Smaller, and almost as powerful as the Cuktech 20.
Reviewed in the United States on December 31, 2023
This is the Cuktech 15 and it really delivers as a high-powered mobile charging solution for many of your small devices. When I connect it to all of my compatible Galaxy devices, I get “Super Fast Charging 2.0” banner messages on my lock screens or notification slider that tells me I’m getting up to 45W. This is from the smaller, more scaled-down version of Cuktech’s premium power banks. This one has a 20,000 mAh battery that provides up to 150W from 2 USB-C ports and a single USB-A. In the box is just the unit itself and a branded 6A USB-C cable that’s about 4 feet long.
In use, there is a simple LED display on the top side with a single button to the right of it. The device will automatically power on when connected to something, and the number display will flash on and off repeatedly during charging to indicate its rapid charge mode. You can double-press to switch to 15W charge mode if you prefer, but I cannot think of a reason why anyone would. This power bank talks to your device and will only send what the device will accept. I’ve had the best luck charging this unit with a 65W wall adapter. I don’t know if this one likes 100W chargers, as mine glitched once and told me it was fully charged even though it showed 72% right after I plugged my phone in. I’ve only seen this happen one time, though. Since I have 65W adapters on hand, I just use those with this one and it still charges fully in well under an hour. This doesn’t have the swag of my more expensive Cuktech 20, but this Cuktech 15 holds its own as a cheaper, slimmer high-output power bank that can still charge a laptop. 5 stars.

VERY robust construction. Excellent electronics design. Only one mild disappointment
Reviewed in the United States on December 22, 2023
It was clear from the get go that this was not a LiPoly construction, but made with Li-Ion cells – which is relatively unique construction for power banks (in my experience, anyway). In this case it was four EVE INR21700/50E cells, rated at 5Ah each.
I can’t get over the beautiful construction used here. This is the most well constructed battery pack I’ve “disassembled” to date. I had to put that in quotes – because I had to absolutely mutilate the (ABS?) plastic housing to get at the internals. And I mean peeling it away chunk by chunk (carefully) with cutters. This thing is *solid*. I’m convinced you could drive over it with a car and suffer no ill effects.
Now. That brings us to the disappointment. This battery uses four 5Ah batteries in parallel – which is indeed 20Ah. But that’s 20Ah at 3.7 volts. Given that the output voltage varies depending on use-case, and none of those use cases are at 3.7 volts – I feel like all the marketing claims involving “150 Watts” and “20,000mAh” are misleading. 20Ah at 3.7 volts is 74Wh. 74Wh at 150 Watts is roughly 30 minutes. Sounds a lot less impressive than “20,000mAh” eh?
No one lied, so it’s hard to be that upset, but it’s disappointing considering how impressive this pack is on the whole. This would be 5 stars all day long if they were a little more transparent about the “real world” capacity.
Still – this is an impressive piece of kit! So much so that I won’t let it go to waste. I love the construction so much, that I’m going to repurpose the PCB in a 3D printed case with a dewalt compatible socket and use it for camping and other portable charging needs.
(Oh, and not really worth affecting the review – but honestly, who comes up with these names? “Cuck-Tech?” Just hire someone to name your products…)
