Our Expertise
I’ve been testing kitchen gadgets for over 15 years now. I focus on portable blenders because I use them daily.
I’m a fitness enthusiast who drinks protein shakes every morning. I also love making fruit smoothies after my gym sessions.
For this guide, I bought all three blenders with my own money. I tested each one for 30 days straight.
I made over 90 smoothies during my testing period. I tried different ingredients in each blender. I also cleaned them multiple times to see how easy they are to maintain.
I took notes on battery life, blending power, and ease of use. I measured noise levels and blending times too.
This guide shares my real experience with these products. I’ll tell you what worked and what didn’t.
Our Top Picks
After testing all three models, here’s my quick ranking:
Best Overall: Devan Portable Blender – It has the best build quality and performance.
Best Value: DENOKIN Portable Blender – Great features at an affordable price point.
Best Premium: NexaEase Portable Blender – Comes with an insulated sleeve and extra accessories.
Each blender has its strengths. I’ll explain everything in detail below.
Why You Need a 20 oz Portable Blender
A 20 oz blender is the perfect size for one person. It’s not too big and not too small.
I used to carry a large blender to work. It was heavy and took up too much space in my bag.
These portable models changed my routine completely. Now I can blend fresh smoothies anywhere.
The 20 oz capacity gives you enough drink for one meal. It’s ideal for breakfast shakes or post-workout drinks.
You can use these blenders at:
- The gym
- Your office
- The park
- The beach
- Camping trips
- Road trips
They’re also great for small kitchens. You don’t need counter space for a big blender anymore.
What I Tested For
I focused on several key areas during my testing:
Blending Power: Can it crush ice? Does it blend frozen fruit smoothly?
Battery Life: How many smoothies can you make on one charge?
Build Quality: Does it feel durable? Will it last long?
Ease of Use: Is it simple to operate? Can you blend with one hand?
Cleaning: How easy is it to wash? Does it have hard-to-reach spots?
Portability: Is it light? Does it fit in a bag easily?
Safety Features: Does it have auto-shutoff? Is there leak protection?
Value: Is the price fair for what you get?
I gave each blender a score in these categories. This helped me compare them fairly.

I tried frozen blueberries next. This is where I learned the upside-down trick.
When you flip it while blending, the frozen fruit doesn’t get stuck. This tip is mentioned in the manual.

Tips for Getting the Best Results
Liquid First
Always add liquid to the blender first. This helps the blades move freely.
I use about 1/3 cup of liquid as a base. Water, milk, or juice all work.
Cut Ingredients Small
Chop fruits and vegetables into small pieces. This makes blending easier.
I cut everything into 1-inch cubes. This prevents the blades from jamming.
Don’t Overfill
Never fill past the max line. I learned this the hard way.
Leave about 1 inch of space at the top. This allows ingredients to move.
Use the Right Mode
Soft ingredients work with regular blend mode. Use pulse mode for ice and frozen items.
I double-click for pulse mode with frozen berries. It works perfectly.
Flip When Needed
If ingredients get stuck, turn the blender upside down. This helps with frozen items.
I do this with the DENOKIN especially. It prevents blade jamming.
Clean Immediately
Don’t let ingredients dry in the blender. Clean right after use.
I rinse mine within 5 minutes of blending. This prevents stubborn stains.
Common Mistakes to Avoid
Using Too Little Liquid
The blades need liquid to work properly. Don’t blend dry ingredients.
I once tried to blend just protein powder. The motor struggled badly.
Blending Hot Liquids
These blenders are for cold drinks only. Never add hot coffee or soup.
The heat can damage the plastic and create pressure. Stick to cold ingredients.
Ignoring the Manual
Each blender has specific instructions. Read them carefully.
I missed the upside-down tip for DENOKIN at first. The manual explained it clearly.
Not Charging Fully
Always charge fully before first use. This optimizes battery life.
I now charge mine overnight before testing. It ensures consistent performance.
Forcing the Blades
If the blades stop, don’t force it. Turn off and check for jams.
I once kept pushing with frozen fruit stuck. It’s better to stop and fix it.
Maintenance Tips
Regular Cleaning
Clean after every use. This prevents bacteria growth.
I use warm soapy water each time. It takes only 2 minutes.
Deep Clean Weekly
Take apart the blade assembly once a week. Clean each piece separately.
I use a small brush for hard-to-reach spots. This removes buildup.
Check Seals
Inspect rubber seals regularly. Make sure they’re intact.
I check mine every few weeks. Damaged seals can cause leaks.
Charge Properly
Don’t let the battery drain completely. Charge when it hits 20%.
I charge mine every 3-4 days. This maintains battery health.
Store Dry
Always dry the blender before storing. Don’t put it away wet.
I air dry mine completely. This prevents mold and odors.
Frequently Asked Questions
Can I blend ice in these blenders?
Yes, all three can handle small ice cubes. The NexaEase and Devan work best with ice. Use pulse mode for better results. Cut ice into small cubes for easier blending.
How long do the batteries last?
DENOKIN gives 10 smoothies per charge. Devan provides 12 smoothies. NexaEase offers 14 smoothies. Actual results depend on what you blend. Tougher ingredients drain the battery faster.

No, none of these are dishwasher safe. Hand washing is required for all models. The good news is they’re easy to clean by hand. Just blend with soapy water and rinse.

No, these blenders are designed for cold ingredients only. Hot liquids can damage the plastic materials. They can also create dangerous pressure buildup. Stick to smoothies and cold drinks.

The NexaEase is the loudest due to its power. The Devan is moderately loud. The DENOKIN is the quietest. None are silent but all are acceptable for home use.
Do I need to add liquid to blend?
Yes, always add liquid first. This helps the blades work properly. Use water, milk, juice, or yogurt as your base. Without liquid, the motor will struggle.

USB-C charging (NexaEase) takes about 2 hours. The other two take 3-4 hours with standard USB. Always use the provided cable. Charge fully before first use for best results.
Final Verdict
After 30 days of testing, here’s my honest opinion:
