Wireless Charger in the test: what is important when buying

Many modern smartphones can be charged without cables. For this you need an inductive charging station according to the Qi standard. Qi chargers are already at prices around the Having euros can also be significantly more expensive. CHIP does the test and compares numerous models with each other. Our test winner is already for around 40 Euro available, while the tail light is also one of the most expensive devices on our leaderboard. What you should pay attention to when buying wireless chargers, we reveal in the video.

Qi chargers 2020: Overview of charging stations

Inductive charging stations differ not only in their design. Some of the models we tested have different additional features and also deliver different results in their main task – wireless charging of a cell phone. Even with identical manufacturer information on charging performance, there are sometimes several hours between the shortest and the longest charging time of the same smartphone. In addition, depending on the smartphone used, there may be relevant differences in charging time. So is the Samsung Galaxy Note we use 10 in the fastest case fully recharged in under two and a half hours, Apple's iPhone 11 Pro needs on the same charger despite the smaller battery but almost twice as long. On the other hand there are chargers that the iPhone 11 Charge faster than the Galaxy Note 10.

Furthermore, some Qi chargers score with special additional features, which are not a must but a nice nice-to-have. This is how the cell phone can be connected to a monitor or TV via a charger, for example via HDMI and USB cables. Another charger is also a backup station with integrated memory. When you hang up your cell phone, the device can be used to wirelessly secure your photos and contacts, among other things.

In the following table you will find a selection from our ranking. The complete test field with all tested products and their respective results can be found in our wireless charger best list . Below in this article we present the products from the table in more detail.

    Stand Up Inductive Charging Base Black

    Our test winner is particularly successful when loading our Android test device Good. For iPhone 11 Pro, however, it showed weaknesses. Still a very good wireless charger at a fair price.

Benefits
Android phone loads very quickly
Full Scope of delivery
No power consumption in standby
Disadvantage
Long charging time of our Apple test device
No dual-charge functionality
position not manually adjustable

The Cellularline wireless stand was able to compete with the others Enforce and manage charging stations t our best list – even if only slightly: Thanks to better efficiency, it leaves the competition from Terratec and Co. behind and wins the overall grade 1.3 (“very good”). Particularly noteworthy is the very good performance: Even if the charging time of the iPhone 11 Pro with more than four hours is no brilliant performance, the charger loads the Galaxy Note 10 in just 2: 01 hours fully – the best value in the test field.

In terms of efficiency, the Cellulaline Wireless Stand shines above all with a power consumption of 0.0 watts when the device is in standby. In other words: If there is no smartphone on the charging station, no electricity is used – this is not the case for all models. And the Charger can also score points: A modern USB Type-C connection, power supply and power cable in the scope of delivery, as well as a status LED and a rubber coating on the device make using the Cellularline very convenient.

All in all, the Cellularline Wireless Stand (QX 900 C) a very good overall package at a fair price.

Our test winner convinced, among other things, with the shortest charging time of our test android. Picture: CHIP

    EP-N 5200 Wireless Charger Stand Inductive Charging Station White

    Although our Samsung test device on the Samsung charger does not have the fastest charging time in our test field, it will iPhone 11 Pro loaded fastest here.

Benefits
Shortest charging time of the iPhone 11 Per
Complete scope of delivery
Chic and simple design
Disadvantage
Deductions for efficiency
Charges Samsung smartphone only on average fast
No dual-charge functionality

While the test smartphone from Samsung charges the fastest with the Cellularline test winner, iPhone users are the quickest way to get wireless with a Samsung charger 100 Percent: The Apple cell phone with the Samsung Wireless Charger Stand needs a little over three hours for an inductive battery charge. This is faster than any other charging station tested.

In the test category “Equipment and operation”, the device performs just as well as the test winner, but has to score 2.9 in terms of efficiency (“Satisfactory “) to be satisfied. The reason for this: Samsung consumes almost 1 watt of power in standby mode. Almost all other test devices, however, reduce consumption completely to 0.0 watts. The power consumption is also above average when the smartphone remains fully charged on the charging station.

The price-performance tip: Terratec ChargeAir dot

  • ChargeAir dot

    ChargeAir dot

    Inexpensive and very good: The TerraTe c ChargeAir dot is just behind our test winner in second place. It is also the first choice if it is not a standing device, but a pad.

