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.

We recommend the use of tizi flip ULTRA cables in combination with tizi products:

Do tizi USB-C chargers work with any USB-C to Lightning cable?

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.

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.

tizi power supplies are specially tailored to Apple devices, "speak" correctly with the charging controllers installed by Apple and are always able to supply the battery of an iPhone / iPad with the requested current. This means, when using a tizi device, the battery of an iPhone / iPad is never overloaded or even broken.

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.
