Overview
UGREEN 10144 provides two equivalent USB-A fast-charge outputs. Each port supports 5V/3A, 9V/2A or 12V/1.5A, up to 18W, and both ports can deliver their 18W ceilings together for a total of 36W when paired with compatible devices. It supports QC 3.0/2.0 and several common USB-A charging families, but it has no USB-C port and does not provide USB Power Delivery or PPS.
Best-fit summary: Two-phone households or shared vehicles that still use USB-A cables and want two simultaneous 18W QC-class outputs.
Key features
True dual 18W
Both ports can reach 18W at the same time for a documented 36W total.
USB-A only
USB-C devices require USB-A-to-USB-C cables and do not gain USB PD/PPS from this charger.
Vehicle-ready input
Rated for compatible 12V and 24V accessory sockets.
Port map and connector roles
USB-A port 1
5V/3A, 9V/2A or 12V/1.5A; up to 18W.
USB-A port 2
5V/3A, 9V/2A or 12V/1.5A; up to 18W.
Port labels matter: Both ports are equivalent. Choose the cable route that is safest and most convenient; neither output is a higher-power priority port.
Exact power allocation
| One USB-A port | Up to 18W. |
|---|---|
| Two USB-A ports together | Up to 18W + 18W = 36W total. |
Read the table before buying: A device must support a listed USB-A fast-charge profile to draw 18W. Ordinary 5V-only devices will safely charge at a lower negotiated level.
Charging protocols and speed logic
Both ports support QC 3.0/2.0, FCP, AFC, Apple 5V/2.4A and BC1.2 families. There is no USB-C receptacle and no PD or PPS claim. An iPhone or USB-C device can still charge through the correct USB-A cable, but its protocol and power ceiling will differ from a modern USB-C PD charger.
QC 3.0 / 2.0
Compatible devices can request up to the port’s 18W ceiling through the stated 5V, 9V or 12V profiles.
Apple 5V mode
Compatible Apple devices can use a standard USB-A charging profile with the correct Lightning or USB-C cable.
No PD/PPS
The absence of USB-C means it cannot negotiate USB Power Delivery or programmable PPS charging.
Compatible devices and systems
QC-capable phones
Suitable for many Galaxy, Xiaomi, Huawei and other compatible phones using an adequate USB-A cable.
Apple devices
iPhone, iPad, AirPods and related devices can charge with the correct USB-A cable; actual rate depends on the model.
Portable electronics
Works with compatible power banks, navigation units, cameras, speakers, headphones and other USB-A-powered accessories.
Vehicles
Specified for compatible 12V or 24V accessory sockets in passenger and commercial vehicles.
Compatibility rule: USB-A connector fit does not guarantee QC 3.0. Unsupported devices fall back to a mutually supported lower profile.
Use scenarios
Two-phone road trip
Give each compatible phone a dedicated 18W USB-A output.
Driver plus passenger
Keep navigation and mobile data active on one phone while charging a passenger device from the second port.
Phone plus power bank
Charge a compatible phone and replenish a power bank at the same time.
Legacy cable setup
Keep existing USB-A cables in service without moving to USB-C PD hardware.
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 body is compact and can become warm as it dissipates heat. Keep it uncovered, inspect the side contacts periodically and remove it by the body rather than a connected 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 provide USB-C PD, PPS or a USB-C physical connection.
- Do not choose it for a laptop, Steam Deck-class device or another product requiring USB-C PD.
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 a cable known to support the device’s USB-A fast-charge standard; cable quality can determine whether 18W negotiation succeeds.
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 assume a USB-A-to-USB-C cable turns this into a USB-C PD charger.
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.
- The aluminium housing can feel warm under a 36W load. Maintain airflow and stop only for abnormal heat, smell or instability.
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 one phone fast-charges and the other does not, swap the cables and ports. Because the outputs are equivalent, the result helps isolate cable or device protocol support.

Product-specific FAQ
What is the maximum output?
Up to 18W per USB-A port and 36W total when both ports are used with compatible devices.
How does power change when more than one device is connected?
Both ports can maintain up to 18W simultaneously, producing the documented 18W + 18W = 36W total.
Can it charge a laptop?
No. It has no USB-C PD output and is intended for phones, tablets and portable accessories rather than laptops.
Which port should I use first?
Either port can be used first because the two USB-A outputs have the same documented profiles and ceiling.
Does it support fast charging?
Yes, for devices supporting QC 3.0/2.0, FCP, AFC or another listed USB-A charging family. It does not support PD or PPS.
Will it work in a 24V truck or commercial vehicle?
It is specified for compatible 12–24V DC vehicle accessory sockets.
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 10144 charger and one user manual are listed. A charging cable is not promised for the exact India package.
How do I confirm this is the correct model?
Match SKU 10144 and, where shown, model 10144 on the product or retail label before relying on this page's port and power tables.
