Overview
UGREEN 10216 / CD161 is a dual-USB-A wall charger built around two independent 18W Quick Charge 3.0 outputs. Each port can negotiate 5V/3A, 9V/2A or 12V/1.5A, and both can deliver up to 18W simultaneously for a true 36W total. It is suited to devices and cables that still use a USB-A charger end. It does not contain USB-C, USB Power Delivery or PPS, so a modern USB-C phone may charge only through a suitable USB-A-to-device cable and within the older protocol set.
Best-fit summary: Two phones, tablets or accessories that already use USB-A fast-charge cables and do not require USB-C PD or PPS.
Key features
Independent 18W outputs
Unlike many shared-budget dual chargers, both USB-A ports retain an 18W ceiling together.
QC 3.0 negotiation
Compatible devices can select 5V, 9V or 12V profiles; unsupported devices fall back to a common safe mode.
Legacy-cable practicality
A useful replacement when existing device cables have USB-A charger ends.
Port map and connector roles
USB-A port 1
Up to 18W: 5V/3A, 9V/2A or 12V/1.5A with a compatible QC/AFC/FCP-family device and cable.
USB-A port 2
Same independent 18W ceiling and fixed profiles as port 1.
No USB-C receptacle
USB-C devices require a suitable USB-A-to-USB-C cable and cannot use USB Power Delivery or PPS through this charger.
Fixed mains plug
EU 2-pin; 100–240V electrical input does not guarantee secure fit in every Indian socket.
Port labels matter: The two orange receptacles are USB-A power outputs. Neither is USB-C, and neither transfers data.
Exact power allocation
| Port 1 alone | Up to 18W: 5V/3A, 9V/2A or 12V/1.5A. |
|---|---|
| Port 2 alone | Up to 18W with the same supported profiles. |
| Both ports together | Up to 18W + 18W = 36W total. |
| Non-QC device | Negotiates a compatible fallback, commonly 5V; the device decides the accepted current. |
| USB-C phone via A-to-C cable | Can receive only a profile supported through USB-A; no PD or PPS session is possible. |
Read this before connecting several devices: 36W is the combined two-port total, but it is genuinely documented as 18W + 18W—not 36W from one port.
Charging protocols and speed logic
Official UGREEN sources list Quick Charge 3.0 and regional AFC/FCP compatibility for the two USB-A outputs. The fixed voltage/current profiles are 5V/3A, 9V/2A and 12V/1.5A. There is no USB Power Delivery, PD 3.0, PD 3.1 or PPS because those modern USB-C negotiation modes are not present on this USB-A-only charger.
QC device
A compatible phone can request 9V or 12V within the 18W ceiling.
Standard fallback
An unsupported device should negotiate a lower common USB charging mode rather than being forced to 12V.
No PD conversion
An A-to-C cable changes the connector at the device end; it does not turn the charger into USB-C PD.
Compatible devices and systems
QC-era Android phones
Compatible Galaxy, Xperia, Redmi, Huawei and other models can use supported QC/AFC/FCP modes when paired with the correct USB-A cable.
iPhone and iPad
Can charge with an appropriate USB-A-to-Lightning cable, generally within Apple USB-A charging behaviour rather than USB-C PD.
USB-C phones and accessories
Can use a suitable USB-A-to-USB-C cable, but maximum branded fast-charge modes may not be available.
Not for USB-C laptops
Most USB-C notebooks require Power Delivery at 30W, 45W, 65W or more; this 18W USB-A path is not an appropriate laptop charger.
Compatibility rule: Choose it for USB-A cable ecosystems. If the device specifically asks for USB-C PD or PPS, choose a USB-C charger instead.
Use scenarios
Two-phone bedside
Charge two compatible phones with separate USB-A cables while preserving an 18W ceiling for each port.
Family legacy-cable kit
Reuse two working USB-A phone or accessory cables from older devices.
Office accessory point
Power a phone and a USB-charged accessory without occupying a laptop’s USB port.
Travel voltage range
Use across common 100–240V mains systems only after confirming the EU pins fit the local socket or rated adapter securely.
Setup and usability guidance
- Read the product label and confirm that the mains-input range, fixed plug and wall socket are compatible before connecting power.
