Many people say that when they go out, the sense of security is given by the power of the mobile phone. For many people, the most painful thing about going out is not not not not not bringing money, but bringing a mobile phone and running out of battery. At this time, the roadside shared charging treasure has become a "lifesaver for electricity".
So many shared charging treasures, how will you choose?
Some people tend to choose well-known brands and feel more secure. Most people tend to be close to each other and only want their phones to be charged quickly. In fact, different brands of shared charging treasures charging speed, battery capacity, and difficulty of return are not the same, which one is slightly faster? Which one is more cost-effective? Today, we take you to reveal the secrets one by one.
In order to help you avoid pitfalls, we have summarized some experience from the evaluation results of consumer protection committees and laboratories in many regions for your reference.
First of all, we must first understand the effective output capacity of the shared charging treasure.
01 "Effective Output Capacity" of Shared Power Bank
Simply put, it is the capacity that you can actually use when charging, and according to the relevant regulations, the effective output capacity at room temperature is not less than the rated capacity.
In response to this content, the Fujian Provincial Consumer Protection Commission has done an evaluation in 8 shared charging treasure brands such as Street Electricity, Meituan, Caller and Monster Charging, and tested the effective capacity of the final conversion output after multiple losses such as bucking, boosting process and protection circuit when the shared charging treasure works.
Through the evaluation results, we can see that the effective output power of the two products of the street power sharing charging treasure meets the requirements, and the pass rate reaches 100%; Among the products charged by Meituan, Lai, Xiudian, and Monster, 50% of the effective output capacity of the products is lower than the nominal rated capacity, and the effective output capacity of the two samples of Yunchong Bar and Xiaodian is significantly lower than the rated capacity.
The above results may explain why some charging treasures clearly show that they are fully charged, and they are dead after less than two hours of charging." ”

Note: The 2 samples of Soudian could not be tested due to the need for a dedicated charging case.
Hangzhou Consumer Protection Commission also did a similar test, the discharge capacity test results show that the discharge capacity of most charging treasures is lower than the rated capacity, only the discharge capacity of street electricity meets the requirements, the two test results are higher than the rated capacity, and basically tend to be consistent.
02 "Charging speed" of shared charging treasure
Another confusing question is, "Which brand of shared charging treasure charges slightly faster?" "Although it is not as fast as ordinary charging treasures, there should always be a fast and slow order.
In the evaluation results of the Hangzhou Consumer Protection Commission, we found that after 30 minutes of charging, it can basically reach 20% of the charge; When charged for 60 minutes, the street power shared charging treasure charged the highest power, which can be charged to 43% of the charge, followed by small electricity and double power (42%), compared to Meituan only charged 31%, and the monster charged 90 minutes to charge 41%.

From the above figure, we can also find that the charging speed of different brands is also very different, the shared charging treasure itself is an emergency need, it is recommended that you give priority to the shared charging treasure with a faster charging speed.
Based on the above evaluation results, whether it is output capacity or charging speed, the performance of street electricity is relatively better, and most other brands are not much different.
Finally, two more words, in response to other problems such as "difficulty in return, price chaos" and other problems that everyone complains about, we must also warmly remind you here that when renting a shared charging treasure, you must choose a brand with a higher reputation. On the one hand, product safety is guaranteed; On the other hand, well-known brands also put more devices offline, which is convenient for return; In addition, when scanning the code, it is also necessary to read the charging rules clearly to avoid unnecessary fees and troubles.
