SMT (Surface-Mount Technology)
The manufacture of the PORTABLE MOSQUITO REPELLER
with microelectronic SMD (Surface-Mount Device) made it
possible to obtain a compact size with high performance.
Demitto. 1 battery = 8 months = 1,000h
The efficiency of the PORTABLE MOSQUITO REPELLER
design and the consumption optimization makes it possible
for only one LR44 1.5 V battery to last for 1,000 hours
(equivalent to 8 months running 4 hrs/day).
