CUKTECH 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.

This charger is exactly what I needed for my ROG Ally Z1 Extreme. It delivers consistent power without overheating, and it charges fast even while gaming. Super compact and reliable – I’ve had zero issues with it so far. Great build quality too, and it fits easily in my travel bag. If you have a ROG Ally, this is a solid choice for keeping your device powered up without any worries.

Great product, I wish the type c was the same output. I can get one of my devices plugged into it and it worked. But the other type fee it won't power up. Not a big deal breaker but irritating to me. It does take a long time to charge, I connected to a 100 w charger using a 100 w charging cable and it still takes a couple hours just to give it to the 80s percentile. However it bust out a lot of power, it'll laugh my one device damn near the whole day, I think it's doing 15 volts at 2 amps.

In a world of terrible battery banks, this one stands apart.. It’s does exactly what they say it does.Build quality is good. I’ve dropped it a few times and it’s fine, no dings or evidence that it will have durability issues.Charges iPhone SE about 5 times. I think ot charges 50% in 30 minutes. .Charged my laptop most of the way in about 90 minutes.Only warning - not a convenient shape for most pockets.Will update if anything changes.Review written after 1 month daily usage.Definitely a good deal if there is still a coupon and probably worth it no matter what.

Won't charge anymore after 2 months of very little usage. The battery held very long but not being able to recharge makes it useless. I tried using different charging cable and charging adapters. Contacted seller with amazon receipt. No response after 3 business days.Edit: cuktech support was able to contact me once they saw the review. I think it might have been an issue with the support link and not the company. They reach out to gather some information from me and promptly sent replacement.

Honestly not bad for the price, it is a bit on the heftier side and weighs a good amount but nothing super crazy. Charging speed is great, it holds charge for days without moving a sliver on percentage. it charges very quickly and efficiently, being ready within 1-2 hours from 0-100. Would recommend!!

Excellent power bank. Great to have around for emergency charging

Product is good, but it is much cheaper to buy the same thing in China.
