How expensive are portable power stations?

Portable power stations can be very expensive, but discounts, sales, and deals are common. If you can afford to wait, you can likely get your chosen power station for less than the listed MSRP.

What capacity do I need?

Figure out how much power you need. The capacity is listed in watt-hours (Wh) or sometimes kilowatt-hours (kWh). If you think about the devices you want to run and how long you need to run them, you can start to calculate the capacity you need. Manufacturers will often display stuff like 12 hours of TV or 30 minutes of electric chain saw use, but not all TVs draw the same amount of power. You must calculate how much the gadgets you own actually use.

How portable are portable power stations?

The term “portable” is stretching it sometimes. Batteries are heavy. The larger-capacity power stations are typically on wheels and have telescopic handles, and they are still tough to cart around. If you’re looking for something you can actually carry on foot for a distance, you may need to temper your expectations on capacity.

What can you run on a portable power station?

All portable power stations can charge up small gadgets like phones and laptops or be used to power lighting. Most can handle small appliances like mini-fridges or TVs. If you want to use power tools, an AC unit, or in the UK, a kettle, you need to be able to draw thousands of watts. Power stations all state the maximum output, but they often have a surge function that enables them to go higher for a short period. Sometimes, they give it a silly name. For example, Zendure calls this “AmpUp,” and EcoFlow calls it “X-Boost.” Make sure your chosen power station can handle the wattage you need.

How do I charge a portable power station?

All portable power stations can be charged from a wall outlet and should come with a charging cable. Some power stations can also be charged via a car port from your vehicle or a solar port from solar panels. Make sure you check that the ports you want are available and necessary cables are included.

How long does a portable power station take to charge?

Large-capacity power stations can take a long time to recharge. Be sure you understand how quickly your chosen power station can charge from wall power and other sources if you plan to use solar panels, a vehicle battery, or another power source for top-ups. Some power stations enable you to fast-charge from two or more inputs.

What ports should I look for in a portable power station?

While you will find certain ports across the board with portable power stations, from AC outlets to USB-A, it is crucial to check the maximum charging rate and supported charging standards to avoid disappointment. You might find USB-C ports, car ports, barrel ports, and maybe inputs for solar, but assume nothing. Check the specs before you buy.

How many years do portable power stations last?

Power stations typically last between 3 and 10 years, but can last longer, depending on how they are used and maintained. It’s important not to let them completely discharge too often or leave them empty for extended periods. Usually, the manufacturer will provide an estimate of how many charge cycles you can expect to get before the performance starts to degrade. Warranties typically range from two to five years, but make sure you retain the guarantee and proof of purchase.

What battery types are most commonly used in portable power stations?

There are various battery technologies, but the main ones used in portable power stations today are types of lithium-ion (Li-ion) batteries, often lithium nickel manganese cobalt oxide (Li-NMC) or lithium iron phosphate (LiFePO4 or LFP). The latter is safer (less prone to combustion) and tends to last longer (more cycles) before it starts to degrade. Overheating can be an issue for Li-NMC batteries, and they degrade faster but have a higher energy density. Zendure also offers semi-solid-state batteries in its top-of-the-line SuperBase listed above, which it promises are more stable and resilient, therefore safer, and have a higher energy density.

Can you use a portable power station as a UPS?

Some power stations can act as an uninterruptible power supply (UPS); others are classed as an emergency power supply (EPS). If you have your power station plugged into wall power and then devices plugged into it, they will work from wall power, but if there is a power outage, a UPS will switch to battery power instantly (around 10 milliseconds). An EPS will also switch when there’s a blackout but may take a bit longer (30 milliseconds or so).

What is the difference between a power bank and a portable power station?

Size is the main difference between the best power banks and the best portable power stations. Power banks are typically compact with small capacities designed to charge smartphones and other small gadgets. Power stations have far larger capacities and can potentially run small appliances and larger gadgets.
