Before you shop for a portable power station, there are several things you need to consider:
Price: Portable power stations can be expensive, but discounts and sales are common. If you can wait, you may be able to get a better deal on your chosen power station.
Capacity: Determine how much power you need by considering the devices you want to run and how long you need to run them. Manufacturers often list estimated run times for specific devices, but it’s important to calculate the actual power usage of your devices.
Portability: While advertised as portable, some power stations can be heavy and difficult to carry long distances. Larger capacity stations may have wheels and handles for easier transportation, but keep in mind the weight when considering portability.
Battery Technology: Most portable power stations use lithium-ion batteries, with different variations like lithium nickel manganese cobalt oxide or lithium iron phosphate. Each type has its own advantages and disadvantages in terms of safety, longevity, and energy density.
Ports: Check the types of ports and charging standards supported by the power station to make sure it meets your needs. Some stations may have USB-C ports, car ports, and inputs for solar panels, so be sure to review the specifications before purchasing.
Charging Speed: Consider how quickly the power station can recharge from different sources, especially if you plan to use solar panels or a car battery for charging. Some stations support fast-charging from multiple inputs.
Heat and Noise: Batteries generate heat when charging, which can lead to noisy fans in the power station. Be aware of potential heat and noise issues, especially if using the station in an enclosed space.
Maximum Output: Ensure the power station can deliver the wattage required for your devices, especially if using power tools or appliances that require high wattage. Check the maximum output and surge capabilities of the station to meet your power needs.
UPS and EPS: Some power stations can act as uninterruptible power supplies (UPS), switching to battery power instantly in case of a power outage. Other stations may act as emergency power supplies (EPS), with a slightly longer switch time during blackouts.
Consider these factors before purchasing a portable power station to ensure it meets your power needs and expectations.
