Best Protein Shaker Bottle Fully Reviewed – Garage Gym Builder

last updated Jun 14, 2019

Protein shaker bottles are a common sight at the gym, and have been years. With their little wire balls and filter lids, they generally do a decent job of mixing up your post workout shake. Still, they don’t give you the type of frothy finish that you get with an electric protein shaker.

Fortunately, there is an innovation that changes that – the battery operated electric protein shaker bottle. Electric protein shaker bottles create a funnel at the bottom of the bottle to deliver a delicious protein drink every time, with that nice milkshake consistency. No furious manual stirring is required.

In this article, we review the 10 best shaker bottles we found in our research. We're talking protein shakes here, but you can blend creatine, supplement powders, or practically any other powder-based fitness drink with these products.

Pros:

1600 RPM motor

USB Port

BPA free

Easy clean

Cons:

Can only blend powder

The InstaSkaker features a powerful 1600 RPM motor. It creates a vortex that will dissolve any lumpiness in your protein powder. You get a frothy drink that's easy to pound down when you need it.

Read more

The protein shaker comes with a USB charger and cable, so you don't have to worry about changing batteries. It comes apart for easy cleaning. Instashaker offers a 12-month warranty in case something goes wrong; the design and materials are durable enough that we don't think anything will.

The food grade material used in the construction of this bottle is BPA free and provides the same level of safety you'd get with a baby bottle. This protein shaker is easy to pull apart for cleaning, and strong enough not to break if you drop. You can also put the blender and blades in the dishwasher.

This protein shaker can be used for both hot and cold drink mixes. The blades are not strong enough to cut fruit or crunch ice, though. You can only use this product for powders and liquid.

Pros:

Stainless steel rod and blade

Free 500 ml sports bottle and lid

Cons:

Can't blend ice

This stout little blending machine features an ergonomic comfort grip handle and a stick blender you can rinse off and use to stir up dinner.

Read more

It is a versatile general purpose blender and fitness drink mixer all in one package. You can mix a protein shake in the detachable bottle body, then take that part with you to the gym. The stick mixer, without the bottle, does double duty in the kitchen. With this blender there are fewer parts to keep track of, as you can leave the actual blender part at home when you head to the gym.

The dial has six-speed settings, but this is a seven-speed blender, which is a bit confusing. The highest setting is turbo mode, which is past six but not marked as seven.

The stick blender is stainless steel, with a 300-watt motor to grind out a shake with the perfect consistency each time.

All of Gourmia's blenders are ETL certified for safety and quality.

The Hamilton Beach portable blender lets you make protein drinks, smoothies, juices, purees, and even baby food with fast one-touch operation. The 14-ounce blend chamber detaches so you can grab it on the way out the door. You can run blade and lid through the dishwasher together. The BPA free unit is light, compact, and ready for your fitness adventures.

If you live in a small space, you could save a lot of counter space with Hamilton Beach. The measured pulse delivers consistent drinks every time, with a shake or smoothie feel according to what you use for ingredients. Open lines on the jar front let you mix powder and liquid to your exact specifications.

Cons:

This compact blender is powered by a 24,000 RPM motor, with a 20 ounce plastic blend chamber that doubles as a water bottle.

Read more

The lid has a safety feature that will not let the four blades start until the lid is snapped firmly in place. It is good to have if you are allowing young kids or teens to share your blender. The blender will shut itself off after two minutes to prevent overheating. We can't imagine why anyone would make it run that long, though, as the chopping and blending would finish long before then.

The locking blades are protected by a lid designed not to leak. The feet are suction cups to keep the personal blender stable and attached at all times. The bottom base is designed to reject heat safely, although there is an interlock to shut off the blender if it overheats.

The dishwasher safe goes bottle is a generous twenty ounces made of BPA free plastic. Cusinaid offers a one year warranty on the product.

Criteria Used for Evaluation

Battery Life

if it's lightweight and portable, but it still needs power, battery life matters.

In doing these reviews, we noticed that the lower end models, the less expensive ones with fewer special features, used AA batteries. These batteries are useful, but they begin losing power the minute you install them. It means replacing the batteries. It isn't hard, and you can typically tell when a protein shaker is running low on battery power, but it still may not be cost-effective to save money now and always have to buy batteries throughout the life of the product.

