WHAT TO LOOK FOR

Steam beats contact & battery on evenness
02
Power source
Cable means full power, no degradation
03
Food quality
Moisture kept in, not driven out
04
Payback
Cost against what you save on lunch

THE FOOD TEST
We reheated the same chicken tikka in every box. Steambox was the only one where the chicken stayed tender.
THE DAILY DIFFERENCE
Cable vs battery
BATTERY
Fades with age
Charges overnight, weakens as it ages, weaker heat over time.
CABLE · STEAMBOX
230W
Full power, every use
Nothing to charge, nothing to degrade — day one and day five hundred.
