The wire blending ball is standard but gets the job done, earning a 4 out of 5 for effectiveness. After 30 seconds of shaking, the liquid and protein powder were well-combined. But the bottle and ball were quite noisy during mixing—a fine trade-off for the bottle's high-quality durability, according to our tester. Our tester also liked the bottle’s design, with vertical bars and a carry handle that make it easy to grip. It fits in a standard cup holder for on-the-go usage and has volume markings up to 24 ounces. For some, the timing involved with a manual shaker bottle is a deterrent to using it. That’s where this blender bottle comes into play. It’s a single-serve bottle with aluminum blades that makes the perfect protein shake without you having to break out a timer. Our tester said, “I would give this to anyone who wants an easy way to blend and get right to exercising.” Most blenders are cumbersome, but this one is small enough that you can take it on the go. If you’ve ever used a shaker bottle, you know that cleaning the shaker ball can be a pain, particularly the spiral wire ones. This shaker bottle’s helix design means you can have a well-mixed protein shake without a shaker ball. The Contigo Shake & Go shaker bottle has a convenient carry loop, a leak-proof design, and a large capacity. It fits into a standard car cup holder, so it’s perfect for when you’re rushing to a gym session or taking your breakfast on the go.

VOLTRX’s Premium Electric Protein Shaker Bottle uses BPA-free plastic blades and a strong motor to perfectly blend your pre- or post-workout drink. After two minutes of hands-free blending, our tester enjoyed a smooth and clump-free protein shake. First things first, consider what size shaker you want. The capacity you need in a bottle depends on how much pre- or post-workout liquid protein, electrolyte drink, or smoothie you generally require for your fitness goals or nutritional needs. Whether you are a marathon runner or focus on strength training exercises such as using a balance board, the amount of beverage you need is a personal decision. This bottle does not have a shaker ball. Instead, it has agitator lids to mix your shakes, which our tester felt worked very well. If you’re an avid gym-goer who likes having a pre- and post-workout shake, this could be a great space-saving product.

We were impressed by this bottle’s unique design. It’s divided into two sides: a 14-ounce section for your pre-workout drink and a 22-ounce section for your post-workout drink. Each section has a separate mouth spout, and the bottle does an overall nice job of preventing the two liquids from mixing. Our tester said, “Very thorough and effective product! A lot of thought was put behind the compartment system and how to effectively mix powders in each compartment independently.” Many shaker bottles are made of BPA-free plastic, which is valuable because BPA has been linked to a variety of health concerns, including cancer and polycystic ovarian syndrome (PCOS). Their capacity varies, with most ranging from 16 to 28 ounces. We tested multiple shaker bottle options on the market, considering their design, mixing effectiveness, and ease of cleaning. I would highly recommend this product to everyone. Just the fact that it can mix well without a ball is game-changing,” our tester said. “Cleaning that ball can be a pain, and sometimes I can't even find it when I need it.” It’s one less thing to worry about, and our tester found it still made a well-mixed shake with no caked-on powder residue. Whether or not a shaker bottle is worth it will depend on your habits and preferences. If you regularly consume protein shakes, then a shaker bottle is worth it because it will lead to a tastier drink, and you’ll get good use out of it. If you only have a protein shake every once in a while, then you might not want to invest in a high-end bottle, but a simple, low-priced option might serve you well. Ultimately, shaker bottles can make protein shakes smoother and tastier, so if that’s something you’re looking for, a shaker bottle will be worth it. Your bottle’s internal mixing system should be effective enough to blend any powder into your liquid base. Options ranging from metal or plastic whisk-like balls to solid silicone or plastic mechanisms will all efficiently break up clumps. And bottles with screens, like Matrix’s Insulated Shaker Bottle, agitate ingredients just as well while shaking.

Ferriter favors wire spheres for her shakers. “They can mix all the way through your drink. That said, the screw top agitator lids have their purpose, too," she says. While stainless steel balls are typically an odor-free and easy-to-clean part, BPA-free plastic and silicone components tend to be less noisy, so this mostly comes down to personal preference. To clean it, simply add soap and water to the blender and turn it on. It will self-clean, so you don’t have to scrub the sharp blades with a sponge. Our testers used the bottles to make a protein shake and cleaned them afterward. They paid specific attention to the bottles’ design, effectiveness for mixing, and ease of cleaning. Testing Notes: “I would recommend this to anyone who needs a pre- and post-workout beverage but wants to consolidate both beverages into one bottle.”

Whether you're looking to gain muscle mass or need added protein in your diet, there are a lot of different uses for protein powder, says Allison Knott, MS, RDN, CSSD, a board-certified specialist in sports nutrition who guided our testers on test day. A quality electric shaker bottle might come with a slightly higher price tag than traditional plastic versions, but the smoothness and consistency of the shakes justify the cost. Ensuring a well-mixed protein shake is vital, and these USB-powered bottles excel at that. They’re convenient for on-the-go use, fitting snugly into car cup holders, and you can charge them via a USB slot in your car or a power bank. Because of the unique dual-compartment system, the bottle was somewhat difficult to clean. The smaller, 12-ounce side requires a long scrub brush, as our tester noted, after a failed attempt to reach in with his hand to manually clean this side of the bottle.
