while in the area Smartphones the big companies like Apple, Samsung or Sony cheaper products on the market gaining on true competition (we reported on that, for example OnePlus 5T) Samsung has had the absolute upper hand in inductive chargers since the dawn of the relatively new technology. With the Samsung EP-NG930 they provide a well-functioning wireless charger with quick charge function, which has been sold extremely much. We have summarized the advantages of other models and what is important in this area for you below.
Induction charging - how does it work?
Wireless charging is becoming more and more popular. The charging stations are fixed next to the bed on which Desk or installed in the living room and that Smartphone you just have to put it on it to load it. The term Qi technology is often used in connection with induction chargers. This term (pronounced "chee" technology) describes the process that takes place in wireless charging. The process itself is by no means new and is used every day in millions of households, for example with the electric toothbrush on the charging station. The term Qi in relation to induction only describes that this technology is suitable for smartphones and Tablets has been divided into two basic categories, which works across brands for every model. One in the category up to 15 watts for smartphones and one in the category up to 120 watts for tablets.
The charging process takes place as follows: An alternating magnetic field is generated in the induction charger with the help of an oscillator. The charge is transferred via two opposing coils - one in the charger and one in the smartphone. The alternating current in the coil of the charger is recorded as alternating voltage in the smartphone and the lithium-ion battery is charged as with a normal cable. In addition, this technology enables more intelligent communication between the smartphone and the charger. Because thanks to sophisticated RFID technology, the charger knows the exact battery level of the end device and stops charging at 100 percent. This protects the battery accordingly.
Is my cell phone Qi-enabled?
Basically, one can say that almost all Android smartphones are Qi-capable, i.e. have a corresponding coil installed. As (almost) always, Apple does its own thing. This is how the Californian group differentiates itself from this movement. After changing the 30-pin charging connector to the small Lightning interface, Apple never entered the "Wireless Power Consortium". The WPC sets a certain standard by which all members can produce smartphones that are charged accordingly via any induction charger. These include, for example, Samsung, LG, Nokia, Googlephones, Sony, HTC, Microsoftphones, etc. Whether Apple will eventually jump on the bandwagon has not yet been clarified. But if wireless chargers continue to enjoy such great popularity, Apple will eventually be unable to look away.
Samsung market leader
Samsung has not only been at the forefront of this technology right from the start, but is now presenting a flagship in the field of induction chargers with the Samsung EP-NG930. Because the built-in "Fast Charge" function reduces the charging time of smartphones by a whopping 40 percent! Inductive chargers used to have a charging time of just under three hours with a completely empty battery. The Samsung EP-NG930 reduces this time to under two hours! This technology is unparalleled to date and makes Samsung's charger the undisputed market leader. The predecessor of the NG930, the PN920, already revolutionized the market with an innovative design and intelligent communication between smartphone and charger.
Nevertheless, of course, other products come onto the market that compete with Samsung. For example, the Wireless Fast Charge from CHOETECH is a real alternative. As the name suggests, the loading time can be reduced to around 70 percent. In view of the lower price and the nevertheless high quality, the WFC from CHOETECH is competition for Samsung.
The price-performance hit is not from Samsung either. The Anker Powerport costs comparatively little, but still has power. Only the design is a bit sparse and fast charging is simply not possible at this price.
Overall, Samsung holds the supremacy in the market of inductive chargers, but as this technology enjoys more and more fans, the competition is obviously not long in coming!
