Best Smart Water Bottle 2021

To select the ideal smart water bottle, you need to know several things.

First of all, you should consider what you’ll be using your smart water bottle for. For example, if you want a water bottle to take with you while jogging, you might need to search for a model that can sync with a Fitbit or type of other exercise tracker.

Furthermore, when you spend lots of time outdoors or in places without a phone charging point, a smart water bottle with a power bank might be the better option. Having the additional power bank offers you an additional power source to charge your other devices.

To find the best smart water bottle, the most important factors to consider are:

The features. The aim is to select a smart water bottle that makes tracking your hydration target easy and guarantees high-quality .

The capability of the bottle to hold ample water and reminding the user. This factor is crucial in helping a user maintain their hydration goals and stay healthy all the time while they enjoy their favorite sport or on a hunt.

Durability is also essential when picking a smart water bottle. Here, I want to identify the pieces that are durable and guarantee high value for money.

Check out our thorough and honest reviews of the top 10 best smart water bottles of 2021.

1. Hydra Tech Bottle  The Fitness Partner

Best Smart Water Bottle of 2021 - The Buyer's Guide-10TechPro

The first item on our list is the Hydra Smart Bottle. The device not only acts as a water container, but as I will demonstrate below, it serves a number of other purposes, such as providing you with entertainment on the go.

Hydra Tech Bottle Design and Features

Lets first take a look at the design. This smart water bottle is made of high quality plastic so it’s light and durable. The “bottle” part is clear so you can easily see how much water is in it. I hate filling up water bottles that are not transparent – I always overfill and spill the water all over the place so this is a huge plus in my book! It also fits standard cup holders, backpack, and water bottle holders on bikes!

Bluetooth Speaker & Speakerphone

The features of this water bottle are elegantly integrated with the design so let’s start at the top. The top of the water bottle can pop off and has extendable legs so you can remove it and use it as a cool speaker to jam out to your favorite tunes. You don’t have to remove the lid to use the speakers, you can play music with the lid attached and the sound quality is fantastic. The speaker also has a auxiliary port and a Mirco-USB port for charging. 

I think that this speaker design is especially great for bikers! Wearing earphones when you ride can be very dangerous so now you can play your favorite music and still be aware of your surroundings when you ride! 

Not only can your new water bottle function as a sound system but you can active the microphone and use it as a speakerphone. 

Hydra Tech Bottle Lights

While we are on the topic of bike safety I also want to mention that Hydra Tech Bottle has LED lights embedded on the bottom. When you fill u your bottle and switch on the lights the entire thing glows and changes colors. Put this water bottle in your bike’s water bottle holder and you will be much more noticeable to others on the road, especially if you are cycling at night!

The light in this smart bottle can also be used as a lantern if you are out hiking/camping or if your power goes out. 

Hydra Smart Bottle Power Bank and Storage

If those features weren’t enough, the Hydra Tech Water Bottle also has a 4,000m Ah power bank. This should be enough to change the average smart phone not once but twice! This bottle features a hidden little storage compartment that you can use to hold your keys, money, or other small valuables. 


  • BPA Free
  • Has App – to control lighting and effects
  • Many color options
  • Hidden Storage
  • Non-spill lid 
  • Low battery indicator
  • Bluetooth speaker
  • Speakerphone capabilities
  • Light features


  • Only holds 20oz of water.
  • It doesn’t remind you to drink water or track your water intake.

Although the bottle does not have the consumption recommendation capability, its other features are pretty impressive. I am especially impressed by the lighting that helps change the mood to your immediate environment to encourage the owner to continue working out.

If you are looking for a great bottle that works fine without the water consumption tracking capabilities, I would recommend the Hydra Tech Bottle.

2. Sportline Hydracoach Intelligent Water Bottle – The Smart Bottle for All

Best Smart Water Bottle of 2021 - The Buyer's Guide-10TechPro

Almost everyone agrees that we should all drink more water and that staying hydrated is an important part of staying active, but who actually keeps track of that? This water bottle can automatically monitor your fluid intake and let you know when you’ve reached the optimal level of hydration.

The HydraCoach is actually pretty simple to explain.  Upon setting it up, you enter your body weight.  It divides that in half and gives you have the amount of water in ounces you should be consuming in a 24 hour period.  I roughly weigh around 150lbs. So I should be drinking 75 ounces of water a day.  Easy right?  There are three modes on the large and easy to read display.  The instruction manual will throw a ton of acronyms at you that you’ll immediately forget but it won’t matter.  These are the three modes:

  • Ounces Goal, Percentage Completed, Average Ounces Per Hour Consumed
  • Ounces Consumed, Current Running Time, Average Ounces Per Hour Consumed
  • Date & Time

There are three buttons on the water bottle: Mode, Setup, and Start/Stop/Reset.  All are very intuitive and easy to figure out.  The only thing that’s weird is that you can’t be on the Date/Time mode to Start, Stop or Reset the program.  The program runs for 24 hours from the time that you begin.  Each time you take a sip, the counter in the “CamelPak” type sipper counts how much you are consuming.  I usually kept the “Percentage Completed” mode running so I could see how close I was getting to my daily hydration goal.Getting to the goal was easy for me.  Everyday I went over 100%, and one day I reached over 160%.  Over drinking water is fine in moderation, but I wouldn’t recommend  drinking over 200%. 

