XTAR L4 Pro

Name: XTAR L4 Pro
Brand: XTAR

USB-C and independent charge, discharge and refresh modes fit a compact €13.40 body; fixed 0.5 A current and limited termination evidence keep it below simpler documented rivals.

WHY THE PRICE IS JUSTIFIED

At a very low price it provides four independent channels and discharge/refresh modes. Independent testing of four IKEA Ladda cells found 2424 mAh average versus 2443 mAh using STENKOL, supporting practical charging equivalence rather than a timer-only design. Full NiMH termination waveform data is not available.

CRITERIA

7/10

Charge Termination

Published NiMH cutoff is 1.45 V ±0.1 V; independent testing found practical capacity equivalence but no full termination trace.

9/10

Independent Channels

Independent testing says all four battery slots run independently.

6/10

Thermal Control

No independent controlled thermal measurement or temperature display was found.

3/10

Capacity Accuracy

It has no analyzer capacity function; the comparison measured delivered charge, not calibrated discharge capacity.

8/10

Usability Fit

USB-C, compact size and Charge/Discharge/Refresh modes are convenient.

7/10

Build Reliability

Current retailer availability and practical independent testing support ordinary consumer use; internal construction is undocumented.

7/10

Charge Efficiency

Fixed 0.5 A charging is reasonable for most AAA but slower for high-capacity AA cells.

IDEAL FOR

·Budget-conscious AA/AAA users
·Users wanting refresh mode and USB-C
·Mixed NiMH and 1.5 V Li-ion AA/AAA users

NOT FOR

·Users needing selectable current
·Capacity analysis or internal-resistance measurement
·Users without a suitable USB power supply

DESIGN & ERGONOMICS

Small USB-C charger with compact slots and a basic status display. It is convenient and modern, but needs a separate 5 V/2 A supply and offers no selectable lower current for small AAA cells.

LONGEVITY

No verified spare-parts or repair information was found. USB-C reduces adapter obsolescence, but fixed-current electronics and undocumented serviceability leave long-term repair uncertain.
