Chapter in this post:
The boys and girls at equinux kindly sent me a special kind of USB car charger. The name is far too normal for equinux standards: "tizi Turbocharger 2x ULTRA" - I would have expected rather "tizi Bad Finger" or something, but "Turbocharger 2x ULTRA" also fits relatively well due to the performance data. Now let's get into the test ...
There is not much to say about the optics and design of the tizi turbocharger 2x ULTRA. So far I have really liked all the products in the tizi range. They are neatly made, look good and are functional. The red top of the turbocharger is an eye-catcher in the car - even if, unfortunately, the rest of the car looks all the scruffy to me if you place such design objects as the tizi turbocharger in the interior. : D
You can do it as you like, but I trust technical devices that are "made in Germany" somehow more than all the China stuff that you usually find on Amazon. In no way do I want to attack well-known manufacturers such as Anker, Aukey or Rampow, who without question offer high-quality equipment, but there are so many non-name products from the Far East on Amazon that are unfortunately big scrap that I prefer to recommend branded goods that last, what it promises. When it comes to live accessories, you shouldn't take any unnecessary risks.
Equinux itself states the following points that distinguish the company and its products from the competition:
I can understand the points, because I am often offered products from the Far East for testing. I often take these tests out of personal interest. It is not uncommon for these devices to be defective after a few weeks and the company in question can no longer be found. An exchange is then difficult for real customers and it is extremely annoying when accessories that you rely on fail at some point when you count on them.
But this is not meant to be an advertising contribution for equinux. I would just like to explain the advantages that you have when you buy your equipment from well-known companies.
Inset - More interesting posts from the blog:
I have the tizi turbo charger 2x ULTRA with me on a 240V to 12V voltage converter (. the test report) so that I didn't have to mess around in the car all the time. The measurement results should, however, correspond to those that one would have when operating on a "cigarette lighter socket" in a car. So don't be surprised if you can't see the interior of the car in the photos. : D
Since I bought the USB-C to Lightning charging cable from Apple at some point, now was the right time to use it in practice. Since the tizi turbocharger has a USB-C output with USB Power Delivery for fast charging, you can charge your iPhone 8/8 Plus or iPhone X faster than a normal USB port. How nice in another post A power source with USB-C PD and a USB-C to Lightning cable are required for this.
So I have my iPhone X connected and with it my USB-C multimeter Current and voltage measured. The result: the iPhone is charged with 9,4 volts and one ampere via the USB-C port. What matters to the battery, says parallel to it the CoconutBattery appwhich receives information about the charge status of the internal iPhone battery directly from iOS. The specification of Coconut Battery is: 7,68 watts.
In comparison: Charging via the USB-A port results in approx. 6,1 watts and the battery still receives 3,3 watts via a Qi charger. You can see that you get your iPhone about 25% faster than with a normal USB-A charging port. Disadvantage: You also have to have the right USB-C PD to Lightning cable with you. If you don't have one, you will find it . an inexpensive and functional alternative to the expensive Apple cable.
By the way: As much as Apple users enjoy using adapters: When you clamp a USB-C to USB-A adapter in front of a normal Lightning cable and hope that you have made a cable, so to speak, that USB power Delivery for Fast Charge supported, then you will be disappointed. With such adapters, the iPhone 8 or X unfortunately only charges with the usual 5 volts.
I did two tests with the MacBook: On the one hand, I plugged it into the standard USB port with a USB-A to USB-C cable and, on the other hand, via the USB-C port. With the USB-A port, the MacBook is of course only supplied with the usual 5 volts that a USB-A port provides. The tizi turbocharger brings a whopping 2,3 amps on the way, so that we provide around 4,69 watts of power at a measured 2,3 volts and 11 amps. That is even enough to charge the MacBook while it is running, but of course it is not fast.
