Intro: Why this power bank matters

Xiaomi 67W Power Bank 20000 is designed for users who need laptop‑grade fast charging, reliable all‑day backup, and a travel‑ready form factor in one device. With a 20,000 mAh class battery, 67 W output, and an integrated USB‑C cable plus dual ports, it targets power users, commuters, creators, and frequent travellers who juggle multiple gadgets. This guide explains whether it fits your needs, what to expect in real‑world use, and how it compares to typical 20,000 mAh banks.​

What is the Xiaomi 67W Power Bank 20000?

Xiaomi 67W Power Bank 20000 (Integrated Cable) is a high‑capacity portable charger that delivers up to 67 W output, enough to fast‑charge smartphones, tablets, and many thin‑and‑light laptops. It combines a roughly 20,000 mAh pack (three 6,700 mAh cells with rated 12,000 mAh at 5 V/3 A) with 74.37 Wh energy, keeping it under aviation limits for in‑flight use.​

The power bank belongs to Xiaomi’s latest 67 W series and has been rolled out globally, including Europe, where it is marketed with a built‑in USB‑C cable and dual additional ports. In Europe, it is listed around 45–50 EUR in markets like Germany, positioning it as a mid‑range high‑performance option rather than a budget unit.​

Key features and specifications

Core specs at a glance

• Capacity: Nominal ~20,000 mAh, rated 12,000 mAh at 5 V/3 A, 74.37 Wh energy.​
• Output: Up to 67 W max via USB‑C / built‑in USB‑C, with multi‑protocol support (PD 3.0, PPS, QC, etc.).​
• Input: Up to 65 W max over USB‑C, enabling a full self‑charge in about 2.5 hours with a suitable adapter.​

The Xiaomi 67W Power Bank 20000 supports multiple power profiles such as 5 V/3 A, 9 V/3 A, 12 V/3 A, 15 V/3 A, and 20 V/3.25–3.35 A, as well as PPS ranges like 5–11 V/6.1 A and 5–20 V/3.35 A. It is compatible with standard fast‑charging protocols including USB‑PD, PPS, QC 3.x, QC 5, DCP, and Apple 2.4 A, making it suitable for a wide range of phones and laptops.​

Ports and integrated cable

• 1 × built‑in USB‑C cable (also acts as a lanyard).
• 1 × external USB‑C port.
• 1 × USB‑A port.​

You can power up to three devices at once using the built‑in cable, USB‑C, and USB‑A, although the combined output in multi‑device scenarios is capped around 15 W total. This makes it excellent for single‑device fast charging or light multi‑device top‑ups rather than three heavy loads simultaneously.​

Design, build, and portability

The power bank measures roughly 140 × 72 × 31.2 mm and weighs around 415 g, which is typical for a dense 20,000 mAh class pack but heavier than slim 10,000 mAh models. Its blocky but compact footprint makes it easy to slip into a backpack or laptop bag, though it is noticeable in a trouser pocket.​

Xiaomi offers the 67W Power Bank 20000 in at least two colours such as beige and blue in European listings, giving a slightly more lifestyle‑oriented look than plain black bricks. The integrated USB‑C cable is flexible and doubles as a lanyard, which reduces cable clutter and adds convenience for quick grabs from a bag or desk. A small digital display shows remaining battery percentage, so you do not have to guess the charge level from vague LEDs.​

Charging performance and real‑world use

Fast charging smartphones and laptops

When paired with compatible Xiaomi phones, the power bank can deliver up to 67 W, with Xiaomi advertising that a Xiaomi 15 can reach around 67% charge in 30 minutes. In real use, that translates to flagship‑grade charging speeds on many USB‑PD capable phones and quick top‑ups during short breaks.​

For laptops, the USB‑C port and integrated cable provide up to 20 V/3.25–3.35 A, meaning many ultrabooks and Chromebooks within the 45–65 W range can be charged or at least sustained. This makes the Xiaomi 67W Power Bank 20000 a useful backup for students, travellers, and office users who work away from power outlets for hours.​

Multi‑device and self‑charging behaviour

The three‑output design lets you charge, for example, a phone on the cable, earbuds on USB‑A, and a smartwatch or secondary phone on USB‑C simultaneously. However, when all ports are used at once, the total output is significantly reduced to around 15 W shared, so individual devices will charge more slowly.​

For recharging the bank itself, both the USB‑C port and built‑in cable support up to 65 W input, so with a 65 W or higher USB‑C adapter, you can fully recharge the 20,000 mAh pack in about 2.5 hours. This is notably faster than many older 20,000 mAh banks that can take 4–6 hours at 18–30 W input, which is a major advantage for frequent travellers.​

Safety, compatibility, and travel readiness

Xiaomi uses premium lithium‑ion cells and implements nine layers of safety, including temperature protection, short‑circuit protection, over‑voltage, over‑current, and over‑charge/over‑discharge safeguards. Dual NTC temperature sensors actively monitor heat to keep high‑power charging within safe limits, which is important when running close to 67 W.​

The rated energy of about 74.37 Wh keeps the bank under the usual 100 Wh limit enforced by most airlines for carry‑on power banks, so it is typically allowed on flights. As with any power bank, it must travel in cabin luggage and may be subject to airline‑specific checks, but the capacity is well within normal guidelines.​

Because it supports USB‑PD, PPS, QC, and Apple protocols, it works smoothly with Android phones, iPhones via USB‑C or USB‑C‑to‑Lightning cables, tablets, handheld consoles, and many laptops. This broad compatibility reduces the need for multiple brand‑specific chargers and suits mixed‑ecosystem users who own devices from different manufacturers.​

Who should buy this power bank

Xiaomi 67W Power Bank 20000 is best suited for power users who carry multiple USB‑C devices and need fast, reliable top‑ups rather than occasional emergency charging. Creators, students, business travellers, and remote workers with USB‑C laptops, tablets, and phones will benefit most from the 67 W output and 65 W input.​

If you mainly charge a single phone once a day and rarely travel, a cheaper 10,000 mAh or 20,000 mAh 18–30 W bank may be a better value. But if you want laptop‑grade performance, integrated cable convenience, and global readiness, Xiaomi 67W Power Bank 20000 offers a balanced mix of features and price.​
