A power inverter can be a versatile tool, allowing you to convert DC from a battery into AC for various applications. From small electronic devices to limited power tools, this compact inverter provides a portable power source. In this guide, we will discover what all will a 400 Watt power inverter run.
What Will a 400 Watt Power Inverter Run?
A power inverter with a rating of 400W is capable of delivering 400 Watts at its maximum capacity, enabling you to operate multiple appliances with a cumulative power consumption of 400W simultaneously. Some examples of appliances that a 400-Watt inverter can run include an air cooler, a laptop, a dehumidifier, a fan, a cordless drill charger, a refrigerator, an aquarium pump, and a radio. Additionally, you can also connect accessories and lights to the inverter. To optimize the performance of your 400 Watt inverter, it is essential to ensure that the power output matches the capacity of your battery. Now, let’s see what devices can be powered by a 400 Watt inverter.
What Appliances Can a 400 Watt Inverter Run?
This power inverter has a maximum capacity of 400 Watts, allowing it to operate a variety of appliances as long as their power consumption remains below this limit. If the total power requirement exceeds 400 Watts, a larger system would be necessary. Here are some common household appliances that a 400 Watt inverter can run-
- TVs: 80 to 300 Watts
- Blender: 400 Watts
- Food mixer: 300 Watts
- Chest freezer: 350 Watts
- Laptop: 100 to 200 Watts
- Electric blanket: 200 Watts
- Fan: 50 to 150 Watts
- Lights: 60 Watts
- 12V fridge: 60 Watts
- Blu-Ray player: 35 Watts
- Mobile phones: 2 to 5 Watts
In addition, other devices that can be powered by a 400 Watt inverter include an air cooler (65W), aquarium pump (25W), cordless drill charger (70W), and a dehumidifier (240W). It’s important to check the labels of other appliances and devices to determine if they can be powered by this inverter.
Please note that the wattage provided for each appliance here is a general reference and may vary. Some appliances like blenders can consume less than 400 Watts on low settings but may require more power on high settings. Laptops designed for gaming typically consume more power compared to those intended for business purposes.

Will a 400 Watt Inverter Run a Small TV?
Yes, a 400-Watt inverter can run a small TV, particularly the newer models that tend to be more energy-efficient. Nonetheless, the appropriate size of the inverter required to run a TV depends on the power consumption of the specific TV, which is determined by factors such as the size and type of the TV. After learning what will a 400 Watt inverter, let’s see how many amps a 400 Watt inverter draws when running.
How Many Amps a 400 Watt Inverter Draws When Running?
In order to determine the amperage for a given wattage, you need to know about the voltage at which the power is being supplied. The amperage can be calculated by dividing the power (measured in Watts) by the voltage (measured in volts).
Let’s consider a standard voltage of 120 volts for this illustration. Using this information, we can calculate the amperage for a power of 400 Watts as follows:
Amperage = Power (Watts) / Voltage (volts)
Amperage = 400 Watts / 120 volts ≈ 3.33 amps
Hence, at 120 volts, a power of 400 Watts is approximately equivalent to 3.33 amps. After finding out how many a 400 Watt inverter draws when running, let’s also see the number of batteries needed for a 400 Watt inverter.

How Many Batteries Do I Need For a 400 Watt Inverter?
The number of batteries you need for a 400 Watt inverter depends on factors like battery capacity, voltage, system efficiency, and power duration.
Let’s assume we have 12-volt lead-acid batteries with a capacity of 100Ah. If we want to power a device for 2 hours, we would need 800 Watt-hours of energy (400 Watts x 2 hours).
Dividing the total energy by the battery voltage, 800 Watt-hours / 12 volts = 66.67 Ah.
Since each battery has a capacity of 100Ah, at least one battery would be required to meet the energy demand.
However, this calculation is simplified and doesn’t consider factors like battery efficiency and discharge rates. It’s recommended to consult professionals or use battery sizing calculators for accurate results based on specific requirements. After this, let’s see how long will a battery last with a 400 Watt inverter.
How Long Will a Battery Last With a 400 Watt Inverter?
The duration of battery life when using a 400 Watt inverter is influenced by various factors such as inverter efficiency, battery capacity, and the power consumption of connected devices. As per some sources, a 100Ah lithium battery can sustain a 400W appliance for approximately 0.25 hours or 15 minutes before requiring a recharge.
While a 400-Watt power inverter has its limitations, it can still run a variety of devices that are essential for everyday use. From charging laptops and smartphones to operating small kitchen appliances or running power tools with lower wattage requirements, this compact inverter proves to be a reliable companion.
