Power supplies can have errors or problems at different levels. What do tizi chargers do better than 'standard' or cheap power supplies? 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. 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. Initially maybe with 500mA, then 1A, then with 2.4A etc. Our tizi charging devices (Tankstelle, Tankstation, Turbolader, Kraftprotz, etc.) respond correctly and the iPhone / iPad starts to charge. 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. How can a tizi charger always provide iPhone / iPads with maximum fast performance? In no case will a tizi device 'push' a certain amount of power into an iPhone/iPad or smartphone!

The iPhone/iPad or smartphone actively decides how much current to use and which energy gets requested from the charger. Here, in the worst case scenario, the battery can be destroyed by charging it wrong.Īpple and all modern smartphone manufacturers use active charging control mechanisms with in their devices. In this scenario, the charger is actively doing the charging and the battery is 'dumb' and gets charged. Where does this theory come from? It might originate from charging standard AA or AAA household batteries. Some people may believe this and there are various myths on the internet about this. IPhones and iPads are *not* 'dumb' batteries that get connected to a charger.