The MacBook charges significantly faster with a USB-C cable that supports USB-C PD. I used the original Apple cable and came up with 20,7 volts and 1,41 amps, which is about 29,2 watts. The original USB-C Apple power supply unit for the MacBook happens to have 29 watts, so that we can charge our MacBook here in the car without any loss of speed - great!
Since the maximum voltage on the packaging of the tizi turbocharger 2x ULTRA is only given as 15 volts, I once contacted Equinux with my measurement results and received the following information immediately:
You are right in your observation. The device can also deliver a voltage of 20V, but this is quite exotic with a power rule of maximum 30W. Apple controls the charging logic via software, everything can change again with the next macOS update. We have therefore deliberately refrained from naming it.
Thanks for the quick and competent answer. That's what I call good support - "made in Germany". ;-)
The 15-inch MacBook Pro has the highest power consumption that Apple laptops offer. The included power adapter has 86 watts for this reason. Of course, the performance of the tizi car charger doesn't match that, but I still wanted to try out how the MacBook Pro works on the car charger.
I installed CoconutBattery on the MacBook Pro and can almost directly access the current charge status of the battery. For comparison, I took a screenshot with the MacBook Pro on the tizi turbo charger 2x ULTRA. You can see that the battery cannot be charged with the 30 watts during operation - but at least the battery is only discharged with about 3 watts instead of the 25 watts that I usually have when blogging. If I have the MacBook Pro with Geekbench torment, I even manage to consume 45 watts for a short time, but that is by no means my everyday consumption.
This means that even if I cannot charge the MacBook Pro with the tizi turbocharger while using it, I can increase the battery life many times over. If you close the MacBook Pro and go to sleep, you can even charge the battery - slower than with the original power supply, which delivers 86 watts, but at least.
I would like to briefly comment on two things that struck me. On the one hand, the voltages on the packaging of the tizi turbocharger are never mentioned as 20 volts, which it actually offers via USB Power Delivery. There are only values between 5 and 15 volts. The MacBooks use a full 20 volts, which the turbocharger delivers for a long time without any problems. I charged the MacBook with it for several hours and there was no interruption due to overheating or overvoltage. If equinux does not actively advertise this as a product feature, is explained in the answer from the support above in the article.
The second thing that struck me: On Amazon there is a product text that says the following:
Charge your MacBook or MacBook 13 ”for the first time in the car via USB-C - just as quickly as with the Apple 60W adapter at home! Perfect for private and business trips.
That is not entirely correct, because the tizi turbo charger 2x ULTRA only offers 30 watts. It offers just as much power as the Apple power supply for the MacBook, but not the 60 watts that the power supply for the 13 inch MacBook Pro has. So keep in mind: 30 watt output power via USB-C PD - nothing more. I pointed out this incorrect formulation to equinux and they confirmed to me that this will be corrected soon.
I am enthusiastic about the tizi car charger. The form factor is great and it sits securely in the car socket. The USB-A and USB-C sockets also offer a secure hold for the charging cable plugs. The performance data that I have measured is very good for my use.
I have my MacBook in the car - not often, but every now and then - and if I have to work with it for a long time, there is no avoiding an additional charge. So far I had a voltage converter for this, which brought 12 volts to 240 volts, so that I could plug in the power supply, which then turned the 240 volts into 20 volts. It's easy to imagine how inefficient the whole thing is.
With the tizi charging adapter, I can now charge all devices - from iPhones to iPads to MacBook Pros - in the car. For me, the part is the proverbial "egg-laying woolly milk pig" for on the go and I don't want to miss it anymore.
The low standby consumption is also important to me, as the power in the cigarette lighter in my VW bus is not automatically switched off when the car's ignition key is removed. Thanks to the low standby consumption, you don't have to worry that the car battery will be drained by the adapter in the long run.
If you want to buy this adapter, you will find it via this link on Amazon. Or you go through this product box:
Since equinux made this product available to me for a test free of charge, I would like to mention my comment on such product tests:
