15 SE Power Bank 20000mAh 65W Laptop Charger, 3-Port USB C Portable Charger, PD 3.0 Fast Charging External Battery Pack for iPhone 16/15/14 Series, Samsung, MacBook, Dell, Steam Deck, and More

The Best Travel PoweAfter ordering and testing several highly-rated power banks, this CUKTECH 15 SE 20,000 mAh Power Bank is hands-down the best of the bunch for my needs—and I’m very picky. What I was looking for: • ✅ Airplane safe – At 20,000mah, it hits the maximum battery size for the FAA limit and is totally fine for carry-on. No more worries at security or the gate. • ✅ True pass-through charging on every port – This was a dealbreaker for me, and most power banks I tried only allow it on one port, maybe. It also significantly slowed down the charge and the output. With this one, I can charge the battery and still draw power from all ports at once - all at full speed. That makes a huge difference when traveling and trying to keep everything topped up. • ✅ Fully powers my MacBook Pro – I’ve run it as my main power source while working remotely, and it keeps up without a hitch. • ✅ Daisy chains like a champ – I’ve successfully used it in a multi-device setup: powering my MacBook, charging an external battery, running an iPad and phone—all through different ports—without issue. This thing handles complex loads like a pro. Build quality is solid, charging speeds are fast (tested and hit up to 65 W per USB‑C port), and the digital battery display is a nice touch, although i wish it showed wattage not just percentage. The only things I wish it had: a built-in AC wall plug and built-in cables. Those would make it absolutely perfect. But even without them, this is still the charger I’m keeping and traveling with. Everything else I ordered is going back. If you’re looking for a compact, carry-on-compliant, high-output power bank that just works—and lets you charge multiple devices and itself at the same time at a reasonable price—this is it. Next comparable thing is the UGREEN Nexode but it's twice the price.

The Cuktech 15 SE power bank has plenty capacity to charge my devices plenty fast. For its capacity the size and weight are very reasonable. The Cuktech 15 SE can be used as a mini/temporary UPS, which I’ve been doing for the past few months. Many power banks offer pass through charging, but if the power goes out, it may momentarily stop charging. However, this power bank does not, so it can be used as a UPS of sorts, and with its 20k mAh capacity, it can power devices for a long time during power outages. Build quality is good, and I haven’t had any issues so far running the power bank 24/7 over the past few months. Highly recommended!

No complaint in my usage for more than half of a year. It is not the lightest 20000mAh power bank. Actually, it is the heavier one. (Cuktech themselves have lighter ones, at higher price). 488g/17oz. Aside from the weight, I had zero issue with it. Super sturdy, never get hot, good performance until the last bit of charge (generally you should avoid that, some power bank will lose some capacity permanently if you drain them to the last bit of charge).

So far so good. Comparable to my old 20k chargers in weight and dimensions, but charges very quickly. The only downside so far is the low power charging toggle for my dac or my earbuds. For a literally quick top up, its doing great so far. The name is odd, but luckily I haven't had too many people take notice enough to give me 20 questions. 2 USB-C's and a USB A are great for flexibility. The higher watt model was also tempting, but this is a good Goldilocks zone.

I own a few power banks, and this is my favorite. It’s a little heavy, but it quickly charges devices. It transfers enough power to charge my MacBook and my son’s Nintendo Switch 2. My son always has to have his Switch with him, but I was having trouble finding a power bank that could charge it. I was very pleased to have found this to him to use.

I bought this to power a USB soldering iron to reduce having to take my Hakko soldering station with me to customers. The 65W/20000 mAh is MORE than enough to power the iron to 700-800F for hours without issue. I purchased this because I liked the form factor of this "cube" vs. the typical cell-phone brick offerings. This is not light, as I hope customers would understand given the mAh size, but it's not a brick either. It was about 60% charged, and I was actually VERY surprised that it charged to 100% in under an hour. This is MUCH faster than the older power brick I had for our cell phones, and much smaller capacity. Don't be a cuck. Buy a cuktech today ;)

Battery capacity has dropped of significantly after just a few weeks of use. It now only lasts my laptop about 3 hours from a full charge. Based on the advertised mAh it should last 8 hours or more. -- Update: they gave me a 30% refund and explained more about the product which was very kind

It's a solid battery bank. I've used it to charge up my Macbook Pro. No fancy Bluetooth features that you need an app for. This is just a basic battery bank with a display to show you what percentage of charge it holds. I think it's about as heavy as a regular soda can, and can fit easily into a carry on bag.

Comprato circa 1 anno fa, INDISTRUTTIBILE, mi sarà caduto più di 20 volte, e dato che ha dimensioni e peso notevoli ha sempre recato danni a parquet e mattonelle ma non si è mai rotto! Si ricarica in qualche ora e poi mi dura giorni, con una sola carica riesco a caricare il telefono due volte e anche l’iPad “partendo da 0” in tempi record! miglior powerbank mai comprato nella mia vita, consigliatissimo🤟🏻
