A 65w charger can charge a 33w mobile phone, but the charging power may not reach the 33w fast charging effect.

Four steps to check whether the mobile phone charger supports fast charging:

1. Check that the phone supports charging power and fast charging protocol.

2. Check whether the mobile phone charger supports the charging protocol of the mobile phone.

These two steps mainly depend on the protocol matching between the mobile phone and the mobile phone charger: that is, the protocol supported by the mobile phone is consistent with the protocol supported by the charger, such as whether to support USB-PD, QC2.0/3.0/4.0, FCP, SCP, AFC, etc., The agreement is the same. If it does not match, many can be charged, but the power is very small.

3. The charger power is greater than or equal to the maximum power of the mobile phone: if the mobile phone is 27W, the charger must be greater than 27W.

4. Data line current size and voltage: see if the data line can reach enough current and voltage.

In theory, when the charging protocol supports it, a high-power charger can charge a phone with a lower maximum supported power at full speed.

Summary: The power of the charger 65W is greater than the charging power of the mobile phone 33W does not mean that 33W charging will be possible. First of all, it must be clear that the mobile phone fast charging protocol is perfectly supported by the charger, and secondly, the correct charging cable must be used, so that your mobile phone fast charging can play its role. his own greatest effect.
