REDMAGIC DAO 100W 2-in-1 USB-C Charging Cable Review: Cleaner Desk, Better Cooling Power
After using this Red Magic one-to-two data cable for a week, the other cables on my desk can all be put away
To be honest, when I first saw this cable, my first reaction was: another flashy gaming peripheral. But after truly using it for a week, I quietly coiled up those two charging cables on my desk and put them away in a drawer.
Charging while gaming, finally no more "fighting" between cables
As a player who plays Honor of Kings for two to three hours every day after work, the most troubling thing isn't winning or losing, but the fact that when my phone is plugged into a charging cable while gaming, that cable is always wrestling with my hand. When holding the phone in landscape orientation, the cable connector presses right against the base of my right thumb, and my hand gets sore after playing for a while. What's even more uncomfortable is that if I also have the cooler running at the same time, the desktop is basically a spider's web cave—one cable for the phone, one cable for the cooler, the two cables tangled together, and the slightest movement would pull the cooler askew.
This one-to-two design from Deuterium Front made me feel for the first time that "so charging doesn't have to be this awkward after all."
After the angled connector is plugged into the phone, the cable runs down along the edge of the phone's frame, completely out of the way of my hand. I specifically tried playing in landscape mode for over an hour, and my hand felt completely unaware of the cable's existence, somewhat similar to the "no sense of presence" feeling you get when listening to music with wireless earphones. The straight connector end is plugged into the cooler, and because the cable's routing goes downward, it also doesn't interfere with the phone's cable.
The cooler's "Destruction God Mode" has truly been fed enough
I previously used an ordinary one-to-two cable, and the cooler could still spin when plugged in, but it always felt like the airflow wasn't strong enough. Later I found out that cable was splitting the power evenly, so the cooler simply couldn't get enough electricity, and the so-called "Destruction God Mode" was just for show.
After switching to this cable, the most immediate difference was that the cooler sounded different. Once plugged in, you could clearly hear the fan speed pick up, the sound became deeper and more powerful than before, and the cooling surface temperature dropped especially fast. While running around in Genshin Impact, the back of the phone stayed consistently just warm, unlike before when it would get too hot to touch after only a little while of playing. This feeling is like a car finally getting 95-octane gasoline, with the engine finally able to deliver its true horsepower.
50cm split section, the desktop is finally tidy
Normally I place a 100W charging head on the desk, with the cable running across the desktop. When I used two separate cables before, the desk was always a mess. This cable's total length of 150cm is enough to extend from the desktop to the sofa or bed, and the 50cm split section is just enough to create distance between the phone and the cooler. With the cooler attached to the back of the phone, the split section divides in the middle, and the two cables each run downward separately, making the desktop look a lot cleaner.
There's also an unexpected useful scenario—when duo-queuing with a friend on the weekend, one cable can charge two phones at the same time, so the two of us don't have to fight over a charging head. The 50cm split length is just enough for two phones to sit side by side, and neither person has to give way to the other's position.
Some details on the feel
The nylon-braided cable body feels somewhat harder to the touch than an ordinary silicone cable, but the benefit is that it doesn't tangle easily. The silicone cable I used before would always get tangled into a knot when taken out of my bag, and it would take half a minute to untangle. I tried crumpling this cable into a ball and stuffing it into my bag, and when I took it out and gave it a shake, it naturally came undone with almost no creases.
The metal material of the connectors feels cool to the touch, with a very solid texture. When plugging and unplugging, you can feel that the connection is held very tightly, unlike some cables that become loose after prolonged use. I specifically paid attention to the elongated section at the base of the connector—several cables I've broken in the past were all due to that spot repeatedly bending back and forth, causing the internal wire core to break. This cable's design clearly reinforces this weak point.
Some honest thoughts
This cable isn't perfect. The scenario it's suited for is actually quite clear—if you don't have a cooler, or don't usually play games in landscape mode, then it's just an ordinary one-to-two cable, and you won't feel most of its advantages. But if you play games with a cooler plugged in every day and can't stand cables flying all over your desk, then the improvement in experience this cable brings is real and tangible.
After a week of use, the biggest impression actually isn't "how fast the fast charging is" or "how strong the specs are," but rather a feeling of "just right" convenience—once it's plugged in, you don't have to worry about it anymore, your hand never touches the cable, the cooler runs at full power, the phone's battery doesn't drain, and the desktop stays clean. This kind of comfort in the details is probably about the best state an accessory product can achieve.
