VOLTRX Premium Electric Protein Shaker Bottle, Made with Tritan - BPA Free - 24 oz Vortex Portable Mixer Cup/USB Rechargeable Shaker Cups for Protein Shakes

This mixer gets my protein shakes fully mixed with no clumps every time. It's super easy to clean and way more effective than the typical shaker cup. Battery life is also great and can go a LONG time without needing to recharge. To get the best results, I recommend putting whatever liquid your using in first, turn it on, then add your powder while it's spinning. This keeps the powder from clumping or getting stuck to the bottom or top of the mixer. You don't even need the lid to be on. Depending on how thick your shake is, you might get a small splash when the mixer turns off, so just watch out to avoid getting it on your clothes or something else that doesn't wipe off easily.

After leaving my original 3 star review due to the battery dying, I was able to find the customer support contact information on the Voltrx website. Judith was very responsive and let me know that all bottles come with a 12 month warranty. I just had to send a quick video of the battery not working and she shipped me a new bottle and battery within 24 hours. Her customer service was excellent and knowing that they are so willing to help their customers made me redo my review. Great customer service.It was great while it worked. I’ve had it for 3 months and used it basically every day. Today it randomly decided to quit working. It’s fully charged and everything but won’t turn on anymore. The base never got wet so I have no idea why it randomly quit working but it was nice while it lasted. Won’t be buying another since it quit working so quickly.

I purchased this protein powder mixer in January 2025 to take on a cruise as I have a specific diet with low saturated fats. I mix custom vegan protein shakes every morning to get started. I bought this mixer because I liked the USB-C charging capability and lightweight factor to carry in my backpack. I have to tell you this mixer did not disappoint. I used it every day on the cruise to make my drinks in the morning and it washes out very easy. You just rinse it out air dry no problem. I liked it so much that when I got back, I stopped using my Ninja blender to make my protein shakes because I liked this mixer better. I liked it because of the simplicity and the ease to clean not to mention how portable and compact it is. It’s never failed once and the charging unit holds a charge for a long time. I only charge it maybe once a week. I am absolutely thrilled with this product and I have read that the customer service support is outstanding however I’ve never had to use it yet. If this ever breaks down, I am definitely buying another one. In fact, I might buy a couple more just to keep in case they somehow go out of stock. This is one of my most prized devices that I use every day outside my iPhone you can’t go wrong with this product five stars.

I bought two of these electric shakers due to positive experiences in the past. But I can’t say the same with these.They look great, charge fast, mixes extremely well, and WOULD be extremely handy. If not for their biggest flaw:The cups leak from where the cup meets the lid.No matter how tight I cinch it down, it leaks. Protein. Pre workout. Creatine. Doesn’t matter. Leakage from the top. Having to hold and finish a sticky, leaky drink is NOT worth the “convenience” of this particular electric shaker.Purchase at your own risk.*ADDITIONAL INFO*I figured out the issue I had with both cups. Neither had the rubber ring inside the lid that seals it and prevents leaking. The company reached out to me, and offered to send replacement cups.I will edit my review once I receive them and can better gauge their effectiveness. They are well made cups.SECOND UPDATE:The seller replaced both of the cups I had purchased previously, with the proper o ring in place. And they work fantastic.Mix well, no clumps or grit. Many uses off a single charge. Look sleek.Definitely recommend if you’re tired of shaking that blender ball and tasting lumps.

So I had this gadget sitting in my Amazon cart for about three or four months and didn't get around to buying it. Just purchased it yesterday, and I want to say that this electronic shaker cup works like a charm. I put in two scoops of my favorite protein powder with water and it mixed the solution immediately and homogeneously. It's strong discreet (almost no sound) and low profile and I like the fact that there is no Metal Blade that can be dangerous but a plastic spinner that works as powerful as a metal blade. The Cup itself detaches from the motor for the spinner which is a big plus when cleaning it and taking care of it. I recommend this to anyone serious about their smoothies and protein shakes. I have yet to see how long of a charge it will keep but supposedly you can use it on and on for quite a while before having to charge it again.

Did you know it comes with a 12-month warranty? And their customer service is genuinely top-notch! For the price and the level of support, this easily beats any blender or shaker ball.I’ve been loving it—it’s become a part of my daily routine. Unfortunately, the bottle developed a chip at the bottom and wasn’t locking onto the motor properly. Thankfully, their customer service was incredibly responsive and they're already sending me a replacement.While I’m a bit disappointed in the product’s durability, its everyday usefulness more than makes up for it. At this price, even if I had to replace it once a year, it would still be worth it.

I had the original size before buying this premium version. I like the wider bottoms better. This is too heavy which leads to easier spill. It has a battery that doesn’t last as long and the power is not as I would have expected. Super disappointed and will return it and get another of the wide bottom version. I think the narrow bottom impedes mixing compared with the wide version.
