When it comes to convenience and portability, the PopBabies blender definitely has an edge over the KOIOS 800W. Its compact size and rechargeable battery make it easy to take on the go and use without the need for an electrical outlet. However, in terms of performance, the KOIOS 800W outshines it in every area, with a more powerful motor and thoughtful design.  

In our test, the KOIOS 800W performed really well in blending frozen fruit smoothies and protein shakes, producing some of the smoothest textures we've tasted. Its ability to extract nutrients from leafy greens was average, but still far better than the PopBabies. In addition, it even comes with a generous accessory package that allows for the grinding of dry ingredients. 

Without a doubt, the KOIOS 800W is the superior choice over the PopBabies. However, as these two blenders have fundamentally different designs, your final decision boils down to what you value the most: the unrivaled convenience and flexibility of a cordless blender, or the robust power and versatility that a corded model provides.

  • Blending Time: 3 mins 20 seconds
  • Result: Very Coarse

The testing of the PopBabies blender resulted in a disappointing outcome. Despite the blending session lasting for three minutes and twenty seconds, the oatmeal and almonds were blended well but the almonds remained largely intact, resulting in a chunky and texturally inconsistent shake.

One potential reason for this subpar testing performance is the blender's 175-watt motor, which appears to lack sufficient power to churn through such a tough ingredient. An inadequate blade design and jar shape can be factors that hinder the blender's efficiency as well. 

However, it is important to note that the PopBabies blender had a notable advantage compared to other blenders. During the test, it did not become clogged with food, allowing the blades to turn smoothly and continuously, with minimal disruptions, except for the required idle blending time. Considering this, the PopBabies seems to be not a bad choice for those seeking a quick and convenient solution to make fruity work-out treats. To ensure the best possible results, just make sure to use only soft ingredients.

  • Blending Time: 56 seconds
  • Result: Smooth

The KOIOS’s blade has a rotation speed that is fairly quick for the class so it shouldn’t be surprising that this blender can make a good breakfast or post-workout milkshake in a matter of seconds. Not to mention its high-powered motor and more-than-average number of blade prongs (more prongs means more food contact, and results in faster results).

In this test, it took less than 1 minute to break down and combine all the ingredients, which was faster than most. The powerful motor couldn’t quite remove all lumps from the protein shake, but only a few chunks remained unblended, so our drink was still pleasant to drink. Moreover, the residual solids didn’t affect the tasting experience much — they were so tiny that they didn’t bother us at all. If you want smoother results, consider the NutriBullet or the Ninja Fit, though.

  • Blending Time: 2 mins
  • Result: Smooth
  • Suction:

The smoothie-making capability of the PopBabies was put to the test using four varieties of berries. Eventually, we found that this blender could achieve a smooth mixture within the allotted time of 2 minutes. That said, the final product did not meet our desired outcome of a thick, icy consistency due to the dilution caused by the fast-thawing nature of frozen fruits. Some other blenders we tested completed the task in only 1 minute so the smoothies they produced were perfectly ice-cream-like (for instance, the Ninja Fit, the NutriBullet, and the Ninja BN401)

Even worse, the blender itself couldn’t run smoothly, as opposed to the prior test with protein shakes. The fruits were so solid that the blades couldn’t power through so we had to intervene multiple times by shaking the cup vigorously. Nonetheless, we believe this blender still makes sense for all of us when it comes to preparing small batches of smoothies as long as our ideas of drinks involve fresh fruits instead of frozen ones.

  • Suction:

The KOIOS Bullet brought all the ingredients together for a great-tasting smoothie in one minute and twenty seconds. Of all the similarly-priced blenders we tested, it was the only one that could liquify frozen ingredients that quickly. Most were 20-40 seconds slower, such as the Black+Decker, but that can make a difference; frozen foods thaw quickly at room temperature, so the longer you blend, the more your smoothie will be diluted. 

Simply put, the quicker performance of the KOIOS made for a thicker and more ice-cream-like smoothie. Chilly and fresh enough to quench our thirst, it also retained the texture that people look for in frozen fruit smoothies.

PopBabies Portable Blender Fibrous Greens Test
  • Blending Time: 20 seconds
  • Result: Very Coarse

It is unclear why the PopBabies blade failed to spin at the outset of our test, but it is possible due to the small size of the blending cup and the large amount of greens we used. To get the food to circulate properly, we had to shake the cup vigorously, which was time consuming and left us underwhelmed, though, after several attempts, we finally got the blender to run for the required 20 seconds. Following this, we strained the mixture through a mesh strainer and were dismayed to find a significant amount of pulp still remained. This indicated that the blender didn’t extract the full range of nutrients and flavors from the greens. Apparently enough, if your aim is to maximize the nutritional value of your vegetables, this blender may not be an ideal choice.

