For one watermelon cooler at a time, a personal-cup blender is a sensible starting point when worktop space is tight. Choose a jug blender if you regularly make several servings, checking its working capacity and the exact model's ice guidance; a portable blender makes more sense when one drink needs to travel, but its smaller vessel is less convenient for shared batches.
Start with how many drinks you make at once, then decide whether the blender needs to stay on the worktop or travel with you.
If you usually blend one watermelon cooler, a personal-cup format lets you make the drink in a lidded cup without storing a large jug. A 680 ml cup and to-go lid are listed for the NutriBullet 600 Series Deluxe; check the dimensions of whichever model you choose against your own worktop and cupboard.
If several glasses need filling in one session, look at a jug's usable working capacity rather than its total volume. Tefal UK Shop states a 1.25 L working capacity for the Blendforce II Plastic BL420840 and describes ice-crushing capability for that model.
A cordless blender can make sense when an individual cooler needs to be blended away from a socket. The Ninja Blast BC151UK is a compact 0.53 L example, but that vessel size means repeating the process for a group.
For a small kitchen, settle the space and serving-size questions before comparing extras such as cordless operation. If ice is part of the drink, check the exact model's instructions rather than relying on its motor rating.
| Concern | What to check | Who this matters to |
|---|---|---|
| Worktop and storage space | Measure the assembled width, depth and height, including the cup or jug in its operating position. | If everyday worktop space is scarce, I need a blender I can leave out or put away without displacing other equipment. Around 36% of consumers would put compact storage first. |
| Ice for a colder drink | Check the exact model's ice-crushing guidance and any limits on ice size or quantity. | When I want an iced watermelon cooler, I need to know whether my chosen model is intended to handle the ingredients. Ice handling would be the leading concern for around 29% of consumers. |
| Usable batch capacity | Compare the stated working fill level with the amount of watermelon, ice and liquid needed for your servings. | Making drinks for several people, I would rather prepare a shared batch than refill a personal cup repeatedly. Around 21% of consumers would prioritise batch capacity. |
| A drink-ready vessel | Check cup capacity, lid design and, for cordless models, how the blender charges. | If I take one cooler away from the kitchen, a compact lidded vessel matters more to me than a large jug. Portability would come first for around 14% of consumers. |
Fruit, liquid and ice need room during blending. Tefal UK Shop gives the Blendforce II Plastic BL420840 a 1.75 L jug but a 1.25 L working capacity; those figures are not interchangeable.
Plan the recipe around the working capacity and follow the fill markings and instructions for the exact blender.
A small vessel can mean repeated blending when more than one glass is needed. The Ninja Blast BC151UK's stated capacity is 0.53 L.
Choose a portable format chiefly for an individual drink; compare jug working capacities if shared coolers are routine.
Motor ratings alone do not establish whether a particular blender is intended to process ice. Tefal UK Shop and SharkNinja UK describe ice-related uses for specific models, not for every blender in their ranges.
Check the manufacturer's instructions for your exact model and the ice quantity or preparation your recipe requires.
A blender can fit across a narrow worktop yet be awkward below a wall cupboard. SharkNinja UK lists the Ninja BN750UK at 44.5 cm high, while the NutriBullet 600 Series Deluxe is listed with a height of 34.5 cm.
Measure the vertical space where you will assemble, use and store the appliance, allowing for its lid and cup or jug.
These examples illustrate different blender formats; the dimensions and capabilities below belong to the named models, not to every product from each brand.
The 600 Series Deluxe illustrates the personal-cup route for one drink where a narrow base and lidded cup matter.
The Blendforce II Plastic BL420840 illustrates a jug option for shared watermelon coolers, including drinks made with ice.
The Blast BC151UK and 2-in-1 BN750UK illustrate separate choices: a portable individual vessel or a larger blender with a personal-cup option.
These choices span a portable cup for one drink, personal-cup blenders and a jug blender for larger batches. Compare the usable fill guidance and assembled dimensions of the exact model before deciding what fits your kitchen and recipe.

Consider this cordless cup if you make one watermelon cooler and want to take it with you; a shared batch would take repeat blends.
The product name specifies a 475 ml cup, to-go lid and USB-C charging cable. Check its assembled size against your storage space and follow the manufacturer's instructions if adding ice.

This personal-cup format suits a drink made at home without bringing out a full-size jug.
The product name specifies 900 ml and 900 W. Check the cup's maximum fill guidance before planning a watermelon-and-ice recipe, and measure cupboard clearance with the cup fitted.

Its personal-cup format is worth considering when you usually make an individual cooler rather than a jug for several people.
The product name specifies a 900 ml cup, 1200 W and two blending options. Confirm the assembled dimensions, safe fill level and manufacturer's ice instructions for your intended drink.

A jug format is more relevant when you often prepare watermelon coolers for more than one person, provided it fits your worktop and storage space.
The product name specifies a 1.5 L glass jug, 600 W, two speeds and a smoothie-to-go bottle. Use the manufacturer's working fill guidance rather than treating the full jug volume as the usable batch size.
Choose a personal cup if you usually make one watermelon cooler and have little space; choose a jug if several glasses are routine. For scale, a 680 ml cup is listed for the NutriBullet 600 Series Deluxe, while Tefal UK Shop gives the Blendforce II Plastic BL420840 a 1.25 L working capacity.
No—check the instructions for the exact model before adding ice. Tefal UK Shop describes ice crushing for the Blendforce II Plastic BL420840, and SharkNinja UK describes crushed-ice drinks for the BN750UK; neither statement establishes what another model can handle.
Clean the parts that contact the watermelon cooler according to the manufacturer's instructions, paying attention to the cup or jug, lid and blade assembly. The NutriBullet 600 Series Deluxe cups, lids and blades are listed as dishwasher safe; check the cleaning directions for your exact model before putting parts in a dishwasher.
Check whether replacement parts and repair support are available for the exact model you are considering. Pay particular attention to parts you may need to remove for cleaning, such as the jug, lid and blade assembly.
