Amazon’s promotion works in two steps: Prime members automatically see it drop to $80, then hitting the “Redeem” button applies an extra 10% off, bringing it to its lowest-ever price. If you’ve been eyeing this power bank, now’s the perfect moment to grab it.

Why the CUKTECH 15 Ultra is worth your money

The CUKTECH 15 Ultra strikes the balance between power and portability. Measuring 5.98 x 2.25 x 1.75 inches and weighing just 1.3 pounds, it’s smaller than most power banks. Its compact size slips easily into bags, making it a super convenient option for charging on the move.

The power bank has a native capacity of 20,000mAh, which meets airline safety standards for carry-on power banks. However, when charging at 5V/3A, its effective capacity measures as 15,000mAh due to voltage conversion.

That said, the CUKTECH 15 Ultra goes beyond your average power bank with its impressive speed and power. One USB-C port alone can push up to 140W, while using both USB-C ports together delivers a combined 165W — split as 100W and 65W. If you plug in all three ports, including the USB-A, the total stays at 165W, divided as 100W, 45W, and 15W.

Even its slowest port — the 18W USB-A — delivers plenty of speed for accessories or topping up a phone. Where the CUKTECH 15 Ultra truly stands out is its extensive protocol support. It’s compatible with PPS, QC, PD3.1, FCP, SCP, and MiPPS, ensuring high-speed charging across a wide range of devices.

Furthermore, the CUKTECH 15 Ultra lets you customize the first USB-C port to work as input/output, output-only, or input-only. This gives you full control over how it’s used, whether charging your devices or recharging the power bank.
