I have a Kerio charger which powers my 19 volt laptop in the 4WD. On my last trip to the
Kimberley, it stopped charging. However the Kerio light was still on, so it was receiving 12 volts from the battery.
I thought it might need a need 19 volt fuse. Problem is, I dont know how to test it to see if the 19 volt fuse is the problem. Also, if it is the problem, where do I get a replacement from? I tried Jaycar, but they only have amp fuses.
Does anyone have any ideas, as Kerio appears to be a Taiwanese company with no Australian office?

G'day Zebra400
Fuses are measured in amps not volts, if yours is blown it should be a simple task to check it with an ohm meter. Check the end of the fuse it usually has the amp rating on it.

All the Kerio fuses are marked with volts. You put in the relevant voltage marked fues based on your laptop power.
mine is 19 volts so I put the green 19 volt fuse in the Kerio.
So if I put the 18 volt fuse in, would I blow up my laptop, and is not, should I see it charging (if it is working)?

Zebra what your talking about is the voltage selector that you plug in to give the voltage to suit your laptop, basicly it's a resistor but looks like a mini fuse.
18v won't kill your laptop but your laptop might not recognise the lower voltage.... try and see at you own risk.

I have been using a Kerio Energy Knight II 90W for years with my notebooks. Toshiba, HP and acer. They are all rated at 19VDC input and I have always used the 18V (red) "fuse" with absolutely no ill effects. Why? - because I purchased it from DSE on special with no 19V "fuse".
The so called "fuse" is not in fact a "fuse" but simply a small resistor which controls the output voltage. It would be unlikely that this low wattage resistor has failed.
You should be able to check the output with a multimeter set to say the 20VDC range to determine any output fault.
I would suspect either a break in the output lead or internal failure. A real fuse if you were very lucky.

Kerio are in Taiwan, but if you Google and find their address, and contact them, I think you might be surprised at how helpful thay are.
I was able to source a new plug for one computer, and then I got a plug for a Dell, which powers the computer but does not charge the battery, owing to the small mindedness of Dell.
I have had nothing but good experiences dealing with Kerio direct. Even their broken English is enjoyable.
Give it a try.