You may think of the HydraCoach as being an annoying pest as you have other things to do with your day than pay attention to hydration needs, but it was like a fun game for me.  I never though of it as a chore and I always wanted to reach my goal.  The HydraCoach disassembles quickly for easy cleaning and should be done at least once a week.  I wouldn’t want to share this bottle with anyone as the nozzle requires you to put your teeth and mouth all over it.  And although the HydraCoach looks sporty, you don’t have to have an active lifestyle to maintain healthy body water stats.  I would recommend this water bottle to all age groups in every demographic in that proper water consumption is a vital part of everyday living.


  • Drink Monitor – Monitors the total amount of water consumed throughout the day.
  • Personal Hydration Goal – Automatically calculates the amount of recommended and consumed daily water.
  • Average Consumption – Displays the average amount of water consumed per hour.
  • Sip Tracker – Displays the amount and percentage of water consumed relative to your Personal Hydration Goal.


  • Easy to setup and use
  • Focused design and interface
  • Instills a progressive attitude in regards to hydration


  • Needs thread markings for easy attachment.
  • Not Stainless Steel.

If you are looking for a simple, yet highly effective smart bottle to help you attain daily hydration goals, I would recommend this bottle.

3. Thermos Hydration Bottle with Connected Smart Lid  The iPhone Smart Bottle

Best Smart Water Bottle of 2021 - The Buyer's Guide-10TechPro

Design and Features

The Thermos is a cylindrical 24-ounce container that comes in one of two translucent colors, black or teal. The lid for either color is white. It measures 10.6 by 3.1 by 3.1 inches (HWD), which is about the size of any standard water bottle. The bottle is made of BPA-free plastic and weighs 7.36 ounces when empty, and 1.87 pounds when full of water. There’s not much else to the design except for a Thermos logo near the bottom of the bottle, and on the side of the lid.

This would be just another plastic bottle if not for the Smart Lid. A latch is used to keep the clear plastic dome on top closed. An adjustable plastic loop hangs off the lid at the opposite end for carrying. Here you’ll also find a micro USB port for charging. The lid’s lithium polymer battery is good for up to 12 days of battery life. And considering there’s a battery in there, the lid is not meant for dishwashers; you’re best off cleaning the exterior with a dry cloth. It’s also worth mentioning that the Thermos is not meant for hot liquids.

The smart part is the tube you drink through, which has sensors that connect with the bottom of the lid. These sensors measure water temperature and how much you drink. The accompanying free app displays this information so you can monitor your drinking habits.

Pairing, App, and Performance

The Thermos only works with devices running iOS 7 or later, so Android users need not apply. To get started, you need to download the Thermos Smart Lid app from the Apple App Store. I connected the Smart Lid to an iPhone 6 in a few seconds without issue and performed a calibration test, in which I had to wipe the smart tube with a cloth.

Once paired, you can set up a new profile or connect the Smart Lid app to your Fitbit account if you have one. To complete your profile, you set up an intake goal by entering your age, gender, height, weight, and the daily average of minutes you’re active, as well as the activity intensity. The app will then suggest a number of ounces to reach as a daily drinking goal, or you can simply choose a goal for yourself. You can adjust these parameters at any time by tapping on the Profile tab.

On the app’s main screen, you’ll see one large circle with three smaller circles beneath it. The large circle shows the water temperature and indicates how much is left. A snowflake icon at the top indicates whether the water is cold or not. The circles below tell you the number of ounces you’ve consumed, the total number of minutes since the bottle’s last refill, and the number of sips you’ve taken. Each of these numbers reset every time you refill the water bottle.

Below the circles is a progress bar that displays how far along you are toward reaching your daily goal. Beneath that bar is each instance you have refilled the bottle. And at the very bottom of the screen you can tap to view your weekly or monthly activity, complete with graphs for each day, week, or month. You can share all of this information to email or social media by tapping a Share icon at the top of the screen. You can also view your current location and weather info in the upper left corner. A Device Settings page, accessible via an icon in the upper right corner, shows you how much battery life the lid has left, and your total number of refills. You can also rename the bottle here.

