I've been wanting to buy a 3-in-1 charger for a while, but most of the ones I saw looked like cheap China-imported products and were only in the 30–40,000 won range. I finally found a reliable brand (though it's still made in China 🥲) with a product that offers great value.

It met all the conditions I wanted:
1. Able to rotate the phone freely between landscape and portrait
2. The phone holder's angle is easy to adjust but not loose
3. Comfortable height for desk use at the same time
(Extremely compact ones are great for portability, but they can be a bit inconvenient to keep on the desk permanently.)
4. Still folds fully (maybe impractical for daily use, but portable enough for travel)
5. Black color + a non-tacky design
6. All of the above while costing under 30,000 won

I saw it on Coupang for about 26,000 won, and since I wasn't a Wow member I used the Wow sign-up coupon to get it down by 20,000 won and bought it for around 6,000 won. Considering the Wow membership fee is about 8,000 won, I figure I effectively paid around 14,000 won. I'm very satisfied—highly recommend it to anyone looking for a similar product!! There's also a white color.
