UGREEN CD130 40858 30W USB-C + USB-A Car Charger
A compact aluminium 1C1A vehicle charger with a 30W USB-C PD/PPS output, an up-to-22.5W USB-A output and a conservative explanation of the 30W shared-system limit.

Overview
UGREEN 40858 provides one USB-C and one USB-A charging output from a compatible 12–24V accessory socket. USB-C can reach up to 30W by itself through 5V/3A, 9V/3A or 12V/2.5A profiles, with PPS support. USB-A can reach up to 22.5W alone through high-current 5V-class profiles. The charger is rated at 30W total, so connecting both devices does not create 52.5W of simultaneous output. Exact regional documents do not list one consistent per-port dual-use split; this guide intentionally avoids inventing one.
Best-fit summary: Drivers who want one modern USB-C fast-charge connection and one USB-A fallback in a small metal charger, primarily for phones, tablets and portable electronics.
Key features
Strongest mode
Use USB-C by itself for the verified 30W PD/PPS ceiling.
USB-A reality
USB-A can reach 22.5W alone with a compatible SCP/high-current device; ordinary QC devices may negotiate a lower profile.
Two-port limit
Both devices share a 30W system budget. Do not add the two single-port figures.
Port map and connector roles
USB-C
5V/3A, 9V/3A or 12V/2.5A; up to 30W; PPS supported within the documented range.
USB-A
5V/3A, 5V/4.5A or 4.5V/5A; up to 22.5W with a compatible device.
Port labels matter: Use USB-C when the priority device supports PD or PPS. Treat USB-A as a secondary fast-charge or legacy-cable output.
Exact power allocation
| USB-C alone | Up to 30W. |
|---|---|
| USB-A alone | Up to 22.5W. |
| USB-C + USB-A | 30W maximum total, dynamically shared. Exact per-port split varies with negotiated device profiles and is not consistently published across regional exact-SKU sources. |
Read the table before buying: 30W is the charger-wide maximum. The 30W USB-C and 22.5W USB-A values are single-port ceilings and must not be added together for dual use.
Charging protocols and speed logic
Exact SKU sources list PD 3.0 and PPS on USB-C plus QC 3.0, FCP, AFC, BC1.2, DCP, Apple 5V/2.4A and Samsung 5V/2A families across the supported outputs. A protocol name does not guarantee the maximum headline wattage: the device chooses a compatible profile and shared use remains constrained by the 30W system limit.
USB-C PD/PPS
Best suited to compatible iPhone, iPad, Galaxy, Pixel and other devices accepting a 30W-or-lower USB-C input.
USB-A fast-charge
Supports high-current 5V profiles and common QC/FCP/AFC families, with up to 22.5W only on compatible hardware.
Shared operation
Adding the second device can change both charging labels and rates because the unit stays within 30W total.
Compatible devices and systems
Phones and tablets
Compatible iPhone, iPad, Galaxy, Pixel and other USB-charged phones or tablets can use the charger with the correct cable. The device still decides the accepted voltage, current and charging label.
Portable electronics
Suitable for USB-charged headphones, cameras, navigation units, handheld consoles, speakers, e-readers and power banks when their input matches a listed profile.
Vehicles
Designed for compatible 12V and 24V accessory or cigarette-lighter sockets. Socket depth, contact condition, fuse rating and whether the outlet stays live while parked are vehicle-specific.
Computers
A USB-C laptop is compatible only if it accepts USB Power Delivery within the stated port ceiling. Some high-performance laptops may charge slowly or only while sleeping.
Compatibility rule: This model can physically connect to many devices, but the useful rate depends on protocol negotiation. It is not a general replacement for a 45W, 65W or higher laptop adapter.
Use scenarios
Daily commute
Fast-charge one compatible phone on USB-C while keeping USB-A free for occasional accessories.
Two-phone trip
Charge two devices together, understanding that both share the 30W system budget.
Navigation plus earbuds
Keep a navigation phone powered and top up a small accessory from the second output.
Mixed cable bag
Continue using an existing USB-A cable alongside a newer USB-C-to-USB-C cable.
Setup and usability guidance
- Park safely before fitting or changing any cables. Confirm that the vehicle outlet is a clean, dry, undamaged 12–24V DC accessory socket.
- Insert the charger fully. If there is no power, check whether the vehicle energises that socket only in accessory or ignition mode.
- Connect the highest-demand device to the port identified in the power table; then add lower-demand devices one at a time.
- Route every cable away from the steering wheel, pedals, gear selector, handbrake, seat rails and airbag deployment areas.
- When finished, disconnect devices first. Remove the charger if the vehicle keeps the outlet live while parked and prolonged standby draw is a concern.
No software required: The charger is plug-and-play; correct socket fit, port choice and cable routing are the important setup decisions.
Everyday usability and care
Automatic negotiation
There is no manual voltage switch. The charger, cable and device negotiate a mutually supported profile.
Shared-power awareness
Adding a second or third device can change the available power and briefly reset the active outputs.
Cable choice
Use the correct connector and a cable rated for the requested current. A phone cable is not automatically suitable for laptop-class power.
Heat and ventilation
Keep the housing exposed to cabin air. Warmth can be normal; abnormal heat, smell or cycling is not.
