HYDRATE Electric Protein Shaker Bottle, 15.2 oz - USB Rechargeable - Gym Shaker Bottle - Food Safe with Measurements - 800mAh Battery, 5000-6000 RPM Motor Speed - Portable Blender for Protain - Gray

Updated - A few months later and the battery does not seem to charge, the bottle is basically useless at this point. To bad it was a good product while it lasted.Cool product works well as described. The electric function mixes the drink well. It does leak a little bit so maybe that can be improved on a future model. I like that it has USB C charging. It's relatively easy to clean, put some warm water in it and hit the stir button.

The media could not be loaded. As someone who regularly uses protein shaker bottles, I recently tried out the Protein Shaker Bottle, 15.2 oz - USB Rechargeable. While it has some positive aspects, there are also areas where it could be improved.**Material Quality:** The bottle itself is made of decent quality plastic, but I found the bottle cap to be a bit cheaply made. It doesn't provide a tight seal, and the spout can be easily pushed open, which is a concern for potential leaks.**Motorized Mixing:** The shaker bottle features a motorized base for mixing protein shakes, which is a convenient feature. However, it's important to note that this is not a blender, so it's best suited for mixing protein powders rather than thicker ingredients like raw fruits.**Performance:** While the motorized mixing function does the job, I found that it didn't fully dissolve the protein powder as effectively as other similar bottles I've used. There were still some clumps left behind, despite following the instructions.**USB Rechargeable:** One of the standout features of this shaker bottle is its USB rechargeable design. It's convenient to be able to charge it up and use it without the need for batteries, providing added versatility. The light on the unit also glows and shows how much charge the bottle has when plugged into the USB-C port.**Overall Assessment:** The Protein Shaker Bottle, offers some convenience with its motorized mixing function and USB rechargeable design. However, it falls short in terms of leak-proofing and fully dissolving protein powder. It's a decent option for those looking to upgrade from traditional manual shaker bottles, but there is room for improvement in its design and performance.

It's like the Franco Columbu of protein shakers, small but powerful. Kind of reminds me of the blender bottle but better. Love that it's rechargeable so I don't have to change batteries, but to be honest, it's 2024 so the ability to recharge is expected. The perimeter has a hexagonal type shape which makes it unique but also adds more grip. The bottle seems pretty small compared to a blender bottle but I find it to be the perfect size for a serving of whey protein. It has rubber gaskets on the lid as well as the spout. It doesn't have a strong lock like the blender bottle but definitely enough to keep it from popping open randomly. To be honest, I found the blender bottle spout cap to make too much noise when opening and closing so I quite like this change. Looks and feels really cool and modern. There are some lights at the bottom that create a spinning cascade effect when it is blending which makes it really fun to use although it kills the battery faster. Each mixing cycle lasts exactly 30 seconds before shutting off automatically and I was able to get 7 cycles on a full charge. It takes 1 cycle to fully dissolve my pre-workout and 2 cycles for my whey protein.Pro tip: To avoid clumps, add half your liquids, then add your protein powder, then mix, and then add the rest of your liquids before mixing again.Note: It can start leaking if used as a manual shaker. My cup started leaking when I shook it manually because it was out of battery. Once I powered it up with the motor, the leaking stopped. I'm guessing the gaskets realigned themselves from the spinning.

Maybe I got a dud, but this blender/shaker bottle sucks. I fully charged the battery this morning before using and it died within 90 seconds. For those 90 seconds it worked fine, had a strong vortex to mix my protein shake but just couldn't finish the job. I had to recharge to finish mixing. If I'd taken this to the gym without the charging cable I would've been out of luck. The base of the cup (where the "blade" is screwed in) has a leak rendering it useless. I wouldn't recommend this blender/shaker bottle.

Has to be plugged in now to use

EDIT - I think I may have judged this too harshly at first. I've been using it every day since I got it, so I must like it more than I initially thought. So my initial three star review is now a four star. Again, if I could do half stars then it would probably be more like a 3.5 but given that I'm using it regularly I feel I have to go with the higher rating.********************************This electric shaker cup functions well, but its small size and lightweight materials are a minus for me. Even though it says it is a 15.2 oz cup, I'm not sure I'd fill it that full since once you start the mixer the liquid volume temporarily expands, meaning if you fill it too full I assume you'd run the risk of it overflowing.If I could give it 3.5 stars I would; in many cases in this situation I'd give it the benefit of the doubt and go with 4 stars, but in this case I just can't; I don't love the product enough to give it that fourth star. It's not a "bad" product, but not particularly great, either.This review is for HYDRATE Electric Protein Shaker Bottle, 15.2 oz - USB Rechargeable - Gym Shaker Bottle - Food Safe with Measurements - 800mAh Battery, 5000-6000 RPM Motor Speed - Portable Blender for Protain - Gray
