CUKTECH 25 Power Bank SE: Compact 25,000mAh Charger

CUKTECH has launched the 25 Power Bank SE, a 25,000mAh portable charger built to power laptops, phones, tablets, and accessories from a single battery pack. It supports up to 100W output, can recharge at up to 100W, and includes a built-in USB-C cable for travelers who would rather leave one more wire at home.

The CUKTECH 25 Power Bank SE is available now through Amazon US for $62.99 as part of a limited-time deal. Its regular price is $69.99.

Enough Power for Phones and Laptops

The 25,000mAh battery is rated at 90Wh, placing it below the FAA’s 100Wh limit for batteries carried onto commercial flights. That makes the Power Bank SE particularly relevant for travelers, remote workers, and commuters carrying several devices.

CUKTECH says the battery can provide up to 3.2 full charges for an iPhone 17 Pro Max or roughly 1.2 charges for a MacBook Air.

The power bank can deliver up to 100W to compatible devices, giving it enough output to handle many USB-C laptops along with smartphones and tablets. According to CUKTECH, a 13-inch MacBook Air with an M3 chip can reach 56% charge in around 30 minutes.

Those figures come from CUKTECH’s own testing, so real-world results will vary by device, battery condition, charging protocol, and usage.

Three Devices Can Charge at Once

CUKTECH built three charging connections into the 25 Power Bank SE: an integrated USB-C cable, a separate USB-C port, and a USB-A port.

That setup allows users to charge three devices simultaneously, such as a laptop, phone, and pair of wireless earbuds. The permanently attached USB-C cable is a practical touch for travel, particularly for anyone with a talent for packing a charger and somehow forgetting the cable.

A built-in digital display shows the remaining battery level and current charging output, making it easier to see how much power is left without relying on an app.

100W Recharging Cuts Down Wall Time

The power bank itself supports up to 100W input when paired with a compatible USB-C PD charger. CUKTECH says 15 minutes of charging can restore roughly 25% of the battery.

The company estimates that amount could provide up to 33 additional hours of iPhone 17 runtime. Lower-powered wall adapters will still recharge the battery, but at reduced speeds.

CUKTECH includes real-time temperature monitoring and a multi-point protection system intended to guard against overheating. The company says the charger supports multiple fast-charging protocols for use with a broad range of hardware.

Compatibility includes Samsung Galaxy and Google Pixel phones, MacBook Pro and MacBook Air laptops, iPhone 15 through iPhone 17 models, tablets, and other USB-powered accessories.
