The CUKTECH 15 Ultra strikes a great balance between raw power and portability
CUKTECH 15 Ultra Power Bank The CUKTECH 15 Ultra Power Bank strikes a perfect balance between power and portability. It has a nicely sized 20,000mAh battery, fast charging speeds at 165W of output, three ports, rapid recharging with two input sources, and a stylish design. After testing a wide variety of battery packs, I often find myself craving something more balanced. Smaller ones are very convenient to carry around, but are never powerful enough. The bigger ones get the job done, but they can be a bit too hard to carry around. The CUKTECH 15 Ultra Power Bank offers a nice proposition, offering something right in the middle. It aims to find a balance between true portability and power. Does it accomplish it? I've been testing the CUKTECH 15 Ultra Power Bank for a couple of weeks and am ready to tell you whether it makes the cut. Let's jump right in. Stylish and sturdy Edgar Cervantes / Android Authority Of course, the first thing you notice as you unbox anything is its design and build. This is especially important when dealing with a battery pack, which is an accessory you will see and show off everywhere. You'll also carry it around, which means it will undergo quite a bit of torture, so you need to make sure it will survive anything you put it through. I previously reviewed the CUKTECH 20 Power Bank, which looks cool and offers a sturdy construction comparable only to the best. It has survived months of continuous use, rolling around my trunk, and keeping my devices charged wherever I go. CUKTECH power banks blend style with substance, and the CUKTECH 15 Ultra meets that standard. I am happy to report that the CUKTECH 15 Ultra lives up to the same standard as the 20. While smaller at 5.98 x 2.25 x 1.75 in, and made of plastic, it by no means feels cheap. The construction seamlessly blends into a solid little brick with zero moving parts, no wiggling ports, and a singular button with a solid click. Edgar Cervantes / Android Authority It is a little on the heavier side at 1.3 lbs, but it doesn't feel uncomfortably heavy. Instead, it feels like the kind of heft that equates to quality. It's a balanced weight, similar to carrying a gold coin. It just feels satisfyingly heavy. And I mean, the weight makes sense when you consider this thing carries 20,000mAh of battery capacity. You won't really feel its weight if it's just in your backpack. It does fit in my pants pockets, though. And if you plan to carry it around in your pocket or in a small purse, the weight will definitely be more noticeable. Enough battery for a couple of days In my experience, the CUKTECH 15 Ultra lasted me a couple of days on the go. I went to San Diego for the weekend (Saturday and Sunday) and came back home with a dying battery pack, but during that time it managed to juice up my smartphones (a Pixel 8a and an iPhone 15), smartwatch, and my wireless earbuds. I would usually charge everything at night, and recharge the phones on Sunday afternoon, during my drive back. Edgar Cervantes / Android Authority Considering the 20,000mAh battery capacity, this level of usage makes sense. It's a great little battery for commuters, quick weekend campers, or mobile device backup during power outages. Of course, your mileage may vary, depending on what you power, because this thing can charge more than smartphones and mobile accessories. Super fast charging speeds Edgar Cervantes / Android Authority Considering the size and price, the CUKTECH 15 Ultra bank is super powerful. It has a max output of 165W, though none of the ports can reach that mark individually. The CUKTECH 15 Ultra Power Bank has two USB-C ports and a USB-A connection. Based on my tests, the one labeled 'IN1/OUT1' can reach 140W, while the 'IN2/OUT2' one maxes out at 65W. The USB-A connection is slower at 18W. Of course, these max speeds are only achievable when charging one device at a time. Speeds get slower as you plug in more gadgets simultaneously. To put things into perspective, the 140W port is powerful enough to