5 back-to-school gadgets under $50 I recommend to every student (and how they come in handy)

When I was in college, I used to carry at least two wires for my charging and data transfer needs. More often than not, using them was an irritating experience because I had to spend time untangling them. If you're disorganized like me, the Nomad ChargeKey will be of huge help. It is a compact USB-C to USB-C cable that can be housed in your keyring, so you're never out of a high-quality cable. 

Also: I never leave home without this viral USB-C key ring accessory, and it only costs $25

The Nomad ChargeKey is a 240W USB-C cable that can quickly charge mobile devices and offers fast 10Gbps data transfer speeds. So, you don't have to rely on outdated tech on your latest MacBook Air for reliable and snappy data transfer. This compact cable is built to last, thanks to its electroplated zinc build on both the cable housing and the little connecting lock.

The Baseus PicoGo AM31 is a small but feature-rich power bank built for Apple's MagSafe charging. I carry it everywhere because it easily fits in my jeans pocket. The 5,000mAh battery capacity is enough to charge your iPhone at least 1.5 times, which isn't a massive number but can come in handy when you're running low on battery between lectures. 

This Baseus power bank features a built-in kickstand to prop up your phone when you need to consume content. It supports 15W Qi2 and 20W fast charging. With the new Pixel 10 series rumored to add Qi2 charging standard, it will gain magnetic charging support for more non-Apple devices soon. And if your phone doesn't have magnets or wireless charging, the Nomad ChargeKey dangling on your keychain is there to come in clutch. If you have a bigger phone, there's another slimmer but larger Baseus power bank for $20.

An AirTag can be a godsend in certain unwanted situations. If you regularly are misplacing your things, like your wallet, bag, or keys, I strongly suggest getting one for your belongings. Now retailing at $25, it is one of the best long-term investments you can make. If you're an Android user, the Chipolo Pop is a great alternative with Google's Find My Device network support.

As for the AirTag, it uses a built-in U1 ultra-wideband chip for Precision Finding and Apple's extensive Find My network to find your missing items. This coin-sized item tracker is also ZDNET's pick for the best Bluetooth tracker overall for its UWB-powered precision tracking, replaceable battery, and access to Apple's widely supported Find My network. 

The Sony WH-CH520 wireless headphones aren't as jam-packed with cutting-edge technology as the CH720 cans but are still ideal for casual listening. They are great for everyday use, thanks to their light design and comfortable on-ear fit. Plus, they're now down to $38, which is an unbeatable value for Sony's sound.

These are best for students who want to enjoy their music and still be aware of their surroundings. Due to their on-ear design, more ambient noise can be heard, as opposed to over-ear headphones. You'll get up to 50 hours of battery life on a single charge, and when low on power, they can top up within five minutes for 90 minutes of playback.

I have one more audio item on this list because ambient music is important. In fact, Sonos' Music Makes It Home study says listening to music out loud makes doing chores easier, and college life can involve a lot of chores in the dorm room. The $40 Amazon Echo Pop is the perfect companion for ambient music.

As compared to other Bluetooth speakers, the Echo Pop is smarter and can add more convenience with Alexa Skills. It is compact and yet loud enough for a room. It has gone down to $25 in the past, and if you spot it at that price, it's a good idea to get one.