Inexpensive and only just behind the winner: The Terratec ChargeAir dot

Benefits
Best lying device in the test
Offers a lot for little money
Chic and compact design
Disadvantage
Deductions for efficiency
No dual-charge functionality
position not manually adjustable

The Terratec ChargeAir dot is only marginally worse than the test winner and ends up in second place. The special thing is that it is also the cheapest model in our test. In our price assessment, the Terratec received a grade of 1.0 (“very cheap”). In almost all test scenarios, it achieves a similarly good level as the Cellularline in first place on our leaderboard.

However, it has a minimally higher power consumption when a fully charged Android phone is placed on the charging station, which costs it victory: The Terratec cuts in the “Efficiency” category -Charger accordingly a little worse. Apart from that, the results keep the balance: The Android phone is charged a little slower, the iPhone a little faster, the output power is identical, as is our equipment rating: It has a USB-C socket, as well as a power supply and cable.

The biggest difference: As the product names already suggest, the Cellularline Wireless Stand is an upright device, while the Terratec ChargeAir dot is a charging pad. The cell phone is here with the screen on the ceiling and is more difficult to read during the charging process. If you don't mind this and can live with the marginally poorer efficiency, you will save a lot of money at Terratec without having to forego many features. Therefore, this inductive charging station is also our price-performance winner.

This is how CHIP tests

Every Qi charger has to undergo a detailed test procedure with us. The overall grade results from the results of the categories “performance”, “efficiency” and “equipment and operation”.

  • The main category (70 Percent): Every Qi charger has to “prove its performance”. Both that Samsung Galaxy Note 10 as well as that iPhone 11 Pro will be fully charged in the test starting from zero. We evaluate the battery level of the smartphone according to 30 minutes charging time and the time to fully charge. The results of both smartphones are equally important in the evaluation. In the test it is noticeable: The iPhone generally charges a bit slower, which is why we set the standard for the charging performance of both cell phones independently.
  • The “Efficiency” category results from the power consumption, ie the electricity consumption need, in different application scenarios. It flows with 15 percent in the overall rating. How much power does the charger use if no smartphone is charged? Is electricity still consumed when the smartphone is fully charged? How efficiently do the charging stations charge the smartphone?
  • In the area Equipment and ergonomics (15 percent of the total rating) the grade is made up of many small requirements for the charger. Among other things, we evaluate whether the scope of delivery includes a power supply unit and a cable, whether a status LED is installed on the device, whether the position of the charger is variable on the one hand, on the other hand it is safe and whether several devices can be charged at the same time. We also evaluate special features, such as a double function as a hard disk. However, the weighting for this is very low, since such functions are not one of the primary tasks of a Qi charger.

Minimum requirements and charging standard: wireless charging works for you too

Before you buy a wireless charger, you should make sure that your smartphone supports this function at all. Apple, Samsung and Huawei have long been relying on wireless charging for their top smartphones, but low-budget and often also mid-range phones often come with this function. OnePlus, Motorola and several other brands even completely do without wireless charging. Unfortunately, even the best inductive charging station does not help.

Meanwhile, almost all smartphone manufacturers rely on a uniform charging standard called “Qi”. Charging works under this standard by induction: there is an electrical coil inside the charging station that transforms the current into a magnetic field. There is also a matching electrical coil inside the smartphone, which reverses the transformation. The electrically generated magnetic field becomes electricity again, which is then fed into the smartphone's battery. However, this process is lossy, so you feed more electricity into the charging station than ultimately arrives on the mobile phone. The rest is given in the form of thermal energy.

Dual charger and battery wear: you should still know that

Scientists are still researching whether and to what extent wireless charging is at the expense of the life of a battery. Because part of the energy given off by the charger is converted into heat, which means that the battery temperature during wireless charging can be higher than when charging with a weak 5-watt power supply. For this reason, the wireless charging time is always longer compared to the wired version with the same charging power.

Ultimately, it cannot be ruled out that due to the higher heat development, regular wireless charging will in the long run affect the maximum battery capacity. The same can be said about wired fast charging with a very strong power supply. 18 Watts are no longer uncommon, some models are even equipped with much more powerful power supplies. We currently have no solid evidence to suggest that wireless charging damages the battery to a practical extent compared to conventional charging techniques.

If you want to charge two devices wirelessly at the same time, you get for a little more money so called “Multi Wireless Charger”. Such a charging station is particularly suitable for users of two smartphones, for example for private and business purposes. However, both devices often do not receive the same power supply. In our test, all three dual chargers charged the second device with a lower power than the first device. The charging time for the second device is therefore somewhat longer.
