Portable power stations (PPS) offer a reliable and versatile energy solution for various scenarios, from camping and caravanning to home backup and off-grid living. Choosing the right size is essential to ensure your PPS meets your energy requirements, whether for small gadgets or heavy-duty appliances.
This guide explores selecting the perfect PPS based on capacity, portability, input/output options, your particular usage scenario, and the benefits of pairing it with solar power for efficiency and adaptability. Let’s get started.
The Importance of Choosing the Right Size Portable Power Station
Selecting the correct size for your portable power station (PPS) is critical to ensuring that what you buy meets your energy needs. Here are some of the important benefits of choosing the right size.
Versatility in Different Applications
When you have an appropriate-sized PPS, you can use it for multiple scenarios. For instance, choosing a size suitable for caravanning means you can also use it at home to run your essential appliances during an electrical outage. In fact, with the right size of PPS, you can run any appliance that you have.
Alternatively, start with a PPS suitable for home backup for essential appliances, but choose an expandable model so you can eventually run your entire home during blackouts or as an off-grid energy solution. For instance, the EcoFlow DELTA Pro 3 starts at 4000W but is expandable up to 12kWh.
Reduces Grid Electricity Use
Choosing a large enough solar-powered PPS to run household appliances can significantly reduce your grid electricity use, helping you be more self-sufficient and reduce your carbon footprint.
Financial Benefits
Choosing a model that can meet your energy needs, whether just to run some of your appliances or all, can save tons of money on your electricity bills. In fact, with a large enough solar array and enough batteries, you may never have to pay an electricity bill again.
After the return on your investment (ROI), when the savings on your bill pay for your solar system’s purchase, your energy will be free for at least 20 years. This is a huge financial benefit.
Increases Work Efficiency
When you have the correct size PPS, it offers a reliable energy source and reduces inefficiencies. For instance, if yours is too small, you will constantly need to monitor and manage your power levels and pick and choose which appliances you can run depending on how much energy is being drawn.
If you have the right size, you can simultaneously use some or all of your appliances whenever you need them. It enhances convenience and improves workflow efficiency at home, in the shop, or in your home office.
How Do You Choose the Right Size Portable Power Station?
Decide How You Want To Use It
The most important factor in deciding what size you need is how you plan to use it. Let’s examine some examples:
For Home
For use in the home, you’ll want a larger PPS. But do you need it for essential appliances during a power outage or a whole-home solution? Either way, the EcoFlow DELTA Pro 3 is perfect. Starting at 4000W, it will run all your essential appliances. You can recharge it with solar panels and add batteries to expand it up to 12kW for a perfect whole-home backup solution.
For Caravans
You will want a relatively large capacity for use in caravans, but not so large that it becomes too cumbersome. The EcoFlow DELTA 3 is perfect, starting at 1024Wh and expandable to 5kWh; it will run any RV appliance you may have. Bring your portable solar panels, and you can stay off-grid for as long as you want.
For Camping
For camping, especially in tents, you’ll want a smaller, more portable PPS. The EcoFlow RIVER 2 Max has 512Wh but is compact and lightweight enough to pack in a backpack for hiking or bush camping.
Or, if the EcoFlow RIVER 2 Max doesn’t have enough power for you but you still need portability, the EcoFlow RIVER 2 Pro Portable Power Station has 768Wh of capacity, the perfect balance between capacity and portability.
Capacity
Capacity is critical since you must have enough to run your essential appliances and devices. For instance, a simple power bank would be sufficient if you only need to charge your phone once. But most of us need more power. Fortunately, EcoFlow Portable Power Stations come in a wide range of capacities, from small, lightweight models that you can put in a backpack to powerhouses that will run even the largest off-grid homes.
Another factor to consider is the ability to recharge with solar. Solar panels generate clean, renewable energy via the photovoltaic effect, producing no greenhouse gases, and can recharge your PPS in just a few hours. It enhances your usable capacity because solar panels can recharge your PPS daily.
Another factor is that you cannot add anything to your system if you buy exactly what you need. As a rule of thumb, choose a capacity about 25% larger than you need. Alternatively, look for models that easily expand your capacity with an additional storage battery to meet your needs as they grow.
One final thing to consider regarding capacity is that you should always buy a larger PPS than you need. One reason is that depending on how and where you use it, your PPS may not always be efficient enough to meet your needs.
Portability
Portability is critical if you plan to travel, camp, or move your PPS between your home and shop. But how portable do you need it to be? Do you need it to fit in a backpack? If so, portability is everything; you must choose a small-capacity model.
Otherwise, you can use a larger capacity model if you need to move it in and out of a vehicle or around your home and property. When looking at larger models, always consider whether they have sturdy carry handles or wheels to help move them around more easily.
Additional Options
Always look at all the other options available as well. For instance, can it be recharged with AC wall plugs, DC car plugs, and solar power? For versatile output options, look for ones that also run 12V DC appliances or offer USB and USB-C options to run various devices without needing so many adapters. Finally, check if it comes with a smartphone app to monitor your batteries and help optimise their lifespan.
How Do I Calculate What Size Portable Power Station I Need?
Determining what size PPS you will need is easy. You just need to calculate your kWh of energy usage. To do this, list every appliance you need to run with it. It might be every electrical device in your caravan or camping set-up, essential household appliances that need to run during an electrical outage, tools you need to run in a shop, or everything in your home for a whole-home backup or off-grid solution.
Once you have your list, find the watts or kilowatts, where 1000W = 1kW of energy each device or appliance uses. If you find energy ratings in Amps, you can convert between units using Watts = Amps x Volts.
Next, multiply those watts by the number of hours the device needs to run. For instance, if your coffee maker uses 900W but you only need to run it for 30 minutes, then 900W x 0.5h = 450Wh. On the other hand, if you have a 1500W heater that you run for 6 hours, your usage is 1500W x 6h = 9000Wh.
Once you have all your watt-hours (or kilowatt-hours), add them up to get your minimum capacity. As a rule of thumb, add 25% to that to ensure you always have enough.
Final Thoughts
Choosing the right portable power station is vital for efficiently meeting your energy needs, whether camping, travelling, or preparing for home emergencies. From calculating your energy consumption to evaluating portability and input/output options, the right PPS can enhance energy independence and reduce costs.
