CUKTECH 15 Ultra Power Bank for Laptop, 20,000mAh 140W Portable Charger, Smart Display, External Battery for Outdoor Work and Travel, for iPhone 16/15, MacBook, Samsung, and More (Flight-Approved)

I use this power bank for almost daily for about a year. Charges my phones, MacBook Air and Steam Deck incredibly fast. If you charge the power bank with 2 different fast usbc power supplies it goes into beast mode and the power bank will go from 0 to 100% in 30 minutes

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.

It is very powerful and good product

Very soundly built and sturdy. It holds a charge very well without needing a recharge.

super fast charge and discharge, quality is better than the ugreen and is on pair with anker.

Powerbanks is one product industry that is a total PITA. It truly is the wild west, prices can vary wildly as can their performance. There is a reason there are dozens of YT channels and hundreds of review websites for a product that should be relatively simple and plug and play. I did a ton of research and alot of powerbanks especially the cheaper ones just outright fib about the capacity or the charging ability. A Company claims its 20000mah capacity but in reality it can be half that. Another big issue is charging performance. Heat is a big bottleneck. A Company might claim it charges at 140W and while it technically might , only for 10 minutes before it gets too hot and throttles down to 65w Im very happy to report The cuktech 15 ultra performs perfectly, and hits all advertised metrics. Its a true 20k capacity and had very little to no throttle down. Its build quality is fantastic. It looks great and has some really handy features like being able to dedicate a USB to either output or input only. Devices can also be powerbank picky. I could write an essay on the why's explaining it but im just going to say the cuktech 15 prime handles a wide variety of PD certifications. I have a Lenovo tablet that is picky about what "fast charging" it accepts (just because a charger outputs 45w doesn't guarantee device will accept 45w) the Cuktech has perfect compatibility with all my devices (Samsung S23 and 24 ultras/lenovo yoga tab/idea tab plus/lenovo legion go 2) In short its a great powerbank, one of the best i have had, and ive owned models from every major brand. So why the 4 star? SIZE The Cuktech is a very common size. Once you get into 20k+ mah you get a "soda can" size powerbank. All of them are this size (except for a simgle new INIU model) they may vary slightly slightly but almost every brand is around the same size. this isnt anything automatic knock against the Cuktech, its just how the cookie crumbles with our current battery technology. However, in my opinion if im going to be forced to carry this size of powerbank around then I personally want to maximize my capacity and thats where the Anker Prime 250w 27650 mah comes into play. If the extra capacity doesn't bother you, if the anker price doesn't bother you (double the cost) then this is THE power bank to get.

Excelente producto, cumplió con mis expectativas.

One hour full charge with a laptop charging cable!

Excelente producto, cumple con todo lonque se dice. Carga ultra rápida

Power bank molto buono,dura molto e lo puoi mettere in carica con 2 caricatori insieme

I’ve been using the CUKTECH 15 Ultra for a few weeks now, and it has exceeded my expectations. The build quality feels premium and robust, fitting easily into a backpack side pocket despite its high capacity. ​Pros: ​Blazing Fast Charging: It easily handles my MacBook Pro and iPhone simultaneously without breaking a sweat. The 150W total output is no joke. ​Informative Display: The built-in screen is fantastic. It shows real-time wattage, which is very helpful for monitoring battery health and charging speeds. ​Fast Recharging: The power bank itself recharges incredibly quickly if you have a high-wattage wall charger. ​Design: The "Pillar" design makes it much easier to grip than the old, flat brick-style power banks. ​Cons: ​It is a bit heavy, but that is expected for a 20,000mAh+ high-output cell. ​Overall, if you need to keep a laptop and a phone alive during a long day of travel, this is the best bang for your buck on the market right now. Highly recommended.

Perfecta para cargar hasta 3 dispositivos y esta genial para llevarla y transportarla además de ver a cuanto carga en su pantalla muy recomendable

The price point is sweet and quality is as good as UGreen or infact event better. The grey is metallic finish and looks much better than it is in the picture. I’ve used black power banks earlier but it leaves a lot of scratches. Worth it
