fast charging USB cables?

JustAnotherSaver

For what I'm wanting to do I'm ideally needing right angled cables. Both ends don't necessarily have to be right angled but the one that plugs in to the phone certainly does.

I bought this cable 2mtrs in length and connected it to this mains charger. The result was the phone flashed up that it was 'fast charging' - result.

I then plugged the same USB cable in to this 12v charger and it only said charging. The difference was 45min for the mains charger, 60min for this 12v charger.

So then your response is "well that's the difference between that 12v charger and that mains charger".

Or "that's what happens when you get a 2mtr cable. You need 1mtr".

No.

Because then I tried the 2mtr version of this cable in the 12v charger above and it displayed 'fast charging' on the phone and back down to 45mins.

What I'm looking to achieve is to have a cable 'hard wired' behind the dash of the car on the switched live circuit with the end popping out where the phone will be mounted in the bottom right of the windscreen. 

The idea is 12v female socket wired in, 12v male charger as above connected in to the 12v female socket & a cable ran from this poking out where it needs to poke out.

"But fast charging kills phones".

I didn't say the phone will be on charge 24/7. You can set the phone to not fast charge via wired charging but I would like the option of it.

For the most part it wont even be charging the phone. It'll be primarily for 1) those times when you're just in a situation where the phones battery is damn near dead, you're in the car & you need to get juice in it. and 2) when you're going somewhere you have no clue about & you're wanting to run Google Maps/Waze.

So for the times it's going to get used, I really don't believe it's "going to kill the battery".

"So what's the point if it's barely going to get used" .... because for the time that it does get used, I'll be glad it's there. Plus I hate wires on show.

Ok if i've understood this right then the cable I bought, the UGreen one, is marked as 18w 3A.

The eBay link says 100w 5A.

Which to me not knowing electrics & the like would explain why the eBay one charges quicker than the Ugreen one.

Though what it doesn't explain is why the Ugreen one, slower in the 12v car charger, was giving out fast charge in the mains charger. If the cable isn't suitable for charging speeds, surely it isn't suitable regardless of what it's plugged in to??

Your post is a little confusing. Nothing to do with the cable. Charging from the mains will always be quicker than charging in your car.

It's probably the resistance of the cable(s) ... the Ugreen one is probably a little higher resistance than the other one, so it worked for fast charge in a mains charger (which can give a higher output) but couldn't quite cope in the 12V charger. The other cable is probably lower resistance so can fast charge via either source.

Its all a lot more complicated than you'd think

The ugreen is type a which goes in the 12W port the other is type c which fits in the 18W port perhaps this is the answer to your conundrum.

You'll have to explain to me what part of it is confusing & then I can try explain better. It's my question so it's pretty clear to me but then that's no good - it needs to be clear to you guys.

You say it's "nothing" to do with the cable. What I know about electrics you can write on a tenth of a postage stamp so what I say next isn't me challenging you saying you're wrong, it's just saying what (rightly/wrongly) my mind grasps....

If it was nothing to do with the cable (and therefore only the charger itself since that's the only variable other than the cable) then the mains charger should give out fast charging for both cables while the 12v charger should give out 'slow' charging for both cables.

Where clearly that wasn't the case.

The UGreen one was fast on the mains but slow on the 12v.

The other one was fast on both.

If what I'm looking to achieve is what is confusing to you then it's basically this ...

I want a hardwired charging setup in the car as I don't like wires snaking over the dash. Right now I have to plug in to the 12v socket, trail the cable up over the dash or behind the steering wheel, across in to the bottom right corner of the windscreen. I don't like it.

So my thought is to have a fast charging setup behind the dash so that whenever I want/need to charge the phone, it just goes in its cradle and I simply connect the USB cable (which will come out of the dash somewhere by the drivers door or possibly an air vent & then route upwards).

I could use the cable in the ebay link I gave because that provides fast charging on the 12v charger as I showed - but it'd be better if I could use an angled connector like the UGreen one.

The problem is as I tested out, the UGreen one doesn't provide fast charging via the 12v socket.

So in my mind, although you say otherwise, there has to be something about that UGreen cable that prevents it fast charging.

I'm not tied to any brand. I don't particularly care for brand. I just want an angled charger cable that provides fast charge.

It's a possibility I guess. That's another variation.

So what I need is a USB-C to USB-C with at least one end being angled and then seeing if the same happens or not.

Its nothing to do with the cable.

USB-C will deliver fast charging, USB-A in general won't. You need a USB-C to USB-C cable.

If you look at the Anker car charger its got two ports, one labelled PD with an oval USB-C port. PD is Power Delivery which is fast charging.
The other port labelled iQ is USB-A and won't be fast charging.

But it's not as simple as that ... my phone will fast charge from a capable mains adapter which has a USB-A socket. (Not the one that came with my phone - I think it's the one from my Fire tablet). So what matters is not just the capability of the device providing the charge, but also the cable being able to support it. It seems the 12V charger the OP is using will provide a fast charge for his phone, provided the right cable is used.

@JustAnotherSaver: have you considered a cable/plugs arrangement which uses magnetism to hold the plug onto the phone? (Random example to show what I mean - I use a different type and it supports fast charge from a mains adapter - not checked vs charging in the car).

JustAnotherSaver

Ah the magnetic cables. Tried them in the past and they weren't so great (speed). Though to be fair I possibly bought a cheap crappy one.

Still, magnetic or otherwise doesn't alter the situation - it needs to be an angled fast charge setup.

I'll return the cable I bought & go with what jon81uk just said with a double usb-c setup and see if that ticks the box.
