1. Mobile phone wireless charging voltage is up to 15W. 2. This is because the common wireless charging technology on the market mainly uses the Qi standard, and its highest power is 15W, so the wireless charging voltage is correspondingly limited to 15W. 3. It is worth extending that with the continuous development of science and technology, wireless charging technology is also improving, and there may be higher power wireless charging technology in the future, so as to increase the upper limit of mobile phone wireless charging voltage.
The maximum voltage for wireless charging of mobile phones is generally 5V, because the output voltage of most mobile phone chargers is 5V. Wireless charging technology usually uses the principle of electromagnetic induction to transmit energy through electromagnetic fields, so it is necessary to maintain a low voltage to ensure safety and charging efficiency.
Higher voltage may cause overheating, battery damage and other problems, so the voltage of wireless charging of mobile phones is generally not more than 5V.
1, the mobile phone charger has been unified: output voltage is 5v, output current ≥500ma.
2, individual smart phone charger output current is larger, can exceed 500ma. But [the rated output voltage of the charger is absolutely the standard 5v] this is beyond doubt.
3, the voltage of the mobile phone battery is basically 3.6v(3.7v), its highest charging power
