Performance and Charging Speeds: Benchmarked Data
Anker’s 20W USB-C charger leverages Power Delivery (PD) 3.0 technology, which dynamically adjusts voltage and current to optimize charging speed and efficiency. Here’s how it performs with Apple’s latest devices:
iPhone 16 Series Charging (Tested with iPhone 16 Pro Max):
- 0% to 50% in 25 minutes (Apple’s official claim; Anker matches this)
- 0% to 80% in 45 minutes
- Full charge (0–100%) in approximately 1 hour 45 minutes
These times were verified using Anritsu power analyzers and controlled lab conditions (room temperature: 22°C). The charger maintains a stable 20W output during the initial fast-charge phase before tapering down to prevent battery stress.
iPad Pro (M4, 2024) Charging:
- Delivers up to 20W charging (iPad Pro supports up to 30W, so not at full speed)
- Charges from 0 to 50% in about 60 minutes
- Ideal for light use and overnight charging
Cross-Device Compatibility:
- Samsung Galaxy S24 Ultra: Charges at 25W (device supports higher, but Anker caps at 20W)
- Google Pixel 8 Pro: 20W PD charging, 0–50% in 30 minutes
- MacBook Air M2: Can charge at 20W—slower than Apple’s 30W+ chargers but sufficient for light tasks or top-ups
While not the fastest charger for laptops, it’s excellent for smartphones and tablets.
Why 20W? The Science Behind Fast Charging
Apple officially supports 20W USB-C PD fast charging for all iPhone 15 and iPhone 16 models. Despite higher-wattage chargers (30W, 65W, 100W) being available, iPhones do not charge faster beyond 20W due to internal power management limitations.
Anker’s 20W charger is optimized for this sweet spot, avoiding unnecessary power draw, excess heat, and energy waste. Independent tests show that using a 65W charger with an iPhone results in only marginal speed gains (1–2 minutes) while increasing thermal output by 15–20%.
By focusing on 20W, Anker ensures:
- Maximum efficiency
- Lower heat generation
- Longer device and battery lifespan
- Reduced energy consumption
This makes the Anker 20W charger not only fast but also eco-friendly and battery-conscious.
Build Quality and Design
Anker has refined the design of its compact chargers with a minimalist, modern aesthetic. The white finish matches Apple’s iPhone 16 color palette, making it a seamless addition to any Apple-centric setup.
- Material: Flame-retardant polycarbonate (UL 94 V-0 certified)
- Size: One of the smallest 20W USB-C chargers on the market—30% smaller than Apple’s 20W charger
- Foldable Plug: Integrated US prongs (non-removable), ideal for travel
- Heat Dissipation: Multi-layer internal shielding and thermal pads reduce operating temperature by up to 10°C compared to budget chargers
In stress tests, the charger operated at 42°C under continuous 20W load for 1 hour, well below the 60°C safety threshold. This ensures safe, long-term use even in warm environments.
Included Cables: What You Need to Know
The bundle includes two 3.3 ft (1m) USB-C to USB-C cables with the following specs:
- Power Delivery: Up to 60W (supports 20W iPhone charging and 30W iPad charging)
- Data Transfer: USB 2.0 speeds (up to 480 Mbps)
- Durability: Reinforced stress points, 10,000+ bend lifespan
- Connector Material: Nickel-plated for corrosion resistance
These cables are MFi-certified (Made for iPhone), meaning they are tested and approved by Apple for safe use with iPhone 16 and other USB-C Apple devices. They also support fast charging for Samsung, Google, and other USB-C devices.
Anker uses e-marker chips in the cables to ensure stable high-power delivery and prevent overheating or voltage drops—critical for safety and performance.
Safety and Protection Features
Anker integrates eight layers of protection into its charging technology:
- Overvoltage Protection (OVP)
- Overcurrent Protection (OCP)
- Overtemperature Protection (OTP)
- Short-Circuit Protection (SCP)
- Electromagnetic Interference (EMI) Shielding
- Surge Protection
- Foreign Object Detection (FOD)
- Battery Temperature Monitoring
These features ensure that your iPhone 16 or iPad Pro is protected from power spikes, overheating, and electrical faults. In third-party lab tests, the Anker charger successfully blocked 99.8% of voltage surges and shut down automatically when internal temperatures exceeded 55°C.
Additionally, Anker uses GaN (Gallium Nitride) technology in its internal circuitry. GaN is more efficient than traditional silicon, allowing for smaller size, less heat, and higher efficiency (up to 90% energy conversion rate).
Compatibility: Which Devices Work?
The Anker 20W USB-C charger is universally compatible with a wide range of devices:
Apple Devices:
- iPhone 16, 16 Plus, 16 Pro, 16 Pro Max (USB-C)
- iPhone 15, 15 Plus, 15 Pro, 15 Pro Max
- iPad Pro (11” & 13”, M4, 2024)
- iPad Air (5th gen)
