What is the difference between a power bank and power station?
A power bank is a small, portable device that's used to charge electronic products like smartphones, laptops and more. On the other hand, a power station can store huge amounts of energy to power electrical appliances like mini-fridges, microwaves and more. Can a portable power station be your home backup? The answer, surprisingly, is yes.
What is a power bank & how does it work?
A power bank is vastly different from a power station. There's a significant difference in the amount of energy they can store, the cost of owning them and the devices they can charge. A power bank is a small, portable device that's used to charge electronic products like smartphones, laptops and more.
How is electricity stored in a portable power station measured?
The electricity stored in a portable power station is measured in kilowatt-hours (kWh), which is described as one watt of electricity used for one hour. Capacity is one of the significant aspects when choosing a suitable power station, and it is directly related to power output.
Can a power bank charge a phone?
A power bank connected through a type-c data cable to a smartphone can provide about 30,000 mAh of power and a 12V portable power supply. Compared to portable power stations, power banks cannot charge large appliances. Power banks often use a mini USB for charging and a full-size USB for discharging.
What type of battery does a power bank use?
The standard battery types found in power banks are lithium-ion and lithium-polymer. The built-in battery charges through an external power supply like a wall socket. It then stores the energy in chemical form and sends electrical energy to the device when needed through an output port.
What is the best power bank for kids?
Editor’s Note: On March 15, 2025, we updated this guide by adding our favorite power bank for kids, the Nimble CHAMP Pro Portable Charger to our line-up. We’ve been using the Nestout 15000mAh Outdoor Battery ($60) for over a year for work and play, and it has more than earned the top spot on this list.
