Bestek MRI5011BU Power Inverter Features and Specifications
Bestek MRI5011BU features a strong aluminum body, making it rather resilient to mechanical impacts and vibrations. Physical dimensions are 7.28 x 4.33 x 2.44 inches (185 x 110 x 62 mm) and it weighs ~1.5 pounds (~686 grams).
Bestek MRI5011BU power inverter comes with several protective features including overload protection, short circuit protection, over-voltage protection, low-voltage protection, overheating protection, and anti-reverse polarity protection, making it a very safe power inverter to use.
Input voltage is 11-15 volts, allowing the unit to be powered by various 12V lead-acid and lithium batteries.
The unit is also protected with 40 Amps fuses, with two spare fuses as well.
Bestek MRI5011BU power inverter comes with two types of input cables:
- cables with alligator battery clamps allow the user to connect the Bestek MRI5011BU power inverter directly to 12V batteries. In such configuration, the unit is able to provide 500W continuously and 1000W surge.
- cables with the cigarette lighter plug allow the user to connect the Bestek MRI5011BU power inverter directly to the car's 12V port. In this configuration, the unit is able to provide at most 120-150W - power is actually limited with the circuit breaker of the car's 12V port, which is usually 10 Amps.
Since it is intended to be used in cars, in order to limit the amount of created noise, fan speed is variable and adjusted according to the load automatically. Also, when the unit is connected to the battery/car's 12V port, it should be turned off when not in use for a longer period of time.
Output ports include:
- two 5.0V 2.4 Amps USB ports (4.8 Amps total),
- two 110V AC ports with modified sine wave output.
Bestek MRI5011BU power inverter is suitable for powering most laptops, tablets, and similar units, home appliances with power up to 500W, etc.
But, some sensitive devices and appliances may require pure sine wave power inverters to operate properly.
Bestek MRI5011BU power inverter is an energy-efficient unit with an efficiency of ≥83%.
When the Bestek MRI5011BU power inverter is used in the car, it is recommended to have the car engine turned on in order to prevent the power inverter from draining the battery completely.
However, Bestek MRI5011BU power inverter is commonly used when camping, in emergencies, and in similar situations.
For many reasons, it is very important to calculate how long a battery can power this unit, depending on its load.
If the Bestek MRI5011BU power inverter is being powered by Renogy 12V 200Ah RNG-BATT-AGM12-200 AGM Deep Cycle Battery, with an output of ~350 watts, then the battery must provide:
P = 350 / 0.83 = ~420 watts
If we check the constant power discharge charts of this battery, this battery is able to provide 435 watts for 4 hours, down to 11.1 volts - such battery voltage will not trigger automatic under-voltage protection.
Bestek MRI5011BU power inverter comes with a car cigarette lighter plug (27.5 inches, ~70 cm) and a pair of alligator battery clamps (24 inches, ~61 cm), and a pair of spare 40A fuses. Also, Bestek MRI5011BU power inverter comes with 18 months warranty.
Note: Bestek MRI5011BU power inverter is very simple to use power inverter, but when it arrives, be sure to read the manual - better safe than sorry.
Long Story Short: Bestek MRI5011BU power inverter is a very popular unit due to its affordable price, and simple and reliable operation.
If You are looking for a 12V power inverter and your devices support the use of a modified sine wave power inverter (most devices do!), consider this unit.
