Autsel Protein Shaker 750ml Stainless Steel with MixBall – Leak‑Proof, Insulated and BPA Free (Blue Green)
Product description
What it is and who it’s for
Autsel’s 750ml stainless steel protein shaker is designed for those who want a durable, insulated bottle that can handle daily gym use. It combines a wide mouth for easy filling with a built‑in MixBall to help minimise lumps, and a leak‑proof lid with a silicone seal. The BPA‑free construction and odour‑resistant interior are aimed at reducing lingering flavours, making it a practical option for protein shakes, water and iced coffee throughout the day. If you value a sturdy, metal bottle that can take a beating from regular workouts and rides to the gym or office, this could be a sensible fit.
How it performs in use

On paper, the insulated design slows ice melt, keeping cold drinks cool for longer—a simple benefit that matters when you’re on the go. The 750ml capacity aligns with typical daily protein intake plans, and the internal measurement markings help with accurate mixing and portion control. A wide mouth makes adding powder and ice straightforward and aids quick cleaning, which is welcome after tough training sessions. The built‑in MixBall promises to improve mix quality compared with a plain metal bottle, and the carry handle adds practical portability.
What stands out and where it might fall short


What stands out is the combination of toughness and practical features in a single bottle: metal construction, effective insulation, a leak‑proof lid, and a handy measurement scale. However, there are sensible caveats. While stainless steel resists smells better than some plastics, lingering odours can still occur if not cleaned promptly after use. The colour option described as blue green is appealing, but if you’re chasing the lightest bottle possible or a model with premium seals or extra tech features, this one is more mid‑range on those axes. Also, you’ll need to ensure the MixBall stays clean—omitting it can reduce mix quality.

What to know before you buy
- Capacity and size: 750ml is convenient for many users, but if you require more liquid storage or frequent refills, you might want a larger option.
- Material and care: food‑grade stainless steel is robust, yet metal bottles can sweat in warmer climates, hand washing is usually recommended to protect the seal.
- Insulation: the claimed cooling effect is useful, but real‑world performance depends on starting temperature, ambient heat and how quickly you drink from it.
- Cleaning: a wide mouth helps, but make sure to reach the interior thoroughly to avoid staining or odours.
- Practical features: MixBall aids mixing, a built‑in handle and leak‑proof lid reduce spill risk at the gym or on commutes.
Who it’s for

This shaker suits gym goers, fitness enthusiasts and anyone who wants a solid, non‑plastic bottle for protein shakes or daily hydration. If you prioritise durability, easy cleaning and consistent cold drinks, it covers those needs well. It’s especially relevant for those who train regularly and need a bottle that won’t degrade after a few hard sessions.


Who it isn’t the best option for
If you need ultra‑light gear, or if you’re chasing a bottle with advanced temperature control (like smart lids or compounds beyond insulation), this product may not tick all boxes. If you’re sensitive to odours and can’t tolerate even minor residual smells, you might want to factor in more frequent cleaning or consider alternatives with different interior finishes.

When it makes sense to buy
Purchase makes sense if you want a reliable, insulated stainless steel shaker with a generous 750ml capacity, a practical wide mouth for quick filling and cleaning, and a leak‑proof design for on‑the‑go use. It’s also sensible if you prefer a BPA‑free option and value a built‑in MixBall to improve mix quality.
What to check before buying



- Confirm the colour is the blue‑green shade you expect.
- Ensure the lid seal is intact and secure to minimise leaks during transport.
- Consider your cleaning routine: can you reach the interior easily with your usual cleaning tools?
- Think about your typical drink size and whether 750ml aligns with your usual serving sizes.
Practical use case
Picture a morning gym session: you scoop powder into the wide mouth, add water, drop in the MixBall and shake. Within a minute you have a smooth shake ready for consumption as you head to work. The bottle remains cool for a while, so you can sip gradually without needing a fridge‑side refill.

FAQ
- Is this bottle truly leak‑proof? Yes, it features a secure flip‑top lid and silicone seal designed to minimise leaks when carried in a bag.
- How easy is it to clean? The wide mouth helps with filling and cleaning, but ensure you clean the interior thoroughly to prevent odour build‑up.
- Will it keep drinks cold for hours? It’s designed for cold drinks to stay chilled longer, though actual performance depends on ambient conditions and fill temperature.
Is it worth it?
Final verdict: Worth considering if you want a durable, insulated stainless steel shaker with a sensible capacity and practical features for daily gym use. It may not be the lightest option or the most feature‑packed bottle, but it provides dependable performance for regular protein shakes and hydration needs.
