Different types of chargers
2024-09-11
Chargers are an integral part of our everyday life, necessary to keep our electronic devices in full working order. From smartphones, through laptops, to tablets and smartwatches - the variety of chargers available on the market is huge.
Mains chargers
A wall charger is a device that plugs into a wall socket and charges an electronic device. This is a stationary charger intended for indoor use. Wall chargers come in all shapes and sizes. They can be used to charge a variety of devices, including smartphones, tablets, laptops and even electric cars.
Inductive chargers
An inductive charger is a device that enables wireless charging of electronic devices by using electromagnetic induction. Its main goal is to eliminate the need to use traditional cables and connectors, ensuring convenience and ease of use.
Car chargers
A car charger works on the same principles as a wall charger. The main difference is a different type of connector and the input current value.
The 12v charger is suitable for use in passenger cars. However, the 12-24v charger can be used in both passenger cars and trucks.

Explanation
Maximum power - limit mocy rozdzielony na wszystkie porty w ładowarce.Jeśli użytkownik podłączy w tym wypadku 3 urządzenia to moc rozdzieli się w następujący sposób:USB-C 1 + USB-C 2 + USB-A: 45W + 18WczyliUSB-C 1 + USB-C 2: 45W (na pojedynczym złączu osiągnie ~20W)USB-A: 18W Input current - prąd potrzebny do poprawnego działania ładowarki. Zakres napięć i częstotliwości może zmieniać się w zależności od wprowadzenia produktu na dany rynek.In the case of the Acefast A45 model we have: 100-240V / 50-60Hz / 1.5A, which indicates the universality of the charger. The range of voltages (V) and frequencies (Hz) will allow us to use it all over the world.
Output current - current received at a given connector to power devices, optionally with fast charging protocol.
Using the example, we can say that depending on the type of connector, we have different current parameters:USB-C 1: 65 W (PPS, PD, QC, AFC, FCP, SCP)USB-C 2: 65 W (PPS, PD, QC, AFC, FCP, SCP)USB-A: 22.5W (QC, AFC, FCP, SCP)
A single USB-C connector will support up to 65W of power in support of PPS, PD, QC, AFC, FCP, SCP fast charging standards. A single USB-A connector will support up to 22.5W of power in support of QC, AFC, FCP, SCP fast charging standards .
You should also remember that the protocols are activated with appropriate current parameters and compatibility with the device, which can be found in the Charging Standards section.
