Overview
This is a pair of adjustable dumbbells sold under the model DAJC-HB, in the 25 pound per side, round iron plate configuration Amazon labels as 5 in 1. That labeling points to five selectable plate combinations per handle. Total weight across the pair comes to 50 pounds.
The round iron plates and swap-style design point to a standard adjustable dumbbell kit rather than a fixed hex weight. The 5 in 1 tag most likely refers to five weight settings per handle rather than five separate accessories, though the listing doesn't spell out the exact increments.
- Iron round plates
- 25 lb per dumbbell in this configuration
- 5 in 1 adjustable design
- Sold as a pair, 50 lb total
Who it's for
Fits home lifters who want one pair of dumbbells that can step through several weight levels instead of buying multiple fixed pairs. Less useful for lifters who prefer a quick-change dial or clip system, since this listing doesn't detail how fast the plates swap.
Strengths and trade-offs
Drawn from this product's published specifications.
- Covers multiple weight settings from one pair
- Iron plates for a durable load
- Caps at 25 pounds per side
- Plate-swap speed isn't detailed in the listing
Performance notes
Weight change comes from swapping the round iron plates onto the handle by hand rather than turning a dial, so the 5 in 1 label reflects discrete plate combinations rather than continuous adjustment.
