The value of all the precious and essential things in the world
are appreciated only after those are unavailable.
So we decided
to make electricity of all thing to be used
whenever, wherever
in a lighter, more powerful, more safe and smarter way.

SMART

enables detailed setting for the device usage time and
alarms in case of danger such as overheating.
Controls the device and checks the status
by connecting to a smartphone with Bluetooth technology.

ECO FRIENDLY

No air pollutant emissions, no noise, and no odor made.

No more internal combustion engine!
Stop global warming

Gasoline generator

Difficulty in carrying and moving
Inconvenient to carry in weight and volume

Gasoline fuel use, toxic gas exhaust
Emissions of carbon monoxide and other toxic gases
Only for outdoor use

High noise
Approx. 70dB in IDLE mode and 78dB in load

Expensive maintenance costs
Gasoline must be filled up for each use and
regular engine oil and spark plug replacement is necessary
Periodic cleaning and maintenance for
combustion chamber and oil pipe is required

Low energy use efficiency
Fuel loss occurs for maintaining start condition
even when not using electricity

BASTRO

Easy carrying
Compact, portable and lightweight

No separate fuel use
No toxic substances and odors
Both indoor/outdoor use available

No noise
0dB in standby and in use
(heat dissipation fan when using an inverter)

No separate maintenance fee
Guaranteed life of the battery
based on normal charging is observed
Additional maintenance and parts replacement are not required

High energy efficiency
Low power dissipation in standby allows
high efficiency as it is consumed only as much it used.
