@路中南: Hagibis Qi2.2 Double-Sided Magnetic Wireless Charger

• Reference Price: ¥99

In my review of that Qi2.2 charging stand with active cooling from the previous issue, I mentioned at the end that the Qi2.2 protocol itself has significantly improved thermal management, making passive cooling more than sufficient. I also casually suggested that those early-generation 7.5W magnetic chargers were probably due for retirement. Since I’d already said it publicly, I couldn’t exactly leave the charging spots around my own home untouched, so I ended up buying three different products to upgrade to the new standard. It also turned into a small comparison test of sorts:

• Both passively cooled models place the power management chip on the USB-C end rather than inside the magnetic charging pad itself, separating the heat source from the charging surface and reducing heat buildup;
• The budget model that cost around ¥40 felt underwhelming in both packaging and build quality. This Hagibis model looks far more polished and also supports double-sided magnetic attachment, which was the feature I was most interested in trying;
• The actively cooled double-sided magnetic version costs even more and is positioned more toward gaming users. The cooling system is clearly the main attraction, while charging and RGB lighting are optional features that can even be turned off. It does seem ideal for running performance tests on a phone, though.

Double-sided magnetic attachment is a surprisingly clever design. What makes it clever is that it allows magnetic accessories to attach to other magnetic accessories. Any magnetic stand or charging base you already have at home can attach to one side, while your phone attaches to the other, instantly creating an additional Qi2.2 wireless charging spot. Buying it feels less like purchasing a charger and more like unlocking the potential of all those magnetic accessories you already own. Hagibis also sells matching desktop stands and magnetic semiconductor cooling accessories, but they aren’t cheap, so I skipped those.

Before buying it, I was worried that removing the phone might pull the charger off along with it. After testing, I found that the magnetic strength on each side isn’t the same. The aluminum-alloy side on the back has a noticeably stronger magnetic connection, so that concern turned out to be unfounded. Speaking of the aluminum alloy, it also contributes a bit to heat dissipation. Another advantage is that the Qi2.2 protocol can adapt dynamically to different input power levels and doesn’t strictly require a 15V/3A power source. In my testing, it worked perfectly fine with a 9V/2A adapter.

What really made this charger earn its keep, though, was an unexpected use case. A friend of mine drives a Tesla and absolutely refuses to use the built-in Baidu Maps navigation, insisting on using Amap on his phone instead. Tesla’s factory wireless charging tray charges slowly, makes navigation difficult to view, and turns the phone into a hand warmer. It’s basically decorative. So I bought another magnetic mount and installed it right below an air-conditioning vent. Snap this Hagibis charger onto it, and the problem is solved. Cool air blows directly onto the aluminum backplate while the phone runs Amap navigation. By the end of the drive, the phone stays cool and fully charged, with no need for additional active cooling at all.

@怡宝: Miwu Wireless Silent Mouse

• Reference Price: ¥20

While browsing Xianyu, I came across this brand-new, still-sealed mouse. The seller even threw in a power bank (with wireless charging and 3C certification), and at just ¥20, it was simply too good a deal to pass up. Without thinking twice, I bought it. The seller also included a USB-C charger, so I’d say this bargain hunt was definitely a success 😝

This little mouse happens to fit my needs perfectly. Silence is my top priority, making it ideal for office use. As an introvert, the last thing I want is to disturb others while they’re resting, so a silent mouse is a must—keep love & peace. Compared to Bluetooth mice (I normally use a Logitech Pebble 2 at home, which still has a soft click sound), I actually prefer this type of mouse with a 2.4GHz wireless receiver. The receiver can be stored inside the compartment on the back of the mouse, so there’s no need to worry about losing it.

It measures 32mm × 115mm, with a cute, rounded shape that fits my relatively small hands nicely. For a ¥20 mouse, it even offers three DPI settings. Although the maximum is only 1600 DPI, that’s more than enough for everyday use. The red-and-white color scheme also pairs perfectly with my K3 Max keyboard. As someone with a bit of obsessive attention to visual consistency, that combination is incredibly satisfying to look at. It can even operate using just a single battery, which turned out to be unexpectedly practical. For ¥20, what more could you possibly ask for? 😄

@西鸽: Supor Modular Food Warming Tray

• Reference Price: ¥246

I’m one of those working folks who has to get up at 6:30 every morning to cook. After preparing breakfast and lunch, I leave the dishes on the table, wash the rice, and set my Xiaomi rice cooker on a timer so everything is ready by the time my child comes home from school around 12:30. A while ago, my child took a plate of food to the microwave to reheat it. The plate came out too hot to handle and ended up being dropped on the floor. That’s when I started wondering whether there was a way to keep food warm so my child wouldn’t have to reheat it alone.

After looking around, I settled on a food warming tray. Some models in Supor’s lineup can even be used to keep a hot pot simmering directly on the surface. My needs, however, were much simpler: cook in the morning and keep the food warm until lunchtime.

The warming tray is made up of three modular sections. Most of the time, I only plug in the first section because I usually prepare just two dishes in the morning, and one panel is enough. It can be expanded to two or three connected sections, reaching a maximum size of 60 × 40 cm, which provides plenty of room for multiple dishes.

Before buying it, I did a bit of research. Some of the latest warming trays use flexible silicone mats that can be rolled up for storage. However, I figured a metal surface would be easier to clean. A quick wipe with a wet cloth and it’s spotless.

The model I bought is the 822D. It offers nine temperature settings ranging from 40°C to 120°C. Most of the time I simply leave it in the default warming mode, which is 100°C. Once warming mode is activated, the surface becomes noticeably hot to the touch in just over ten seconds. For the best heating performance, it’s recommended to use plates with completely flat bottoms rather than those with raised circular feet, allowing full contact between the plate and the warming tray.

There are also several other modes for tasks like defrosting and warming milk, though I rarely use them. I’ve heard people even use it to warm dried sweet potatoes or heat up socks. Living in southern China, though, I don’t think I’ll ever have a need for that.
