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

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

I use it every day, dose exactly what it's supposed to, nothing more, nothing less. I love the screen to view the incoming and outgoing data. If you are a data nerd like me you will love this.

Awesome and powerful power bank,the screen is beautiful and the company behind the product is great! I just got a message from them with important tips to keep this power bank at its best!

Excelente producto. Carga super rapido y es muy fácil de usar. La carga rinde para bastante!

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.

Es buen producto buen material bonito potente vale pena Ami me gusto mucho estoy contento con este producto

I received the item today. Display works. Item seems to be dead on arrival at 0% still after 2 hrs of charging. I tried using several chargers to charge this thing. Can’t recommend this battery at the current moment. Sad to say because this looked like a great battery bank.Update 08/07/2025: Ordered another one out of curiosity and the first one I ordered seems to have been a return. The second one I received came with a brown box to protect the retail packaging and the inner retail package came shrink wrapped. Amazon or the retailer might be putting returns as new.08/09/2025 Update 2: Company reached out in a timely manner and fixed the issue. I give the company high marks for responding quickly in a timely manner.08/11/25Initial impressions: Decided to purchase this large capacity power bank for my MacBook Pro and Steam Deck. Love the display with metrics for data nerds. It’s important to monitor these metrics because some electronics are sensitive and can damage them.It shows real‑time battery level, voltage, current, and offers animated light strip for charging status (flashing up means it’s charging the power bank and flashing down means the bank is being discharged).Only downside it’s appropriate sized for the amount of power available. Not really a power bank that is used to put in your pocket while charging your phone. Only wish this battery bank would show cycle count.

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?
