Cuktech 15 Ultra is a brand-new 20000mAh energy financial institution with massive attainable

Cuktech is a model you will not be accustomed to; it began out as a white-label producer, and merged with ZMI — a model in Xiaomi’s huge ecosystem — again in 2022. It is now aiming to achieve a world presence at the again of attention-grabbing launches; the Cuktech 30 is an enormous 40000mAh energy financial institution with a 300W energy funds and Qi integration, and the type I’m having a look at is the Cuktech 15 Ultra, a 20000mAh unit with a 165W energy funds.

The Cuktech 15 Ultra is available on Amazon for $87 as of writing, and that is the reason at the upper finish of the size, specifically while you believe that UGREEN’s Nexode 20000mAh Power Bank is selling at $59. That mentioned, the construct high quality of this energy financial institution is without doubt one of the highest of any I used, and it holds as much as the Anker Prime 27650mAh Power Bank — no small feat.

Before we get began, a observe at the naming; Cuktech says it selected its title as a result of the Čuk DC-DC converter structure, named after Slobodan Čuk. With that out of the way in which, let’s communicate concerning the design. Similar to Anker and UGREEN, Cuktech went with a vertical profile for the ability financial institution, and it is the absolute proper transfer — it makes the 15 Ultra that a lot more transportable.

There are different niceties; the gray colour scheme with the black entrance seems to be blank, and the again has a textured end that makes it simple to carry the ability financial institution. I would not have any problems with the design of the 15 Ultra, and Cuktech did a just right task on this regard.

There’s a button up entrance that turns on the panel, and also you get to peer battery lifestyles, time to price gadgets, and real-time charging metrics at the identical web page. Ideally, Cuktech will have to have driven the real-time charging main points to a secondary web page because it makes the panel glance a little bit cluttered, however that is a minor quibble. You get all of the data you wish to have, and that is the reason what in the end issues.

As it comprises a 72Wh battery, there aren’t any problems taking the 15 Ultra onboard a flight. The 20000mAh dimension is good enough to price your telephone a couple of occasions over together with a couple of equipment, and charging potency is consistent with different manufacturers I examined lately.

Obviously, you’ll’t price a telephone with a 5000mAh battery 4 occasions with the 15 Ultra; the inherent power loss whilst the usage of the ability financial institution method it has an potency of just below 60%, so you’ll be able to quite get 12000mAh of charging attainable. This is the case with all energy banks, so you are no longer lacking out with the 15 Ultra relating to charging your tech.

On that observe, the ability financial institution has 3 ports in overall — two USB-C and a USB-A connector. The primary USB-C port is going as much as 140W over the USB PD 3.1 usual, and the secondary USB-C hits 65W. The USB-A port is restricted to 18W, so it may well most effective be used with equipment. With each USB-C ports in use, you get a 165W energy funds. I’m sharing a rundown of the ability profiles, and the way the 15 Ultra handles simultaneous charging:

• USB-C1 in/out (140W max): 5V/3A (15W), 9V/3A (27W), 12V/3A (36W), 15V/3A (45W), 20V/5A (100W), 28V/5A (140W)
• USB-C2 out (65W max): 5V/3A (15W), 9V/3A (27W), 12V/3A (36W), 15V/3A (45W), 20V/3.25A (65W)
• USB-A out (18W max): 5V/3A (15W), 9V/2A (18W)
• USB-C1 + USB-C2 out (165W max): 100W + 65W
• USB-C1 + USB-A (118W max): 100W + 18W
• USB-C2 + USB-A (83W max): 65W + 18W
• USB-C1 + USB-C2 + USB-A (163W max): 100W + 45W + 18W

I used the 15 Ultra with my Vivo X200 Pro, Find X8 Ultra, iPhone 16 Pro Max, and Pixel 9 Pro XL, and it did a competent task charging those gadgets. There’s no overheating both, and Cuktech did a just right task with thermal control basically.