- This regional SKU uses fixed EU 2-pin pins. If the socket does not grip them securely, use a properly rated certified adapter rather than forcing or balancing the charger.
- Connect the charger to a sound, dry wall socket; connect a correctly rated cable to the intended USB output; then connect the device.
- For the highest-power session, begin with the strongest documented USB-C output and one device. Add other devices only after checking the sharing table.
- Unplug by holding the charger body. Do not remove it by pulling a charging cable.
- Connect one known-compatible QC device first and verify its fast-charge indicator before adding the second device.
Setup principle: Start with one device on the strongest intended output, then add lower-priority devices.
Everyday usability and care
Equal port roles
Either USB-A output can serve the priority device because both have the same 18W ceiling.
Cable condition
Worn USB-A contacts or thin cables can cause voltage drop and slow charging even when the charger is healthy.
Simple two-device logic
Both ports retain their rated 18W ceiling, so there is no complex high/low port hierarchy.
Travel distinction
Universal voltage concerns electrical input; a separate rated plug adapter may still be needed for physical fit.
Keep the two USB-A ports free of lint and conductive debris. Disconnect mains power before cleaning and never insert metal tools into a receptacle.
What this product does
- Converts 100–240V AC mains power into negotiated low-voltage USB charging outputs for compatible electronics.
- Selects a mutually supported voltage and current with the connected device; there is no manual voltage switch.
- Redistributes a finite total power budget when more than one output is occupied.
- Works without an app, account, driver, Wi-Fi or Bluetooth connection.
- Provides a verified simultaneous 18W + 18W arrangement.
What this product does not do
- It is not a voltage converter for AC appliances and it does not create a household AC outlet.
- Its USB connectors are charging outputs, not file-transfer, video, networking or docking ports.
- It cannot force a device to accept a wattage or fast-charge protocol that the device and cable do not support.
- It cannot keep every port at its single-port maximum when several devices share the charger.
- It does not support USB-C PD, PPS or laptop-class charging.
What to do
- Use sound cables rated for the current and power requested by the device.
- Keep the charger uncovered and exposed to air during high-power charging.
- Place the highest-demand device on the strongest documented output.
- Expect a brief charging reset when a connection changes and power is renegotiated.
- Disconnect mains power before cleaning and use only a dry, soft cloth.
- Use two separate sound USB-A cables rather than a multi-headed splitter cable.
What not to do
- Do not use a loose, scorched, cracked, wet or mechanically damaged wall socket, adapter, cable or charger.
- Do not cover the charger with bedding, clothing or other insulating material.
- Do not force EU pins into a socket that does not accept them securely.
- Do not assume connector shape alone proves protocol or wattage compatibility.
- Do not disassemble the housing or continue use after arcing, smoke, odour, deformation or repeated unexplained shutdown.
- Do not assume a USB-A-to-USB-C cable unlocks USB-C Power Delivery.
Warnings and limitations
- The printed wattage is a maximum under defined conditions, not a promise that every device will draw that power.
- Charging normally slows as a battery fills, warms up or applies its own battery-health controls.
- Some warmth is normal at high load. Excessive heat, smell, noise, deformation or cycling requires immediate disconnection.
- This charger is intended for dry indoor use and is not documented as waterproof.
- A plug adapter changes only physical fit; it does not repair a loose socket or create a new charging protocol.
- No USB cable or India plug adapter is listed in the exact package.
Stop-use trigger: Disconnect immediately for arcing, smoke, burning smell, melted material, visible deformation or repeated unexplained power loss.
Troubleshooting
No QC indicator
Confirm that the device and cable both support the relevant USB-A quick-charge mode, then test one port and device alone.
One port is slow
Swap the two cables and ports. If the symptom follows the cable or device, the charger is unlikely to be the limiting component.
Plug feels loose
Disconnect immediately and use a sound compatible socket or properly rated certified adapter; do not prop the charger in place.
USB-C phone charges slowly
The phone may expect PD/PPS, which this USB-A-only product cannot provide. Use its recommended USB-C charger for the intended speed.
Useful diagnostic: Test each USB-A port separately with the same known-good QC device and cable, then test both together. This distinguishes a port fault from cable or protocol mismatch.