  • Blending Time: 20 seconds
  • Result: Very Coarse

We evaluated how well this blender handled fiber by blending kale, celery, spinach, and water for 20 seconds. The mixture came out grainy with a substantial amount of partially blended particles. Then, we drained it through a mesh strainer and examined the pulp. It looked like green sand with a moderately coarse consistency. We didn't taste the mixture prior to draining, but this coarseness, together with the volume of pulp, meant this blender failed to extract most of the flavor from the greens. 

We can’t say for sure if more blending time would improve the final result, but can conclusively say that 20 seconds worth of blending is not enough. By comparison, the Ninja Fit did the same job much better, leaving behind a significantly smaller amount of visible flakes. 

Our conclusion is that the KOIOS is just mediocre for blending leafy veggies. If you want to avoid leafy chunks in a quick high-fiber beverage, this is not the blender for you.

Crushed Ice

Crushed Ice Cubes
  • Ice Fineness: Failed
  • Unblended Ice: 100% of 6 oz

Given our experience with the blender in previous performances, it would have been reasonable to have low expectations for its capability in this test. However, we still gave it a fair shot. 

And again, this blender became obstructed by the ingredients even when we had tried hard to shake the cup repeatedly. To be fair, though, personal blenders like this one are not designed for heavy-duty tasks like crushing ice due to their lack of power. Pushing your device beyond its limits can cause wear and tear that will inevitably impact its overall performance, even in more standard blending tasks. If you want fluffy, snow-like crushed ice or desire to incorporate ice into your smoothies, it may be worth investing in a high-performance blender, such as the Ninja Nutri Auto-IQ.

  • Ice Fineness: Coarse
  • Unblended Ice: 77% of 6 oz

In this test, its performance was lackluster. The machine itself is incapable of crushing ice cubes. In fact, attempting to do so is not a good idea; the heavy-duty task can take a toll on your device and impair its performance in more ordinary blends.

Build Quality

The motor base and blending cup of the PopBabies blender.

The PopBabies blender comes across as inexpensive, with the use of cut-rate materials. There are a lot of plastic parts that look cheap and are prone to scratching. Even after taking care to avoid using abrasive cleaning tools, we found multiple little scratches appeared on both the inner and outer surfaces. We were also disappointed to find that the cup did not hold up well over time as it somehow became cloudy with use, detracting from the overall appearance of the blender. The blade is adequate for the blender's price range, but it still lacks the sturdiness necessary for consistent performance found on higher-priced models.

Build quality is moderate, with a body mostly made of plastic. The stainless steel blades look promising in terms of durability and capability while the motor base is rather flimsy. However, despite that, this blender stands very firmly during operation. It doesn’t jump around while handling solid foods like most mid-range counterparts such as the Magic Bullet

We like the metal surface on the front of the motor base. It gives our blender a more attractive appearance and better quality feel. After a couple of months in the lab, this surface still retains its original shine — even after the occasional cleaning with a metal scouring pad.

The PopBabies features a stainless steel blade assembly that is noticeably short and not very sharp compared to other personal blenders. While it may offer some benefits, we questioned whether this design could provide sufficient contact between the blades and ingredients for quick and even blending, and our experience with the blender confirmed that it was not as impressive as it may have appeared on paper. Furthermore, the blade assembly is permanently attached to the motor base, unlike most personal blenders. This makes it more challenging to clean the blades thoroughly, especially on the undersides.

The KOIOS Bullet comes with two extractor blades: one is flat and the other shaped like a cross. 

The flat blade has two dull prongs tilted slightly upwards and is only compatible with the short blending cup. We haven’t performed any tests on it, but believe this add-on will be handy for grinding hard ingredients like coffee beans, raw nuts, and whole grains. The blender’s mighty motor and consistent performance suggest it should be able to handle such ingredients.

Most of your blended treats will be best served by the cross blade. With six sharp prongs, it contacts more food at any given moment, resulting in finer outcomes and faster blending times. That being said, it looks less sturdy than some models (particularly the Ninja Fit). More prongs also means you’ll have more nooks and crannies to weave in and out of when it comes to cleaning.

The motor has a peak power output of 175 watts. It has a 20-second idle blending time and shouldn’t run continuously for a long time per interval. In case it goes beyond the idle time frame, the blender will automatically stop and you will have to press the switch again should you want to continue blending. The safety mode is critical in preventing overloading and subsequent damage to the blender's components. Other blenders may rely on silicone feet for stability, but this model defies convention. Despite lacking this feature, we found it remained remarkably stable on the counter during all of its testing performance, with no significant movement to report. It's a small detail, but one that speaks to the blender's usability.

