Does fast charging damage the battery?

No. Phones made from 2020 onwards manage charging speed and temperature themselves, so fast charging is safe for everyday use. If you want to stretch battery life as far as possible, wired charging at a moderate 10–20 W is the gentlest option.

Can I use any USB-C charger?

Yes, USB-C is a common standard. Fast charging, however, only works with a compatible charger (Quick Charge, USB-PD, SuperVOOC). Always use a certified charger — an uncertified one charges slowly and can be unsafe.

Wireless or wired charging — which is better?

Wired is faster and more efficient, because less energy turns into heat. Wireless is more convenient but slower and runs warmer. For long-term battery health wired is slightly better, though with current technology the difference is small.

How powerful a charger do I need?

It depends on the phone: iPhone accepts 20–27 W, Samsung Galaxy 25–45 W, and OnePlus and Xiaomi flagships 80–120 W. There is no need to buy the most powerful one — 20–30 W is enough for most phones and works with everything.

What power bank capacity should I choose?

10,000 mAh covers normal use — two to three full charges. If you travel a lot, 20,000 mAh is the better choice. Check the output power too: 20 W or more means the power bank can fast charge.

Description

Crong Ultra Compact GaN is a compact black indoor mains charger with manufacturer code CRG-GNCC35-BLK. It has two USB-C outputs and a maximum combined power of 35 W. GaN electronics allow a small 39.5 × 39.5 × 28 mm enclosure while supporting compatible phones, tablets and other USB-C devices.

USB Power Delivery 3.0, PPS and Quick Charge 3.0 are supported. Fast-charging mode and actual speed require a compatible device and a suitable cable; unsupported devices negotiate an available standard profile.
With one port in use, up to 35 W is available. With two devices connected, Dynamic Power Allocation shares the same 35 W total according to device needs and connection order; it does not provide 35 W to each port.
The 100–240 V AC input is suitable for compatible mains supplies. Use an undamaged socket and cables rated for the required power, and disconnect the charger if its housing, pins or cable are damaged.
The manufacturer specifies a fire-resistant polycarbonate housing and a triple protection system. These features do not eliminate heat: use the charger in a dry, ventilated indoor location and do not cover it while operating.
Charging time depends on the device, battery state, cable, selected power profile and simultaneous load. Reconnecting another device may cause power to be renegotiated briefly between the two ports.

The package contains one mains charger. USB-C cables and devices are not included.
