Charging power for Xiaomi Redmi: how many watts does your model need (2020–2026)

Xiaomi Redmi smartphones are known for their price-performance ratio, but even budget models today support fast charging.The problem is that the manufacturer often doesn't put the original charger in the box - especially in recent years. As a result, users are faced with the question: how many watts should be charged for Redmi, so as not to burn the phone and not to wait forever?

In this article, we’ll break down the power of the chargers for all of the current Redmi models (2020–2026), explain why it’s important to use the right adapter, and give you a selection of tips: whether you can charge the Redmi Note 12 with a charge from the Redmi 9A, what is Quick Charge and Pump Express, and why cheap Chinese adapters can reduce the life of your battery by 30%.

Spoiler: Redmi Note 13 Pro+ supports 120W charging, but only with the original adapter – third-party power supplies even at 65W may not give full speed.

Why charging power is important for Xiaomi Redmi

The power of the charger is measured in watts (W) and determines how fast your smartphone will charge, but it’s not just a matter of speed — choosing the wrong adapter can lead to:

• 🔥 Battery overheating – if power is too high for the smartphone’s power controller.
• 🐢 Slow charging – if the adapter is weaker than the phone supports (e.g, 5W model 33W).
• ⚡ Damage to the port USB-C — Cheap charging without protection can cause voltage surges.
• 📉 Reduce battery life – Constant charging at maximum power accelerates degradation of lithium-ion cells.

Xiaomi is using several fast charging technologies:

• Quick Charge 3.0/4+ (Qualcomm) – up to 27W, compatible with most Redmi on Snapdragon.
• Pump Express (MediaTek) - up to 20W, used in models on the Helio G-series.
• Mi Turbo Charge is Xiaomi’s proprietary technology, up to 120W in top-end models.

Important: The phone adjusts the power consumption itself – if you plug the Redmi 10 (18W) into a 67W charge, it will only take 18W. But the reverse situation (a weak adapter for a powerful phone) will lead to slow charging.

Charging power table for all Xiaomi Redmi (2020–2026)

Below is the maximum supported charging power for each model. Note: some phones support two speeds – for example, the Redmi Note 11 Pro+ can charge at 67W or 120W depending on the configuration.

⚠️ Note: In Europe, Xiaomi has not put chargers in the box since 2022 due to environmental regulations. EU, Check the supported power in the table above – most likely, you will need to buy an adapter separately.

How to find out what kind of charger your Redmi needs

If you haven’t found your model in the table or are in doubt about the choice, there are several ways to determine the optimal power:

1. Use the AIDA64 app: Install from Google Play. Go to Battery → Charge level. Connect charging – the app will show the current power (in mW, divide by 1000 for watts).
2. If the USB-C port is more likely to support Quick Charge or Pump Express (18W) than if the Micro-USB (obsolete models like the Redmi 8A) is 10W at most.

Example: If the AIDA64 shows 15,000 MW (15W) when connecting charging to 18W, then your Redmi limits power to 15W – take the 18W adapter with a margin.

Can I use a higher power charger?

Yes, but with reservations: Modern Xiaomi Redmi smartphones have a built-in power controller that limits the current consumed.

• If you plug the Redmi 9A (10W) into a 67W charge, the phone will only take 10W.
• If you connect the Redmi Note 12 Pro+ (120W) to 18W charging, charging will go at a reduced speed (about 10-15W).

But there are nuances:

• ⚡ Adapter quality – cheap charging on 67W They may not meet the stated characteristics and damage the phone.
• 🔋 Temperature – Even if the phone limits power, a bad power supply can warm and shorten battery life.
• 📱 Protocol compatibility – some Redmis require proprietary protocols (e.g. Mi Turbo Charge) that are not supported by universal charging.

⚠️ Note: Chargers from laptops (for example, 65W or 100W) Technically compatible with Redmi USB-C, But they can cause overheating because they don't optimize for mobile devices.

💡

If you travel frequently, take the Xiaomi Mi Compact 33W compact charging – it supports most Redmis and takes up little space.

• ⚡ Voltage surges – can disable the power controller (repair will cost 3000-5000) ₽).
• 📉 Battery capacity declines – unstable current accelerates degradation of lithium-ion cells. Poor charging reduces battery life by 20 to 40 percent, according to Battery University%.
• 🐢 False economy: No-name adapter for 300 ₽ It could burn in a month, and with it, the port. USB-C phone.

How to distinguish high-quality charging from dangerous:
