Product Comparsion-How We Definte A Product

Which one is more suitable for you? Product Comparison

If you think of a product, you are likely to think of a product in a simple way, such as the appearance of the product, but the product is more complicated than you think. We will use a power bank as an example to explain the inner part of the product to you.

Product Introduction

Below are three power banks that look the same. After our analysis, we hope that you will have a new understanding of the product.

 

A+ product / A product / B product

Why is the capacity of some mobile power banks clearly marked as 6000mah, but it does not meet the full charge of the mobile phone? The reason for the problem is that maybe the power bank you bought in other stores has a falsely marked capacity. For example, you bought 6000mah, but other stores give you a power bank with a package of 6000mah, however, the actual capacity is 3000mah. 
We are confident that this will not happen at Wowtechpromos.

So here we will compare 5000mah, 4000mah, and 3000mah power banks.

First of all, let's talk about its battery. The capacities of our three power banks are 5000 mAh, 4000 mAh and 3000 mAh. The larger the battery capacity, the heavier the power bank will be, which can also provide more charging times for the mobile phone.

This 5000mah capacity battery weighs 74.43g.

This 4000mah capacity battery weighs 70.72g.

This 3000mah capacity battery weighs 46.14g.

Charging

The speed of charging is determined by POWER, POWER =  VOLTAGE CURRENT, P (W) = U (V)  * I (A). The greater the input power, the faster the charging speed of the mobile power supply. The greater the output power, the faster the charging speed from the power bank to the mobile phone.

The following is about our product testing.

Input

The 5000mah Power Bank's input is marked as 5V/2A, and the actual test is also 5V/2A. The input power is 5V * 2A = 10W. 

The 4000mah Power Bank's input is marked as 5V/2A, and the actual test is also 5V/2A. The input power is 5V * 2A = 10W. 

 

The 3000mah Power Bank's input is marked as 5V/1A, and the actual test is also 5V/1A. The input power is  5V * 1A = 5W. 

Output

The output of 5000mah Power Bank is marked as 5V/2A, and the actual test is also 5V/2A. So the output power is: 5V * 2A = 10W. 

 The output of the 4000mah Power Bank is marked as 5V/2A, and the actual test is also 5V/2A. So the output power is 5V * 2A = 10W. 

The output of the 5000mah power bank is marked as 5V/1A, and the actual test is also 5V/1A. So the output power is: 5V * 1A = 5W.
