A portable power station works like a large power bank to supply electricity. It can be used for several purposes, like charging laptops and powering outdoor lights during emergencies or when camping. One may even be able to power up larger appliances like fridges and air conditioners, depending on the device’s power output. Those looking to buy portable power stations should learn about their costs and working mechanisms to make more informed decisions.

Portable power station prices
The cost varies based on several factors, such as the power station’s capacity, output options, brand reputation, and features.

• Budget models, also known as entry-level or small-capacity portable power stations, generally cost between $110 and $300.

Remember, the average cost range for portable power stations can change depending on market demand and any ongoing power crisis situations.

Tips to buy portable power stations
Before choosing a model, one should consider its power capacity, battery type, ports, charging speed, and features.

Pick the right capacity and power output
A power station’s capacity refers to how much energy it can store for future use and is measured in watt-hours (Wh) or amp-hours (Ah). The power output, on the other hand, is the amount of electricity or power it can deliver at any given time whenever needed. This is measured in watts (W).

The device’s power capacity and output are the two most critical factors when deciding which power station to purchase. When making this choice, one must consider which devices they will charge or power and their overall energy requirements. Getting models with a lower capacity and modest output values makes sense if someone needs to charge laptops or smartphones.

Check the battery type and lifespan
Generally, portable power stations are powered by LiFePO4 (Lithium Iron Phosphate) or Lithium-ion batteries for sustainable energy. Of these, the LiFePO4 alternative is better as it comes with a greater lifespan and durability (five to ten years, compared to the two to three-year span of lithium-ion battery-powered models). They also offer more usage cycles (2500 to 3500, compared to 500 to 1000).

LiFePO4-powered portable power stations are more stable and resistant to overheating than lithium-ion ones. As a result, the risk of fires is significantly lower. Possibly, the only downside to LiFePO4-powered power stations is that they are bulkier than their lithium-ion-powered counterparts.

Look at the power output ports
Another major dealbreaker when it comes to portable power station purchases is the number and type of power output ports. Some critical output ports to have in a portable power station are:

• Car charger ports
  Also called the 12V accessory outlets, these ports provide the power to charge and operate 12V devices such as modems and routers.
• Anderson Power Pole
  These are designed to link high-current applications. They are commonly used to jump-start vehicles and ham radios.
• Standard power outlets
  These electrical sockets provide alternating current (AC) power to commercial devices and household appliances. Select portable power stations come with an Uninterruptible Power Supply (UPS) feature through their AC outlets. This feature instantly lets users switch their power source from a wall outlet to a portable power station.
• USB charging ports
  These standardized connectors can be used for charging as well as data transfer in electronic devices. USB ports with the USB PD (power delivery) specification allow users to quickly power up their handheld devices and even charge their laptops.

Check the charging speed
How quickly a portable power station tops up any connected device depends on various factors. For instance, the battery capacity and power output influence how effectively and smoothly the power is delivered to the connected device. Manufacturers often provide the time their portable power stations will take to charge any units fully through standard AC outlets.

If a power station has a capacity of 1000Wh and the charger delivers 200W, the estimated charging time is approximately five hours (derived by dividing 1000 by 200). Charging times vary based on the charger’s specifications and the battery technology. Apart from this, using solar panels or car chargers results in longer charging times due to lower power outputs.

Consulting the manufacturer’s customer service department is a great way to get clear information about their power station’s speed and similar statistics.

Look for additional features
Besides doing the bare minimum of powering up devices, some portable power stations have other features that increase their value.

• Display screens to provide users with real-time information on battery usage and status
• Handles or wheels to make transportation easier when moving a portable power station
• The ability to link multiple power stations for increased power dispensing
• Warranties to cover the costs in case the power station breaks down or malfunctions
• Wireless charging
