CUKTECH NO.20 140W Power Bank, 25,000mAh 3-Port Laptop Portable Charger, Fast Charging Battery Pack for Travel and Outdoor Work, Compatible with iPhone 16/15/14 Series, MacBook, Samsung, and More

So far, a solid, well-built power bank with UPS abilities for single board computers like Raspberry Pi. I was looking for another solution that was similar to the ZMI QB826G which doesn’t renegotiate all ports when a new USBC cable is plugged in. This guy does it! So it’s better than just standard passthrough charging it can function as a uninterrupted power supply. I dig the screen has each port’s voltage, amperage and watts. It’s a true USBC nerd’s power bank.

This is a big, solid battery. I have not tested the capacity on this, but given the size and build quality, I believe it probably does have 25,000 AH. I believe it probably needs a specific charger because the 4 port Anker charger I have doesn't charge very fast. I usually by Anker products but this is my second non-Anker battery.

nice power storage and i like the power draw displays on the front

Quality as described

Edited June 24, 2025: My first impression of this power bank was of significant concern, due to noticing it trying to draw more power than my charging block was rated for (24W vs 20W), resulting in the bank not charging, and the charging block becoming extremely hot. After shifting to different cords and blocks, I was able to get the unit charging properly, and then had a fantastic vacation using it as my backup to charge phones, watches, etc. flawlessly. I’ve been in touch with customer service, and I believe they’re working on troubleshooting the issue. I was able to get it working properly with charging blocks from other manufacturers, but I’ve now also paired it with a Cuktech 100 W charger, and it seems to work flawlessly. I’m very happy with the purchase as a whole, and how the unit functions, with the exception of the very odd electrical and heat issue initially. I still think that it would be very important to either come with an appropriate charging block, or at least have a bundle option or recommendation, etc.

Perfecto! No podria agregar otra descripción para esta beteria. Potencia, rapidez y seguridad. No vas a tener ningún problema con esto donde sea que lo lleves. Si quieres cargar rápido nuevamente esta bateria puedes usar un cubo de 45w y lo tendrás listo en menos de 2 horas.

This was written 01/2025: I'm not here to badmouth this item. It did what it was supposed to do. However, when I received mine out of the batch, we had good times for a couple days. Then it did the weirdest thing. It showed it was charging with no cables attached. So I rebooted the battery, and it did it again. So off to refund you go! Don't be fooled by reviews. Go with Anker, something familiar and reliable. 1 star. Updated review 2/2025: I was shipped a defective charger. Cuktech reached out to me and offered a free replacement. Being that we're in the era of future and evolving technology, I decided to take their offer. The new charger was shipped to me pretty quickly. It works just as it says it would. Plus, you need at least two of these if you have alot of battery-operated devices you carry around daily. So, to finalize this review, if you want a cool device that charges all your crap and you're a gadget person who just has to make sure everything is charged all the time, this is the one stop shop for you. On top of that, you have great customer service that reaches out to help if you need it. They are courteous and timely when it comes to solving technical issues with their products. 25,000 can ya hear me?

Mine came broken. Wouldn’t receive a charge at all. No matter what kind of charging brick I used. I tried my 140w fast charger usb c to c. And even the 100w port on my power station and still wouldn’t charge. And yes I was using a usb c cable rated at 100w.