charge most tablets and laptops. I have also used it to charge portable speakers, my mirrorless camera, and a portable coffee maker. Chances are that if something uses a USB port, this battery pack can power it. Edgar Cervantes / Android Authority This is because it supports Power Delivery 3.1 and PPS standards, which means it can fast-charge most devices. For reference, even some high-end smartphones like the Samsung Galaxy S25 Ultra are limited to 45W, but this is among the fastest-charging mainstream phones around. The fastest-charging device I have right now is the Xiaomi 11T Pro, which can reach a whopping 120W. Recharging is blazing fast, too Edgar Cervantes / Android Authority OK, so this is likely my favorite feature on the CUKTECH 15 Ultra. Both USB-C ports can work as inputs at the same time. CUKTECH calls this 'Beast Mode Self-Charging.' It pretty much makes both ports work together to reach a maximum of 165W of input. So yeah, it can take in just as much wattage as it can output. With Beast Mode Self-Charging, the CUKTECH 15 Ultra reaches a mighty 165W input for recharging. I never saw it reach 165W, but I was able to consistently recharge it at over 150W, and when it does, it's incredibly fast to fill up. It was recharging at about 1% per 20 seconds or so during its fastest moments. Of course, it will eventually slow down to control the battery's heat, but it is still pretty impressive. So, if you often find yourself in a rush to catch a quick charge, this is the fastest recharging power bank I have tested. It's honestly kind of unbelievable. The only caveat is that you will have to carry a couple of cables. And unless you have a really capable multi-port charger, you will also need a couple of fast bricks to reach such speeds. Should you buy the CUKTECH 15 Ultra Power Bank? Edgar Cervantes / Android Authority Overall, I am really enjoying using the CUKTECH 15 Power Bank. It's enough to keep my mobile devices charged over a weekend (two days), all without reaching for an outlet. Of course, it will die much faster if you start using it with tablets or laptops; in that case, it might not even last one day. That said, I purposely didn't charge it during my short trips because I wanted to test how long it lasted. I could have plugged it in from time to time, and it charges really fast, giving you 70% in just 20 minutes when using Beast Mode. With a bit of effort regarding recharging the battery, I could have made it work for longer, or used it with my higher-power devices without much of an issue. The CUKTECH 15 Power Bank hits the sweet spot for power, design, and price. After a couple of weeks, I find myself gravitating more towards the CUKTECH 15 Power Bank, just because it is plenty powerful for my everyday use and is easier to carry. The CUKTECH 20 just lives in my car these days, just in case I need more juice, but I haven't really needed to use it so far. At $109.99, the CUKTECH 15's price is pretty fair for a power bank of this caliber, with rivals like the Anker Prime 200W ($129.99 at Amazon) going for $30 extra. Not to mention, discounts are pretty common. If you need more power, though, and don't mind carrying something larger and heavier, the CUKTECH 20 Power Bank ($119.99 at Amazon) is a nice upgrade. As for me, the CUKTECH 15 Power Bank will continue to be my daily go-to. It's just enough power and speed, and the smaller ones usually leave me wanting more. I think this one hits the sweet spot. CUKTECH 15 Ultra Power Bank MSRP: $109.99 Recharges like a Beast. With up to 165W output, a stylish and sturdy design, and rapid Beast Mode Self-Charging, the CUKTECH 15 Ultra is a great choice for a 20,000mAh power bank. See price at Amazon Positives Great between portability and power Great between portability and power Amazingly fast to recharge Amazingly fast to recharge Quality design Quality design Reasonable price for capacity and specs Cons A bit on the heavier side A bit on the heavier side Would be nice if it had an extra port or two Follow

The handy CUKTECH 15 Ultra Power Bank is at a record-low price!
