Belkin BPB021 10,000mAh 20W USB-C Power Bank with Built-In Cable
Product description
If you want a backup charger without carrying a separate cable, the Belkin BPB021 has an integrated USB-C cable ready to use. If you also need to keep a second device powered, its additional USB-C port lets you connect both at once.
With 10,000mAh capacity, 20W output, and pass-through charging, it brings practical charging options to travel days and everyday use.

Key points
The built-in USB-C cable keeps charging simple: connect a compatible device directly, without packing a separate USB-C cable for that connection. A second USB-C port adds flexibility when you need to charge another device at the same time. When both connections are in use, the total output is shared at 15W.



The 10,000mAh capacity provides portable backup power for compatible phones, tablets, and other listed devices. An LED indicator shows the power bank’s status, making it easier to tell when it needs recharging. Pass-through charging also lets you recharge the power bank while it charges a connected device.
The housing, excluding the cable, is made with at least 72% post-consumer recycled plastic. Buyer feedback often highlights its portable size and the convenience of the attached cable, while opinions on charging speed, battery life, and cable length are mixed.

How it fits
This power bank is listed as compatible with a range of Apple devices, including iPhone 15, iPhone 16, and iPhone 17 models, as well as select iPads, Apple Watch models, and AirPods Pro 3. Listed Android compatibility includes Samsung Galaxy S22 through S25 models, and Nintendo Switch 2 is also included in the compatibility information.



For iPhone 13 and iPhone 14 devices, use a USB-C cable with a Lightning connector through the USB-C port. That connection cable is sold separately. The integrated cable is useful for compatible USB-C devices, while the second port gives you another way to connect a device or recharge the power bank.
Usage tips

Connect a single device to the built-in cable or USB-C port for charging at up to 20W. When charging two devices together, keep in mind that the power is shared, with 15W total output. For simultaneous charging of the power bank and a connected device, use its pass-through capability.
To recharge the power bank, use the integrated cable or USB-C port, the listed USB-C PD input is up to 20W. The LED indicator provides a quick status check when you’re getting ready to head out. For a day of travel, keeping the power bank in your bag with the built-in cable accessible can make topping up a compatible phone straightforward.



Questions before you buy
Can it charge two devices at the same time? Yes. Use the integrated USB-C cable and the separate USB-C port together. Their combined output is 15W, shared between the connected devices.
Can I charge the power bank while it powers a device? Yes. It supports pass-through charging, so it can recharge while charging a connected device at the same time.
What do I need to charge an iPhone 13 or iPhone 14? Use a USB-C cable with a Lightning connector plugged into the power bank’s USB-C port. That cable is sold separately.
Is it worth it?
The Belkin BPB021 suits people who want portable backup power with fewer loose cables to pack and a second connection for another device. Its 10,000mAh capacity, built-in USB-C cable, additional port, and pass-through charging make it a practical match for travel and everyday charging, especially when keeping a phone and another compatible device powered is part of the plan.
