UGREEN 10144 36W Dual USB-A QC 3.0 Car Charger
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.
What it does well.
Key features
Port map and connector roles
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.
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.
Compatible devices and systems
Compatibility rule: USB-A connector fit does not guarantee QC 3.0. Unsupported devices fall back to a mutually supported lower profile.
Use scenarios
Setup and usability guidance
No software required: The charger is plug-and-play; correct socket fit, port choice and cable routing are the important setup decisions.
- 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.
Everyday usability and care
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
Stop-use trigger: Disconnect immediately if you notice arcing, smoke, a burning smell, melted plastic, visible deformation or repeated unexplained power loss.
- 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.
Troubleshooting
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.
At a glance.
- One USB-A port
- Up to 18W.
- Two USB-A ports together
- Up to 18W + 18W = 36W total.
- In the box
- Confirm SKU 10144.
Confirm both intended cables use USB-A at the charger end.
Choose a different model if USB-C PD/PPS is required.
Verify that the intended devices support useful USB-A fast-charge profiles.
