Lenovo notebook power adapter 19v can use 20v of it
As long as the current enough to be able to use!
Yes, the general power adapter output voltage will have an upper and lower limit (no load and load voltage), about up and down about 5%. But not recommended for long-term use.
See if the adapter is suitable for the equipment, the following three conditions for reference:
1. The output voltage of the adapter is the same as that required by the device.
2. Is the adapter's output current consistent with the device requirements? (Or a little larger or smaller current is also not.)
3. The size of the joint is appropriate. (If the connector is too loose, will be bad, excessive fever.)
Hello, the electrical performance parameters are inconsistent Power adapter It is recommended that you do not mix, different machine configurations may be different, the required power supply environment is different, the use of non-matching adapter may cause damage to parts, we recommend that you use the original power adapter.
