Modern lithium-ion smartphones automatically cut off charging when fully charged, making overnight charging safer. But there’s a charging brick that wants to physically cut off the power for a surefire way of protecting the device being charged.
It is called the HEXIBII/Kuwujia (酷瓦佳) 65W Auto Power-off Charger.
You may have seen HEXIBII/Kuwujia (酷瓦佳)’s viral charger that physically ejects itself from the socket to completely cut off the power. Building on the experience gained from the first model, the new version is worlds apart from its predecessor. If the first was the Iron Age, this new one would be the information/digital age.
Instead of ejecting itself from a socket rather clumsily, the HEXIBII/Kuwujia (酷瓦佳) 65W Auto Power-off Charger remains plugged in and physically disconnects the power internally. It even has a clear section that allows you to see the physical connection and disconnection.
But the golden question is, why bother physically cutting off the power?
Well, let’s face it, risks remain as long as the phone is physically plugged in. If the phone is set to charge to 100%, it runs the risk of repeatedly recharging itself when the battery level drops while it is still plugged in for a long period of time.
There’s also the threat posed by sudden power surges. Even though most charging bricks have protection against sudden surges, let’s be honest, nothing beats physically disconnecting the power.
What if you want to continuously charge a device, you ask? Well, the folks at HEXIBII/Kuwujia (酷瓦佳) have thought of that, too.
It has three charging modes. Pressing a discreet round button lets you choose between optimized fast charging, safe charging, and continuous charging.
Optimized fast charging is good for phones, tablets, and laptops, while safe charging serves up a low current for small devices like earbuds, smartwatches, et cetera. Continuous charging is suitable for devices that need a continuous power supply, like a desktop fan, for example.
On the top side of the charger, you can find the aforementioned mode button, a mode indicator light, a USB-A and a USB-C charging port, and a pop-up button.
When there is contact, this pop-up button is depressed, sitting flush with the top surface. When the device’s charging is complete, or when there’s a short circuit or power surge, it pops up, physically disconnecting the power.
This also means that the next time you want to charge a device, all you have to do is plug it in and push the pop-up button.
HEXIBII says the 65W Auto Power-off Charger is designed to fast-charge MacBook Pro, iPad, and flagship smartphones, supporting the iPhone 15 through 18 series.
It also supports USB PD/PPS fast-charging protocols for Android phones, including Samsung Galaxy, Google Pixel, OnePlus, OPPO, Vivo, and more.
Speaking of phones, the charger will automatically cut power within 10 seconds for the iPhone 15 or newer. However, it will take anywhere from 5 seconds to 50 minutes for other brands, and only after trickle charging is complete.
In the case of power surges, physical disconnection is almost instantaneous, as it is when unplugging the device being charged.
Under the hood, this sleek charger features advanced Silicon Carbide (SiC) semiconductors and 100% brand-new, Grade-A components.
The HEXIBII 65W Auto Power-off Charger is being sold on hexibii.com at a discounted price of US$39.99 (usual price: US$49.99).
Note: I understand that the overuse of AI-generated images on the brand’s website does not exactly inspire confidence. So, I’d proceed with caution, as with any e-commerce site. Or better yet, buy directly from reputable merchants on established Chinese e-commerce platforms. You could save yourself some money, too.
⚠️ Disclaimer: Apparently, in China, the brand is known as Kuwujia (酷瓦佳), and internationally HEXIBII. But here’s the thing. I spoke to Kuwujia’s customer service, and they have no idea about HEXIBII, even claiming Kuwujia does not market it outside of China. I have absolutely no clue what’s going on. While I did provide a link to HEXIBII’s product page, I would suggest buying directly from China if you can. I say that because of HEXIBII’s contact address that I just saw after writing the article.
