The biggest difference between 33w and 66w charging is that the charging speed is half slower, but the premise of this is to cooperate with a good charger and charging cable, different brands of charging protocols are not the same, if not matched, it can not be charged so fast, in fact, 33w is enough. Batteries charge too fast, generate too much heat and are easily damaged. In fact, the charging speed is not suitable for the wattage of the power supply is linear, because the charging strategy of different batteries is not the same, and it will be slow at the end, so it is good to be full within half an hour.
All belong to the fast charge, but 33w, can only be the highest power 33 watts, and 66 watts, the highest power is 66 watts, the charging speed is faster than him, but after the late their speed is similar. At the same time, the biggest difference between the charging power of 66W and 33W is that the power is different, so the power is different. 66W is larger, then the represented power supply is larger, and can drive a larger load.
The difference between 66W and 33W is that the charging speed is not the same, and the full charge time of 66W is half that of 33W. Regardless of whether they are different between the two, because they have corresponding functions, there is also an internal function of them, there will definitely be a difference.
The difference in charging power. 33w is also a relatively high fast charge configuration. 66w is a super flash charge, the charging efficiency is twice that of 33w, and it is generally configured for the flagship and sub-flagship mobile phones of the brand. You can charge your phone in half an hour.