Edgar Cervantes / Android Authority Do you keep running out of battery? I've been searching for a battery pack that's both easy to carry and powerful, and so far, the CUKTECH 15 Ultra Power Bank offers the perfect balance for my needs. It's at a record-low price, too, and you can take it home for $71.99. That's much more enticing than paying the full $109.99 retail price! Buy the CUKTECH 15 Ultra Power Bank for just $71.99 ($38 off) This offer is available from Amazon, and it comes in two stages. First, there's an automatic 'limited time deal' that brings the price down to $79.99. Then, you can press the Redeem button right below the price to get an extra 10% coupon applied. The CUKTECH 15 Ultra is a really nice battery pack if you value both portability and power. At 5.98 x 2.25 x 1.75 inches, it's smaller than similar competitors, and it weighs 1.3 pounds. This means it can easily fit in most purses and backpacks. I have even carried it in my pants pocket! It has a 20,000mAh battery capacity, which is good enough to charge a smartphone about 3-4 times, depending on your battery size and other factors. For the size, it's a really nice amount of juice. Edgar Cervantes / Android Authority The main highlight of the CUKTECH 15 Ultra Power Bank is how fast it is. It can output as much as 165W. It has two USB-C ports and a USB-A connection. The fastest USB-C port can reach 140W, while the second is limited to 65W. Arguably, though, even the slower port is pretty fast. The USB-A connection can output 18W, which is slower, but more than enough for accessories or slow charging a smartphone. This one has become my go-to power bank, so I am sure many of you will love it. If you're interested, act quickly, as this is an all-time low price, and those don't tend to last long. Extra deal: The Anker Laptop Power Bank is $40.50 off Another popular battery pack at a similar price level is the Anker Laptop Power Bank. It's going for $94.49, which is a nice discount on its $134.99 full retail price. This one is not exactly better in every way, but it has some nice touches many of you will appreciate. It also comes from a more recognized brand, which we know many of you will prefer. The Anker Laptop Power Bank gets a larger 25,000mAh battery, so you're getting an extra 5,000mAh with this one. It also has a max output of 165W. All three USB-C ports can output as much as 100W, so there's no need to pick and choose specific ports here. The single USB-A connection can push out 33W, so that one is also faster than the one on the CUKTECH battery. Dave Carr The other main difference in ports is that Anker has built two of the USB-C connections in. Only one is a standard USB-C port; the other two are integrated cables. One of them is retractable, and the other doubles as a loop, adding a bit of functionality to its ports. This is nice if you prefer not having to worry about carrying cables all the time. I worry about built-in cables, as they are essentially non-replaceable. This means that, if damaged, that port is pretty much done for. I would honestly be worried about damaging these all the time. Anker mentions these are rated for 20,000 bends, though. Also, our co-worker Dave Carr mentions the whole unit feels pretty sturdy. Additionally, it comes with an 18-month warranty.

Paul Jones / Android Authority Power is a precious commodity in the modern age, and nothing seems scarier than a dying smartphone battery.

You have to clip on an on-page 35% coupon, then press Redeem on the extra 10% coupon right below it. If you don't see the second one, the coupon code is 'NHV2N28ZT75S'. CUKTECH 10 Power Bank CUKTECH 10 Power Bank The Cuktech 10 power bank is packed with 10,000mAh of power, multiple-ports, and a maximum output of 100W per port. This power bank is compatible with most fast-charging protocols. See price at Amazon Save $18.00 With Coupon! The CUKTECH 10 Power Bank may not be the biggest, most powerful battery pack around, but it's still pretty capable, and it stands out in the portability department. This measures just 5.63 x 1.77 x 1.33 in. It's often compared to a Snickers bar, so you can really throw it in any pocket. It has a really nice design and a screen that shows the live status of the battery and ports. Packed inside, you'll find a 10,000mAh battery. Again, not the biggest, but that is enough to charge standard smartphones 1-2 times. Of course, this depends on factors like your battery size, whether you're using it while charging, and energy loss. Paul Jones / Android Authority That said, the little power bank is surprisingly fast for its size and price point. It has a max output of 150W across both ports, one of which is a USB-C port and the other a USB-A connection. The USB-A port can only reach 33W, which is actually pretty fast for this standard. The USB-C connection can get pretty fast, though. It can reach as much as 120W, but only with supported Xiaomi phones. Other phones, laptops, and tablets can 'only' charge at 100W using the USB-C connection. At just $21.99, you really can't go wrong here. The CUKTECH 10 Power Bank is super portable, pretty fast, and is built very nicely. And while 10,000mAh may not be enough for more demanding users, it should take most of you through a typical day without an issue. Go catch this deal while you can! It is a record-low price, and we don't see it lasting very long.
