Electric Protein Shaker Bottle - USB Rechargeable Mixer Cup for Shakes and Meal Replacements, BPA-Free Tritan, 24oz

I bought this due to a combo of sendentary lifestyle conditions I live in due to, well, I'm not able bodied. Not that you could tell if you saw me walking down the street due to a reaaaaaally high metabolism, either way, I consume a lot, and I mean a lot, of g-fuel and occasionally a lot of meal replacement drinks. Issue is that due to arthritis in my hands that I've had since I was at least 25, certain times of the year, even typing can be a painful task, let alone shaking a shaker bottle a ton of times a day. The product came in a box with minimal padding, not an issue because it's of a sturdy design, and, they packed the "delicate" base in the top of the lid which suspends it, which would serve to easily avoid a bunch of damage that'd usually happen due to things rattling around. Like I said above, the bottle is of solid material, higher quality than most shaker bottles I've paid too much money for, has a handy easy screw lid and could absolutely be taken anywhere you'd want to take a shaker bottle. the base that does the stirring needs to be screwed into the bottom by the user, once screwed in, though, I've not had any leaks to speak of, and given how easy cleaning is, I do not anticpate the need to remove the base for anything at all, so, I don't see one developing from wear and tear either. the bottle is aesthetically pleasing, and easy to use, the mixer definitely does its part too. I haven't tested it with the meal replacement stuff (I have some Huel, so I'll test it with that since Huel is thicker than most protein shakes I've had over the years and update this reveiw if there are any issues). Operation of the mixer is simple. Press the power button and it does the mixing. Mixing doesn't take too long either, and, if you feel things are properly mixed earlier than its cycle ending, then simply tapping the button again stops it. The charging port is USB-C and behind a waterproofing plug of rubber or similar silicone material that's usually used for waterproofing. The operation can be a bit loud, not "OMFG I'm two rooms away and I just pissed off/woke up my spouse and now I'm going to die a horrible death." loud, but, loud enough that it's noticeable, although, that isn't always the case, I think that the noise was coming from me adding the mix before the water and it getting up under the stirrer, but, I could be mistaken. I don't regret the purchase at all. ... this product also has the distinction of being the only product I've bought where the translation for the card on the inside of the box that asks you to register the product made me chuckle for about 5 minutes, partially because the translation was not bad, but you could definitely tell it was a translation, and it said "If you register now you will get: 1. An extension to an 18 month warranty 2. World Class Customer Service. And More..." I mean..., what's this "And More..." with ellipses and what does it elude to? A treasure? Free products? A lifetime of serving the tyrannical Flying Spaghetti Monster? A portal to a hidden world that's just on the other side of my walk in closet? Dear warranty registration request card, I MUST KNOW. Either way, I can't help but chuckle at it just thinking about it... it's... probably the cutest bit of Engrish I've ever read lol. It genuinely made my dark day just a bit brighter. All in all, this product is an easy recommend from me if you can afford it. Its quality is good, it's sturdy, is water/leak proof like it says it is, is easy to clean (warm water and dish soap into the bottle, turn the mixer one, dump it out and rinse) and the graphic design for the box has all the info you need to operate the device. ( I mean, it's literally one button operation. I cannot comprehend how someone would be able to mess that up... but, then again, Facebook and TikTok are both things that exist... so, there's bound to be someone that stupid somewhere). If you can buy it, go for it, it'll save your hands and wrists that extra bit of wear and tear.

I’ve been using the VOLTRX electric shaker bottle for a while now, and honestly it’s been one of the best shaker bottles I’ve owned. The mixing power is great — it blends my protein shakes smoothly without leaving clumps behind, and the battery life lasts much longer than I expected. It’s also very convenient for the gym, work, or being on the go. What really stood out to me, though, was the customer service. I had a small issue and reached out to the manufacturer, and they took great care of me right away. They were professional, responsive, and made the whole process easy. It’s rare to find companies that genuinely stand behind their products like that anymore. Overall, this shaker bottle looks great, works great, and the company behind it is reliable. You can definitely count on them. Highly recommend!

