The Xiaomi 33W Power Bank 20000mAh (Integrated Cable) carries its own USB-C cable, so the most common charging job, a phone on the go, needs nothing else in your bag. Next to that cable it has a USB-C port and a USB-A port, it can charge three devices at once, and it tops out at 33W. Xiaomi is clear that the 20000mAh figure is cell capacity: the rated capacity at 5V/3A is 12000mAh. This is the blue version, model PB2030MI.

Xiaomi 33W Power Bank: The Built-In Cable
The cable on the Xiaomi 33W Power Bank is a USB-C lead that loops out of the top of the case and plugs back in, so it doubles as a carry loop. Xiaomi describes it as a USB-C power port with an integrated cable: it charges your phone, and it can also recharge the power bank itself from a wall adapter.
For anyone who keeps forgetting cables, this is the main reason to choose this model. Xiaomi does not publish the cable length.
Ports, Outputs and Charging Three Devices
Besides the integrated cable there is a USB-C port and a USB-A port. Xiaomi’s specification sheet lists two outputs rated up to 33W (5V/3A, 9V/3A, 11V/3A, 12V/2.5A, 15V/2A, 20V/1.5A) and a third rated up to 22.5W (5V/3A, 9V/2.23A, 10V/2.25A, 12V/1.67A), with 33W as the total maximum.
The Xiaomi 33W Power Bank can charge three devices simultaneously, but Xiaomi notes that if their combined demand exceeds the total output, all three may not charge at once. Two inputs accept 5V/3A, 9V/2.5A or 12V/2.5A.
Xiaomi’s own 30-minute tests show about 71% on a Xiaomi 13 Pro, about 68% on a Xiaomi 13T Pro and about 55% on an iPhone 15 Pro.
20000mAh vs 12000mAh: What You Actually Get
The cells hold 20000mAh at their own voltage, but converting that energy to the 5V a phone receives costs some of it, so Xiaomi rates the usable output at 12000mAh (5V/3A). The rated battery energy is 74Wh (typical 75.48Wh).
74Wh is below the 100Wh level that most airlines accept in cabin baggage without approval, but rules differ by airline, so check before you fly. Power banks never go in checked luggage.
Low-Current Mode and Safety
Small devices such as earbuds and fitness bands draw so little current that some power banks switch off. On the Xiaomi 33W Power Bank, a double press of the battery-check button turns on low-current charging for these.
Xiaomi lists nine layers of protection: temperature, short-circuit, reset, input overvoltage and overcurrent, output overvoltage and overcurrent, and over-charge and over-discharge protection.
Who This Is Not For
At 33W total, the Xiaomi 33W Power Bank is a phone and tablet charger, not a laptop power bank; for laptops look at higher-wattage models such as our Xiaomi 50W Power Bank 20000mAh. At 127 × 70.5 × 30.5 mm it is pocketable in a jacket but thick in jeans, and Xiaomi does not publish its weight. There is no wireless charging and no display showing an exact percentage.
