Now science and technology are advancing by leaps and bounds, and almost everyone in modern youth is using smartphones. The popularity of smartphones, the popularity of integrated design and the relative stagnation of battery technology have made mobile power a must-have accessory. So, how much is the mobile power supply? How to choose the best style in mobile power with different color shapes and different battery capacities?
To ask how much mobile power, depending on your choice and which one you are suitable for, according to different capacity and brand, the price of mobile power is also different.
Not all mobile power supplies are excellent. Let's take a look at a few key points when choosing a mobile power supply.
Buy a large mobile power supply or a mini model?
The key word for mobile power is "mobile", which means you need to weigh its size to define usability. Some tens of thousands of mAh of mobile power is often too large, although it can charge devices such as tablets, but lost mobility, they can be more suitable for camping, but not suitable for daily carrying. Generally speaking, it can satisfy the requirement that the mobile phone can be fully charged once (about 5000mAh) and the compact size will be a daily commute.
Battery capacity is key
Battery capacity is generally expressed in terms of "mAh" (mAh), and the number is naturally larger as possible. Before purchasing a mobile power supply, you should also know the battery capacity of the device you are using, which can also roughly convert the performance of the mobile power supply. For example, the battery capacity of the Apple iPhone 5s is 1440mAh, and a mobile power supply with a capacity of 5600mAh can theoretically achieve about 3.8 times of charging.
But in fact, the mobile power supply itself is also using a lithium battery material with self-discharging characteristics, plus the loss during discharge, the theoretical number of times of charging is basically impossible. For example, the 5600mAh mobile power supply can charge the iPhone 5s 2.5 times, which is already very good performance.
Output current, interface and control chip
Another parameter that cannot be ignored is the output current, usually expressed in "A" (amperes). The output current of the mobile power supply will determine the charging time and the applicable equipment. In general, the maximum current that a mobile phone accepts is 1A, while the tablet requires more than 2A. Therefore, when purchasing mobile power, try to choose products with dual USB ports and different output currents, such as 1A+2.1A configuration, you can meet the charging requirements of iPhone and iPad at the same time.
Since the mobile power supply actually uses an integrated circuit to control the discharge, the control chip is also important to be able to identify the state of charge of the device and change the behavior of the charger accordingly. In general, mobile power supplies with advanced features such as fast charging and excellent security protection levels use better control chips. Therefore, you can pay attention to these functions and prices at the time of purchase. After all, the price is one point, and the tens of dollars have a large capacity mobile power. In addition to poor battery performance, the control chip is usually extremely cheap and cannot provide good performance. And security.
Internal lithium battery quality
Although the mobile power supply looks similar, the inside is obviously different. In addition to the control chip just mentioned, the part that determines the cost naturally has the quality of the lithium battery itself. For example, the recently red Tesla car uses 7,000 Panasonic NCR 18650 3100mAh lithium batteries. When you buy, you can pay attention to what brand of internal lithium battery marked by the manufacturer. Of course, price is also a key, expensive is not necessarily the best, but low-cost mobile power with poor lithium batteries will not be very good.
The emergence of mobile power is convenient for many people. Through the above content, do you have a certain understanding of how much mobile power? With the above method, is it very easy to choose?
Cement Flower Pot are made by mixing magnesium oxide and brine, adding modifiers, and applying the mixed slurry on the glass mesh cloth to make the required flowerpots. This flowerpot is low in price, has various styles, and is strong and durable. Fine indoor decorations. This material can make flower pots of various shapes and colors, and is corrosion-resistant, acid-resistant, degradable, and environmentally friendly and pollution-free. The main raw materials for flowerpots are magnesium oxide and magnesium chloride.
Cement Flower Pot have the following advantages
