An absolute beast
An amazing power bank with incredibly fast input, extremely powerful output, great features, good net capacity, and high compatibility. This is the best 20k mAh power bank its price range.Can charge the power bank at 165W via two input ports (100W + 65W); so-called “Beast Mode” charging. Beginning with the battery fully depleted (0% battery), at 165W input: battery reaches 50% after 10 minutes, 68% after 20 minutes, 80% after 30 minutes, 100% after 40 minutes. Fast! Even charging at “only” 100W input, it will fully charge in under an hour.Conversely, beginning with the power bank fully charged (100% battery), can sustain 140W output from a single port until fully depleted without throttling.Or, can sustain 165W output (100W + 65W) without throttling until 15% remaining battery, at which point it throttles down to 100W. Impressive!I own many power banks, and this is easily one of the best – all the more so considering the price point.

5/5 – Excellent Power Bank
The CUKTECH 15 Ultra stands out with two features:1. Manual USB-C1 mode selection (IN-only, OUT-only, or auto IN/OUT) — eliminates PD negotiation guesswork when charging another bank or device. Super practical for daisy-chaining.2. True 165W dual-port input — recharges very fast (often under an hour) while respecting modern thermal limits.140W output, clear display, solid 20,000mAh capacity, and reliable build. Highly recommended for power users!

After used, i had some thoughts
Great battery capacity, charge pretty fast as to its capacity, however I took off a star due to its heavy weight and display that I find it not that pleasant to read, but it could be a more subjective viewpoint. The quality is without a doubt.

Best power bank
The quality of the power bank is good. Its strongest point is beast mode, which helps charge very quickly. The three out gates are truly unbelievable. It’s very easy to use. It would be perfect if it were a little lighter.

Only seen 150watts with the right chargers

Found out by accident.
the cable you use makes a difference. The display tells you the capacity of the cable when you start to charge. The supplied cable is 6A but the ones I already had were only 3A.
