Xiaomi Redmi Note 4X charger type, Micro-USB 5V 2A charging specs

User question

What charger does Xiaomi Redmi Note 4X use?

Artificial Intelligence Response

Direct answer to the question

The Xiaomi Redmi Note 4X uses a standard Micro-USB charger:

• Phone connector: Micro-USB, not USB-C
• Original/recommended charger output: 5 V / 2 A
• Charging power: about 10 W
• Cable: USB-A to Micro-USB
• Fast charging: No practical high-voltage fast charging support; use it as a normal 5 V charger device

So, if you need a replacement, buy a good-quality 5 V / 2 A USB charger with a USB-A to Micro-USB cable.

Detailed problem analysis

The Redmi Note 4X charges through a Micro-USB 2.0 port. This was common on Android phones from that period, before USB-C became standard on most Xiaomi models.

The expected charging specification is:

Item	Specification
Connector	Micro-USB
Charger type	USB-A wall adapter
Output voltage	5 V DC
Output current	2 A recommended
Power	10 W
Cable	USB-A to Micro-USB

Although some versions of the Redmi Note 4X use the Qualcomm Snapdragon 625 platform, which can theoretically support Qualcomm Quick Charge, the Redmi Note 4X is generally treated as a standard 5 V / 2 A charging phone. In practice, it does not benefit meaningfully from higher-voltage fast chargers such as 9 V or 12 V Quick Charge modes.

Practical guidelines

You can use:

• An original Xiaomi 5 V / 2 A charger
• Any reputable branded 5 V / 2 A USB charger
• A charger rated above 2 A, for example 5 V / 2.4 A, because the phone only draws the current it needs
• A modern fast charger, provided it supports standard 5 V USB output

Avoid:

• Very cheap unbranded chargers
• Damaged Micro-USB cables
• Old 5 V / 1 A chargers if you want normal charging speed
• Loose or worn Micro-USB cables, which are common causes of slow or intermittent charging

Supporting explanations and details

A charger’s current rating is its maximum available current, not the current forced into the phone. For example, a 5 V / 3 A charger will not push 3 A into the Redmi Note 4X. The phone’s internal charging circuit controls how much current is drawn.

The important part is the voltage. A normal USB charger provides 5 V DC, which is what the Redmi Note 4X expects. Modern USB-C PD or Quick Charge adapters also normally fall back to 5 V when connected through a compatible USB-A to Micro-USB cable or basic charging mode.

Brief summary

Use a 5 V / 2 A Micro-USB charger for the Xiaomi Redmi Note 4X. The correct cable is USB-A to Micro-USB. A higher-wattage charger is usually safe, but the phone will still charge at around its normal 10 W rate.
