Spring savings events, like Amazon's Big Spring Sale , are getting started, and it's my favorite time of year to make practical purchases that can upgrade your everyday routine.

From Bluetooth trackers and accessories to cables and more, there's a lot of tiny tech to consider.

Reviewers at ZDNET have tested more than a few of these mighty yet miniature options, including our in-house gadgeteer, Adrian Kingsley-Hughes, and me.

These are some of our favorite pocket-sized gadgets that you can shop right now -- and some of them are on sale.

Reviewer Adrian Kingsley-Hughes finds it handy and convenient to have a screwdriver, scissors, and a pair of pliers close at hand, but says most multitools are a no-go at airports and on commercial aircraft, often confiscated.

That's why he likes the TSA-friendly NexTool Mini multitool.

It has no blade and features needle-nose pliers with wire cutters, tiny scissors, a bottle opener, a SIM extractor, and Phillips head and flathead screwdrivers.

There's also a handy keyring for attaching it to your keys.
