ive got a 12v socket on my boat does anyone know if these chargers are suitable for boats?

[Giant]

Yes. The charger won't tell the difference between a 12V socket on a car and a 12V socket on a boat.

[matty40s]

• Input Voltage: 11V DC-15V DC
• Power: 90W
• DC Output: 19V 4.74A

Those look to be the key information you need.

Yes, it looks like the right one.

At that price, who knows how long it may last!!

We had something similar off Ebay when we used to take our laptop on the boat. The Dell laptop didn't like it.

 

In the end we bought the proper Dell kit which wasn't cheap but at least it worked.

Beware of Dell laptops.

Some of them can recognise that the charger is not a Dell part, and will refuse to charge.

Don't ask me how I know this...

Join the club, but they do specify this one is for Dells

Mine came from Maplins and has a charge point for about 8 different laptops. But the voltage supplied is displayed in leds and is different for each one. It costs around £30 but worth every penny and charges no problem.

I've had several attempts at buying a pattern spare for a Dell laptop charger 12v version

 

Ultimately

1/ the Dell mains charger run off a 75w cig lighter pluggable inverter works

2/ one Maplin adjustable voltage psu worked -seems that having three pins at the cable end of the lappy plug is a good sign (voltage regulation right at the lappy)

 

I have probably a dozen chargers that will NOT charge a Dell even though they say they should.

 

The ebay link says specifically they work with a Dell but ...

[Giant]

The third pin in Dell chargers is used to tell the laptop the power rating of the charger (they had 65W, 95W, 125W options IIRC). If the signal isn't present the laptop will sulk, run slowly and charge at a snails pace.

 

I don't think it has any role in voltage regulation.

Post no 24 (4th down) in this thread refers to this

Just bought one of these for my Acer appears to be completely unregulated and made a serious attempt to fry my battery. Sent it back for a refund. Came to the conclusion that a cheap car laptop charger is a big gamble.

May have to bite the bullet and look at the more expensive regulated version.

 

If any one has used the maplin regulated version successfully I would be pleased to hear about your experiences.
