Are 2A available per port? I want to charge 1 devices at the same time like an iPhone 7 Plus and an iPad Air. Is this possible?
Yes, with the tizi Tankstelle (2 Ports), you can use a maximum of 2.4A per port. There is a total of 4A available per tizi Tankstelle (2 Ports). For instance: an iPhone can charge with 1.6A, while simultaneously charging an iPad with 2.4A, totaling in 4A. Or you can charge both an iPhone with 2A and an iPad with 2A concurrently, totaling in 4A.
I have a Bose Soundlink Mini II and this beeps when charging and does not charge. What can I do?
Please use the shortest possible cable to recharge the Bose Soundlink Mini II. It is due to the copper content of the cable. Unfortunately, no-name cables will hardly contain more copper.
Terminals that require more than 1,000mA are sensitive to it. With cables, always buy branded products. The market is unfortunately flooded with cheap goods.

Can I also use my tizi products in the USA with 110V?
Yes, your tizi gadgets also work in the USA. All you need is a plug in adapter! The power supply in your tizi device works with both 220V and 110V.
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:

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.
