Father's Day is just around the corner (it's on Sunday 21 June, if you're still wondering), so it's time to thank your dad for all the help he's given you over the past year. And what better way to show your dad just how much you love him than with some state-of-the-art technology. Here's a round-up of some of the best gadgets that'll be sure to put a smile on your father's face.

We've got a range of ideas to suit any budget, and we've split them into categories by product type to help you find the gift that suits your dad best.

Last minute Father's Day gifts

With just a few days left, you'll want to check the delivery times if you plan on ordering online. It might be worth signing up for Amazon Prime if you plan on ordering something there, which offers next day delivery. There's a free 30-day trial, too.

Of course, there's always the option of getting a printable or emailable voucher. It's a bit of a cheat, but we know many people who'd be pleased with an Amazon voucher that they can spend on whatever they please, and let's face it, it's a lot better than nothing.

I Want One Of Those is offering free next day delivery on selected Father's Day gifts, including the £15.95 Smartphone Projector (grab some popcorn from the supermarket to make this gift even better) and the £79.99 Sphero Robotic Ball, cooler than a remote control car.

Very is offering free next day delivery with the code 6J6RE if you spend over £50. Choose Standard Next Day delivery at checkout and then enter the code. Very sells lots of gifts perfect for Father's Day, including electrical items and gaming and DVDs. The £59 Skullcandy Hesh Headphones could be the perfect gift for a music-loving dad, for example.

Father's Day Gift Guide: Tablets

iPad Air 2, £399.

If your dad is constantly fighting for the TV remote, enjoys reading news online or maybe enjoys a spot of gaming, a tablet could be a really good idea for a Father's Day present. It's an extra special gift if you live far apart, as it'll open up the world of video calls via Skype or FaceTime.

We'd recommend the iPad Air 2, £399 for a bigger budget, which is Apple's latest 10in tablet, or the Tesco Hudl 2, just £99, which has an 8.3in display and is one of the best budget Android tablets available.  

Tesco Huld 2, £99

Father's Day Gift Guide: Smartphones

Samsung Galaxy S6, £599

Alternatively, if video calls sound like a terrible idea to you, you could opt for a new smartphone and stick with audio-only calls for the most part. There have been plenty of fantastic new smartphones this year, from the budget Motorola Moto G, £150, to the flagship Samsung Galaxy S6, £599, which tops our smartphone chart.

Motorola Moto G, £150

Father's Day Gift Guide: Quadcopters

DJI Phantom 2 Vision Plus V3.0, £899

If your dad already has a smartphone or tablet and you're looking for something a little more fun, a quadcopter or drone would make an awesome present that he'll be showing off to his friends in no time.

Some of these can be super expensive, but there are others that are under £100 and are still great fun. Our favourite is the DJI Phantom 2 Vision Plus V3.0, but that's a whopping £899, so a more realistic option is the £94 WLtoys V666 quadcopter or the £99 Revell X-Spy.

WLToys V666, £94

You'll find even more quadcopters in our best drones round-up.

Father's Day Gift Guide: TV streamers

Roku Streaming Stick, £39

If your dad loves TV and movies, you might find that a media streaming device is a good way to give him access to services such as Netflix or BBC iPlayer without having to fork out for a smart TV. Many also offer additional benefits such as the ability to stream content from a tablet or smartphone, for example.

Our favourite streaming stick is the Roku Streaming Stick, which costs just £39 and even includes a three-month Now TV Entertainment Pass. But there's also the Google Chromecast (£30), which is great if your dad owns an Android tablet or Android smartphone as it can beam video from that device to a big screen.

Chromecast, £30

There are more media streamers to choose from in our 11 best media streamers round-up.

Father's Day Gift Guide: Activity trackers

Fitbit Charge HR, £119

Maybe your dad loves TV a little too much and is hoping to get out there and get fit. Activity trackers can be brilliant motivation to walk to work or go for a jog, and some can also track activities such as bike riding, golf and more if you're dad's into a particular sport.

Our favourite activity tracker right now is the Fitbit Charge HR (£119). It offers real-time fitness stats on your wrist, and the app can tell you your steps, heart rate, miles travelled, floors climbed, active minutes, sleep data, calories burned and more.

Misfit Flash, £39.98

A cheaper alternative with many of the same features is the Misfit Flash, which is £39.98 but does miss out on the heart rate sensor, display and floors climbed data.

Withings Activite, £308

If you're dad's a stylish guy and you've got some cash to splash on him this year, you should check out the Withings Activite. It's £308 but is a really good-looking watch that doubles as a subtle activity tracker with a companion app for Android or iOS.

If you want even more choice, there are 22 activity trackers in our round-up of the best.

Father's Day Gift Guide: Smartwatches

Taking activity trackers a step further are smartwatches, which generally have those capabilities in addition to providing notifications from your smartphone and more.

Apple Watch, £299

For iPhone users, the Apple Watch is the ultimate smartwatch that everyone's talking about right now. You might struggle to get hold of one, but they start at £299 for the base model (and range all the way up to £13,500).

Top of the range for Android users is the LG G Watch R, which looks fantastic and runs Android Wear for notifications, fitness tracking, apps and more. It's available for £229. 

LG G Watch R, £132

The Pebble Steel is a slightly cheaper alternative that we really like. It doesn't have a high-res, colourful screen like the Apple Watch or LG G Watch R, but it does offer retro charm and a brilliant battery life. It's available for £132.

Father's Day Gift Guide: Power banks

Maybe your dad already has loads of gadgets but still loves tech. In that case, why not buy a tech-related accessory such as a power bank. There are lots of reasonably priced, portable power banks available to allow you to add some extra power to your tablet, phone or other device, including our favourites such as the Zendure A2 (£29.95), the OnePlus Power Bank (£17.49) and the Lumsing 10400mAh Power Bank (£17.99).

For something a bit more special and extra fun, there's the Freeplay TUF, £29.95, which is perfect for the adventurous dad, as is the BioLite CampStove, £139.99, which can charge your phone while you cook your dinner on a camping trip.

BioLite CampStove, £139.99

Father's Day Gift Guide: Speakers

Denon Envaya Mini, £99

Another good accessory option is portable speakers. Our favourite at the moment is the Denon Envaya Mini, which looks and sounds great and is good value at £99.

Inateck BTSP-20, £29,99

A cheaper option is the rugged, splashproof Inateck BTSP-20 speaker, which costs £29.99.

More speaker options can be found in our 19 best portable speakers round-up.

Father's Day Gift Guide: Headphones

Denon AH-D600, £350

Alternatively, if you'd rather your dad didn't broadcast his terrible music taste, how about a new pair of headphones. We talk you through 29 of the best in our round-up, but we'd recommend the Denon AH-D600 if you've got the budget for a £350 set of incredible headphones, the Bowers & Wilkins P3 if you're after a mid-range pair for £169, or the RHA MA450i in-ear headphones at £39.95.

Creative Sound Blaster Jam Bluetooth headphones, £39

Why not free your father from the tyranny of cables with a pair of Bluetooth headphones. Our favourite affordable wireless set are the Creative Sound Blaster Jam Bluetooth headphones, which are a bargain at £39.

Father's Day Gift Guide: eReaders

Kindle Paperwhite, £99

For the book-lovers out there, Amazon is offering its Kindle e-readers at a discounted price this Father's Day. The Kindle Paperwhite is currently only £99.
