The knowledge of fast wireless charging 2

Q2: Wireless quick charge requires the right charger
A2: At present, most of the wireless chargers on the market do not match the charging heads. The chargers of ordinary "quick charge" 5V2A cannot provide wireless quick charge to Samsung mobile phones, but must choose the chargers that support QC2.0 or QC3.0 quick charge protocols.
In addition, the output current of mobile power is generally 5V 2.1a, and the wireless charger cannot be charged quickly.
Therefore, to realize the 10W wireless quick charge of Samsung mobile phone, it must be equipped with the charger of QC2.0/QC3.0.
Apple's wireless quick charging standard is 7.5w, and it needs to be equipped with a 9V gear of fast charging appliances (such as QC2.0/QC3.0) to support wireless quick charging. Therefore, if you use Apple original charger 5W(5V 1A) or 12W(5V 2.4a) of Apple tablet original charger, you cannot support Apple 7.5w wireless quick charging.
