What the Braun AIO3540 hair trimmers/clipper Black, Grey 14 Nickel-Metal Hydride (NiMH) is worth

The Braun AIO3540 is a cordless multi-function trimmer supplied with 8 accessories: 5 combs (head, beard, body), a precision trimmer for nose, ears, eyebrows and moustache, a cleaning brush and a storage pouch. It offers 14 length settings between 0.5 mm and 2.1 cm.

Its 50 min runtime falls below the market median of 120 min, and the 10 h charging time far exceeds the current standard of 1.5 h. The NiMH technology explains these modest performances. However, the 0.5 mm cutting precision and number of settings match category standards. The overall 58/100 score reflects this imbalance between complete equipment and limited energy performance.

This model suits users seeking a versatile kit for hair, beard and precision areas, provided they accept limited runtime and overnight charging. Its 110 g weight and compact dimensions (165 x 42 x 41 mm) ease handling. The universal 100-240 V power supply enables travel use.

Frequently asked questions

Answers drawn from this model’s datasheet.

The Braun AIO3540 offers 50 min battery life, which is less than the market median of 120 min. This short battery life requires more frequent charging, especially since charging time reaches 10 h.

The kit includes 8 accessories: 5 combs (beard, body, head), a precision trimmer for beard, ear, eyebrow, face, moustache and nose, a cleaning brush, a storage pouch and a charger.

With a battery score of 47/100 and NiMH battery technology, it is more suitable for occasional use. The 50 min battery life and 10 h charging time limit intensive daily use.
