2, 44w: 44w charging speed is faster.

1, 18w twin engine flash charge: 18w twin engine flash charge using medium voltage output.
2, 44w: 44w adopts high voltage output.
Third, the charging power is different
1, 18w dual engine flash charge: 18w dual engine flash charge charging power is 18w.

I am glad to answer your question, 18w is definitely not 44w flash charge, 44w can provide faster charging speed, provided that your mobile phone supports this charging protocol, and now flash charge technology has been very mature, as long as support can be used, do not worry about the damage to the battery, now even 120w fast charge mobile phone there are many models, So a larger w number can bring more efficient convenience