As mentioned, info from the Smart Lid app will automatically sync to your Fitbit app each time you finish a bottle of water. In testing, the Fitbit app often needed to be restarted for the Smart Lid’s water data to appear. The Fitbit app displays the daily number of ounces you drink.


  • Measures the intake of liquids while providing real-time temperature readings.
  • The Hydration Calculator calculates your suggested hydration goal based on your personal data.
  • Chart and graph daily, weekly, and monthly hydration progress.
  • Up to a 12 day battery life before needing to be re-charged.
  • Requires iOS7+ and works with the following Apple Devices: iPhone (4S and later), iPad (3rd generation and later), iPad mini (all generations), iPod touch (5th generation and later)

The following is a closer look at the main pros and cons of the Thermos Hydration Bottle with Connected Smart Lid to help you decide whether it is indeed the best choice for you.


  • Tracks liquid intake.
  • Nicely designed app.
  • Measures water temperature.
  • Good battery life.


  • Pricey.
  • Sometimes skips sips.
  • No Android support.

The Bottom Line

The Thermos Connected Hydration Bottle with Smart Lid helps you track how much water you drink, but it’s a pricey way to establish good habits.

4. ICEWATER 3-in-1 Smart Water Bottle – With great sound and light up system

Best Smart Water Bottle of 2021 - The Buyer's Guide-10TechPro

This is a unique choice of water bottle that mixes a reminder to stay hydrated with a bit of a light show and a music player.

BlueTooth Speaker
Beyond just being a smart water bottle, the IceWater is designed as a speaker, as well. This makes it a good choice for if you are working out or exercising. You can mix your portable speaker with your water bottle so that it all will work in one place. It is a BlueTooth speaker, so it will very easily connect to your phone.

Other Features
The BlueTooth speaker would be enough, but there is even more to be excited about with the IceWater. It also uses a very unique kind of lighting system so that you will get quite the light show when you are working out. It uses the same light system to remind you of when you need to get yourself another drink of water.

Cost and Value
for all the extra features that come with this bottle, it is actually one of the cheaper options on this list. This water bottle is better designed for someone who likes to take their water bottle to the gym. It will remain on to remind you that you should be drinking water, and then the effective speaker will do a good job of keeping you motivated to keep going.


  • Great price

5. Sguai by Maxtron 13.5 oz Water Bottle – The Best Smart Water Bottle For Its Money

Best Smart Water Bottle of 2021 - The Buyer's Guide-10TechPro

For those out to get a functional and straightforward smart water bottle, we have our eyes on the Sguai by Maxtron. It will need recharging after a few days, but this is the only thing you have to contend with this bottle.

Design Features

Everything about the Sguai is cute and stylish. It is built from vacuum insulated, food-grade and FDA approved stainless steel. It also features double walls.

It has an auto temperature detection, which is one of the reasons why it is a top pick. The bottle will give you accurate indicators of the temperature of your drink so that you will never have to burn your tongue. A red indicator on the LCD HD touchscreen tells you to wait while a yellow light tells you to drink with caution.

A green light indicates your drink is at the correct temperature.

Sguai will provide reminders to take water throughout the day. It is leak and dust-proof and will isolate any odors such that your water remains fresh and safe for drinking.

A nice addition is a rubberized bottom that allows you to set the bottle easily on a flat desk. This also means it will not tip over or produce a clanking sound when placed alongside other metallic bottles.

Setup and Performance

Sguai does not track the amount of water you take. Contrarily, you only need to charge up the bottle, and you will be ready to receive reminders and know the temperature of your drinks.

To charge the bottle, you need to pull out the rubber insulation on the inside of the cap. Luckily, it is a magnetic charging port that makes it easy to attach to the Magtag cool auto smart charging pad.

Stuff to Consider

Sguai is quite basic. Without an app, you cannot tell how you take your water over time. It also has a 13.5-ounce capacity, which means frequent refills before you reach the recommended daily intake.

The following is a summary of the main pros and cons of using the Pyrus Smart Cup:


  • It gives reminders with a loud beep
  • Accurately tells the temperature of drinks
  • It allows the setting of a personal alarm
  • Made of vacuum-insulated stainless steel
  • Comes with a rubberized bottom for traction on surfaces


  • It does not have hand grips so it can slide when your hands are wet
  • It lacks water tracking abilities to give a full picture over time

It is simple and functional, and that’s what most people want in a smart water bottle. The ability to offer accurate reminders is exceptional on the Sguai. The temperature indicator allows you to depend on it when you need it the most.

The Hidrate Spark is a stylish smart water bottle available in five color options ranging from black & white to purple and green. It has a frosted glass finish and a faceted texture that makes the bottle easy to hold without its surface having to be rough. The lid fits tightly and conceals a round drinking spout for easier sips on the go. The most recognizable element of the bottle’s design is its light. You can set this to glow whenever you’re low on fluids, when you’ve reached your daily goal, or to remind you to drink occasionally.

