Compact single-port 30W GaN charging
UGREEN Nexode Mini 30W USB-C Charger | 25257
A compact EU-plug GaN wall charger with one USB-C output, up to 30W Power Delivery and PPS/QC support. The India bundle includes a USB-C cable; actual charging speed is negotiated by the connected device.
Product introduction
Overview
UGREEN model 25257 is the cable-bundle variant of the Nexode Mini CD319 30W charger. It plugs directly into a compatible EU-style two-pin socket and provides one USB-C charging output for a phone, tablet, handheld device, power bank or lower-power USB-C laptop.
The charger negotiates the supported voltage and current with the connected device. It can provide up to 30W through USB Power Delivery, with PPS and several widely used fast-charge protocols. A device that accepts less than 30W draws only its supported level.
Its single-port design means the full available output is not divided across other devices. The tradeoff is that only one device can charge at a time, and there are no USB-A, data, video or hub functions.
Quick reference
Key features
Connections and roles
One USB-C port with a defined 30W ceiling
USB-C output
Use the included or another suitable USB-C charging cable for compatible USB-C, Lightning or proprietary device inputs.
EU wall plug
The two round pins are the EU version. Confirm socket fit or use a properly rated compliant plug adapter where needed.
30W maximum
The charger cannot exceed 30W, even when connected to a cable or laptop rated for higher power.
Charging only
The USB-C port supplies power. It is not a data, display, Ethernet or peripheral connection.
Negotiated output
The device requests the profile it can use
The CD319 family is specified for 5V/3A, 9V/3A, 12V/2.5A, 15V/2A and 20V/1.5A fixed profiles, plus PPS around 3.3–11V/2.7A. The charger and device choose a mutually supported profile rather than sending 30W continuously.
Charging normally slows as a battery fills or temperature rises. Screen activity, navigation, gaming or laptop workload can also reduce the visible rate at which the battery percentage increases.
- PD 3.0/2.0 and PPS support compatible USB-C devices.
- QC 4+/4.0/3.0, SCP, FCP and AFC support remains device- and cable-dependent.
- A high-wattage cable does not make a device draw more than its designed input.
Compact GaN body
Portable power without multi-port complexity
GaN technology allows the charger body to remain compact at approximately 32 × 32 × 40mm and about 57g for the charger itself. The larger dimensions and weight shown in the India storefront are consistent with retail packaging and should not be presented as the wall-charger body.
Compact electronics still produce heat while converting power. Use the charger in an open, dry location, keep the surrounding socket area unobstructed and remove it by holding the body rather than pulling the connected cable.
- One port keeps output selection simple.
- EU plug is fixed; no foldable or native India plug is specified.
- Fire-resistant PC and thermal/overcurrent/overvoltage/short-circuit protections are listed for the CD319 family.

Setup guidance
Setup and usability guidance
- Inspect the charger, plug and USB-C cable for damage before use.
- Confirm that the wall socket accepts the EU two-pin plug, or fit a properly rated compliant adapter without forcing it.
- Insert the charger fully into a suitable dry mains socket with clear space around the body.
- Connect the USB-C cable to the charger, then to the device.
- Check the device’s charging indicator; any “fast” or “super fast” label depends on the model and negotiated protocol.
- If charging is slow, close high-load applications, try the supplied cable or another known-rated cable and confirm the device’s input specification.
- Unplug from the mains before cleaning and use only a soft, dry cloth.
Good practice
Do and avoid
What to do
- Use a suitable socket or correctly rated plug adapter.
- Use a cable appropriate for the device connector and requested power.
- Keep the charger exposed to normal airflow on a dry wall socket.
- Check the device’s stated USB-C input before relying on it for laptop charging.
- Disconnect it if heat, odour, sound or physical condition seems abnormal.
What not to do
- Do not force the EU pins into an incompatible socket.
- Do not cover the charger or use it under bedding or behind heat-trapping material.
- Do not expect a 30W charger to replace a 65W or higher laptop supply under full load.
- Do not use frayed cables, loose adapters or wet electrical connections.
- Do not interpret the USB-C port as a data or display output.
Safe operation and troubleshooting
Warnings and limitations
Use it safely and troubleshoot methodically
