Is this the fast future of wired charging?

Although today all the hype and glory goes wireless charging, MagSafe, and even rumored “real wireless chargers”, wired charging is far from unfinished. In fact, it is going through its own little renaissance! Let’s see how …

The slim and small quick chargers came to light about a year ago when Oppo introduced the mini SuperVOOC charger, which supports 50 W of power despite its small size and weight of 60 grams!

It is no secret to anyone that Realme is owned by the same parent company, Oppo (as well as Vivo and OnePlus). Now we get the first version of this charger sold by Realme, which was released together Realme GT a “flagship killer” phone that recently became global.

Realmen’s ultra-thin SuperDart charger: How is that possible?

The technology behind the quick charger is called “pulse charging” – both Oppo and Realme have removed the electrolytic capacitor and allowed the charger to release huge amounts of power at 40 ms simultaneous time intervals.

Traditional chargers (including quick chargers) increase power. Once they have managed to fill the battery to a certain level – say 70-90%, they will slow down their charge and keep your phone’s battery in good condition.

However, this is not quite your traditional charger. Instead, it uses gallium nitride (GaN). This material entered the charger world relatively recently after it was used to make LED lights in the 90s and for solar cell systems in satellites.

Unlike traditional silicon transistor chargers, GaN chargers produce less heat, making them less space between components. Therefore, GaN chargers can be about 3 times smaller, but still offer a fast charging speed.

The Realmen 50W mini-flash charger uses three high-voltage MLCC filters instead of traditional cylindrical capacitors, allowing it to be so small (LaturiLAB). GaNs are also made of crystalline material. This material can lead to much higher voltages than traditional silicone chargers. This makes the transfer of electricity much faster, resulting in… you guessed it – faster charging (Belkin).

The charger itself is the star of the show, but don’t forget the cable, which is a key part of the equation. In this case, the classic “Realme Yellow” cable supports 20V-5A-100W charging (via USB 2.0). So if you plan to invest in this or buy another GaN charger, make sure you get a suitable cable that will give you everything (unless it is included with the charger).

How GaN chargers change your download experience?

If we leave Apple aside iPhone, every other modern smartphone uses USB-C charging, which is also found in most modern laptops, tablets, and even many of Apple’s own devices.

It took a few years, but USB-C is finally becoming the default way to perform charging, and if Apple finally jumps completely on board, we can finally carry one charger for almost all of our productivity devices.

Foldable charging pin trick makes the pocket a 10mm wide 50W charger that can charge your MacBook iPad, and sorry iPhone users) to your Android phone. It’s great for traveling, moving, and simply carrying just one charger for all your devices.

Indeed, the Realmen mini-flash charger is not going to work the same way everywhere. For example, charging a MacBook takes significantly longer because a MacBook needs a lot more power than a smartphone and uses different power consumption.

According to ChargerLAB, the Realmen 50W mini-flash charger supports VOOC, DASH, WARP, SuperVOOC, PD, PPS, Apple 2.4A and other fast charging protocols. PD devices (up to 27 W) can be supported for other devices.

At the end of the day…

The chargers have come a long way! As mentioned at the beginning, wireless charging is and is now in the spotlight. However, wired charging is far from outdated, especially if you value speed and multi-device compatibility.

Oppo and Realme also make more powerful flash chargers with up to 110 W. They are slightly larger than the small 50 W mini flash charger, but still much smaller than the (96) charger that comes with the MacBook Pro, which rises to just 96 W. .

We look forward to seeing when such compact chargers become the norm and come (or in some cases continue) with the included smartphones, tablets and even laptops!

From now on, the Realmen 50W mini SuperDart charger is only available in China (although you can bring it if you wish). The price is around $ 53, which doesn’t make it exactly cheap, but the convenience might be worth it.
