Twenty bucks may not look like much, but you'd be surprised at what you can get for that small sum of money. We live in a world where you can get a cheeseburger for $ 1, a working computer for $ 5 and thousands of high definition movies for $ 10 – so it's obvious that you should be able to pick up some sweet gadgets for less than the cost of a taxi. In this article, we've discussed some of the best technologies below $ 20 so you can play without breaking the bank.

If you can slightly increase your budget, we've also prepared a list of the best technologies below USD 50, and the best technology below USD 100.

Amazon Dash buttons (at $ 5)

To be honest, these things are totally unnecessary. You do not have to own them – but they are also damn comfortable. If you do not know Dash Buttons, here's the scoop: it's basically physical physical buttons connected to the internet that you can connect to your Amazon account and put in your home. When you press a button, a specific product will be automatically added to your Amazon shopping cart. You can buy them virtually for every product you consume (and you have to regularly refill it), making it great for thin toilet papers, laundry detergents, soap dishes, dog food, toothpaste, diapers, and even snacks such like Goldfish or RedBull. Definitely not you need these things, but damn it, if they are not nice!

A welder for welding liquid plastics (12 USD)

Forget about super glue. Instead of accidentally squeezing the glue out of the tube, Bondic lets you combine the two materials together with the liquid plastic that hardens under UV light. Do you know these small UV-glue guns that dentists use to fill small cavities before they get too serious? It is basically the same gluing technology, only slightly modified and changed for a different purpose. It must have if you tend to break the sunglasses frequently

Qi wireless charger ($ 15)

Still connecting the phone to the juice up the battery like a caveman? Stay with the times, brother! Get yourself a Qi wireless charger and free yourself from the shackles for the life of the wires. Put one of these suckers on the bedside table and put a phone on it before you go to bed. After waking up you will have a fully priced phone that you can simply grab and slide into your pocket – without having to disconnect (because, you know, it's so uncomfortable!). Seriously, however, wireless charging is one of those little things that simply make life easier, and you do not realize how great it is until you have it.

Dremel wireless tool ($ 20)

[1945940]

If there is one electrical tool that everyone should own, it is Dremel. It's basically a Swiss army knife from the world of power tools. Thanks to the right fixings, these machines can do practically everything – cutting, grinding, polishing, sculpting and everything in between. This kit contains a small set of attachments to get started, and if that's not enough, the tool is compatible with the gazillion more attachments that Dremel does. Be careful though. Power tools are a slippery slope, and Dremel is a goal drug. If you are not careful, you can wake up for a year using a table saw and a laser cutter in the garage, wondering where your life went.

A smart plug compatible with Alexa (13 USD)

Have you ever wished that you would live in one of these futuristic smart homes where you could shout "computer, turn on the lights!", Would it be magical? If so, we have good news for you. While setting up a voice-activated intelligent home was once difficult and expensive, nowadays it can be cheap and easy. An example? Smart GoSund plugin. Although it is scandalously cheap, this clever little IoT plug adapter is compatible with Alexa – which means you can connect virtually everything to it, and after some settings, you can turn the device on or off just by shouting at Amazon Dash / Echo / anything.

Bluetooth stereo adapter (USD 14)

Do you have an older stereo that is not compatible with all new streaming technologies, and you have enough to leave your phone tethering the auxiliary port? Do not worry – this little key is here to save the day. Just connect it to the auxiliary port in your home or car stereo and pair it with your smartphone. When everything is ready, you will be able to hang audio on speakers from any application on your phone.

Sandisk 32 GB MicroSDHC Card (12 USD)

If you can expand the memory of your phone (sorry iOS users!) And want to do it cheap, SanDisk is the best choice. With 32 GB of memory, you can store over 11,000 photos and compress 480 hours of movies with a standard 8-megapixel mobile phone. Of course, you can use this card for many other things (action cameras, digital SLRs, etc.), but if you plan to take RAW pictures or high FPS video, you'll probably need something with a faster write speed.

Google Cardboard ($ 15)

Virtual reality is still relatively new, but with over 10 million copies sold, Google Cardboard is one of the most popular VR sets. Do not be fooled by outside enthusiasm: you will find a lot of fascinating entertainment inside this piece of cardboard. You can watch football matches live, YouTube videos, and even stand next to Paul McCartney when it performs on stage. The best part is that all you need is an Android or iOS phone with the right software and everything is ready.

Sony ZX110 headphones ($ 20)

Decent headphones usually cost a pack of cash, but the Sony ZX110 headphones are a rare exception. Despite the fact that they cost as little as $ 11, the bad ones suck the sound that will embarrass your Apple headphones. Foam cushions provide the much-needed listening comfort during long listening sessions, while the Acoustic Bass Boost technology from Sony provides you with a lower level than most earbuds. For less than USD 20, you can not see a range of headphones better than the Sony ZX Series.

Wireless keyboard Logitech K360 (20 USD)

Logitech usually offers elite wireless keyboards, and the K360 is not different. The elegant keyboard is compatible only with some versions of Windows, but it is full of versatility. It is equipped with six shortcut keys for playback, pause, previous playback, next playback, volume control and mute – all this makes interaction with multimedia much simpler. You can also customize 12 programmable F keys to get quick shortcuts to your favorite websites, applications and almost anything you want to get on your device.
