Question 1

Is the CUKTECH 45W Power Bank compatible with the latest iPhone 16 and Samsung Galaxy models?

Accepted Answer

Yes, it works with almost all USB-C devices. Many reviewers confirm it fast-charges iPhone 16/15/14 and Samsung Galaxy S24/S23 series. It also supports MagSafe cases without interference. For older micro-USB devices, you’ll need an adapter.

Question 2

How long does it take to fully recharge the power bank itself?

Accepted Answer

With a 45W USB-C charger (not included), it reaches full capacity in about 2.5 hours. Using a standard 20W charger takes closer to 5 hours. A few TikTok users noted that using a lower-wattage brick significantly slows things down—so grab a fast charger.

Question 3

Can this power bank charge a laptop like a MacBook Air or Dell XPS?

Accepted Answer

It can maintain battery levels on smaller laptops during light use, but it won’t fully fast-charge a 13-inch MacBook Air from zero. Most users find it best for phones, tablets, and Nintendo Switch. For heavier laptops, consider a 65W+ power bank instead.

Question 4

The built-in USB-C cable seems very short—can I use a different cable?

Accepted Answer

Absolutely. The built-in cable is designed for convenience, but you can also charge through the USB-C output port with your own longer cable. Many YouTube reviewers suggest this workaround if you need more reach during travel or in-bed charging.

Question 5

Is this power bank allowed on airplanes?

Accepted Answer

Yes, the 20000mAh capacity (74Wh) is well under the 100Wh limit for carry-on luggage. Plenty of travelers on Reddit confirm it passes TSA security without issues. Just keep it in your carry-on, not checked baggage.
