Aaoyun B2 10,000mAh Power Bank, 22.5W PD, Built-In USB-C Cable

At 0.6 inches thick, the Aaoyun B2 packs 10,000mAh of portable power into a slim, matte-black design. Its compact size makes it easy to carry for a commute, a day out, or a trip when you want backup power close at hand.

With up to 22.5W PD fast charging and a built-in USB-C cable, it gives you a straightforward way to charge compatible devices without carrying a separate cable for that connection. The power bank supports bidirectional fast charging, so the same fast-charging feature applies when replenishing the pack.

The B2 is designed for phones, tablets, earbuds, and smartwatches, including compatible iPhone and Samsung Galaxy models. Its integrated cable and additional connection options make it useful when you carry more than one device.

How to use it

Connect a compatible device to the built-in USB-C cable or use the power bank’s USB-A and USB-C connections. The product is specified to charge up to three devices at once, which can help when you need to top up a phone alongside smaller electronics. Check that each device can connect to the available cable or port before charging.

For a daily routine, keep the B2 in a bag or pocket and use it when your phone needs a recharge away from a wall outlet. On a trip, the 10,000mAh capacity provides a portable reserve for compatible phones and other personal electronics. The stated device compatibility includes iPhone 17, 16, and 15 models, Samsung Galaxy phones, tablets, AirPods, and Apple Watch Series 8 and 9.

Why it makes sense

A conventional power bank may require you to pack a separate cable for every charging connection. The B2’s built-in USB-C cable reduces that extra packing for compatible devices, while its other connection options give you flexibility for additional electronics. That combination is practical for a work bag, travel kit, or everyday carry where keeping accessories together matters.

Its 22.5W PD fast charging is a useful feature when you want a faster charging option than a basic power bank, and bidirectional fast charging supports faster recharging of the power bank itself. The result is a portable charger designed to serve both as a phone backup and as a shared power source for several personal devices.

Highlights

The aluminum-alloy casing and slim profile give the B2 a compact form for carrying between home, work, and travel. It measures 4.47 x 0.6 x 2.67 inches and weighs 6.8 ounces, so it can fit easily into a packed bag without taking up much space. Its matte-black finish keeps the design understated.

The 10,000mAh battery capacity, 22.5W PD charging, built-in USB-C cable, and support for charging up to three devices are the central reasons to choose this model. Multiple protections are also specified for overvoltage, overcurrent, overpower, and short circuits. For air travel, the product is described as compliant with TSA aviation standards, carry-on rules can depend on the airline and route.

Is it worth it?

The Aaoyun B2 makes sense for people who want a compact power bank with its own USB-C cable, fast PD charging, and enough capacity to support more than one personal device. It suits you if reducing loose cables in your everyday bag matters as much as having backup power for a compatible phone. For commuting, travel, or days spent away from an outlet, its slim build and built-in cable make portable charging simpler to carry and use.
