UGREEN Nexode 55910B 145W 4-Output Retractable Car Charger
Overview
UGREEN 55910B turns one compatible 12–24V vehicle outlet into four USB charging connections. USB-C2 can provide up to 100W by itself to a compatible USB PD device using a suitable detachable cable. The built-in USB-C cable reaches up to 60W alone and retracts into the body. USB-C1 and USB-A can each reach up to 30W alone. The advertised 145W is a shared two-device ceiling—not a single-port figure—and every additional connection changes the available allocation.
What it does well.
Key features
Port map and connector roles
Port labels matter: USB-C2 is the only 100W connector. The integrated cable is a separate 60W output, and USB-C1 should not be mistaken for USB-C2.
Charging protocols and speed logic
The USB-C outputs support USB PD 3.0 and PPS as well as common QC, SCP, FCP, AFC, Apple 5V/2.4A and BC1.2 modes, with port-specific limits. USB-A supports SCP, QC 3.0, FCP, AFC, Apple 5V/2.4A and BC1.2. Protocol support means the charger can negotiate those families; it does not guarantee every proprietary brand label or maximum rate.
Compatible devices and systems
Compatibility rule: A USB-C connector does not by itself prove 100W support. Check the device input, cable rating and selected port, then account for sharing.
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
Keep the retractable connector away from seat rails, doors, cup-holder liquids and sharp sideways bends. The fixed lead is not listed as user-replaceable, so careful handling directly affects service life.
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 145W from a single connector; the strongest individual output is USB-C2 at up to 100W.
- Do not buy it expecting all four connections to retain 100W, 60W, 30W and 30W simultaneously.
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 USB-C2 for the highest-demand device and reserve the integrated cable for the second priority device.
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 pull the retractable lead sideways, force it beyond its travel or allow uncontrolled retraction.
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.
- At the maximum published input the vehicle outlet can be heavily loaded; confirm the outlet and fuse rating in the vehicle manual.
Troubleshooting
Useful diagnostic: If a laptop reports slow charging, test USB-C2 alone with a known 5A cable. If performance improves, the prior limit was probably cable capability or shared-port allocation.
At a glance.
- USB-C2 alone
- Up to 100W with a compatible USB PD device and suitable 5A cable.
- Integrated cable alone
- Up to 60W.
- USB-C1 alone
- Up to 30W.
- USB-A alone
- Up to 30W with a compatible fast-charge profile.
- USB-C2 + integrated cable
- Up to 100W + 45W = 145W total.
- All four outputs
- USB-C2 up to 65W + integrated cable up to 45W + USB-C1 7.5W + USB-A 7.5W.
- In the box
- Confirm that the SKU is 55910B/55910.
Check that the vehicle socket is rated for the intended load.
Bring a suitable 5A USB-C cable if you intend to use USB-C2 near 100W.
Remember that the integrated cable is USB-C and cannot be swapped for Lightning or another connector.
Confirmed package: 1 × UGREEN 55910B car charger with permanently integrated retractable USB-C cable and 1 × user manual. A separate detachable USB-C cable is not listed as included.
