XTAR VX4 Visible Mixer

Name: XTAR VX4 Visible Mixer
Brand: XTAR

Specialist pick: One four-bay unit handles NiMH and lithium cells while adding discharge-capacity grading; NiMH stops at 0.5 A and thin AAA cells may need contact adjustment.

WHY THE PRICE IS JUSTIFIED

It combines four independent bays, NiMH charging limited to 0.5 A, selectable lithium currents, capacity grading and broad chemistry support. Independent reviews found voltage readings within ±0.01 V and generally correct NiMH termination; capacity-accuracy figures available from testing are not NiMH-specific.

MATERIALS

HousingABS

A retailer describes the housing as robust ABS, supporting a conventional impact-resistant consumer enclosure.

CRITERIA

8/10

Charge Termination

Independent testing found generally correct NiMH termination around 1.50–1.52 V.

9/10

Independent Channels

Independent review describes four independent bays.

6/10

Thermal Control

No verified temperature display or exact-model controlled thermal result was found.

6/10

Capacity Accuracy

Capacity grading exists, but independent accuracy evidence is not NiMH-specific.

7/10

Usability Fit

Clear display and easy insertion help, but AAA contact manipulation and automatic modes reduce convenience.

7/10

Build Reliability

Retailer describes robust ABS; teardown reports generally good contacts but a less-solid negative slider.

7/10

Charge Efficiency

NiMH is limited to 0.5 A, while lithium charging supports higher selectable currents.

IDEAL FOR

·Users combining NiMH and lithium cells
·Users wanting capacity grading without MC3000 complexity
·AA/AAA users who prefer a detailed display

NOT FOR

·Users requiring low-current AAA selection
·Users needing verified NiMH capacity accuracy
·Users wanting a small travel charger

DESIGN & ERGONOMICS

Large but clear two-decimal display, easy battery insertion and visible status information. AAA contacts may need manipulation, and there is no temperature or internal-resistance display.

LONGEVITY

The ABS housing and conventional slider design suggest ordinary consumer durability, but no warranty, spare-parts or repair evidence was supplied. Contact behavior with thin AAA cells is the main practical uncertainty.
