Yes, a 65W laptop can be charged with a 20w charger. But first of all, the interface should be consistent, and then you can use other chargers to charge, but be sure not to turn on when charging, so that the computer is fully charged before use.
For business travelers, a charger can charge mobile phones and computers is best, so that you can directly reduce the portable charging equipment, especially the charging head of many computers is very large, it is inconvenient to carry, as for the charger mix is actually completely feasible.
Agreed. Apple's original 20W charger can charge the MacBook Air, but it's only a little slower, and it takes about five minutes to go from completely empty to boot. So by definition, anker's 20W should work.
Although Apple's official fast charge and Anker are 20W fast charge, the power of the two products is not exactly the same in actual measurements. Measured Apple official fast charge can output up to 15.09W power, and Anke can reach 17.16W power, compared with Apple, Anke's power output is higher.
This is not possible, only high compatible with low, 20w with 65w notebook.
