This is the company's third contract-manufacturing unit in the country and is located in Noida.
It has a capacity to make seven power banks a minute, Xiaomi India Head Manu Jain told reporters here.
The 10,000 mAh Mi Power Bank 2i and 20,000 mAh Mi Power Bank 2i will be made at the facility, he added.
Jain did not disclose the investment details.
Spread over 2.3 lakh sq ft, the facility will initially employ over 500 people and the number will be ramped up gradually.

These have provided employment to over 5,000 people with 90 per cent being women, Jain said.
"Today, more than 95 per cent of our smartphones sold in India are assembled locally... We are open to expanding capacity as well as setting up new factories if there is a requirement," he added.
Talking about the power bank market in India, Jain said there is no third-party data available for the market.
"However, the potential is huge. A major challenge is fake power banks flooding the market. We are trying to address this by adding hologram security markers to help customers know they have bought a genuine product," he said.
The hologram sticker has a scratch card that reveals a set of numbers that can be checked online to know if the product is genuine.
