Recommended Battery for BESTEK MRI5011BU 500W Power Inverter
The recommended battery for BESTEK MRI5011BU 500W Power Inverter depends on the user's need to power 110V AC loads - time and actual wattage.
For example, if the BESTEK MRI5011BU 500W Power Inverter is connected the cigarette lighter port, it may draw up to 10 Amps continuously.
One hour of such load can discharge the car's battery by 10Ah, which should not be a problem for modern car battery with 50+ Ah capacity, even if it is starting battery, not designed for deep cycle applications.
However, few hours of such use may discharge the battery almost fully, preventing it from cranking the engine next time the user tries it.
When going camping, hunting, fishing and simply enjoying outdoors, it is a good practice to have a spare, deep cycle battery and use it for powering inverters and required 110 volts loads.
For example, Mighty Max ML75-12 12V 75Ah Battery is able to provide ~580 watts for one hour constantly (586.2W down to 9.6 volts, 543.0W down to 10.8 volts), allowing the BESTEK MRI5011BU to operate at full power for an hour.
If longer operating times are needed, larger and heavier batteries are required, unless more expensive (at least initially) lithium batteries are used.
Long Story Short: BESTEK MRI5011BU 500W Power Inverter is one of the most popular power inverters in it class - it is well designed and built unit, reliable and robust and can be used in various situations, in the car, on the boar, during camping, etc.
If you are looking for versatile power inverter in the 500W range, consider this unit - it has been tested by countless users and it passed the tests with flying colors.
