USB Multi Charger for all your devices?

What Peter Says is correct. Cigarette sockets rely on the plug contact to be held in place by a spring and all sorts of problems with that occurr down the track. With the Merit connector, the plug contact slides into a proper socket. This makes a much better connection and tends to be self-cleaning by the action of the male contact sliding into the socket.

A little known fact is that 5V power supplied by the original USB connectors is only specified for use for low powered devices. Phones that can charge quickly and tablets are powered by voltages of up to 48V. This can not be supplied directly from a 12V cigarette socket. It requires some sort of inverter in the line. SCUBADOO has given a link to devices that do that, but I would not rely on these for long time use, as they plug into Cigarette lighter sockets. If you look at this link Power you will get a bit of a grasp on the subject of USB power.

If you can not find devices that can be connected directly to your battery through reliable connectors, then make up your own panels or boxes and cable them directly to the battery (and don't forget the fuse near the battery to protect the devices wiring.)

.
To add to Peter’s wisdoms…. Some accessories such as navigation aids often come with a cigar plug and integral power module which prevents changing from the cigar connection. So if you must use them then the plug tightness can often be improved by judicious bending of the side contacts out a little or by adding a turn or two of insulation tape to increase the plug diameter as has been suggested earlier.
The cigar plug is the descendant of the long gone auto cigarette lighters but we unfortunately seem to be stuck with it as it’s cheap and easy.

If you buy decent after market lighter sockets then you're less likely to have issues I also used twin core 6mm wire on them. I ran a fridge off a lighter socket for quite few yrs in 3 different vehicles with sockets I had mounted in the rear. Even done a 3 month trip from Perth to Mackay 19yrs ago with the fridge in a lighter socket in a 4wd wagon the whole time with some off road trips included. It also helps if the fridge comes with a decent plug like Evakool did. I have been using a gps for maybe 15yrs or more never had the plug come loose.
Same with merit sockets you get good and not so good one's.
I haven't had any problems with Narva products including their usb's.
In the cabin of my current BT50 I have permanent power to aftermarket sockets 2 are lighter, 1 x dual usb and an Anderson plug.
Also my last 3 starter batteries I have used dual purpose 105 ah Supercharge All-rounder so no problem charging items while the car is off or running a fridge for 1 or 2 nights.

Same here mate. I have the original cig skt in the Pajero and run my Tablet and phones with no problems and all charge up.

Well we actually do this - but only for charging my DSLR camera battery in its 240v charger occasionally (power board under passenger seat) as I lost my second battery and murphy always catches me out. Just remember to turn off your inverter!!

Garry L in a word NO as it relies on the cigarette plug and as I said most cigarette plugs supplied on vehicles are not designed for anything more than 20 seconds use to heat a cigarette lighter.
The positive pin on a cigarette lighter plug rarely makes any more than a few square mm of contact and so are prone to heating if higher currents are required for any length of time.

Peter

I don't have or use one but numerous friends do with similar products without issue.

They get away with it for a while but it is not a long term solution.

Agree with the others, a lot of cig outlets in cars these days are only rated for 10A or less, if you keep the draw below that you might be ok but you would be better off installing wired in chargers like these:

For things like laptops then use a marine cig locking outlet or a merit type though I have still had issues with those and larger laptop chargers. You might find a small wired in inverter is the better option and use the AC power pack.

Garry L - quote "Peter - I don't have or use one but numerous friends do with similar products without issue."

I see a possible answer to why your friends are having no issue with the physical connections of their devices. If you run your cursor over the stem of the connector, you will see the info in the attached .JPG file. It states on there the capabilities of the USB ports. Whilst the advert claims there is QC3.0 capability, that capability is very limited. You will note its maximum output is 12V @ 1.8A. It is quite common for these cigarette connection devices to not deliver their advertised capability. If they can not deliver what they promise, they can not stress the electrical connection.

In addition, that 12V, 1.8A output is insufficient for the OP's requirement. It will take him all day to charge his high power devices. If he wishes to charge them in a timely manner, he requires a quality device, hardwired in his vehicle.

Yes I am also guilty of using cigarette lighter devices but when I do i have to put up with them dropping out of the socket over rough roads and being dislodged when someone is rearranging things. I also only use them for flee-power devices.

Peter

I wasn't looking for an argument or a lecture - I just gave the OP an option that might suit his situation.

I have a factory usb port in both my 4wd's and they are just used for my phone and on the odd occasion a tablet. One lot of friends who travel Australia full time have been using a 4 port charger similar to the link one for 6 years and they said it's never missed a beat, fallen out, set their car on fire or exploded !

I don't use cigarette sockets for any 12 volt application as I know there downfalls.


Have a good Christmas and stay safe !

That's exactly the right solution. USB C PD.

It can power up to 100W from cig adapters, or OE style switch outlets and can power USB mini, micro, apple, wireless, laptops and even DC outputs to 28V ( if you get the right one)

All phones and new devices have to be USB C for the EU so it has a massive eco system. Even apple was forced to use it

Cheap, powerful, wide support, and easy.

It's the best choice by far these days. I'm surprised more people didn't suggest it.
