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. Read more

I'm very happy. I bought it because there's a planned power outage in my building on one of my work from home days. I've tested it a few times now and I'm confident it will keep me powered up the 9 hours I need it. I'm about to buy another so I can keep the cats' fountain going. Read more

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 ;) Read more

It’s a little outdated product but the battery, charging and info display are all at premium level. It comes with a cable and a pouch bag for storing it, it’s a little heavy though Read more