The aluminium shell can feel warm because it transfers heat away from the internal electronics. Keep the body visible and ventilated, and remove it by gripping the charger rather than pulling an attached cable.
What this product does
- Converts power from a compatible vehicle accessory socket into regulated USB charging outputs.
- Negotiates a mutually supported charging profile with each device and reallocates available power as connections change.
- Charges phones, tablets, accessories and—only where the stated port power is sufficient—compatible USB-C computers.
- Works without an app, driver, Bluetooth connection or vehicle infotainment pairing.
What this product does not do
- It is not an AC inverter and cannot power equipment that requires a household wall outlet.
- Its USB connectors are power outputs, not data, CarPlay, Android Auto, display or file-transfer ports.
- It cannot force a device to accept more power than the device, cable and protocol permit.
- It does not contain a battery and cannot continue charging after the vehicle socket loses power.
- It does not supply 30W from USB-C and 22.5W from USB-A simultaneously; total output is capped at 30W.
- Do not buy it as a guaranteed full-speed charger for a laptop that normally requires 45W or more.
What to do
- Use sound, correctly rated cables and place the highest-demand device on the strongest documented output.
- Keep the charger exposed to cabin air and keep the accessory socket free of dust, liquid and conductive debris.
- Expect a brief charging pause when a device is connected or removed; many multi-port chargers must renegotiate power.
- Check the connected device’s input requirement instead of judging compatibility from connector shape alone.
- Disconnect power before cleaning and use only a dry, soft cloth.
- Use only the USB-C port when a device needs the strongest documented output.
What not to do
- Do not use a wet, loose, scorched, cracked or mechanically damaged vehicle socket, charger or cable.
- Do not cover the charger with fabric or wedge it where ventilation is blocked.
- Do not exceed the stated 12–24V DC input range or connect it to an unverified power source.
- Do not handle connections while driving when doing so could distract the driver or interfere with controls.
- Do not disassemble the housing or continue use after deformation, burning odour, repeated shutdown or abnormal heat.
- Do not interpret separate single-port ceilings as a 52.5W combined rating.
Warnings and limitations
- The vehicle outlet and its fuse must be capable of supplying the requested load. A weak or damaged socket can cause intermittent charging.
- Charging power normally falls as a battery approaches full charge or becomes warm. This tapering is expected and is not proof of a charger fault.
- Metal and high-output charger bodies can feel warm during normal operation. Stop use if heat becomes excessive or is accompanied by smell, deformation or repeated cut-outs.
- The product is not described as waterproof. Protect it from spills, condensation and wet cleaning.
- A printed wattage is a ceiling under defined conditions, not a promise that every device will draw that amount.
- Regional exact-SKU listings conflict on the precise two-device split. The safe buying assumption is a 30W dynamically shared total.
Stop-use trigger: Disconnect immediately if you notice arcing, smoke, a burning smell, melted plastic, visible deformation or repeated unexplained power loss.
Troubleshooting
No power
Check ignition/accessory mode, reseat the charger, inspect the socket and test a second known-good vehicle outlet if available.
Charging is slow
Test one device alone, use the strongest documented port, verify the cable rating and check the device battery temperature and state of charge.
Power cuts in and out
Inspect for a loose socket fit, debris, worn side contacts or a damaged cable. Repeated cycling is not normal when connections are unchanged.
Fast-charge label is missing
Confirm that the port, cable and device share the required PD, PPS, QC or manufacturer-specific profile. A standard fallback charge may still work.
Useful diagnostic: If fast charging disappears when the second cable is connected, test the priority device alone on USB-C. That isolates power sharing from cable or device incompatibility.

Product-specific FAQ
What is the maximum output?
The charger-wide maximum is 30W. USB-C can reach 30W alone, while USB-A can reach up to 22.5W alone with a compatible device.
How does power change when more than one device is connected?
Two devices can charge together, but they share a 30W total budget. Exact regional sources do not state one consistent fixed split, so no unsupported per-port promise is made here.
Can it charge a laptop?
Some low-power USB-C laptops may accept 30W, but many computers require 45W, 65W or more. It is primarily a phone, tablet and accessory charger.
Which port should I use first?
Use USB-C for the priority PD/PPS device. Use USB-A for a legacy cable or compatible fast-charge accessory.
Does it support fast charging?
Yes. USB-C supports PD 3.0 and PPS, and the charger supports common QC/FCP/AFC and standard USB charging families. Shared use can reduce the rate.
Will it work in a 24V truck or commercial vehicle?
It is specified for compatible 12–24V DC vehicle sockets, subject to proper mechanical fit and sufficient outlet capacity.
Why can charging briefly stop when another device is connected?
The charger may reset and renegotiate its output when the active port combination changes. A short pause is normal; repeated cycling without a connection change is not and should prompt a cable, socket and device check.
Why is the real charging speed lower than the printed wattage?
The printed figure is a maximum. Device input limits, cable capability, battery level, temperature, active-port sharing and the available power source all influence the real rate.
Does it transfer data or connect to an infotainment system?
No. The USB connections on this charger are for charging power only; they do not carry files, video, CarPlay or Android Auto data.
What is included in the package?
One UGREEN 40858 car charger is confirmed. A separate charging cable is not listed as included.
How do I confirm this is the correct model?
Match SKU 40858 and, where shown, model CD130 on the product or retail label before relying on this page's port and power tables.
