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

Nice made, decent weight, long lasting and looks high end finish. The charging is fast. I use it as a backup battery for my dashcam. 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
