Protein Shaker Bottle, Merger USB C Rechargeable Electric Protein Shake Mixer, Shaker Cups for Protein Shakes and Meal Replacement Shakes, BPA Free, 24oz

Update: Just a few days later and I received a brand new shaker bottle to replace my old one. Very impressed with the customer service. Updated the star rating to 5 since I love the shaker bottle. I bought this in Nov. 2024. I have used it nearly every day since then to make my morning supplement drink. I love how I just push the button and it mixes all the liquids and powders together and doesn't make a mess. The bottom base detaches so it can be cleaned by hand and the rest can go in the dishwasher. I normally would just have to charge it once a week. It was working fine until about a couple weeks ago. The battery wasn't holding a charge very long and I had to start charging it in the middle of the week. And now this week, I have had to charge it every day. This morning, it wouldn't turn on at all, even after having charged it yesterday. So - gasp - I had to shake up my drink by myself! Not the end of the world, but when I bought this bottle to do it for me automatically, well, it is no longer as useful. Before the battery malfunction, this bottle was great. No leaks, very portable, and decent quality. I guess that's why I'm less than thrilled right now. I did send a message to VOLTRX about my issue, so now I'll wait to see how they handle it. I will update if I hear back, and possibly update the star rating, depending on how they respond.

There isn't much to say except to buy it. It’s mixed and blends shakes well. I even add a little blue spirulina to my shakes too and for the money it is worth every penny! I can’t stress enough how awesome this shaker is. It is leak proof, the size is perfect and labeled for ounces for those counting calories and such. It’s very easy to clean and it’s pretty durable. I’ve had zero issue and I’ve only had to charge it once since I’ve had it. It is also USB-C for fast charging.

Very strong motor, easy to clean. I use it 2x a day, and have gone 3 days without charging in between and it has not died. Mixes extremely well (no chunks). I use about 10oz of milk + one scoop of protein, and itl be fully mixed within 10-15 seconds. Cup seals well at the bottom, haven’t had a leak. I overall have no complaints, I’d recommend this bottle to anybody, and I’d buy it again 100%. One of the rare occasions where I’m fully satisfied with my Amazon purchase.

This VOLTRX shaker is amazing! It mixes protein powder and supplements super smoothly with no clumps at all. The motor is strong, the battery lasts a long time, and it’s easy to clean after use. I really like the design and the light at the bottom. Way better than regular shaker bottles

I honestly didn’t expect to like this cup this much — but it completely won me over. I use it daily with Naked Whey Isolate, which is usually harder to mix, and the result surprised me: perfectly blended, creamy texture, zero clumps — something not every electric shaker can do. What impressed me the most: ✔️ It actually blends – not just shaking and hoping for the best. ✔️ Fully automatic – press the button, it does the job and stops on its own when finished. ✔️ Creamy consistency – the whey comes out smooth, never watery. ✔️ Perfect for daily use – fast, quiet, and easy to clean. ✔️ Ideal for clean proteins – works extremely well with purer whey isolates like Naked Iso. I use it for coffee with whey, whey with water, and even on days when I’m in a rush — and the result is always consistent. 👉 Highly recommended, especially if you use whey isolate or cleaner protein powders that don’t mix well in regular shakers. One of those purchases that genuinely improves your daily routine.

This Voltrx cup works really good mixing my shakes without leaving grit or clumps. I put a little less than half the liquid then add the powder and mix a couple time's. Its really easy to clean. Worth the money to me.

I've had this bottle for a few drinks now and I can already too you this bottle is amazing! It works better than I thought it originally would. With a normal blender bottle, even after shaking for 30-45 seconds, id still have clumps/chunks of unmixed powder. I was expecting this bottle to be the same with my drinks having some clumps in it, but just less effort for me in mixing, but this thing leaves little to no unmixed powders at all. I'm also very pleased with how the quality for the price I paid for this. It came in very professional packaging and feels more expensive than what it's worth.

This works very well. Strong blender mixes powder very well. Leaves no lumps from protein and does it in 2o seconds. Great for mid workout mixer!!!!

Sono molto soddisfatta dell'acquisto. Lo shaker si presenta bene, è di qualità e funziona perfettamente. È molto pratico da caricare: la base si stacca per la ricarica e si ricompone facilmente per l'uso. Attenzione: lo shaker è pensato per miscelare proteine in polvere e non per fare frullati di frutta o verdura. Non ha lame all'interno, ma una "farfallina" che mescola e monta i liquidi. Ne sono così entusiasta che ne ho acquistato un secondo per mio figlio!

Excelente, atendeu todas as minhas expectativas
