Not the smallest or most powerful option available, but...

Amazon has the available for $39.99. (Look for the green "Savings" heading and click redeem, or use promo code ANKER9125S to get that price).

This is only 65 watts, so whilst it has 3 USB ports (2xC, 1xA) it will only charge one device at what would normally be full speed. If you plug in 2 USB-C, it'll drop to 45 watts, which is still enough to charge most things (at least when idle), but will obviously be slower. The real benefit over most of their other devices is the 3 foot power cord, and the fact it's a "power strip" (if only with a single socket!)

I was trying to figure out how this negotiates charge rates. In the description I found this helpful nte:


Also, note that this works with power sources up to 240v (as do many similar power strips). Thanks for the suggestion -- I'm ordering one of these!

So this topic becomes even more timely with the introduction of iPhones with USB-C ports. As noted above I have already purchased several USB-C fast chargers so this will not result in much disruption though I may have to purchase a few more C<->C cords (though I believe the phones come with them).

Unfortunately I have no plans to purchase new Airpod Pros so I will still need to carry a C->lightning cord. And perhaps replace the A->lightning with an A->C cord for rental cars (see discussion above). But we are getting there...

Now what to do with all those soon-to-be-useless ipad charging cubes, A->lighting and C->lightning cords. Maybe a bulk sale on ebay or at the local flea market? Or perhaps I should bring them to Mexico on my next trip?

I received the Anker 615 referred to above. It's pretty nice, but when using the USB-C connectors to charge my MacBook laptop it only seems to get recognized as a high speed charge device after about a minute of negotiation. That is to say the power icon goes from to a minute after I plug the machine into this power supply. Plugging into any other power supply seems to get it recogni⚡ed almost instantly. My phone sees it as a fast charger instantly.

For everyone looking for cables both A-C and C-C. https://www.mycablemart.com/ I picked up a few 6ft C-C 100w PD certified cables for $6 each and a bunch of A-C 5gbps cables for $5 each. MyCableMart has always had incredibly high quality cables, I've never had one go bad on me.

Oh well, the Baseus Gan5 slim adapter looks to apparently be nothing special: while it does allow for the slimmer profile, its performance is apparently not great�

I have an Aukey 65 watt multiport charger.

Only 2 ports.

I was using for my MacBook Pro, using only the USB-C PD port and my MBP would disconnect and reconnect over and over again, that is the indicator showing that it's being charged.

Switched to a mini Anker charger, again 65W PD GAN with two ports, but using only the USB-C PD port.

I guess you get what you pay for. I think the Anker was $10-20 more.

OTOH, I have a Baseus multi port charger, 2 USB-C and 2 USB-A ports, 65 watts. Nice build quality. But when I connect my iPhone 15 Pro Max to one of the USB-C ports, it does the same thing, continually trying to maintain a charging connection. This occurs when I'm connect a third or fourth device, even something as light as my AirPod Pro case connected to one of the USB-A ports via a Lightning cable.

I can understand the chargers struggling to sustain a power connection to my 14-inch MBP, with M1 Pro processor, not even an M1 Max.

But charging an iPhone and AirPods Pro at the same time?

I'm wondering if going to a 100 or 120 watt multi port charger would make a difference. Those are larger so maybe better to get two smaller chargers instead.

Can�t do anything with the lightning cables except sell them (or keep them for old devices), but any USB-A chargers should still be usable with a USB-A to USB-C cable� just no USB-PD charging, probably limited to the previous charging limits.

(So, likely 5W, 10W or 12W, dependent on your charger�s limitations; new devices should all be able to use Apple�s 2.4A@5V spec / 12W capability.)

crackjack

The Baseus is having issues with the power renegotiation for whatever reason.

Could be an issue with the Baseus�s controller, could be an issue with one of your devices calling for too much power, could be your device is asking for too low a charge so the Baseus redirects the power only to find it has to again send power to the low-current device and thus renegotiates, could be the Baseus an issue with too much wattage being drawn on one circuit causing a safety shutdown and thus requiring the renegotiation.

Perhaps the higher wattage charger will help, or maybe the charger just needs a different profile for its power sharing/negotiation.

Of course, I am just throwing theories out - I am not an expert� and plus, there are too many unknowns here. Perhaps someone like chx would be able to give better advice.

I purchased a 4 pack of lightning to USB C adapters from Amazon. There are lots of rental cars with USB A only and no wireless Apple carplay which was my last rental at HPN

crackjack

Is there an authorised / quality adapter other than Apple�s $30 one?

As reasonably decent USB-A to USB-C (USB 2.0) cables (and $10 for USB 3.x), that is preferred�

der_saeufer

A new cable is definitely the best way to go, particularly as cheap as they are. You can also use a and any C-C cord you already have. That adapter is technically banned by the USB standard because you can do stupid things with it, but it's fine for using a C-C (or C-lightning) cable on a USB-A port. I've used one for CarPlay and Android Auto in rental cars for years.

crackjack

We may have discussed this before� but at the risk of repeating myself, personally I would stay away from such �dumb� adapters.

The one below is much better, with a pull up resistor and chip; I carry one in my travel kit, just in case.

(I do use use USB-A to USB-C cables with old USB-A chargers at home, particularly when fast charging is not needed. My Nitecore battery came with one, think I got others with external SSDs or HHD enclosures, though those would be 5Gbps+ capable.)

I have seen the same from other brands, but at least CC is a semi-known entity.

(I may have been wrong before, I believe the pull up resistor is the key to identifying the host end, while the chip enables 5Gbps data speeds.)

der_saeufer

"Dumb" adapters should have the resistor just like an A-C cable, to indicate to the PD device that it can't pull more than 5V/2A. When Android phones first started using USB-C, there were a lot of really sketchy A-C cables out there. Benson Leung at Google was testing them and reporting the dangerous ones, but that seems to have trailed off as C-C got more common.

The one you linked is also USB 3.0 capable, which the $3 adapter I use isn't. For the small extra price over a no-name adapter, I'd recommend it too. It's better than having to carry an extra cable just for the rental car.

crackjack

Yes, I only bought it after seeing Benson�s acknowledgement of it. Especially, he confirmed that it checks for and blocks unsafe connections between USB-A ports, e.g. will not allow Vbus voltage on the following:
Device-A < A-cable-C >Adapter> A-Device, or
Device-A <Adapter< C-cable-C >Adapter> A-Device

(Granted, people with a bit of an understanding on how USB works shouldn�t try something like that� but you can never account for the� let�s see what this does� factor. Better to have the smarts in there just in case.)
