More and more smartphones are delivered without a charger.
As a customer, you have the choice: Either you continue to use your old charger or you invest in a new power supply unit.
The advantages of a new purchase: You can opt directly for a device that can be quickly charged.
As inconspicuous as chargers are, the technology inside is just as funky.
For a long time now it is not just about plugging in your cell phone and being good.
There are now as many fast charging protocols on the market as there are charging standards.
Keeping an overview is not that easy.
Quick Charge
here
,
Power Delivery there
: Somehow you still have in mind that your own smartphone is at least theoretically able to recharge the battery quickly.
This not only requires a fast-charging smartphone, but also a fast-charging charger and of course the corresponding cable.
If you want to buy a charger, you have to pay attention to many
different points
.
If you want to charge not only your smartphone but also your laptop with it, you also have to make sure that the charger of your choice has at least 30 watts of power.
In the test by AllesBeste, the
chargers were tested with different smartphones
, from Apple to Asus to Huawei.
A power-hungry laptop was also available for the more powerful devices.
The respective charging capacities were determined with the aid of a USB multimeter.
To test the temperature development under full load, an electronic load was attached to each USB port of the charger and operated for one hour.
The temperature was then determined using a laser thermometer.

USB chargers in the test
The test portal AllesBeste took a close look at 26 models
.
The winner of the test for chargers with a USB port was the
Anker Powerport III Nano
.
With an output of 20 watts, it is right at the top when it comes to performance.
Because it is also compatible with a large number of charging standards (Power Delivery, Quick Charge, etc.), it is also a good all-rounder that can cope with pretty much any smartphone.
The only disadvantage: the extremely compact anchor tends to get hot under full load.
With a temperature of 63 degrees, the charger is still within a tolerable, because it is harmless, range.
