Laptop power options

Recommended Posts

Hi all, I am wanting to put a laptop in my boat for chartplotting etc. What is the best way to provide power? I don’t have an inverter at this stage and I know they are very inefficient especially so as I would be converting 12-13v to 240v and then back down to 16v.

Not really a solution to your power problem but maybe a tablet would be easier ? Most can charge off 12V.

 

I use an iPad to run navionics , works a treat and very portable and easy to use with touch screen

Before I started using an iPad for mostly all nav I went down this road

Tried 300w inverter but as you say not very efficient

Then managed to find a laptop that actually ran on 12v but these aren’t easy to find and limit your options

If I was to do it now would try something like this. https://www.ebay.com/itm/STEP-UP-Transformer-12V-to-16V-10A-160W-DC-DC-Power-Converter-Voltage-Regulator-/301916994954

Get a car charger (DC to DC converter) for your laptop. Easy and efficient. If you read what the output is on the mains charger (like 19v 2a or whatever) you can match that with the car charger. Any decent computer store, jaycar, etc

I got a 12v car charger for a HP laptop on the boat - works great.

 

I think I got it from PB Tech - be careful about the el cheapo ones from Jaycar.

 

The one I got also has two USB ports on it. very handy.

We have a Samsung tab A, does the phone as well as bluetooth to the battery monitor, wifi to the MFD email and annoying people on this website. Bloody thing has come close to sleeping with the fishes a few times but would be lost without it. As Eruptn says. Best thing is they have no power hungry inverter power supply. Incidentally, put a 3 amp fuse in your laptop power unit on the OUTPUT as they are not protected for some reason.

Thanks all. Personally not a fan of tablets. I have had a play with a few and have found the small, smudged, hard to see touch screens tend to annoy me. I have a small gps/plotter in both the cockpit and the cabin but the laptop will give me proper plotting ability and a bigger screen to look at. Hopefully power consumption isn’t too excessive
