I want fewer cords, faster charging, and a backup plan that actually keeps up. Right now, CUKTECH's 15 Ultra Power Bank is on sale for $85.19 at Amazon — that’s 29% off its usual $119.99 price with a 20% coupon applied at checkout. It's easily one of the better deals I've seen on a power bank that isn't just pretending to be high-powered.

This one puts out up to 140W via PD3.1, which means it’s not just for phones. I’ve used it to top up a MacBook, charge a Steam Deck, and still have juice left to keep my phone alive. It’s also smart enough to show what it's doing, thanks to a sharp 1.3-inch TFT display. You can actually see what protocol it's using and whether it’s cooking or coasting.

I think my favorite feature is its ability to recharge itself at 165W in Beast Mode. You get 70% charge in 20 minutes, which is great if you’re the kind of person who packs five minutes before heading to the airport.

Specifications:

• Price:$85.19 $119.99

• Retailer:Amazon

• Battery Capacity:20000mAh

• Output Power:Up to 140W PD3.1, 165W total input

It works with all the charging standards that matter: PPS, QC, PD3.1, FCP, SCP, and MiPPS. And yes, it includes a 3.2-foot cable that actually supports the full power output — not one of those afterthought cords that melts under pressure.

In my opinion, most power banks are either big and slow or small and underpowered. This one manages to be neither, and now it’s under $90. If you travel with more than one device, this is the kind of thing you’ll be glad you packed.
