High-Power Charging Without the Cable Clutter

Keep your laptop, tablet, phone, and everyday technology powered wherever work takes you.

This 165W laptop power bank combines a 20,000mAh battery, built-in retractable USB-C cable, aluminum-alloy body, and full-color TFT display in one compact portable charger. It delivers up to 165W combined output, including up to 100W from a single compatible connection, making it suitable for power-hungry USB-C laptops and smaller mobile devices.

Pull out the integrated cable, connect your device, and start charging without searching through your bag for a separate cord.

Why You’ll Love It

Built-In Retractable USB-C Cable

The integrated cable extends when needed and retracts neatly into the power bank after use. It reduces loose-cable clutter and makes quick charging more convenient during commutes, meetings, classes, and travel.

Up to 165W Combined Fast Charging

Charge multiple compatible devices with up to 165W total output.

The supplier lists support for charging two compatible devices at up to 100W and 65W simultaneously. Actual output depends on the selected connections, battery level, device requirements, cable capability, and charging conditions.

Up to 100W Through One Connection

A compatible USB-C laptop can receive up to 100W from a supported single output, making the power bank suitable for many USB-C Power Delivery laptops.

The connected device controls the actual wattage it accepts.

20,000mAh Portable Capacity

The 20,000mAh battery provides additional power for laptops, tablets, smartphones, headphones, watches, and other compatible USB-powered devices when a wall outlet is unavailable.

The number of charges varies according to device battery size, voltage conversion, charging efficiency, usage, and environmental conditions.

Full-Color TFT Information Display

• Input power
• Output power
• Battery information
• Adjustable display brightness

Low-Power Charging Mode

Activate Small Power Mode for lower-current accessories such as:

Aluminum-Alloy Unibody Design

The metal exterior provides a premium finish while helping transfer heat away from the internal charging components.

Avoid describing the casing as “military-grade” or “aerospace-grade” unless your supplier provides recognized testing or material certification.

Multiple Charging Protections

The supplier lists 13 charging protections intended to support safer charging. Confirm the exact protection mechanisms before naming them individually in your product page or marketing graphics.

Product specifications

Charging speed and capacity performance depend on the device, supported charging protocol, cable, selected output, battery temperature, and current power-bank charge level.

Device compatibility

The power bank is designed for compatible USB-C Power Delivery devices, including:

• USB-C laptops
• Tablets
• Smartphones
• Handheld gaming devices
• Wireless headphones
• Smartwatches
• Small USB-powered accessories

Laptop compatibility

For laptop charging, confirm that the laptop:

1. Supports charging through USB-C Power Delivery.
2. Requires no more than the supported output.
3. Uses a suitable USB-C cable.
4. Does not require a proprietary barrel-style charger exclusively.

A physical USB-C port does not always mean the laptop supports USB-C charging.

Phone and tablet compatibility

Compatible phones and tablets will negotiate their own supported charging speed. A device that does not support 100W charging will draw only the wattage it can accept.

Air-travel information

Do not publish “TSA-approved” as an unconditional product claim. For U.S. air travel, power banks must be packed in carry-on baggage rather than checked luggage. Lithium-ion batteries rated at up to 100Wh are generally allowed, while batteries between 101Wh and 160Wh require airline approval. Confirm the watt-hour rating printed on the physical unit and advise customers to check their airline’s current policy before traveling.

Recommended customer-facing wording

Travel-ready design: Suitable for carry-on use when the unit’s printed watt-hour rating and the passenger’s airline rules permit. Power banks must not be packed in checked luggage.

3. Attach the compatible laptop, phone, tablet, or accessory.
4. Confirm the live charging wattage on the display.
5. For low-current devices, long-press the power button to activate Small Power Mode.
6. Recharge the power bank using a compatible USB-C Power Delivery charger.

Frequently asked questions

Can this power bank charge a laptop?

Yes, when the laptop supports USB-C Power Delivery and its charging requirements fall within the power bank’s supported output.

Does it output 165W from one port?

No. The supplied specifications describe 165W as combined output. The maximum listed output from one compatible connection is 100W.

Can it charge two laptops simultaneously?

The supplier lists support for up to 100W and 65W simultaneous output. Both laptops must support USB-C Power Delivery, and actual output can vary according to the connection configuration and available battery power.

Is the retractable cable included?

Yes. The USB-C cable is built into the power bank and retracts into the casing when not in use.

Does it include another charging cable?

Yes. A separate 240W-rated USB-C to USB-C cable is listed as included.

Is a wall charger included?

A wall charger is not listed in the supplied package contents. Customers may need a separate compatible USB-C Power Delivery charger.

Can it charge earbuds and smartwatches?

Yes. The dedicated low-power mode is intended for compatible low-current accessories such as earbuds and smartwatches.

Does 20,000mAh mean my device receives the full 20,000mAh?

Not exactly. Some stored energy is lost during voltage conversion and charging. Usable output varies by device, charging voltage, temperature, cable, and efficiency.

Can I put it in checked luggage?

No. Power banks must be carried in the aircraft cabin rather than placed in checked baggage under current U.S. guidance. Customers should also check their airline’s requirements.

Does the aluminum casing become warm?

Some warmth during high-power charging can be normal. Customers should keep the power bank uncovered, allow airflow around it, and stop using it if it becomes unusually hot, damaged, swollen, or emits an odor.
