Overview
UGREEN 50875 is deliberately straightforward: it converts a compatible 12–24V vehicle outlet into two 5V USB-A charging connections. Each port can provide up to 5V/2.4A, or 12W, and the two-port total is up to 5V/4.8A, or 24W. It does not support USB Power Delivery, PPS or Qualcomm Quick Charge, so devices that require those protocols will use a standard compatible 5V charging mode instead of showing their branded fast-charge status.
Best-fit summary: Drivers with two USB-A cables who want dependable 5V charging for phones, tablets, navigation devices and small accessories rather than modern USB-C PD performance.
Key features
Two equal ports
Each USB-A port can provide up to 5V/2.4A; there is no “laptop” or priority connector.
24W means total
Two ports together provide up to 5V/4.8A, equal to 24W.
Protocol expectation
It does not advertise PD or QC. A phone can still charge, but its fast-charge label may not appear.
Port map and connector roles
USB-A port 1
Standard 5V charging, up to 2.4A / 12W.
USB-A port 2
Standard 5V charging, up to 2.4A / 12W.
Port labels matter: Both outputs are USB-A and have the same stated ceiling. Choose by cable routing rather than power priority.
Exact power allocation
| One USB-A port | Up to 5V/2.4A = 12W. |
|---|---|
| Two USB-A ports together | Up to 5V/4.8A = 24W total, with up to 2.4A available to each port. |
Read the table before buying: The correct electrical statement is 4.8A total, not 4.8W. It is a fixed 5V charger and should not be marketed as a PD/QC fast charger.
Charging protocols and speed logic
The charger uses intelligent 5V current identification up to 2.4A per output, but the exact product copy explicitly says it does not support PD or QC protocols. Devices remain safe because they draw the current they accept; however, protocol-dependent fast charging will fall back to a standard 5V mode.
No USB-C port
USB-C devices require a sound USB-A-to-USB-C cable and remain limited to this charger’s 5V behaviour.
No PD/PPS
It cannot provide 9V, 12V or variable-voltage USB-C fast-charge profiles.
No QC claim
QC-dependent Android phones can charge at a compatible fallback rate but should not be promised their QC speed.
Compatible devices and systems
Phones and tablets
Works with iPhone, iPad, Galaxy, Pixel and other devices when paired with the correct USB-A charging cable; actual rate is limited to a 5V profile.
Navigation and accessories
Well suited to GPS units, dash cameras, earbuds, watches, speakers, e-readers and other modest 5V loads.
Vehicles
Designed for compatible 12V or 24V accessory sockets. Mechanical fit and socket condition remain vehicle-specific.
Not a laptop charger
It is not suitable for USB-C laptops that require PD negotiation or more than a standard 5V input.
Compatibility rule: A cable fitting the device does not add PD or QC. Choose this model only when standard 5V USB-A charging meets the requirement.
Use scenarios
Two-phone commute
Charge two ordinary USB-A-connected phones at the same time, up to 12W per port.
Navigation plus passenger
Keep a navigation phone powered and give the second USB-A output to a passenger.
Dash camera plus phone
Power a modest 5V dash camera and charge a phone if both loads remain within the stated total.
Legacy cable kit
Continue using established USB-A-to-Lightning, Micro-USB or USB-C cables without replacing the car charger.
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 compact PC housing sits low in many sockets. Remove it by holding the charger body; do not pull a connected cable to extract it.
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 PD, PPS, Quick Charge voltage profiles or a USB-C receptacle.
- Do not buy it for a USB-C laptop, handheld PC or phone that needs protocol-dependent high-voltage charging.
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 USB-A cable with adequate conductors; very thin or worn leads can cause voltage drop and slow charging.
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 describe 4.8A as 4.8W—the verified total is 5V × 4.8A = 24W.
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.
- Some live marketplace-style artwork has a “4.8W” typo. The exact product copy and electrical calculation support 4.8A total / 24W.
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 a phone says “slow charger,” test a shorter known-good USB-A cable. If the phone specifically requires PD or QC for fast charging, the fallback rate is expected.
