How Much Do You Know About Power Bank?
Mobile power, in the eyes of many people, a product which has no difference with a large-capacity battery, for us, it is not simply just a large capacity battery. For many consumers, the capacity, price, brand and appearance parameters of mobile power are designed to affect whether consumers ultimately purchase the product or not. However, this mini external battery, a product can supply and charge for various digital devices such as mobile phones, and MP3 additional, whether it is truly as simple as we think? Besides the indicated "capacity" we usually see on the packaging, the input and output voltage parameters, are there any factors affect the charging time? Below are some common and important factors that closely related to the working time of the power bank.
Beware of the Trap on the Power Bank Parameters
Every industry has its guild regulations and rules, so it is the power bank industry. Mobile power is a newly emerging industry in recent years, and this, for the domestic market, whether the government or manufacturers, has no norms and parameters of the standard related to a comprehensive mobile power industry production. And many mobile powers just have a few simple parameters of capacity and voltage and current marked on the outside of the package, so that more and more consumers inevitably will have more or less the misunderstanding and doubt when they are choosing and buying mobile power.
Mistakes: the Marked Capacity = the Available Capacity
The vast majority of mobile power are not marked the capacity of its actual output, so inevitably there will be some consumers will be stated on the packaging capacity mistaken mobile power is the actually output capacity, in fact, for example, a 20000mah external battery, the actual capacity it can charge the iPhone4S is 18,000. If you want to figure out this problem, firstly you need to work out the mobile power principle. The internal batteries provide power through the circuit board and rise, buck regulator circuit, and finally reach the output, during this process, the buck circuit plays a conversion role, in this process, the electronic components of the circuit board will inevitably loss out part of the energy of the batteries, and eventually form and waste heat. That is why many people find that their mobile power actual capacity does not meet the packaging label value.
Question: What's the Difference between Lithium Ion & Lithium Polymer Batteries?
Generally speaking, that lithium polymer battery of the same volume has a greater capacity than that of ordinary lithium battery, and it has better security, and the appearance can be made into various shapes and thickness. Compared with lithium ion batteries, lithium polymer batteries inside the electrolyte are solid or colloidal, so to a certain degree, the lithium-polymer batteries have a higher safety factor. Respectively, the simplest method to differ a lithium polymer battery is that its casing is usually made of relatively texture soft aluminum material, and it is relatively easy to get deformed, while the lithium-ion battery shell is generally made of hard texture of steel materials.
