The UGREEN brand has long since stopped being associated with cheap cables. The company has been consistently building an ecosystem of quality accessories, releasing more and more products that keep improving in quality. It even has its own recognizable brand identity, and its two new products — the Revodok CM886 hub and the PB552 power bank with 25,000 mAh — perfectly demonstrate where the brand is heading. At first glance, these are just a hub and a power bank, but if you look closer, it becomes clear that both devices were designed by people who actually use them. Let’s break down what makes them worth getting and where you’ll have to compromise.
These are more than just two accessories.
UGREEN Revodok 12-in-1 CM886 — The Best Hub for a Laptop
The idea behind the UGREEN Revodok 12-in-1 is simple and elegant: you connect a single USB-C cable to your laptop and get a full-fledged desktop with everything you need. No adapters, no scattered wires — just one hub on your desk and cleanliness all around. There’s nothing new about the idea itself, but what matters is that this isn’t just another generic hub.
The body is made of aluminum, which not only looks nice but also functions as a passive heatsink: under load, the device gets noticeably warm but never reaches alarming temperatures. This is an honest engineering solution, far better than plastic that traps heat inside, increasing the risk of unpleasant consequences. This could be anything from premature failure to short circuits and even fire.
The body is metal.
The port selection is very well thought out, rather than assembled on the “more is better” principle. Two HDMI and one DisplayPort allow you to connect up to three monitors: a single display is supported at 4K 144 Hz, two displays simultaneously at 4K 60 Hz, and three at 4K 30 Hz. This is useful for video editing or working with a large number of windows, although 30 Hz on the third monitor is more “it works” than “it’s pleasant to work with.”
One side.
The other side.
For those who actively transfer files, there are two USB-C 3.2 Gen2 ports with data transfer speeds up to 10 Gbps, a pair of USB-A 3.0 ports, and two USB-A 2.0 ports for simpler peripherals like mice and keyboards.
Worth noting separately are the gigabit Ethernet, SD and microSD card slots with speeds up to 104 MB/s, a 3.5 mm audio output with 192 kHz/24-bit support, and a 100W Power Delivery port, of which up to 85W goes to the laptop, with the rest being sufficient to power connected devices.
Charging speed is very important. Many hubs exaggerate their charging power, losing 20–30W to their own needs and simply heating as a side effect of operation, but here the losses are minimal. In practice, Ethernet works stably and without dropouts even during long video conferences, and all USB devices are recognized without delays when connected.
Through just one USB-C, you can connect a whole lot of things.
The main nuance you need to know in advance: the USB-C data ports don’t support video output and charging simultaneously — they’re exclusively for data transfer. For most users, this isn’t critical, but if you were planning to use one of these ports for a second monitor via an adapter, you’ll need to rethink your connection setup. Otherwise, there are no complaints about the hub — it does exactly what it promises, and it does it reliably.
UGREEN Nexode PB552 — A Power Bank for Everything
The UGREEN Nexode PB552 power bank is a device for those who are tired of carrying a separate power adapter for their laptop and don’t want to choose between charging a laptop and a smartphone. The capacity is 25,000 mAh, and the maximum total output is 165W, which allows you to simultaneously charge a laptop, smartphone, and tablet without any compromises.
The main feature of the PB552 is two built-in USB-C cables with magnetic attachment. The first supports up to 100W, the second up to 65W. This solves the eternal problem of the forgotten cable. This power bank is completely self-sufficient, and you don’t need to rummage through your pockets looking for a cord.
Two cables are already built into the body.
In addition to the built-in cables, there’s a full USB-C port supporting up to 140W, another USB-C at 20W, and a USB-A at 22.5W — four outputs total simultaneously, but still no more than 165W combined. In any case, this is enough to power a laptop, phone, tablet, and earbuds all at once, and nothing will be left out. Charging the power bank itself from zero to 100% takes about two hours via the 100W USB-C input. The key is having a powerful power adapter, but many people already have one, and if not, they’re inexpensive.
When folded, one of the cables can be used as a strap. But don’t overdo it.
Inside, five 21700 lithium-ion cells are used, which have a better lifespan compared to the standard 18650 cells found in most budget competitors. Protections against overheating, overload, and short circuit are all present in full — everything as it should be.
For comparison, next to a 20,000 mAh power bank and iPhone 13 Pro Max.
The weight is 513 grams with dimensions of 169 × 80.7 × 26.7 mm: not record-breakingly light, but quite reasonable for this capacity and power. Taking it on a day trip is no hassle; it’s practically unnoticeable in a backpack. But it can charge all your gadgets at least once, and if you only have a smartphone, it should be enough for 3–5 charges.
There’s also a low-power device charging mode, activated by holding the button for three seconds — useful when you need to charge TWS earbuds or a smartwatch without wasting charge on maintaining high power output idly.
By pressing the button, you can turn on the screen and check the remaining charge.
