Can a Portable Power Station Run a Washing Machine?

A portable power station (PPS) is a portable battery pack that can provide electricity for electronic devices and appliances when grid power is unavailable. Unlike small portable chargers, a PPS is designed to power larger loads like household appliances, power tools, medical devices, and more.

A PPS consists of a large rechargeable lithium-ion battery, an inverter to convert DC power from the battery to standard AC power, and a control panel with various output ports. The battery capacity of a PPS is measured in watt-hours. Popular output ports include standard AC outlets, USB ports, a 12V car outlet, and DC ports.

PPS units have features to manage power input and output efficiently. This includes monitoring incoming and outgoing voltage, automatic shut-off when a device is fully charged, and delivering the proper wattage to connected devices. Many models can recharge quickly by plugging into AC power or using solar panels.

Larger PPS models with 1,000 watt-hours or more are capable of safely running appliances like mini-fridges, CPAP machines, and small washing machines. Small portable power stations under 500Wh are better suited for charging smartphones, laptops, lights, and other basic electronics when camping or during a blackout.

Types of Portable Power Stations

Portable power stations come in different types and sizes to meet various power needs. The two main factors that differentiate portable power station models are the battery technology and overall design.

Battery Technology

The most common battery types used in portable power stations are:

• Lithium-ion batteries - These provide high energy density, fast charging, long lifespan, and good performance. Lithium-ion batteries are lighter weight than lead acid.

• Lead acid batteries - Lead acid batteries are cheaper but much heavier. They have lower energy density and slower charging. Lead acid is more common in budget power station models.

Lithium-ion batteries are superior for portable power stations because of their light weight, fast charging, high cycle life, and efficiency. High-end models from Growatt utilize lithium-ion.

Integrated vs. Modular Design

There are two main portable power station configurations:

• Integrated - The battery, inverter, and outlets are all contained in one unit. Integrated PPS units are compact and simple to use.

• Modular - The battery is separate from the inverter station. Modular allows you to add extra batteries to increase capacity. However, it's less portable.

Integrated designs are best for smaller portable power stations under 1000W. Modular systems are better for large capacity home backup power.

Size and Weight

Portable power stations range from compact, lightweight models to larger stations weighing over 100 lbs. Smaller units under 30 lbs are easy to move and transport. Larger models have wheels for mobility.

The size and weight depends on the battery capacity, which ranges from 100Wh to over 2000Wh. Lightweight lithium-ion models can still store a lot of power. Make sure to choose a PPS size suitable for your usage needs.

Key Specs and Features of Portable Power Stations

Portable power stations are available in a range of capacities and with different features. Here are some of the key specs and features to look for when selecting a portable power station:

Rated Wattage Capacity

• The rated wattage, usually given in watts (W), indicates the continuous power a portable power station can supply.
• For running appliances like washing machines, look for models with at least 2000W, like Growatt INFINITY 1500 (2000W output) and Growatt INFINITY 2000 (2200W output). Higher-draw appliances may need 3000W or more.

Battery Capacity

• Battery capacity is measured in watt-hours (Wh). The higher the capacity, the longer a portable power station can supply electricity before needing a recharge.
• For a washing machine, look for 500Wh or higher capacity. 1000Wh+ is ideal for longer run times.

Output Ports

• Common output ports include AC outlets, USB ports, 12V car ports, and DC connectors.
• For a washing machine, prioritize models with at least one AC outlet rated for high wattage. Some units have multiple AC outlets.

Recharge Time

• Recharge time varies, from 1-2 hours up to 10+ hours depending on the model.
• Faster recharge times allow you to get back up and running quicker after depleting the battery.

Warranty

• Most portable power stations come with a 1-2 year warranty. Some offer 3-5 years.
• Look for at least a 1 year warranty from the manufacturer.

How Much Power Does a Washing Machine Use?

A standard washing machine uses around 850 watts while running for the wash and rinse cycles. However, at startup when beginning the spin cycle, a washer may surge up to around 1700 watts briefly.

For larger capacity washing machines, such as those over 4 cubic feet, the average running wattage can be around 1400 watts. The startup surge for bigger washers may reach as high as 2800 watts.

To calculate the total energy needed for your washing machine, take the running wattage and multiply it by the number of hours the washer cycles. For example, if your washer runs at 850 watts and goes through a 2 hour wash and rinse cycle, it would use 1700 watt-hours (850 x 2 hours) of energy. Add the short startup surge wattage as well. This gives you a rough estimate of the total power capacity your portable power station needs for running a washer.

How to Select a Portable Power Station for a Washing Machine?

When selecting a portable power station for running a washing machine, it's important to choose one with adequate capacity. The general recommendation is to get a PPS with at least double the running wattage of your washing machine. This provides enough of a buffer so the PPS isn't strained.

For example, if your washing machine is rated at 850 watts while running, you'll want a PPS with 1700+ watts of continuous output. Having extra capacity allows the PPS to handle the temporary surge when the washer motor first starts up, which can be 2-3x the running load. A 1700W+ PPS would have no problem covering an 850W running load and up to a 2800W starting load.

You also need to make sure the PPS has enough capacity for multiple cycles if you plan to run consecutive loads. A larger unit with 2000W+ continuous output would be ideal to run multiple washer loads back-to-back. This prevents the battery from being depleted too quickly.

When shopping for a portable power station for your washer, check both the continuous and peak wattage specs. Get a model rated to comfortably handle the washer's running and surge wattage demands. Choosing a properly sized PPS will allow you to finish all your laundry off-grid. 

Tips: If you are really unsure about what size power station to buy for your washing machine, the easiest way is to leave a message on the portable power station brand's website or send an email for consultation.