Most of the protein shaker bottles we looked at, though, had batteries you can charge. Often, these products are described as USB blenders. Charging the blender, if you use it daily, is just as easy as charging your phone or tablet. You may find yourself in a place where there are no charging ports, while away from home, but those places are getting more and rarer these days.

A lot of protein shaker bottles come close to bypassing the battery issue entirely. They are the ones with removable blend chambers. If your drink is already blended when you leave the house, you won't have to worry about batteries. It's good to see manufacturers adapting to customer demand and introducing innovations that then become industry standards.

Durability

A portable blender has to house and protect a lot of moving parts in a small shell.

Manufacturer's warranties are a good rule of thumb for gauging durability. A company offering a 30-day guarantee may not be as confident in its product as one that comes with a year warranty. So when you are shopping for a personal protein shaker bottle, it is a good idea to look at what each product can offer you in terms of confidence as well as price.

Other factors that go into durability include materials and anti-leak measures. A protein shaker bottle that leak is one that nobody wants to use. Silicone gaskets, snap-in lid tops, and quality plastic blend chambers all help prevent leakage. Steel blades are the industry standard, but how long will the blades on a blender stay sharp? And can you sharpen them? If not, can you buy replacement blades, or do you have to buy a new blender? These are smart questions to ask.

Ease of Use

Mini blenders don't get very complicated, but there are still some ease of use consideration.

We've mentioned water bottle blend chambers before, but we are coming back because they can be substantial.

Most of us want a portable or single protein shaker, in the first place, for speed and convenience. We may have an older style glass pitcher sized protein shaker around somewhere, but we don't want to lug that out every time we need a fitness drink. The single serving protein shaker means you can always make an exact amount, and the water bottle models expect you can take part of it with you. With a larger blender, you would be washing both it and your drink cup out later.

On/off switches are essential, too. Some of them have to be held down through the whole blend cycle, while others you can press and trust the auto stop. You may find standing and holding the button inefficient or just tedious. Since this is your investment, designed to suit your life, the type of switch could be a deciding factor.

Effectiveness

Effectiveness is not always objective or easy to measure.

Effectiveness, past the primary chopping function of any blender, becomes a matter of personal taste and individual needs.

If you are interested mainly in smoothies and shakes, you will need a protein shaker that can handle ice, veggies, frozen fruit, or perhaps even nuts and seeds. Anything less would be ineffective.

If your sole purpose is to mix sports powders into pre or post workout drinks, you may be interested in a water mixer. These do not have any blades to go wrong or need replacing. A simple blender, just a step or two up from a protein shaker bottle, will be all you need.

Besides the personal factors, every protein shaker needs a good motor, the ability to charge quickly and hold a charge, and a consistent outcome, with smooth drinks as desired.

Weight

Nearly all these blenders are designed for when you're on the go.

There are not any heavy portable blenders.

We still considered weight, though, because we didn't want our readers getting caught up in an abundance of features, not realizing that all those features could add weight or bulk and make the protein shaker harder to carry.

If you only ever plan on using the protein shaker at home, the weight will not be necessary. Typically, if you are going that route, you will opt for one with a water bottle blend chamber. Today's plastics aren't lighter than air, but the cup won't weigh much more than what you drink from it.

Blenders Versus Food Processors

If you have done much home appliance shopping, you may have noticed there were both food processors and blenders in the same shelf area. While these two appliances serve similar needs, they are not the same.

Blenders are usually only powerful enough to mix liquids and powders. Their effect is similar to stirring a drink with a spoon, but faster and more powerful so the ingredients won't separate and none of the powder will settle.

Food processors are tough and hardy.
They are the workhorses of kitchen cooking. With its bigger motor and different blade design, a food processor can cut through seeds, nuts, veggies, ice chunks, and even dough as if it were never there. It is what you would need to use a puree.

When it comes to actual cooking and meal prep, you will probably need a food processor. You can use a blender to make smoothies, juices, and sometimes dressings.

In recent years, though, portable blenders have given the mighty food processor a run for its money. A unit half as big as an older food processor--or even smaller--might be able to chop semisolids as well as any processor. The disadvantage with a blender like this is that you would have a hard time making a meal with it.

Don't Give Up On Protein Shaker Bottles

We all know that a portable protein shaker can give you a finer consistency drink, in less time, than a bottle with a shaker ball would. Many times, you may have made your protein potion, only to finish your workout and find that half the powder was stuck to the bottom of the bottle.

