Why we love this deal

Amazon's Prime Big Deal Days event sale is live through Oct. 8, making it a great week to shop for all those important purchases you've been putting off all summer. Fall's here, the holidays are just around the corner, and there are some incredible savings to be found on electronics, furniture, autumn clothing, and other exciting categories. Some of the best limited-time deals that popped up this week are exclusive to Prime members, so it's a great time to try out an Amazon Prime subscription if you don't have one already.

One of our favorite tech deals right now is the Anker PowerCore Slim 10,000 Portable Charger, currently going for its lowest price ever at 40% off. Normally priced at $26, Prime members can get it for just $16 during this week's October Prime Day deals event.

Why do shoppers love it?

One of the biggest draws with this power bank is its travel-friendly portability. Many other brands and models warn that their chargers aren't airline-approved, but that's thankfully not the case here. It may take a fair bit of time to fully recharge the bank between trips, but then it's ideal for quickly topping off your phone, tablet, or other USB-C devices. It also fits neatly into your carry-on luggage or USB-equipped suitcase, so you can even use it for a quick, convenient charge while you're 30,000 feet in the air.

"What a lifesaver. I used this almost every day on a six-week trip to Europe," said one reviewer. "This power bank saved the day. I was able to stay out late because I had the peace of mind in knowing I could recharge my phone; it had enough power to charge both my phone and my husband's, with half the battery still remaining at the end of each day. I don't know how we would've gotten by without it."

Details to know

• Bundles available: You can buy this charger individually or in a $34 two-pack.
• Color options: The power bank comes in black or white, but you'll pay about $3 less for the black version.
• Capacity: 10,000 milliamp-hours. In practical terms, this comes out to roughly two full charges of a depleted iPhone battery.

This slim, pocket-sized charger features Anker's PowerIQ and VoltageBoost technology to ensure fast, efficient charging of your most critical devices, while also offering a trickle-charge mode for things like wireless earbuds, Bluetooth speakers, and so on. The power bank comes with a USB-C charging cable, a brief user manual, and an 18-month manufacturer's warranty.

You can't use both input ports at once, but the portable charger's 10,000-milliamp-hour battery holds enough juice to offer two full charge cycles for your iPhone, nearly two charges for your Samsung Galaxy S23, or about 1.2 charges for an iPad Mini 6. If you think you or your partner might need a second power bank on your travels, there's also a handy two-pack available for $34.
