CUKTECH 2-in-1 5000mAh 67W Portable Power Bank with Foldable AC Plug & 22W Output

The CUKTECH BA651 is a 2-in-1 portable power bank and foldable AC plug charger for keeping compatible smartphones and tablets powered at home, at work, or while travelling. Its 5000mAh lithium-ion battery, 67W maximum AC charging power, and 22.5W maximum battery charging power bring wall charging and backup power together in one compact device.

Key Takeaways

• Two useful roles: portable battery and foldable AC plug charger in one unit.
• Battery specification: 5000mAh, 3.6V, 18Wh lithium-ion battery.
• Wall charging power: up to 67W maximum AC charging power.
• Device charging power: up to 22.5W maximum from battery power.
• Connection options: USB-A and USB-Type C output ports.

What Is the CUKTECH BA651?

The CUKTECH BA651 is a compact charging accessory that combines a portable battery with a built-in foldable AC plug charger. Rather than carrying a separate wall adapter and small backup battery, shoppers can use one device for both charging situations.

The product is associated with CUKTECH and XIAOMI, and its model identifier is BA651. At Adatun, we focus on the practical details that help shoppers compare charging gear: capacity, wattage, ports, and the type of use the design supports.

A Single Device for Desk, Bag, and Socket

The 2-in-1 design pairs a portable power bank with a foldable AC plug charger. The foldable plug is built into the unit, while built-in cables are part of the portable design, helping reduce the number of separate accessories to manage.

This format suits people who move between a wall socket and a bag during the day. It is not a large-capacity battery intended for extended multi-device use; its stated 5000mAh capacity instead makes it a compact option for short backup-power needs.

Key Features

• 5000mAh lithium-ion battery: The battery is specified at 5000mAh, 3.6V, 18Wh. Those figures describe the installed battery, giving shoppers a clear basis for comparing compact power products.
• 2800mAh rated capacity: The stated rated capacity is 2800mAh (5V/2.4A). Rated capacity is a separate specification from cell capacity, so it is useful to consider when planning a practical on-the-go top-up.
• 67W maximum AC charging power: When used as an AC charger, BA651 supports up to 67W maximum. Actual charging performance depends on the connected device, cable, and charging protocol.
• 22.5W maximum power-bank charging: In battery mode, the unit provides up to 22.5W maximum charging power. This gives compatible devices a higher-wattage option than basic low-power charging accessories.
• USB-A and USB-Type C ports: The available USB-A output port and USB-Type C output port support connection with compatible smartphones, tablets, and other USB-charged devices.
• Plastic shell and advanced circuitry: The plastic shell houses the battery and circuitry. The listed advanced circuitry is designed to support stable charging operation.

Specifications

The wide 110–240V, 50/60Hz, 1.8A AC input specification describes the supported input range for the built-in charger. Before use, shoppers should check the local outlet format and ensure that the plug arrangement is appropriate for their destination.

The listed figures should be read as maximum specifications rather than a promise of identical results with every device. A phone, tablet, cable, and battery state can each affect the charging power a connected device accepts.

Why Everyday Travellers Choose This Format

A conventional travel kit may include a wall charger, a cable, and a battery pack. The BA651 addresses the charger-and-battery portion of that kit with its foldable AC plug and integrated battery. That can be useful for commuters, students, and travellers who value a less fragmented carry setup.

The 67W AC mode matters most when a suitable device and cable can use that level of charging power. The 22.5W battery mode is a distinct specification for charging from stored battery energy, so buyers should choose based on the role they expect to use most often.

Use Case: A Workday Backup

For a workday, the 5000mAh battery can serve as a compact reserve for a compatible smartphone or tablet when a socket is not nearby. USB-A and USB-Type C connections offer flexibility for devices that use either port type.

The rated capacity of 2800mAh (5V/2.4A) is particularly useful context for realistic planning. Buyers who need repeated charging across several devices may prefer a higher-capacity power bank, while buyers seeking a smaller backup may find this balance more relevant.

Use Case: Travel and Overnight Stops

For travel, the foldable AC plug allows the BA651 to function as a charger when mains power is available, then as a portable battery away from a socket. The stated 110–240V input range covers a broad electrical range, but it does not replace the need to check physical plug compatibility.

Its compact approach is best for keeping essential USB-powered devices ready rather than replacing every charger in a larger electronics bag. Shoppers carrying laptops or several power-hungry devices should compare their devices’ requirements with the available ports, cable capability, and the product’s stated wattage.

Choosing the Right Charging Setup

Choose the CUKTECH BA651 when a combined AC charger and small backup battery better fits your routine than two separate items. Its USB-A and USB-Type C ports make it relevant for compatible modern devices, while the built-in cables further support a simplified carry arrangement.

Consider a larger battery capacity if long periods away from power are your priority. Consider a multi-port desktop charger if several devices need to charge at once from a fixed location. BA651 is designed around portability and dual-function convenience, not maximum stored energy.

Helpful Compatibility Checks

• Confirm that your smartphone, tablet, or other device charges through USB-A or USB-Type C.
• Check the charging requirement of each device before expecting the 67W maximum AC figure.
• Use a cable suitable for the charging level your connected device supports.
• Check physical outlet compatibility when travelling, even where the voltage range is supported.

These checks help set appropriate expectations and make product comparisons clearer. They also distinguish battery capacity, rated capacity, wall-charger wattage, and battery-mode wattage—four specifications that are related but not interchangeable.

What’s Included

• CUKTECH BA651 2-in-1 portable power bank and foldable AC plug charger

The supplied product information identifies the BA651 unit as the included item. No additional accessories are listed in the available specifications, so shoppers who need a particular cable or travel plug adapter should confirm those requirements separately before purchase.
