UGREEN 50875 24W Dual USB-A Car Charger
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.
What it does well.
Key features
Port map and connector roles
Port labels matter: Both outputs are USB-A and have the same stated ceiling. Choose by cable routing rather than power priority.
Charging protocols and speed logic
The charger uses intelligent 5V current identification up to 2.4A per output, but this 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.
Compatible devices and systems
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.

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 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 total is 5V × 4.8A = 24W.
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.
Troubleshooting
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.
At a glance.
- 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.
- In the box
- Confirm SKU 50875.
Confirm that both intended cables terminate in USB-A at the charger end.
Accept standard 5V charging rather than PD/QC performance.
Check whether the vehicle socket remains powered when parked.
Confirmed item: 1 × UGREEN 50875 dual-USB-A car charger. No charging cable is shown or listed as part of the live India package, so bring the appropriate USB-A cable for each device.
