Hello everyone,
My laptop is HP pavilion g4 1117dx (adapter output: 18.5V, 3.5 A (max), 65W) and I would like to buy powerbank Viking Smartech II (Output: 20 V (19 V, 19,5 V compatible) 4,7 A (max)) (Most powerbanks have 19V output).
Similar issue is there https://h30434.www3.hp.com/t5/Notebook-Hardware-and-Upgrade-Questions/Can-I-use-a-90W-19V-AC-Adapter...
But I was unable to find service manual to my laptop, so is somebody able to tell me if I can use this powerbnak, or it is too much voltage for the laptop? Thank you.
