This is the English edition of a review from my Japanese YouTube channel, iestaLife. I review gadgets from my home studio in Japan, so product links go to Amazon Japan.
Quick take
UGREEN's 100W charger with a built-in 75 cm retractable USB-C cable is for people who are tired of loose charging cables. It charges up to four devices and you never have to remember a cable, but at 300 g it is not a light charger.

What I tested
- UGREEN 100W USB-C charger with a built-in 75 cm retractable cable
- Pulling out and retracting the cable, and the magnetic cable tip
- Weighing it on a kitchen scale
- Charging an iPhone from the built-in cable
What I found
- Four ports in a palm-sized body: besides the retractable USB-C cable, it has two USB-C ports and one USB-A port, so up to four devices at once.
- Thoughtful details: the AC prongs fold flat, and the cable tip snaps onto the body with a magnet, so nothing dangles in your bag.
- Easy retraction: pull the cable all the way out, give it a little extra tug, and it winds back in.
- Weight: exactly 300 g on my scale. Compact, but you feel it.
- Price: 4,980 yen at the time of recording (list price 7,980 yen). I think that is fair for a 100W charger.

| Item | Detail |
|---|---|
| Max output | 100W |
| Built-in cable | USB-C, 75 cm, retractable |
| Other ports | 2× USB-C, 1× USB-A |
| Weight (my measurement) | 300 g |
| Price (at the time of recording) | 4,980 yen |
How I plan to use it
My main reason for buying it: I want to stick it to the side of my desk with hook-and-loop tape, leave it plugged in, and pull out the cable only when I need it. That keeps the desktop free of tangled cables. Because it weighs 300 g, it needs to be fixed firmly.
For trips, this charger plus three cables covers four devices, including a laptop, phone and camera. And if I forget my cables, the built-in one still charges one device.

Who it's for
- People who want a tidy desk and a cable that appears only when needed
- Travelers who want one charger that can also handle a laptop
- Not ideal if a light charger matters most to you
Watch the review
The video is in Japanese. The cable demo starts around 1:50, and the weigh-in is around 2:23.
Limitations
This was a first-impressions review: I tested basic iPhone charging but did not measure charging speeds or heat. The price was Amazon Japan's at the time of recording.
