The speaker has been rated for 20 hours of playtime, plus it supports Wireless Stereo Pairing, which allows users to connect two speakers to each other for richer output.

Sony has some solid midrange headphones in its catalog, and one of the best is the WH-CH520. They're lightweight and comfortable with an on-ear fit that lets in some ambient sound. The pair also offers excellent battery life, lasting up to 50 hours on a single charge. Right now, every color is on sale, from the standard blue to the more muted cappuccino brown.

Apple's AirTag is the best small accessory you could ever buy, especially if you tend to misplace things. The new generation improves on the original by including a louder built-in speaker and wider tracking range. Battery life is still stupendous. It's capable of lasting a year straight on a single battery.

Electric toothbrushes are severely underrated. They can better target plaque in those hard-to-reach places. This Philips model features a pressure sensor to protect sensitive teeth and gums. Don't worry if you forget to recharge the toothbrush. Philips' device can last two weeks on a single charge.

There is another version of the Sonicare 4100 that comes with additional brush heads inside a plastic case.

Ever wondered what your pets are up to while you're away? The Blink Mini 2K+ indoor camera makes it easy to check in from anywhere. Like the name suggests, the device records in 2K resolution. It features motion detection to automatically start recording when something moves in front of it, night vision to see in low-light conditions, and a wide field of view.

Digital notebooks like the Rocketbook Core are clever devices. You jot down notes on its reusable pages with a special pen, scan your writings using the Rocketbook app, and then wipe the pages clean with a cloth so you can use them again and again. We're recommending the Rocketbook Core in particular because of its size. At about 6 x 8.8 inches, it's compact enough to fit easily in backpacks, purses, and briefcases.

The JBL Go Air Pop+ are among my favorite earbuds I've ever owned. In fact, I own a pair myself. They sound great with strong bass output, they're comfortable, and they last a really long time. According to the official Amazon listing, the earbuds can last over 35 hours on a single charge. There are six color options currently available, but only have are on sale: Rose (red), Nacy (blue), Pink, Slate (gray), and Teal (green).

I don't know about you, but the standard two-outlet wall setup just isn't enough, especially if you have a lot of gadgets to keep charged. A power strip works, but it's easy to trip over and kick. That's why I recommend the QINLIANF 5 Outlet Extender.

It plugs directly into your wall outlet and expands it into five individual outlets. The device comes with 1680J surge protection to guard against sudden power spikes. I recommend grabbing the version with two USB-C ports and two USB-A ports.
