CUKTECH15 Ultra Power Bank, 20000mAh 140W Laptop Charger, 3-Port USB C Charger, PD3.1 Fast Charging Battery Pack with Smart Display, Compatible with iPhone 16/15/14/13, Samsung, MacBook, Dell, etc

The media could not be loaded. This Cuktech battery pack measures 6" x 2.25" x 1.75" and weighs 20.8oz. Its 20,000 mAh capacity falls under the 100Wh limit allowed by the FAA for US flights.The battery pack has a colorful display with some techie information like power delivery and internal capacity. There are a couple menus that control the input/output behavior of the USB-C ports and whether or not the screen should be always on when charging. When the screen is off, pressing the small button turns it on.The display briefly shows that it recognizes an Apple product when it is plugged in, along with the current capacity of the cable being used. I don't know if can recognize other popular hardware brands.The internal 20,000mAh battery can be charged through both USB-C ports simultaneously! I used one 87W MacBook Pro charger to charge using one USB-C port and noticed the Cuktech was able to consume 80W to charge itself, which is already higher than what I was expecting from the charger. Using two MacBook Pro chargers puts the charger into Beast Mode with an accompanying animation.When the internal battery is low on charge, it is stated that Beast Mode can draw up to 165W from two chargers. I was able to get it pull just shy of 150W using two MacBook Pro chargers. When the battery is near full, beast mode slows down and appears to only consume power from one charger to top itself off. This Beast Mode is the most impressive thing I've seen in battery packs.When charging devices, the pack is advertised to deliver up to 140W of power. However, I wasn't able to verify that limit because I don't have devices that are so demanding. But I was able to get the charger to output 102W while charging my iPhone, MacBook Air and iPad, the first two devices from the two USB-A ports.This pack can also deliver over 30W to my iPhone even when charging other devices.I've used a handful of battery packs before but this one is by far the most impressive.

This is a perfect power bank to keep in your bag. I keep this along with a USB-C to see in USB-C to light cable, and I feel prepared to charge anything I might need to charge.For starters, the 165 W charging abilities is actually much more useful than I expected. Charges the entire power bank insanely quick luckily for me I have two 100 W USB-C's on my desk and so just plugging this into both of those gets the power bank charged less than 30 minutes.The charging ability of this is incredible as well. The fact that I can do 100 W over USB-C one is incredibly useful. I use it to charge my M1 pro Mac and it charges at the full speed of a watts. It's quite funny this power bank feels like it's lower capacity than it actually is because it charges so fast watching my Mac go from 5% to 80% as quick as it does from this is pretty crazy.The usability of this power bank is pretty good too. You don't really ever have to use any of the settings that it has when it comes to setting ports to input or output only and in my experience, I haven't, but I can see the cases where this might be useful, especially when using this for other devices that may be power master/slave. However, the screen that displays information is fantastic. As an electrical engineer, it is always fun to know how much power our device is taking in and to see that as well as the voltage and current for each channel is really neat. Love that feature a lot.This power make is an absolute beast that will be able to tackle any challenge you might throw it. Really happy with it and you will find yourself to be the same.

This power bank is great for using with my Surface Laptop 6 and Legion Go. At 20,000mAh, I'm lucky to get another couple of hours of battery for my devices. I'd have loved more capacity but this form factor is good enough for me to be satisfied. I also appreciate that this is under the max allowed amount for air travel.The digital display gives a clear reading for how quickly it is being charged or charging another device. I like seeing the power output even if I won't do anything with that information. One useful thing it does give me in addition to the input / output is an estimate charge time / remaining time it has. That is a thoughtful feature that is actually pretty useful.Both USB C ports can input and output though one port can handle more wattage. If you wanted to control how fast you recharge this battery pack, you could use the C2 port for slightly slower charging.There are other options on Amazon that offer more capacity at a lower price with similar features. I have an Iniu that I like a bit better since it has more capacity at a lower price. I think this could be a bit cheaper to compete in terms of value.What I liked about it: Nice features. Charges up fast and charges other devices fast.What I didn't like: Poor value compared to other listed products on Amazon.Overall, I recommend this if you can get it on sale for a better price than competing products.
