• USB-A to Micro-USB
• Other compatible USB charging cables

Charging cables are not included unless specifically stated.

USB-C Power Delivery

The USB-C port supports USB Power Delivery for compatible devices.

USB Power Delivery allows the charger and connected device to negotiate an appropriate charging profile. Depending on the device, cable, battery condition, and charging state, this may provide faster charging than a basic 5V USB adapter.

USB-C Power Delivery may be suitable for compatible:

• Apple iPhone models
• Samsung Galaxy smartphones
• Google Pixel smartphones
• Motorola smartphones
• USB-C tablets
• Wireless earbuds
• Portable game accessories
• Power banks
• Other small USB-C devices

Fast-charging performance depends on the connected device supporting USB Power Delivery and the use of a compatible cable.

USB-A Charging

The USB-A port provides compatibility with a wide range of traditional charging cables and accessories.

It may be used with compatible:

• Smartphones
• Wireless earbuds
• Smartwatches
• Fitness trackers
• Power banks
• Bluetooth speakers
• E-readers
• Portable accessories
• Older Micro-USB devices
• Lightning-equipped Apple devices
• Other USB-powered products

USB-A charging speed depends on:

• Device compatibility
• Cable quality
• Supported charging protocol
• Battery condition
• Temperature
• Whether the second port is in use

Quick Charge Compatibility

The adapter is described by AmpSentrix as compatible with Quick Charge 2.0.

Quick Charge performance requires:

• A compatible device
• A suitable charging cable
• Correct charging negotiation
• Acceptable device temperature
• A battery capable of receiving the negotiated power

A device that does not support Quick Charge will normally charge using a compatible standard USB power profile.

Quick Charge branding and implementation may vary among device manufacturers.

Charging Two Devices Simultaneously

Both output ports may be used at the same time.

When two devices are connected, the charger’s available output may be distributed between the ports. Each device may therefore charge more slowly than when it is the only connected device.

Simultaneous charging performance depends on:

• Total available charger output
• Power requested by each device
• Cable capability
• Device charging protocol
• Battery level
• Temperature
• Charging-management circuitry

The 20W rating should be treated as the adapter’s maximum combined output, not as 20W from each port simultaneously.

For the fastest supported charging of one compatible device, use only the required port and a suitable high-quality cable.

Compatible Apple Devices

The adapter may be used with compatible Apple products, including selected:

• iPhone models
• iPad models with modest charging requirements
• AirPods and compatible charging cases
• Apple Watch charging cables
• MagSafe chargers within the adapter’s supported output
• Other USB-powered Apple accessories

A USB-C to Lightning cable is required for USB-C Power Delivery charging of Lightning-equipped iPhone models.

A USB-C to USB-C cable is required for compatible USB-C iPhone and iPad models.

Apple fast-charging speed depends on the model, cable, battery level, temperature, and software-controlled charging behaviour.

Compatible Android Devices

The adapter may be suitable for compatible Android devices from brands such as:

• Samsung
• Google
• Motorola
• OnePlus
• LG
• Sony
• Nokia
• TCL
• ZTE
• Other manufacturers

Charging speed depends on whether the device supports:

• USB Power Delivery
• Quick Charge 2.0
• Standard USB charging
• Another manufacturer-specific charging protocol

Devices requiring proprietary high-wattage charging systems may charge at a lower rate when connected to this adapter.

Tablet Compatibility

The adapter may charge compatible small or medium tablets, but it is not intended to replace a high-wattage laptop or tablet power supply.

Charging may be slower when:

• The tablet normally uses a charger above 20W
• The tablet is being used heavily while charging
• Screen brightness is high
• Games or demanding applications are running
• Two devices are connected simultaneously

Some larger tablets may charge slowly, maintain their battery level, or display a slow-charging notification.

Laptop Compatibility Notice

This 20W adapter is primarily intended for smartphones and smaller USB-powered devices.

It is generally not recommended as the primary charger for laptops that require:

• 30W
• 45W
• 60W
• 65W
• 96W
• 100W
• Another higher charging level

Some low-power USB-C laptops may recognize the adapter but charge slowly or only while asleep or powered off.

Consult the laptop manufacturer’s recommended power-adapter specification before use.

Cable Compatibility

Charging performance depends heavily on the connected cable.

Use a cable that:

• Supports the required connector type
• Supports the intended charging protocol
• Is rated for the necessary current and voltage
• Has no damaged insulation
• Has no bent or corroded contacts
• Fits securely in both the adapter and device
• Is from a reputable manufacturer

A poor-quality, damaged, or charge-only cable may cause:

• Slow charging
• Intermittent charging
• Excessive heat
• Charging disconnection
• Failed Power Delivery negotiation
• Data-transfer limitations
• Connector damage

The charger does not include a cable unless specifically stated.

Charging-Speed Notice

The adapter does not force a connected device to accept 20W.

Actual charging power is controlled by the connected device and may vary with:

• Battery percentage
• Battery health
• Device model
• Charging protocol
• Cable capability
• Device temperature
• Ambient temperature
• Software settings
• Optimized charging features
• Background use
• Whether both ports are occupied

Many devices reduce charging speed as the battery approaches full capacity. This is normal charging-management behaviour.

Heat and Temperature Notice

Some warmth during charging is normal, particularly when:

• Fast charging is active
• The battery level is low
• The device is being used while charging
• Two devices are connected
• The ambient temperature is high
• The charger is covered or poorly ventilated

Stop using the adapter if it becomes:
