LCD screen display
Mobile power with LCD display, and design considerations from the aspects of appearance, environmental protection, portability, etc. Generally, pure cobalt batteries are used to reduce the error of power display.
AC plug type
A mobile power supply with a folding AC plug is also called a folding in-line mobile power supply. It can be directly plugged into a household socket to charge the product itself. It integrates the functions of a charger and a mobile power supply, which is more practical and portable.
The mobile power supply with LED lighting and charging function is currently the most common on the market. This type of mobile power supply has a large capacity and is equipped with LEDs to facilitate lighting in low light conditions, which is very suitable for professional external power supplies.
It is the most important part of the mobile power. The quality of the battery basically determines the quality of the mobile power. The polymer battery is an aluminum plastic film shell, which will not explode under any circumstances, and has high safety performance.
The conversion rate of mobile power is very important. If the conversion rate is too low, it means that the line loss of the mobile power will be very large, it may heat up, and even explode. Generally, products with a conversion rate of about 85% are very good.
Generally, the capacity of the battery cell is directly proportional to the volume. The larger the volume, the greater the capacity. Try to choose a product with a large capacity under the same volume.
Output voltage / current
The output voltage must require 5V. The discharge current theory is also to be as large as possible, and charging is faster.
Charging voltage / current
The charging voltage generally requires 5V, and universal mobile phone adapters can be used. The charging current theory is that the larger the better, the faster the charge. Actually pay attention to the problem of fever.
Fast charge is the abbreviation of fast charging technology. In simple terms, it can be charged more quickly, and everyone who has learned physics knows the formula of P (power) = U (voltage) and I (current). There are only three ways to go: 1. Increase the voltage; 2. Increase the current; 3. Increase both at the same time.
