Xiaomi's $20 power bank has a built-in cable and 20,000mAh — and it undercuts Anker by half
Xiaomi has launched a 20,000mAh power bank with a built-in USB-C cable for around $20 — roughly half the price of the Anker Nano 10K. The bank is already live on Xiaomi UK official and rolling out across Europe, though a formal US launch has not been announced. For anyone tired of hunting for a spare cable at the bottom of a bag, the integrated "tail" is the main draw.
The cable is the point
The built-in USB-C cable removes the most common power-bank frustration. Beyond that, the device adds two more ports — a second USB-C and a USB-A — so you can charge up to three devices at once. The catch: all three ports share a maximum of 22.5W total output, not per port. That's fine for phones and earbuds, but it won't fast-charge a laptop. The body is scratch-resistant polycarbonate in light or dark grey, weighs 343g, and keeps a rounded, minimal shape that sits flat in a bag.
Two cells, one airline-safe pack
Inside are two 10,000mAh cells wired together, giving a combined energy of 74Wh. That sits comfortably under the 100Wh IATA carry-on limit, so the bank flies as cabin luggage without any special approval. Xiaomi says it can charge an iPhone 16 Pro to 56% in 30 minutes at 22.5W, per NotebookCheck EU rollout. One thing to note on capacity: the 20,000mAh figure is the nominal cell rating; the real-world rated output is closer to 12,000mAh at standard 5V — an industry-standard gap, but worth knowing before you compare it to rivals on spec sheets alone.
Price and availability
In China the bank launched at 149 CNY (around $20). In the UK it's live on the Xiaomi Store now. In Germany it's priced at €20. There is no confirmed US retail listing — third-party imports may appear on Amazon, but Xiaomi has no official US storefront for this model. The main competition at this price sits around the Iniu 10K 45W (~$25–30), while the Anker Nano 10K starts at roughly $30–38 with higher per-port wattage. Xiaomi also offers a pricier 33W variant of the same form factor for those who want faster output on a single cable connection.
