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

Great product with a variety of beautiful colors! Ive bought a few of these now and I continue to be impressed. When I had a issue with one of them, I reached out to customer support and they immediately helped me. They were extremely kind, fast, and understanding, which reassured me and further strengthened my loyalty to both the product and the brand.The blender itself works well and blends smoothly without clumps and is perfect for protein shakes, pre-workout mixes, smoothies, and superfood blends. Its portable and convenient so i dont need to drag around a large traditional blender since the bottle itself is the blender which saves time and reduces the amount of time and stress we all know can come with cleanup especially if you have a busy schedule. I haven't had any leakage issues so id say the seal is nice and tight and the build quality feels sturdy. The battery's rechargeable and lasts a good but not great amount of time between charges but honestly a minor issue as you could just pop onto one while youre doing literally anything since it doesn't take long plus its a nice compact size so you could easily throw it in a gym bag, take to the office, or even go traveling with it which I tend to do.This is a must-have for gym rats, busy professionals, or honestly just anyone who wants a reliable portable blender thats still stylish and easier to clean especially with all the pieces and nooks and crannies you have to go through cleaning in tradition blenders.

I have owned this product for 3 years and it’s been great. It’s perfect for mixing protein shakes, green drinks etc. It’s also been very reliable as I have been using out for 3 years and it’s been rock solid. It’s simple to use and to this day I do not have any leaks. It can hold about 24 oz and it has not issue mixing whatever drink you have. After so many years of washing it, it’s still its original color. (Mine was black). I couldn’t recommend this product enough.

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.

This is the second VOLTRX bottle I've owned and I've loved them both. Their quite sturdy, mostly easy to clean, and mix the shakes that I use these bottles for well. The only reason I'm giving this 4 stars instead of 5 is because of how it operates. One press operates the mix for 30 seconds, 2 presses operates it for 3 minutes. However, the wimdow to perform the double press is weird. Can't press it too fast, or too soon, or too late, or too slow. Most the time I end up only activating the 30 second mode at least 3 times before I can successfully activate the 3 minute mode. This happens to me on both the units I use.

Thanks to Voltrx's costumer service, more specifically, Judith for sending me a replacement shaker after my base stopped working. Judith offered me a new shaker with a color of my choice even though it was my fault the shaker stopped working. Overall, the product is fantastic, mixing peanut butter perfectly with your drink.

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.UPDATE: 9/10/2025Still going strong. Use it everyday it’s never failed. It travels around with me. I just bought another one in white cause it’s easier to see through. I will be giving these as gifts at Christmas time. Love this blender.
