Got a MBP with USB-C and I have had issues with cables going.

The original apple cable I assumed had got bent too many times as its not like magsafe.

So I bought another charger (amazon basics one) and it was fine. Another few weeks on and this morning it's done the same. Not charging for me.

I try it in my galaxy s phone and the charge flicks on and off as it would if disconnecting/reconnecting.

Next strange thing is if I remove the plug end in the charger it continues to so the same on/off behaviour.

Has anyone else had this with them?

Has the charger gone ? I had this before on an MBA...!

Must admit this is the last apple product I'm buying as I'm sick of it.

Was the Amazon Basics charger sufficiently powerful for the laptop? Apple chargers have a rating in watts - for example my MBP uses an 85W charger.

Running a charger with a lower rating than the computer needs won’t do the charger much good!

If you've damaged the cable it could have shorted out and damaged the PSU. Get a proper Apple cable and try that.

I've owned 3 Apple laptops since 2005, I've never had to replace a cable or power supply, Magsafe helps, so hopefully that will return. Same with 5 iPhones, never had to replace a cable.

Ahh, that's just the cable. So I assume you're still using the apple charger itself, so won't be that causing the problem.

You've been lucky here then.

Yes that's right, just using the cable with existing charger.

I'm going to buy another C cable thats the official cable and then that is my lot, i'll be moaning to Apple lol.

That cable you linked to is rated for 5V @ 3A. Watts = V x A so will deliver up to 15W. As mentioned your MBP is going to need way north of that, typically 50W - 90W dependent on model. Your charger and cable need to support that. If the charger and laptop exceed the cable rating you'll get the sort of side effects you've observed. If the cable and charger match but are lower than the laptop requirement it'll drain slowly over time as it's not enough to keep it charged and if the charger and cable exceed the requirement of the laptop then nothing adverse will happen.

The cable you got is basically designed for phones which require much less power draw. By getting an official apple replacement then I'm sure it'll be rated correctly, however third parties do make ones of sufficient spec. Here's one that's rated at 20V @ 5A = 100W https://www.amazon.co.uk/nonda-Charging-Braided-Co...

The spec on that says "power output up to 5V, 3 Amp" which is 15 Watts. I suspect a MBP charges at more than that, so you may have cooked the cable.

Thanks everyone this makes sense now.

What a joke, I've gone through 4 cables now thinking it was me bending them.

It's the charger that's gone here. I've tried the 100w cable and same behaviour.

Is it just hassle trying to save a few quid for a non apple one?

The problem with USB C cables is that they hugely vary in specification, not just data rate but also power and it is basically impossible to know at a glance if the cable is right for your use case without poring over the specifications. This is because the connectors at both ends look the same regardless of cable spec! The USB design group have come in for a lot of criticism over this as consumers are struggling.

Personally I would not skimp on getting a knockoff charger. Lots of potential to blow up your £xxxx laptop or your house.

Ordered the real one doing more research.

Conversely we've had Mac laptops in the house for 20yrs and the chargers have been by far the worst aspect.

Very poor strain relief at all ends of the cables.

USBC is a poor connector IMO too. No positive location in the socket. That bit's not an Apple issue - I'm having issues on a Lenovo too where the connection is getting looser over time.

I suspect part of my issue is using a laptop on my lap with cables plugged in. But I dou t I'm alone smile

I'm just careful. Magsafe helps, haven't had a USB-C yet, hopefully magsafe will return in the next laptops.

I have learnt from bitter experience to only use Apple chargers and cables for my Apple products. You can get some really odd behaviour from non-Apple chargers and cables which can make you think you're going mad...

New charger arrived yesterday.

I've actually put the first cable on that started the whole "must be a bent/dodgy cable" theory....

If anyones interested in some USB-C cables im your man lol

Before jumping to diagnosing dodgy cables, BTW, try a quick spritz of an air duster into the charger socket to dislodge the fluff that collects inside as it often solves the non-/intermittent charging problem, both on the USB C and old MagSafe ones.

Would that include the Charger end?