But protein shaker bottles are not ready to go extinct just yet.

Protein shaker bottles are less expensive than portable blenders. For someone just getting into weightlifting, who isn't planning on making any complicate smoothies, this may be just the thing. You can't break the ice in a shaker bottle, but you can use it to keep your drink cold. Down the road, a beginner can decide if they need a portable blender or not.

Protein shaker bottles have fewer parts to break down, overheat or need replacing. They are easier to clean, usually just having a cup, sip lid, and metal ball. Batteries never need changing. You don't have to worry about losing your cup and ending up with just the base--if you lose the shaker cup, you lose the whole thing! And, of course, the protein shaker bottle will be cheaper to replace.

Other Factors to Consider

Use

Each entry on our top ten list only needed to do one thing well: mix protein or other workout powders into the liquid of the user's choice. Everything else was just gravy.

But everybody likes gravy, so we also considered whether the unit could handle ice, veggies, frozen fruit, seeds, or nuts. Many of them can. If you can get one of these heavier duty units, for close to the same price as a powder only one, it may be worth it to have all those other options.

Capacity

None of the detachable bottles we looked at could hold more than 20 ounces. If they got much bigger, they wouldn't be portable anymore.

Some held as little as 12 ounces.

We considered capacity but did not give any units low ratings for having lower capacities. Everyone's needs are different. The bigger a bottle gets, the harder it is to keep in your cup holder. You may need something you can carry in your hand for walking or running, and a large capacity bottle is too cumbersome. We have tried to provide enough information for you to decide how much liquid is right for you and how much isn't.

Frequently Asked Questions

q: Are speed settings important on a portable protein shaker?

a:

It depends on what you are blending, but, typically our answer is no. If you were buying something bigger, for kitchen use, speed and consistency settings would be vital if you wanted to follow recipes. But for something you will use to make a recovery drink or even a smoothie, you need something that will be more efficient than stirring or shaking.

q: Can I use a portable protein shaker bottle for hot drinks?

a:

We do not recommend using any small protein shaker bottle for hot liquids unless the manufacturer specifically says you can. Too much heat can cause the inner components to wear down more quickly. Coffee, especially, can stain the inside of the blend chamber and affect the flavor of drinks. And unless your protein shaker bottle has a locking lid, there is a burn danger if hot liquid sprays out of the top. Also, the gaskets used in protein shaker lids are not always rated for hot liquids. Even if they don't spray, the heat can cause leaks that will get worse over time.

q: How does a vortex mixer work, if there are no blades?

a:

First of all, it is essential to remember that vortex mixers are only active for blending liquids. The water shooting through the chamber will dissolve your powder with its pressure, but no consumer vortex mixer can crush something like a pea.

The vortex mixer or protein shaker bottle has a motor in the base that transmits its rotating energy into a vortex or whirlpool inside the chamber. There are usually small blades, like on a windmill, that is responsible for agitating the water and creating the pressure that will blend your ingredients.

The water pressure is also enough to blend liquid soap, making many vortex mixers self-cleaning.

q: Can't I crush smaller ice cubes in a protein shaker bottle that says it can't do ice?

a:

You can, but this is likely to burn out the motor, dull or break the blades, and void the warranty. If you want a small unit that can handle ice but don't plan on making elaborate smoothies or juices, you may wish to buy one that has its ice cube tray. The ice you make in this tray will be the maximum safe size for your protein shaker bottle.

q: I see that nearly all these protein shaker bottles with plastic parts are rated BPA free. What are BPAs again?

a:

BPA, or bisphenol A, is a chemical additive that naturally makes plastics stronger when added in the manufacturing process.

BPAs were standard in plastic products of all kinds for decades. Since the early 2000s, scientists and health care professionals became concerned because BPA does not entirely bond with plastic when it is added. Some of the BPA stays in the product's contents, where it can leach into food, drink, or even your skin. Some of protein shaker bottles on our list are BPA free.

Studies have indicated, though not conclusively shown, that BPA can cause infertility, certain forms of cancer, heart disease, Type 2 diabetes, and other serious health effects.

For this reason, many consumers and manufacturers steer clear of BPA.
Safe exposure levels are still unclear. Canada, China, the EU, and a few other countries have already banned the additives.
