Xiaomi 10000mAh WPB1026S Magnetic Power Bank Launched: 5 Key Specs

Xiaomi has launched a slimmer, stronger magnetic power bank in China. The Xiaomi 10000mAh 45W Ultra-Thin Magnetic Power Bank, model WPB1026S, costs 399 yuan (about $60) on Xiaomi Youpin and follows the WPB1025S released earlier in 2026, according to Gizmochina on October 10. It is smaller, lighter and faster than its 33W predecessor.

Here is the full picture, including what the numbers mean and what is still unknown for other markets.

Slimmer Body, Bigger Output

Xiaomi says the new unit is 35% smaller, 43 g lighter and 6.6 mm thinner than the 33W version. It measures 102 x 70.5 x 13.2 mm and weighs 195 g, with an aluminium body in silver-white or dark gray. The size gain comes from a silicon-carbon anode (16% silicon, 840Wh/L) in two 5,000mAh cells.

Charging Speeds

Wired output reaches 45W through a single USB-C port, with 30W input for refilling the bank itself. The magnetic pad delivers up to 20W to compatible Xiaomi phones, including the Xiaomi 15 and 17 series, while the iPhone 17, iPhone 17 Pro and iPhone Air get 7.5W. If you charge two devices at once, wired and wireless together, the combined output is capped at 15W, so expect slower speeds in that mode. The USB-C port also reports temperature, voltage and status data.

Safety and Travel

Xiaomi includes an NTC temperature chip and a graphene heat-dissipation layer, and says the bank meets China’s GB 47372-2026 standard. At 10,000mAh it falls under the 100Wh air-travel limit, which makes it carry-on friendly under common airline rules.

What Is Not Confirmed

This is a China launch, and the following is not confirmed:

• A global or India release, or any price outside China.
• Whether the 20W and 7.5W figures hold in everyday use, as they are manufacturer numbers.
• The exact battery-life gain from the silicon-carbon anode in real conditions.
• Compatibility with phones beyond those listed.

Always check local certification and warranty terms before importing a power bank, since rules vary by country.

Quick Answers

Verdict

The WPB1026S looks like a smart upgrade for people who want a thin, magnetic bank that still fast-charges a laptop-class phone. The price is the gate: until Xiaomi confirms other markets, this remains a China-only product.

It is also worth understanding what a silicon-carbon anode changes. Compared with the traditional graphite anode, adding silicon raises energy density, which is how Xiaomi fits 10,000mAh into a body only 13.2 mm thick. The usual concern with silicon is swelling over many charge cycles, so long-term capacity retention is something reviewers will test over months. Magnetic power banks also depend on alignment: if the phone case is thick or not magnet-compatible, wireless speeds can drop well below the quoted 20W. Buyers who mostly use the USB-C port at 45W will see the most consistent results, and the wireless pad is best treated as a convenience for short top-ups at a desk or on the move.