I just got this, and I absolutely love it. I wasn't expecting something to put a big ass grin on my face like when I used this to mix my first drink. It's silly, I know, but oh well! I've had issues with shaker bottles in the past, usually leaking from day one, even if a little. So far, this has been leak proof. The lid closure is also a bit different from what I've used in the past but this is a nice twist on it (literally and figuratively). I like the color of the one I got, I actually forgot I changed it from the orange so it was a good surprise! The size is good, holding a max of 20oz (600ml), it has a line for the max fill for mixing, though I imagine that's with the lid off? Honestly, not really sure. I will say you should probably listen to it, if you go to the max 20oz line instead of the roughly 15oz line, you're probably going to end up with it coming out the top. With the lid on though, didn't have any issue. Now, I do have two minor gripes, very minor and not enough to remove a star for by any means. First, the design of the bottom of the cup has a lip. Which is probably necessary to ensure a good seal, but it also creates an issue when washing by hand. As soon as you put this under a faucet with the bottom tilted toward you, it hits that lip and launches the water right at you. My shirt is still drying as I write this. Still, it is a minor issue and just something I need to be mindful of in the future. Second, the flip top doesn't have any kind of stop when ... scratch that, just looked a little closer. There are a couple little nubs that if you open the flip a little beyond where it initially stops, it will friction stay in place so you don't get the contents still in the cap on your face when it comes back to smack you XD. I'm not sure that was the intent and do worry about it wearing down the material over time, but it works, and maybe I'll just learn to keep it propped with a finger so I don't have to worry about that.

This a really solid blender - which is really what it is. Effectively and quickly blends protein powder, etc., with little or no unblended powder like you get with a typical shaker bottle. The charge also lasts a while and is very easy to recharge. I think I get at least a week+ of daily use before I need to recharge. And cleaning is a breeze. Just fill it hot water and a little soap and let it run under the faucet. It's also a bargain for the price.

I love the bottle a lot. It works for everything i need it to. High-quality and powerful motor mixes everything perfectly no clumps. The lid is great nothing leaks when you put in bag. I got the 27 ounce version I thought the size would’ve been too big, but it is perfect.

## Update ## After a few days of posting my review of this bottle, the customer service contacted me by email and offered a refund or a replacement bottle. Today, 04-08-2026, I got my new bottle. I would like to thank Voltrx customer service for their support and quick response. I will change my review rate now to check and use my new bottle again. => Advice: keep the base of this Voltrx bottle dry and do not put it in the dishwasher or under running water. I ordered this bottle in August 2025, but it stopped working after 4 months. This is what happened exactly as I got this from another reviewer in detail:- A) First, it started turning itself on, then off, then on again during the night when I am asleep! (would not turn off while running) until the battery charge went all the way down B) Then it stopped completely, and then tried to charge it. The green light did come on for about one minute, then turned off C) After 2 or 3 days of acting funny, it will not charge anymore, and there is no light when I plug it in to charge. I tried to contact the seller, but no answer. Do NOT buy it.

