The maximum currents for these voltages is more than 5A. But this device will work with such current only during a few seconds (maybe minutes) before it go out of order, because any current more than 2.5 A is overcurrent. It is able to give you 60W without overload only at 24V. WARNING!!! It has no a real overcurrent protection.The mesured max. output current (Uin=230V) is about 8A at the low voltage, 5.5A at 15V and 4.5A at the upper voltage (24V). USE A FUSE!

It depends how thirsty your laptop is . While some small laptops may be ok with just 2.5 Amps some solid&bigger ones may need 3-4 Amps. So it depends on particular laptop. Voltage can be set to 19V no problem.

I've already asked a question "What is happened when the current is more than 2,5A?" but nobody answered it. I bought and tested this device and tried to answer it myself, unfortunately it's impossible. I've written a review 2019.02.03 with photos - but it wasn't published. So I'm answering here: WARNING!!! It has no a real overcurrent protection (may be overtemperature protection - I didn't check it).The mesured output current is about 8A at the low voltage, 5.5A at 15V and 4.5A at the upper voltage (24V). And, finaly, a question: where is my review?
