How to choose and purchase Mobile Power supply some skills in portable battery's selection and purch
Now there are many brands of mobile power on the market, which brand of mobile power has become the most concerned issue, how to judge which brand of mobile power is good? In the absence of uniform industry standards, the purchase of high-quality mobile power has become a headache for consumers.
How to choose and buy mobile power supply.
Now there are many brands of mobile power supply on the market, but generally people pay attention to the brand, portable, shape and battery capacity, but do not really consider the performance of the mobile power supply itself, such as whether there is a false mark in the capacity, the type of battery and the material used, whether there is overload protection, whether the power control system is perfect, and whether the conversion rate is higher than 80%. All these are worth thinking about. Which brand is good for mobile power supply? How to choose and buy a high-quality mobile power supply comes down to five aspects:
1, whether the technology is excellent: the first is the mobile power supply lithium polymer cell, and the second is the lithium ion battery. Now there are many mobile power sources on the market that can disassemble a lithium-ion battery cell at will. We can all see that the cell it uses must be 18650 steel shell lithium battery. 18650 means the battery is 18mm in diameter and 65mm in length.
18650 uses lithium cobalt oxide as the cathode material, the nominal voltage per unit is 3.7V, the charging voltage is 4.2V, and the capacity is above 1000mAh, which is also the type of lithium battery used in notebook batteries. On the Internet, it has been seen that some black-hearted manufacturers have repackaged the cells on the waste notebook batteries and used them on the new mobile power supply, but from the appearance, it is impossible to tell whether the cells are good or bad at all. This is one of the reasons why I do not recommend lithium-ion batteries as mobile power sources. When it comes to such a product, even people in the industry will get it wrong.
2, efficient use: the standard capacity of the battery and the actual charging of mobile phones and digital devices are not 100%, and the "mobile power protection board" plays the most important role in the mobile power conversion rate, so if a mobile power supply PCB circuit board uses better workmanship and design, the battery is also excellent, and has a solid protection circuit. Then the quality of this mobile power supply is guaranteed. In my opinion, the conversion efficiency of a qualified mobile power supply should be at least 80%.
3, the appearance is novel: I believe that most people have to look at the appearance when choosing any product.
4, convenient and practical: light, compact and easy to carry, realizing power supply anytime and anywhere, which is also the most basic attribute of mobile power supply 5, safe and reliable: whether it can intelligently display the amount of electricity, no-load automatic identification shutdown, short circuit, overcharge, overdischarge, constant current, constant voltage protection. Ensure the safety of mobile power supply.