**TLDR:** This is a handy little mixer, not a blender. It replaces those old-school blender bottles with the wire ball, and it does it cheaper. It's great for mixing protein powders or drink mixes quickly and easily. The quality isn't the best, and it might not last long, but it's super easy to clean. If you're making a lot of powder drinks, it's worth it. I'd give it four stars because it could be more durable or repairable. --- Amendment This review was initially done before the postscript addition afterwards. It covers the possible repairability aspect of this product. Even so, I decided to keep my original review the same, and simply make this note, and the one at the end. --- **Product Overview:** This product is a small, battery-powered mixer that you've probably seen all over TikTok or AliExpress. It's got a plastic stirring piece, not sharp or made of steel. It's not a blender, just a mixer. It's designed to replace those blender bottles with the wire ball inside. It's cheaper than those too (Depending on the exact bottle you get), so if you're just looking to mix powders, this is a good choice. **How It Works:** The mixer has a fairly weak electric motor at the base of a plastic cup (Plenty strong to mix protein powders!! Just not a blender!). You fill it with water about three-quarters full, turn it on, and let it create a vortex. Then, you add your protein powder or drink mix. It mixes everything quickly and thoroughly in about 10 seconds. It's super convenient for getting powdery drinks blended without the hassle of using a spoon or shaking a bottle for ages. **Quality and Durability:** While it's a handy tool, the quality isn't top-notch. The battery isn't removable, and the motor is likely pretty cheap. I mena, these cost less than the company that just put a wire ball in a plastic bottle, so, this is too be expected. The USB-C charging port is covered with a rubber insert you take out to charge it, but it will wear down over time. The button feels solid enough, but it's clear that there are quality improvements to be had in the base. It’s not the most durable product, but for its price, it does the job. **Ease of Cleaning:** One of the best things about this mixer is how easy it is to clean. Unlike traditional blender bottles that can be a pain to scrub, you can clean this *like* a blender. Just rinse it out, fill it with water, add a bit of dish soap, and let it blend for 30 seconds. It’s quick and hassle-free. The base also comes off, so you don't have to worry about any crud living at the bottom of the cup in hard to reach places. **Overall Thoughts:** This mixer is a solid choice for anyone who frequently makes powder drinks. It's not going to last forever, but it's convenient and easy to use. If a version with a removable or replaceable battery existed, I'd give it five stars. As it stands, it's a four-star product because it could be more durable. If you need something more powerful, like for blending fruits, you'll want a real blender. But for simple mixing tasks, this does the trick. **TLDR:** The Vortex Blender Bottle has a hidden 18650 battery in its base that's surprisingly easy to access and potentially replace, despite the company not selling replacements. This makes it more repairable than expected, earning it a five-star review. --- PostScript review --- **Battery Access and Replacement:** While writing my review for the Vortex Blender Bottle, I discovered something pretty cool about its battery. Initially, I thought the battery wasn't replaceable, but I decided to check out the base of the blender. It turns out, the rubber feet on the bottom are actually removable, and not just sticky ones you can't put back. You can easily take them out and put them back in. Underneath those feet, there are four screws that are super easy to remove. Once I unscrewed them, I found an 18650 battery inside the base. If you're familiar with 18650 batteries, you'll know they're one of the most common rechargeable lithium-ion batteries out there. They're used in a lot of things, including the original Teslas and even some new ones. Most electric vehicles (EVs) use them, at least until new battery tech comes around. So, if you're comfortable with how these batteries work and how to replace them, you could swap it out. Just remember, not all 18650 batteries are interchangeable, so you need to know what you're doing. Even though the company doesn't sell a replacement battery, getting into the cup is so easy that I'd say it's replaceable, at least by someone who knows what they're doing. You could even take it to a repair shop for help. **Final Thoughts:** Finding out that the battery is accessible and potentially replaceable really changes things for me. I thought the battery was the weakest point of the blender, but now that I know it can be replaced, I'm giving the Vortex Blender Bottle a five-star review. It's a great product, especially with this newfound somewhat unofficial repairability.

This shaker bottle works really well and takes the hassle out of mixing protein shakes. The rechargeable mixer blends powders smoothly with very little effort, and I haven't had issues with clumps like I sometimes do with traditional shaker bottles. The battery life has been good, and it's easy to clean after use. I also like that it's portable enough to take to the gym, work, or while traveling. Overall, this is a convenient upgrade from a standard shaker bottle and does a great job mixing shakes quickly and evenly.

I’ve been using this shaker bottle for protein shakes and it’s been excellent. The rechargeable mixing feature works much better than a regular shaker ball, leaving very few clumps even with thicker protein powders. The battery lasts a long time between charges, and USB-C charging is convenient. The bottle feels sturdy, doesn’t leak, and is easy to clean after each use. I also like that it’s quiet and mixes quickly without making a mess. Overall, I’m very happy with this purchase. If you’re looking for a high-quality electric shaker bottle that’s easy to use and does a great job mixing shakes, I’d definitely recommend this one.

I’m very satisfied with my VOLTRX shaker! Compared with the VortexBoost II, this model mixes faster and more smoothly, making protein shakes perfectly every time. The build quality is excellent and it’s very easy to clean. On top of that, the customer support has been amazing — The customer support team was kind, quick to respond, and very helpful. I really appreciate both the product and the service. Highly recommended!

It has been 2 week . Very good and a Best Buy. Could have been more better if it had protein powder box attached

Best sealed blinder i ever had

This shaker is really nice and feels like great quality for the price. I’m very happy with it—it’s a big upgrade from the traditional shakers I used to use. It makes mixing much easier and more convenient. The only downside is that it doesn’t always mix everything perfectly—some small clumps of protein powder or creatine can remain. But overall, I’m very satisfied with this product.