Setting the Hidrate Spark up involves confirming that its sensor stick is attached correctly, ensuring there’s an airtight seal, and syncing it with the Hydrate app. The stick is where the Spark gets its data from – it is outfitted with a humidity sensor and accelerometers. It knows precisely how much you’ve drunk, provided you set the bottle down on a flat surface to rest for ten seconds after each sip. This data is then transferred to the app every time you’re in Bluetooth range.

The Hidrate app is fantastic both design-wise and in terms of functionality. It has a soothing blue background that contrasts with data on daily or weekly water intake in white.

You don’t need to sync to a fitness app for the spark to determine an optimum daily water intake if you enter gender, age, weight, and activity levels manually.

The bottle’s capability to sync with fitness devices has made it stand out from others such as the Thermos Hydration Bottle with Connected Smart Lid that only works with iOS devices.

On the plus side, the battery life on the ozmo Watertight is fantastic. You can use your smart bottle for up to three weeks before needing a recharge.

10. Gululu Smart Water Bottle & Health Tracker – The Best Interactive Choice For A Kid

Best Smart Water Bottle of 2021 - The Buyer's Guide-10TechPro

Kids also need to learn to drink water often. But, if they don’t do it yet, you may want to involve the Gululu interactive water bottle.

Design Features

The first thing you and your child will notice is a cute Tamagotchi virtual pet on the window of the bottle. After the adorable Tamagotchi, you will probably notice the rubberized bottle that allows for easy carrying. When sipping on the water, the pet will growl and awaken the virtual underwater world of the bottle.

It is exciting to see that kids can drink more, just to play and get rewards from their pet. Not to mention that two kids can shake their Gululu bottles next to each other so that the pets can become friends and start playing together.

It is a fun-filled game that adds up to the bottom line, which is your kid drinking more water. The bottle comes with a charging mat that allows it to charge wirelessly. Gululu will last for about three days on a full charge.

You will also like the easy-to-clean spout that is indicative of the simplicity to achieve a hygienic bottle amidst active kids. The bottle is waterproof, so no external liquids can get in if it is dropped in pools and puddles.

Setup and Performance

Gululu has a companion app that allows you to set your kid’s hydration goals. The sensors in the bottle relay information about your child’s fluid intake. This app will work with both iOS and Android devices, so no one is left out.

We particularly like that the app will automatically update when the bottle is charging. Every update brings with it new characters with different skills to keep kids interested. You know how fast pets become boring in the eyes of children, so new pets are a welcome update.

Stuff to Consider

This bottle is pricey when you have more than one kid. It can be upwards of $400 if you have three kids. The noise controls are also not ideal since you will find even the lowest setting, which is the school mode, quite noisy.

  • The interactive virtual pet is fun to play with
  • Easy to track water intake on the app
  • Updates every night on the charging pad

Seeing that it updates on a daily basis, it is going to be exciting day in day out as kids will not get bored of the same pet.

What Should I Look For in the best smart water bottle 2021?

Before you commit to a purchase, think about how you want to use the smart water bottle, and where. Think about the way you lead your life. Are you constantly on the move? Do you enjoy extreme sports? Will you be using your smart water bottle only at home and work? Do you want to take it with you to the gym or on a bicycle ride?

Focus on the way you will be using your new smart water bottle, and you will know which of the following things you should look for.

Batteries: Smart water bottles need batteries to work. Some of the smart bottles utilize external batteries, while others use internal ones. Some batteries can work for only a couple of hours before they need to be recharged, while others can work for days. The features of a water bottle influence battery life. So, if you use the Bluetooth speakers, then the battery won’t last you a long time. On the other hand, if you plan to only use the display to remind you when to drink, then the battery might last you for a week or more.

Durability: Nobody wants to purchase a smart device only to have it break in a couple of days. So, look for a smart water bottle that can withstand a little bit of punishment. On the other hand, if you enjoy extreme sports, hiking, or cycling, then look for a sturdy water bottle. Most of the water bottles are made from glass, but there are some metal models that can withstand plenty of abuse.

Reminder types: Most, if not all smart water bottles have visual reminders. Whenever you need to drink water, the display will let you know by lighting up. Some water bottles combine the lights with an audible sound. So, if you happen to not notice visual reminders, then you might want to try audio reminders. Certain smart water bottles can vibrate, which can also be a decent reminder.

Other liquids: Bear in mind that you can use some smart water bottles as a thermos. Some models allow you to store coffee, tea, and other liquids. Note that you will have to clean those water bottles regularly. Our advice is to rinse your smart water bottles with vinegar. First, make sure that you can use your smart water bottle for liquids other than water.
