With universal chargers, you can recharge your smartphone, laptop or tablet quickly and safely. TECHBOOK compared 5 high-performance products.

Reading the news on your smartphone, making phone calls and then scrolling through social media accounts – this always drains the battery. Of course, to recharge it, you need a suitable charger. On the one hand, this can be done with the power supply unit that may be supplied, or with a universal model. The latter is particularly practical, because major manufacturers such as Apple and Samsung usually no longer include chargers when buying a smartphone. The most powerful universal chargers also have different connections, so that you can charge cell phones, speakers, tablets, etc. And even when traveling you only have to take one charger with you for several devices. TECHBOOK has taken a closer look at 5 powerful USB universal chargers for the socket and presents the best models.

Which chargers for smartphones, laptops and Co. are there?

When buying a mobile phone or laptop, a charger is usually no longer included in the scope of delivery. And even if it does – at some point it will be lost, broken or a second device will be needed. At that point at the latest, universal chargers are a good way of continuing to charge your devices conveniently.

These are available in different versions, including a compact USB charger for the socket, for the car or the bicycle, as a wireless Qi charger or as a larger table model with many different connections for several devices.

Qi charger: Inductive charging

Just charge your smartphone? This can be done with a USB charger that is connected to a power or wirelessly via a Qi charging station. Qi charging stations are particularly convenient because you only have to place your smartphone on them. An extra charging cable that is plugged into the phone is not necessary here. However, the most obvious disadvantage of these devices is that the charging time often takes a long time.

In addition, such Qi chargers can only be used for smartphones and the batteries of several devices cannot be charged at the same time. In addition, the smartphone can only be used to a limited extent during the charging process.

USB chargers: Extra fast charging

A USB charger is characterized by the fact that it often has different ports on which several devices can be charged at the same time. Such chargers are called multi chargers.; However, there are also models with only one USB port. In addition to being able to charge different devices at the same time with just one plug, the USB chargers for the socket offer even more advantages.

Above all, the charging time is significantly shorter compared to Qi chargers. With a corresponding purchase, several devices can be charged at the same time, and in principle all electronic devices are compatible. If you charge via USB, you can also connect your cell phone to your car, for example. In comparison, these chargers are also quite cheap.

What should you pay attention to when buying a charger?

If you want to buy a USB charger for your cell phone or tablet, you not only have to think about how many USB ports are required, but also with which devices the power adapter should be compatible. For some devices, certain requirements must be met so that they even fit together with the charger. The specifications volt, watt and ampere give an indication of this, which will be briefly discussed here.

Amp: The physical unit ampere indicates the maximum current that can flow through a power supply unit. USB chargers with a high amperage rating charge electrical devices faster than those with a lower amperage rating.

Volt: Volt is the unit of measurement for the electrical voltage that is on a power such as the wall outlet. This shows how strong the current is. With a USB charger, the voltage is always 5 volts, even if the socket actually supplies 230 volts.

Watt: The wattage describes how much electricity is converted into energy by a device in a certain time.

The biggest differences are mainly in the number of available USB ports. The more of them there are, the more devices can be charged in parallel. There are hardly any differences in the equipment with protective functions. Most chargers now offer protection against overheating, overcharging and overvoltage. Whether the charger is a USB 2.0, 3.0 or 1.0 also plays a role in the purchase. The number indicates the transfer rate in megabits per second.

Also interesting: That’s why you should always unplug the charger from the socket