The main housing of the KOIOS Bullet is made from medium-grade plastic, except for the front surface. It is a little smaller than other personal blenders, but could surprisingly tackle our tests without slipping or rocking around on the counter thanks to the four rubber feet at the bottom. 

Most models around this price cannot run continuously for more than one minute because the motor can overheat. The KOIOS Bullet is not an exception despite the fact that it’s equipped with many ventilation holes for better heat dissipation. If your drinks demand a longer blending time, make sure you let your machine cool down for 20-30 seconds after each 1-minute interval.

The blender comes with a 16-ounce capacity cup made of AS material. After rigorous testing, we found some areas being scratched, but it didn't affect the blender's performance in any way. The cup's lid provides a tight seal that prevents leaks, even during vigorous shaking or when the cup is turned upside down. To ensure optimal safety, it's essential to keep the lid securely closed and avoid adding ingredients while the blender is in operation. Additionally, the cup's small opening can make adding ingredients a bit challenging, but the included rubber funnel helps to prevent mess and spills.

Hands-Free Operation

5.7

The PopBabies personal blender simplifies the blending process by allowing users to hit the power button instead of continuously holding it, as required by most traditional personal blenders. However, the device's cross blade is prone to clogs, which may impede the blending process when using solid ingredients such as hard nuts and root vegetables. Therefore, close monitoring of the blending process is necessary to detect obstructions early and prevent damage to the device. 

In addition, the blender's automatic shut-off feature after 20 seconds of operation may inconvenience users as they have to press multiple times to resume blending, leading to a potentially impaired end-product quality. All things considered, hands-free operation alone cannot guarantee optimal convenience, and users must remain vigilant throughout the blending process.

You can’t walk away while the KOIOS Bullet does its job the way you might with a full-sized blender. It requires you to keep a hand on it the whole time. Plus, you may occasionally need to pause to remove the cup and give it a thorough shake.

Particularly in the smoothie test, frozen fruits got stuck under the blade and jammed it up. To even out the blend, we had to shake the cup after every 20 blending seconds. It gave us a good smoothie in 1 minute 20 seconds worth of runtime, so the process demanded four intervals total. Reviewers make a fuss about the repeated delays, but they’re a common occurrence among personal-size blenders. As long as you’re willing to spend an extra minute or two in the kitchen, it shouldn’t be a big deal.

Assembly

10

Assembling the lid, cup, and motor is a simple task. Our recommendation is to attach the lid to the blending cup first, then secure the cup to the motor. However, keep in mind that the force required for tightening may pose a challenge for individuals with oily or wet hands. Furthermore, there is no audible "click" or visual cue to indicate whether the assembly was successful. The only way to know for sure is to press the power button. It's also important to note that simply tightening the cup to the motor for operation can be a safety risk, as it can easily be done by a child.

Disassembling the blender is equally effortless, just reverse the assembly process.

Setting up this blender is a breeze. After twisting the blade assembly onto the cup, you’ll need to flip the cup over and place it securely onto the motor base, aligning the cup’s protrusions with the grooves inside the motor base. To start blending, gently push the cup down as long as you desire. Once finished, release the cup from the motor base and unscrew the blade assembly.

7.0

Cleanability

9.5

The lid, funnel, and blending cup can be safely placed on the top rack, but it's recommended to wash them by hand with warm, soapy water to prevent rapid degradation. However, it can be a bit challenging, especially when it comes to cleaning the blade's undersides. The blade is permanently attached to the cup, making it difficult to clean its nooks and crannies. Not to mention, the small opening of the cup makes it hard to reach the blade. In this case, a bottle-cleaning brush is essential to ensure that the blade assembly is entirely free of any food debris.

We've also tried a water-only cleaning method, where we fill the blending cup half full with water and let it blend itself to remove food residues from the blade. However, we found that this method wasn't as effective as manually cleaning the blade under running tap water with a brush. This is especially true if you're dealing with tougher residues that the self-blending action alone can't remove.

Of all the blenders we tested, the KOIOS is the only one with a blade that can be separated from its plastic base. It goes without saying, this can be a life-saver, especially since the blade assembly is not dishwasher safe. 

To remove the blade attachment from the base, push the blade gear forward until it falls out. Note that these two pieces screw very tightly together through a white gasket ring so you'll have to apply a significant force, which can be a challenge if your hands are weak or in pain. 

Once you’ve separated the blade attachment, plastic base, and gasket ring, they can be washed off easily with soapy water. The only parts that are tricky to clean are the blade’s undersides, but the included small brush will make life easier on you. 

The other pieces, including the lids and blending cups, can be put in the dishwasher.  For manual cleaning, just rinse them with soapy water.
