12v Laptop Charger

[Kez165]

Hi Guys, I am totally new to all of this so I'm hoping someone cleverer than me can answer my question?

I have just picked up my new T6.1 and I am looking for something to charge my laptop from the 12V socket.

I have brought a Dell Inspiron 14 5000 2 in 1 and on the 240v lead it says 45w of delivery power so am I right in thinking I can buy the following product and use that? I currently have a 3.0 USB type A into type C cable (the USB C end will go into my laptop) - would this work?

There are so many options I'm all a bit confused with it all and to be honest I just need someone to tell me what to buy so I can power my laptop haha!

Here's the charger I'm looking at buying:

VELD VC48DG Universal USB Car Charger

48 W; USB-C / USB port connections; Fast charging technology

www.currys.co.uk

And I have attached a picture of my normal household charger.

Hopefully someone uses something similar?

That will only work for you if the power input on that laptop is USB-C

 

[Kez165]

Hi, thanks for the reply. On the Dell website it states my USB C type supports power delivery so am I right in thinking I can charge via the USB C?

Yes, as long as the adapter you buy and the cable between it and the laptop is PD capable.

okay perfect, thanks for your reply.

I'm interested to know if this worked @Kez165
I have a Dell laptop that runs on USB C, I bought the following from Amazon;
PD Type C Car USB Socket 18W and QC 3.0 12V/24V Car Power Outlet Waterproof 64W Dual USB Charger Socket Power Delivery 2.0 Quick Charge 3.0 36W for Marine Boat Motorcycle RV ATV (Green): Amazon.co.uk: Electronics

On my wife's Macbook Pro, the voltage/ power isn't enough and it pulses on and off, absolutely nothing on the Dell laptop.

 

[Dellmassive]

18w type 3.0 isn't enough power to charge a laptop i don't think.

Pd says 36w PD.... ?

 

[OllieGBR]

Yes, I misread the description and mixed up the USB with USB C.

Looking at my Dell laptop charger it's 65W;
20v/15v/9v/5v at 3.25/3/3/3Amps

I need to find an alternative.

Thanks as always @Dellmassive

Ollie.

If you look at the spec of a laptop USB C charger, it outputs a range of voltages, not just 5v.
Most phone USB C chargers just put out 5v.

I've got the older 45W version of this 12v PD . .

this one says 112.5W : https://amzn.to/3qGN4QB


do you need a chassis mount one>?

This looks beasty enough, I'm looking for a permanent fixture though. Could be an interim option.....

 

[Dellmassive]

90w is a lot of power....

That may generate a bit of heat....

I'll keep an eye out for a panel mount version.... I could do with the same for PD - charging the ALLPOWERS box. (65w plus)

Hi Kez,

I may be wrong [Edit: I am... see below ]... but I've never heard of a laptop that can itself be charged via its USB port, a standard USB doesnt normally allow for 'incoming' power.
Can you post a closer photo of the mains power-supply label please, the important info is the very first line of text directly under the white line.
I cant quite make it out, it looks like "OUTPUT 13.5v ??????" Laptop supplies are usually around 18 to 19v, but if yours does read 13.5v you could
have a lead made up to plug straight into a cig lighter socket. Otherwise you need a 'boost regulator' to get 18v from your 12v system.
Or, and this may be quicker & easier, just buy a small sinewave inverter, 100 watts or so, and plug the mains power-unit into that
Cheers
Phil

The newer (USB3/-C -PD 2.0 ) PD port can carry power unto 20v @ 5A apparently (upto 100W)


but 45w & 60W are more common atm


its important to not that aswell as the charger/device needs to meet the PD spec (ie 100W ) - So Does the connecting cable !! ie "PD-PD 100W"

i have this one for my 60 W kit : https://amzn.to/2Nqj0dP







All USB-C cables must be able to carry a minimum of 3 A current (at 20 V, 60 W) but can also carry high-power 5 A current (at 20 V, 100 W).[10] USB-C to USB-C cables supporting 5A current must contain e-marker chips (also marketed as E-Mark chips) programmed to identify the cable and its current capabilities. USB Charging ports should also be clearly marked with capable power wattage.[11]

this example is a 90W Dell charger that charges via the USB-C PD port.

I think the USB-C PD port will replace most proprietary DC charging jacks in the future.

for 12v at this point in time it looks like the LinkOn 112.5w is the most your going to get.

Hi,

This is an old thread but In the end I ordered this:

Outtag 90W Slim Universal Laptop Charger 15V-20V Automatic Voltage Power Adapter Supply with UK Plug Cord for Asus HP Dell Toshiba IBM Lenovo Acer Samsung Sony Chromebook for Tablet and Smartphones: Amazon.co.uk: Computers & Accessories

it works like a dream and charges my laptop in an hour with no excess heat etc. I did contact the seller directly to double check it would work so I would advise this to make sure your laptop is compatible.

Hope this helps, I found it a total nightmare navigating watts and voltage lol!
