Xiaomi 65W Power Adapter Launched in China?

Yes, Xiaomi launched its 65W USB-C power adapter in China, initially as part of the Mi 10 Pro smartphone launch in February 2020 and later sold separately. This compact GaN (gallium nitride) charger supports fast charging for Xiaomi phones and can also charge laptops, tablets, and other USB-C devices. Below, we break down the adapter’s specs, compatibility, safety, and how it compares to other chargers.

Background: The GaN Revolution

Xiaomi’s 65W adapter is notable for using gallium nitride (GaN) instead of traditional silicon for its power transistors. GaN allows higher switching frequencies and better thermal efficiency, so chargers can be much smaller and lighter than silicon-based ones at the same wattage. Xiaomi was among the first major phone brands to adopt GaN in a mass-market charger, following similar moves by RAVPower and Anker. The adapter’s dimensions are roughly 30.8 x 30.8 x 56.3 mm (about the size of a large cube), and it weighs around 82 grams, making it significantly more portable than older 65W laptop bricks.

Specifications and Compatibility

The Xiaomi 65W GaN charger has a single USB-C port and supports a wide range of charging protocols:

• USB Power Delivery (PD) 3.0 – up to 65W, ideal for laptops, tablets, and Nintendo Switch.
• Qualcomm Quick Charge 3.0/4+ – for compatible Android phones.
• Xiaomi proprietary fast charging – up to 50W on Mi 10 Pro (via a special cable and protocol).
• PPS (Programmable Power Supply) – allows dynamic voltage adjustment for newer Samsung and Xiaomi devices.

The adapter outputs 5V/3A, 9V/3A, 12V/3A, 15V/3A, and 20V/3.25A, covering most USB-C devices. It can charge a MacBook Air (30W) at full speed, a MacBook Pro 13 (61W) at full speed, and a 15-inch MacBook Pro (87W) at about 75% speed. For phones, it can fast-charge an iPhone (20W), a Samsung Galaxy (45W), and Xiaomi’s own flagships at their maximum supported rates.

How It Works: GaN and Fast Charging

GaN chargers convert AC power from the wall to DC power for your device. The key advantage is that GaN transistors can switch on and off much faster than silicon, reducing energy loss and heat. This allows the charger to be smaller while delivering the same or higher wattage. The Xiaomi adapter uses a single-port design with a foldable plug (in the Chinese version), which is convenient for travel. It also includes over-current, over-voltage, and short-circuit protection, as required by Chinese safety standards (CCC certification).

How to Choose the Right Charger for Your Device

When selecting a 65W charger, consider the following:

• Ports: Single USB-C is fine for one device; multi-port chargers (e.g., 2 USB-C + 1 USB-A) are better for travel.
• Protocol support: Ensure it supports PD 3.0 and PPS for broad compatibility with laptops and phones.
• Size and weight: GaN chargers are typically 30-50% smaller than older silicon ones.
• Cable: For 65W output, you need a USB-C to USB-C cable that supports 5A (100W) – many included cables are 3A (60W) only.

For Xiaomi phones with proprietary fast charging (like 50W or 67W), you must use an official Xiaomi charger and cable to get the full speed. A generic 65W PD charger will likely cap at 27W or 18W.

Common Problems and Misconceptions

One common misconception is that a 65W charger will always deliver 65W. In reality, the charger only provides what the device requests. A phone might draw 18W, a laptop 45W, and only a high-power laptop will use the full 65W. Another issue is that the Chinese version of this adapter has a two-pin plug without grounding, which is normal for low-power chargers but may feel loose in some outlets. Also, some users report that the adapter gets warm during heavy use – this is normal for GaN chargers, but it should not be hot to the touch. If it is, stop using it and check for damage.

Comparison with Other 65W Chargers

Compared to Apple’s 61W USB-C charger (which is silicon-based and much larger), the Xiaomi GaN adapter is a clear winner in size and price. Against Anker’s 65W GaN charger (which has two USB-C ports and one USB-A), the Xiaomi is smaller but has only one port. The Xiaomi also supports PPS, which Anker’s older model does not. In terms of build quality, Xiaomi’s charger feels solid, but the foldable plug is slightly wobbly on some units. Overall, it is one of the most compact 65W chargers available, though multi-port alternatives are more versatile for users with multiple devices.

Cost and Availability

In China, the Xiaomi 65W GaN charger launched with a retail price of about 149 CNY (roughly $21 USD). It quickly sold out due to high demand, and third-party sellers on platforms like Taobao and JD.com often marked it up. Outside China, it was not officially released, but it can be found on AliExpress and other import sites, usually for $25-$35. Shipping from China may take 2-4 weeks. The charger comes with a 1-meter USB-C to USB-C cable, which is rated for 100W (5A) – a nice bonus.

Safety and Certification

The adapter is certified by CCC (China Compulsory Certification) and meets the GB 4943.1 safety standard for information technology equipment. It has built-in protections against over-current, over-voltage, over-temperature, and short-circuit. However, because it is not sold in many Western markets, it lacks UL, CE, or FCC markings. That does not mean it is unsafe, but it may not be approved for sale in some regions. If you import one, ensure your outlet voltage matches (100-240V AC, 50/60Hz), which it supports. Avoid using the charger if it is damaged, and do not cover it while in use, as it needs airflow to dissipate heat.

Frequently Asked Questions

Can I use the Xiaomi 65W charger with my MacBook Pro?

Yes, the charger supports USB PD 3.0, so it can charge any MacBook that uses USB-C. For a 13-inch MacBook Pro (61W), it provides full speed. For a 16-inch MacBook Pro (96W), it will charge at about 65W, which is slower but still functional.

Does the Xiaomi 65W charger support Samsung fast charging?

Yes, it supports PPS, which Samsung phones use for their Super Fast Charging (up to 45W on Galaxy S20 Ultra and newer). It also supports Quick Charge 3.0/4+ for older Samsung models.

Is the Xiaomi 65W charger safe to use with my iPhone?

Yes, it is safe. The charger uses standard USB PD, which iPhones support. It will charge an iPhone at up to 20W (the maximum the iPhone can take), and the charger’s protections ensure safe operation.

Why does my Xiaomi phone only charge at 18W with this charger?

If your Xiaomi phone does not support the proprietary fast charging protocol (e.g., Mi 10 Pro’s 50W), it will fall back to standard PD, which is typically 18W or 27W. To get the full speed, you need the original Xiaomi charger and cable that support the proprietary protocol.

Can I use the Xiaomi 65W charger to charge my Nintendo Switch?

Yes, the Switch supports USB PD, and this charger can power it in docked mode (which requires 39W) or charge it in handheld mode. It is a good alternative to the official Switch charger.

Is the Xiaomi 65W charger compatible with 100-240V outlets?

Yes, it has a universal input of 100-240V AC, 50/60Hz, so you can use it worldwide with a simple plug adapter (the Chinese version has a two-pin flat plug).
