Yes, you can know that the charging treasure is generally from the Chinese charger voltage, charging the electricity of the mobile phone, talking about our charging treasure with various voltages are basically OK, do you know why? It is because he is through the charger, charger, charger, charger has a transformer role, how high China after the charger changes, can be, suitable for each power supply dominated by the same power, talking about our charging treasure can use 67 households of power, we all know that the principle of electric charging is like this, there is a transformer transformer can.
It should be okay. It won't hurt.
The 66w phone itself is designed to fully cope with the current and voltage of 18w charging.
If the situation is reversed and a 66w charger is used to charge an 18w mobile phone, it is really something to worry about.
You can cook small things in a big pot, you can't cook big things in a small pot.
I can only say that since using the 67w fast charge phone, my original 18w three charging banks have been enlarged a little.
Personally feel that the threshold is not the same, it is too high, and some charging treasure it needs over-voltage protection.
Charging treasure can be charged with fast charging, it is recommended that users choose a power adapter that matches the charging treasure. Fast charger voltage 12V\/9V\/5V, although you can use 5V\/2A current work, but once the charging bank input is only 1A, it is easy to use for a long time there are security risks, so if the consumer charging bank does not have fast charging function, then it is best to choose ordinary and matched charger
Yes, the power bank supports 67w fast charging, but the power may not reach 67w
