The difference between 25 watts and 45 watts is mainly in the charging speed and charger power.
First of all, the fast charging 25 watts can provide higher current to speed up charging compared to ordinary chargers, so more power can be charged in the same time.
The fast charge of 45 watts is faster than the fast charge of 25 watts, which can fill the battery faster. Secondly, in terms of power, the fast-charging 45 watts of power is higher, and electrical energy can be converted faster, thus greatly reducing the charging time.
From the use of experience, the different power of the fast charge is suitable for different scenarios and needs, if you need a fast enough charging speed, and to take into account the charger size and portability, fast charging 25 watts is very good; If you want a faster charging speed and don't care too much about the size and weight of the charger in the bag, a fast charge of 45 watts is more suitable.
There is only one difference, one charge fast, one charge slow, 45W charging is certainly much faster than 25W, there is another difference, buy 45W alone than 25W other there is no difference. Charging fast depends on whether your mobile phone is fast when you buy it, it is fast, use your original charger to charge your mobile phone quickly, the mobile phone has a fast charge, if you take an ordinary charger, it is not possible.
The difference between 25 watts and 45 watts is the charging speed and charging power. The charging speed of 25 watts is relatively slow, which is suitable for charging low-power devices, such as smart watches, wireless headphones, etc. The fast charge of 45 watts is faster, which is suitable for charging high-power devices, such as smartphones, tablets and so on. At the same time, the use of fast-charging 45 watts of equipment needs to have the corresponding fast-charging technical support.
The difference between fast charging 25w and 45w is: 1. The power of the charging head is different. 2. Charging speed is different, 3. Output current is different. 4. The power of the load is different. 5. Different sizes.
Among them, 45w fast charge is higher than 250,000 fast charge. It's nearly twice as powerful, so it charges faster and has a higher output current. For example, charge a phone with a fast charging feature at the same time. From 10% to 95%. The 45w fast charge will fill up in about an hour and 15 minutes. A 25w fast charge takes about two hours to fill. It's also bigger. Due to the increase in power, the power of the components used is large, so the volume of the components is also large. The volume of the entire charging head is about 1.5 times that of 25w. In addition, it carries more power load.
