Dumbbell Comparison
PowerBlock vs Nuobell: Which Adjustable Dumbbells Win?
Adjustable dumbbells save space and money versus a full dumbbell rack. PowerBlock and Nuobell are the two most popular options — but they take very different approaches. Here's which one deserves your money.
| Feature | PowerBlock | Nuobell |
|---|---|---|
| Design | Selector pin (cage) | Twist-handle |
| Weight Range | 5–50 lbs (expandable to 90) | 5–80 lbs |
| Increment | 2.5–5 lbs | 5 lbs |
| Change Speed | ~5 seconds | ~2 seconds |
| Feel | Block/cage (unusual) | Traditional dumbbell |
| Durability | Nearly indestructible | Plastic components |
| Drop Rating | Can survive drops | Do NOT drop |
| Price | ~$330–$450 | ~$745 |
PowerBlock: Ugly But Indestructible
PowerBlocks look weird. The cage design puts your hand inside a rectangular block, and they don't feel like traditional dumbbells. But here's the thing: they're nearly impossible to break. People have been using the same PowerBlocks for 15+ years. The selector pin mechanism is foolproof. And at $330–$450 for the base set, they're significantly cheaper than Nuobells. If durability and price matter more than feel, PowerBlock wins.
Nuobell: Feels Like a Real Dumbbell
Nuobells look and feel like traditional dumbbells. The twist-handle mechanism changes weight in under 2 seconds — the fastest in the industry. But that mechanism relies on plastic components that can break if dropped. For controlled accessory work (curls, presses, rows), they're perfect. For CrossFit or explosive movements, they're the wrong tool. At $745, you're paying for the best user experience in the category.
