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

This protein shaker is a game changer. It mixes everything perfectly without clumps, and I don’t have to shake anything myself. The quality is great. The water flow when it mixes is awesome. Just press the button and let it do the work. The design looks really cool and it's sturdy. I haven't had any issues with the lock feature. It seals perfectly well. Easy to clean and there isn't a smell after it's clean. It’s USB rechargeable, easy to clean, and the battery lasts a long time. Great for post-workout shakes or meal replacements on the go.

**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.--- AmendmentThis 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.

The cup mixes my protein shakes very well. Easy to clean, easy to open. The mixer does have a slow to moderate mixing speed. A single charge has lasted over 3 weeks with mixing at least twice per day. The biggest flaw I've found is that the bottom seal between the cup and the charging bottom leaked. Half of my cup was gone before I realized it. Even after hand tightening the bottom as much as possible, it still leaked. I dried the cup off to see where the leak was coming from just to be sure. The value is on point, but the design has a flaw, or maybe I got a bad one.The seller was very quick to rectify the situation and exchanged my blender for a new one. Exceptional response time and great communication from the seller. My new cup has not leaked. Cheers!

"This is definitely one of the best bottle mixers I’ve ever used. It works great, the battery life is long-lasting, and it helps me make all my smoothies with ease. I even use it to mix hot tea — though it’s not really recommended for hot liquids, I let it cool down after mixing and enjoy it that way. The performance and convenience are top-notch. Highly recommend!"
