10000mAh magnetic power bank

A 10000mAh lithium-ion power bank with 20W PD fast charging and a built-in dual-head cable that combines USB-C and Lightning connectors. Strong magnetic attachment works with iPhone 12 through 17 series or magnetic cases using the included adhesive metal ring. It delivers wired power only, with no wireless charging function, and an LED display shows remaining capacity.

Capacity and charging headroom

The 10000mAh cell charges iPhone 17 about 1.8 times, Galaxy S25 about 1.5 times and most Android phones roughly 1.4 to 1.6 times via the built-in cable. Output is rated at 20W over USB-C Power Delivery, which is nearly three times faster than 7.5W wireless alternatives. The pack runs at 5 volts and uses lithium-ion chemistry; it will not charge laptops or other high-draw devices.

Fit in your everyday carry

Dimensions are 4.1 by 2.6 by 0.6 inches and weight is 0.38 lb (174 grams), so it snaps onto the back of a phone without blocking cameras or adding bulk. The integrated cable doubles as a carry strap, removing the need for separate cords. An adhesive metal ring is supplied for non-magnetic cases, and full safety protection covers over-current, over-voltage and short-circuit risks.

Questions about this item

Will the built-in USB-C and Lightning cable reach my phone while it's magnetically attached to the power bank?

Yes, the integrated dual-head cable is designed to connect directly while the power bank snaps onto your iPhone 12, 13, 14, 15, 16 or 17 series, or a magnetic case, so you can charge and use the phone at the same time.

How do I confirm the 20W PD fast charging is active after I plug in?

The LED display shows the real-time power output; when it reads 20W you know the PD fast-charging handshake has succeeded.

Does the box include the adhesive metal ring for non-magnetic phones or cases?

Yes, the package contains the 10000mAh power bank with its built-in dual-connector cable and an adhesive metal ring so you can add magnetic attachment to any phone or case.
