I own a MacBook Air that is charged with USB-C and only with 30 watts. Can I also use a tizi USB-C power adapter that provides more watts?
The answer is clear: yes. USB-C devices use the PD, Power Delivery standard for charging. Here, the device, such as the MacBook Air, asks the tizi power adapter how many watts the tizi power adapter could provide at most. Then the charging controller starts in the MacBook Air and actively draws exactly the power it needs to charge. If, for example, only 30 watts are needed, the MacBook Air only draws 30 watts. A more powerful tizi power adapter can therefore never harm a USB-C device. The device itself decides on the power consumption.
Is USB-C charging only possible with iPhone 8/X/Xs/Xr/11/11 Pro/SE/12/12 Pro/13/13 Pro or also with other, older iPhones?
Older iPhones charge on tizi USB-C power supplies (tizi Tankstation USB-C, tizi Tankstelle USB-C and Turbolader ULTRA) both on the USB-A port and on the USB-C port. When using the USB-C port, the tizi flip ULTRA or Apple USB-C to Lightning cable is absolutely necessary. This cable is only available from certified manufacturers such as tizi or from Apple itself, as they install Apple's own circuits there. Other providers on Amazon etc. often offer fakes that cannot be used.
Do tizi USB-C chargers work with any USB-C to Lightning cable?
We recommend the use of tizi flip ULTRA cables in combination with tizi products:

Please pay attention to only use Apple Mfi certified cables. There are regular problems with uncertified cables. How does it affect your devices? Your devices will not charge, or maybe only charge a little bit. In addition, Apple can switch with any iOS update, which can potentially make not licensed cables inactive. Try to refrain from purchasing uncertified USB-C to lightning cables from unauthorized international sellers.
I have a USB-C to lightning cable and it does not charge.
Please check if your cable is authentic. USB-C to Lightning cables must be Apple Mfi certified. There are regular problems with uncertified cables. The reason for this is that both connectors include proprietary chips. Unfortunately a lot of these "fake Chinese cables" are offered on eBay and Amazon.

My iPhone 13 Pro Max, 13 Pro, 13, 12 Pro Max, 12 Pro, 12, 11 Pro Max, 11 Pro, 11, SE, X, XS, XS, Xr Max charges very quickly up to 80% and then slowly. Why?
All iPhones with fast charging (Power Delivery with tizi flip ULTRA or Apple Lightning to USB-C cable) charge very quickly up to 80%. From around 80%, the iPhone's operating system generally reduces the charging speed. How much this reduction is depends on the device's operating temperature. The iPhone further reduces the charging function if it generates a lot of heat.
A cold environment or targeted cooling of the iPhone (e.g. removing it from the case, placing it on a cold surface or even using cooling packs) then helps to continue fast charging even from 80%.
Does Apple MagSafe work with tizi products?
tizi products work with the Apple MagSafe Qi charger. It is important to use a tizi charger with a USB-C PD output.
Further details on MagSafe compatibility can be found on our MagSafe page.
Note: There is a MagSafe connector from Apple for older MacBooks. This connector does not support USB-C PD charging and is therefore not compatible with tizi products.

