UGREEN Nexode Mini 30W USB-C GaN Charger with Cable (25257)
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.
What it does well.
Key features
Quick reference
One USB-C port with a defined 30W ceiling
Connections and roles
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.
The device requests the profile it can use
Negotiated output
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.
Portable power without multi-port complexity
Compact GaN body
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.

Check before buying
Important limitations
Check these points before ordering or connecting:
- Confirm that the device accepts charging through USB-C Power Delivery or another listed protocol.
- Check the device’s required wattage. A laptop designed for 45W, 65W or more may charge slowly or reject a 30W source.
- The charger has an EU two-pin plug. Confirm socket compatibility and obtain a compliant plug adapter if required.
- The exact package includes a USB-C cable, but the India page does not publish its length or detailed power rating; do not assume a particular reach.
- A USB-C-to-Lightning cable is required for compatible Lightning iPhones if the supplied cable is USB-C to USB-C.
- Only one device can charge at a time because there is one output port.
- The USB-C port supplies charging power only and cannot connect displays, storage or other USB data devices.

Setup and usability guidance
Setup 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.
Do and avoid
Good practice
- 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.
- 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.
Warnings and limitations
Safe operation and troubleshooting
Use it safely and troubleshoot methodically.
Safety / limitation 1. Mains equipment must be used only in a compatible, properly installed socket. A plug adapter changes physical fit, not voltage.
Safety / limitation 2. The charger may feel warm during operation. Disconnect immediately if warmth becomes unusual or is accompanied by smell, noise or deformation.
Safety / limitation 3. The 30W figure is a maximum negotiated output. Battery state, device limits, temperature, workload and cable quality affect actual power.
Safety / limitation 4. Some USB-C laptops need more than 30W and can continue losing battery charge during demanding use even while connected.
Safety / limitation 5. Electronic protection features do not replace ventilation, dry conditions and intact cables.

Questions buyers ask.
What is the maximum charging power?
The charger can provide up to 30W to one compatible device. The device and cable must support the negotiated profile.
Does it support PPS?
Yes. PPS is listed for the CD319 family, with an adaptive range around 3.3–11V/2.7A.
Can it charge a laptop?
It can charge a USB-C PD laptop that accepts 30W, but higher-power laptops may charge slowly, only while idle or not at all under load.
Does it have an Indian plug?
No native India plug is specified. This is the EU two-pin version, and no India adapter is listed in the package.
Can I use it on Indian mains voltage?
The charger supports 100–240V AC. You still need a compatible physical socket or a properly rated plug adapter.
Is a USB-C cable included?
Yes, the exact India package lists a USB-C cable. Its length and detailed power rating are not published on that page.
Will it fast-charge every phone?
No. The phone, cable and charger must share a supported protocol. The device decides the actual power and reduces it as the battery fills.
Can I charge an iPhone with it?
Yes, a compatible iPhone can charge through USB-C Power Delivery when used with the correct USB-C-to-Lightning cable; that cable type is not explicitly listed.
Does the USB-C port transfer data?
No. It is a charging output only and does not provide files, video, networking or peripheral data.
Why is charging slower than 30W?
Thirty watts is the ceiling. The device input limit, battery level, temperature, workload, protocol and cable determine actual power.
What safety precautions matter most?
Use a compatible dry socket, allow airflow, keep the plug and cable undamaged, and disconnect for unusual heat, odour, noise or deformation.
