time.

5, charging protection function

Excessive or unstable current and voltage can easily damage the mobile phone. Choose a charging treasure with overcharge, overtemperature, overcurrent, overvoltage, undervoltage and short circuit protection, which can bring all-round protection for mobile phone charging.

6. Security authentication

When choosing charging treasure, it is also important to see whether the charging treasure has passed the certification. Generally speaking, CE, FCC, fire protection certification and RoHS certification are common certifications. When choosing rechargeable treasure, we should recognize it clearly.

7, other functions

There are more and more mobile phone digital products, so it is undoubtedly more popular to solve the pain points of different needs of users. For different digital products, combined with the user's different scenarios of the use of demand, launched a number of products. For example, Go Pro Charging Pool, MFi Certified Charging Pool with Apple Data Line, Charging Pool with Type C Data Line, etc.
