View Full Version : Generic notebook power adapter

11-10-2009, 01:22 PM
I've been looking for a second power adapter for my notebook. The supplied adapter has output of 19.5v ~4.7a. By my calculation, this supplies 91.65W. Does that mean that a 90W-rated generic adapter would by useable with my laptop (provided the connector fits)?

If so, how does this adapter look?

I've been using the Kerio Adapter for over a year and never had a problem with it. In the kit you get a lot of adapter tips, so there should be one that fits your laptop.

So is my assumption correct - a 90W-rated generic adapter will be fine for a laptop that uses an OEM adapter that has output of 19.5v~4.7a?

If you go to www.kerio.com.tw you can find your make and model of laptop and check for yourself whether or not the adapter can supply voltage and current required. In this model 11-15volts DC input. 15-24volts @6.0amps 90Watts (100max).

I bought one of these Kerio adapters to charge a test instrument whose replacement charger would have cost over $300, it works really well and has small plug in modules to set the charging voltage....for the price really good.

Have you tried laptopbattery (www.laptopbattery.co.nz)? You may find an oem item cheaper - or another universal!

Thanks - I had a look there a while back, but just checked again, and found this:

It's got the same ratings - 19.5v~4.7a, and it's 90W, but the compatible parts listing doesn't include the current genuine adapter I've got - VGP-AC19V36. How critical do you think that is?
