1. Security. It is still very important to use the security as a power supply product. After all, the explosion of the charger is not without it. We are not buying a time bomb. Every country will make compulsory certification for power products. For example, China is a 3C certification, and products that are generally certified by 3C are basically safe. So as long as it is not on the stalls or on Taobao's charger, there is generally no security problem.

2. Power. For the previous ordinary USB charger, the power is uniform 5V/1A, but the PD charger has more patterns, because the PD protocol can support up to 100W, so the choice is more from 10W to 89W. It can be said that PD chargers below 18W are garbage. Why do you say that? Because since the choice of fast charge, the choice of the PD charger is the ability to charge, the power is too small, at most, can quickly charge the phone, not enough to see. At present, the ideal one is the 45W PD charger, which can charge the mobile phone and charge the notebook. It can also be used to charge the Nintendo Switch.

 

3. Compatibility. As mentioned above, the PD charger we chose not only needs to be charged quickly, but also needs to be fully charged. Since it is necessary to fill it up, it is necessary to consider the issue of compatibility. What we need is great performance on every mobile device. Now some PD chargers will be compatible with QC3.0 fast charging.

4. Small and convenient. We don't ask for high values, but we must be good. The charger is still used for charging. Considering its practicality, it does not require much good looks, but it is convenient to carry.

 

5. Price. As an excellent PD charger, the price/performance ratio must also be taken into consideration. The higher the power of the charger, the higher the price. The price of the PD charger will be more expensive than the average USB charger, but it will not be particularly outrageous. Take 45W as an example, the price of an excellent 45W PD charger should not exceed 100 yuan.
