CUKTECH25000mAh Power Bank, 165W USB C Laptop Portable Charger, 3-Port Output Battery Pack with Built-in USB-C Cable, Fast Charging Power Bank for iPhone, iPad, MacBook, Samsung, Dell, HP and More

This portable charger has exceeded all my expectations and then some! It has effortlessly charged everything from a gaming headset to a MacBook Pro M2 14-inch, making it an incredibly versatile power bank.If your phone supports fast charging, this charger will power it up even quicker than usual. Despite its large 20,000mAh capacity, the size and weight are completely reasonable for the power it delivers.If you need a reliable, high-capacity power bank for all your devices, this one gets my full approval.

My wife and I use this constantly! It takes a little while to charge, but holds that charge for a long, long time. Great battery!

Such a good unit holds a charge while in storage for a long time. We put it thru it's paces on vacation on a cruise and several flights and it's just under the TSA limit for a large power bank .

The thing works great overall and I have no complaints with the size of the battery compared to cost. It charges cellular devices extremely fast also. My only complaint is the display which lights up townhouse battery percentage as it’s draining when you have a device plugged in - there does not appear to be a way to turn off the display which is incredibly annoying while charging a device in the dark while trying to sleep or when I’m rocking my baby to sleep and you keep seeing an annoying bright white flashing light showing the remaining battery percentage. This is the reason I took the overall rating down to 4 stars. I can’t stand the annoying light.

Worked as described

It's a monster. This thing doubles as a dumbbell. It's a brick of power at your disposal and as a weapon. It lasts nearly forever, and we only have to plug it in once a week or so. It seldom drops below 50%. It also works well with solar charging with a separate (not included) 5v panel. It'll fill in during the day so you can party at night. Overall, it's a great addition if you're strong enough to carry it.

I have a few power banks for my phone, but this one is big and strong enough to power my laptop. It does take a while to charge the bank up, but it's great back up power for when I am unable to plug my laptop into the wall. This is can probably charge other devices as well but my main purpose was using it for my laptop, and it works perfectly.

This is the only power bank I’ve tested this year that can simultaneously Super-Fast charge 2 Galaxy phones and Fast charge a third. No other power bank I’ve tested can Super-Fast charge more than one device at a time. While that is a significant product differentiator, I struggle to justify the price premium (~$100 with coupon) at the time of the review for a 25,000 ma power bank.Power bank Charging:Charge time was OK at about 2.5 hours from 0 to 100% when using a 65 watt charger.Device Charging:The product is rated at 25,000 ma and was able to fully charge a S24 plus (4900 ma) phone 3.2 times for a real-world conversion efficiency of 63% which is decent capacity performance but short of the most efficient power banks I’ve tested this year.This power bank charged a S24+, S21+ 5G, and a S22 plus simultaneously. The two phones plugged into the USB C ports Super-Fast charged and the phone connected to the USB A port Fast Charged.This power bank charged a Dell Mobile workstation but the laptop indicated a slow charger was connected. And the power bank is only the second I’ve tested that will charge a Galaxy Book Flex laptop. There is something with how the Flex auto negotiates with power banks that errors out and doesn’t charge the laptop. This power bank does not have that issue.