Charging with the tizi Schlitzohr
The tizi Schlitzohr is not suitable for quick charging via USB-C Power Delivery, as it works using a USB-A connector. It is possible to charge USB-C devices with the tizi Schlitzohr, but in this case, USB Standard protocol is used and the device will charge at a maximum of around 12W.
Why don't tizi USB-C chargers support Android Qualcomm QuickCharge / QC2.0 / 3.0?
Compatibility with Qualcomm QuickCharge / QC would reduce the performance when charging Apple iPads. We strongly advise Apple users to stay away from USB-C chargers with QC standard. In some cases, the QC protocol overrides communication with Apple iPads, which means that the best charging performance will not be achieved.
With the tizi USB-C power delivery chargers, we have deliberately decided not to integrate QC. The power supply is designed to be fully optimized for Apple users.
Is fast charging with tizi charging devices harmful to my smartphone battery? Can this damage the battery in my iPhone/iPad?
iPhones and iPads are *not* "dumb" batteries that get connected to a charger. Some people may believe this and there are various myths on the internet about this. Where does this theory come from? It might originate from charging standard AA or AAA household batteries. In this scenario, the charger is actively doing the charging and the battery is "dumb" and gets charged. Here, in the worst case scenario, the battery can be destroyed by charging it wrong.
Apple and all modern smartphone manufacturers use active charging control mechanisms with in their devices. The iPhone/iPad or smartphone actively decides how much current to use and which energy gets requested from the charger. In no case will a tizi device "push" a certain amount of power into an iPhone/iPad or smartphone!
How can a tizi charger always provide iPhone / iPads with maximum fast performance?
The best way to imagine this is as follows: When plugged in, an iPhone / iPad uses a communication protocol to ask the power supply about the maximum power that can be drawn. Our tizi charging devices (Tankstelle, Tankstation, Turbolader, Kraftprotz, etc.) respond correctly and the iPhone / iPad starts to charge. Initially maybe with 500mA, then 1A, then with 2.4A etc. Depending on the model and the current charge level, but also on the battery temperature of the iPhone / iPad, the Apple charge controller decides actively and independently how much power should be drawn.
Thanks to the above-mentioned exchange about the maximum power, the Apple charging controller can be sure that it will get this power at any time over the charging period.
What do tizi chargers do better than "standard" or cheap power supplies?
Power supplies can have errors or problems at different levels. Here are two classic examples:
- With cheaper power adapters, the communication protocol is often missing, meaning the adapter and the iPhone / iPad are unable to communicate properly. If an iPhone / iPad gets a strange result from the power supply when the performance data is exchanged (e.g. the protocols of both devices do not understand each other), then an iPhone only charges with a maximum of 500mA, which is very very slow. In this case, the iPad will show the "Not charging" message. The iPhone / iPad does this in order to prevent the power supply from becoming overloaded.
- Another problem is possible overload - leading to a fire hazard. For example, this could occur if the cheap power supply tells the iPhone / iPad that it is able to charge up to 2.4A. If an iPad then requests this current during the charging process, the power supply will become overloaded. In the best case, it will simply turn off. However, it could also overheat and catch fire.

I would like to use a tizi USB-C PD product for fast charging my iPhone/iPad. What should I be aware of?
For fast charging you need a tizi or Apple Lightning to USB-C cable. Buy this cable from a brand manufacturer like tizi. No-name suppliers often times offer fake china cables which do not work!
When charging, plug the cable into the Lightning jack on your iPhone / iPad and then into the USB-C jack on your tizi device.

Do tizi chargers with a USB-C connection support fast charging of the iPad Pro (2018)?
Yes, tizi charging products with USB-C ports, such as the Tankstelle USB-C, the charging stations with USB-C or the tizi Turbo Charger ULTRA support fast charging via Power Delivery on the iPad Pro (2018).
The iPad Pro (2018) has a USB-C port. The tizi flip USB-C cable or the Apple USB-C cable are recommended as connection cables. The use of cheap China cables is strongly discouraged. Cheap cables can only be produced by saving on the copper content in the cable. The copper content of these cheap cables is usually too low and can lead to heating or fire of the cable.
Which version of Power Delivery (PD) does my tizi product use?
For charging, we use version PD 2.0 in the USB-C port. In general, versions 2.0 and 3.0 of Power Delivery are congruent in the charging power area.
Version 3.0 only brings additional information and functions, such as reporting overtemperature or voltage drops, etc.
I am receiving the warning message "Accessories may not be supported", is my tizi device defective?
According to our experience, this error when used in combination with a tizi device indicates connection problems with the cable used.
Please check the Lightning cable for the following defects:
- The cable is broken, bent, or "frayed"
- The contacts of the Lightning connector are partially darkened
