Before we delve into the specifics, let's start by understanding what a power bank actually is. Essentially, a power bank is a portable charger that stores electrical energy and allows you to recharge your electronic devices on the go. With a power bank in your bag or pocket, you can say goodbye to the anxiety of a drained battery.
The battery is the heart of the power bank, responsible for storing the electrical energy. The circuitry acts as the brain, regulating the flow of energy and protecting your devices from overcharging or overheating. The charging ports, often USB or USB-C, are where you connect your devices.
Output power, measured in watts (W), tells you how quickly the power bank can charge your device: 5W–10W – Basic charging speed, which works fine for most devices. 18W–30W – Faster charging, ideal for newer smartphones and tablets. 45W or higher – Good for charging laptops and other high-power devices.
With a power bank in your bag or pocket, you can say goodbye to the anxiety of a drained battery. Power banks consist of a battery, circuitry, and one or more charging ports. The battery is the heart of the power bank, responsible for storing the electrical energy.
Nearly every rechargeable power bank you can buy (and most portable devices) contain a lithium-ion battery. These beat other current battery types in terms of size-to-charge capacity, and have even increased in energy density by eight fold in the past 14 years.
Although its 3,350mAH battery capacity can fully charge most phones with no problems, it is not made for more powerful devices like iPads or tablets. MyCharge Adventure Mini is the smallest power bank in our review. Despite only weighing 0.2lbs, it can fully charge most phones on the market with its 3,350mAH battery capacity.
