Power Banks

Power banks, also called portable chargers or external batteries, are portable power packs designed to store electrical energy to power multiple devices on the go. These powerhouses are significant in scenarios, especially when travelling, where immediate power (wall outlets) is not available. A power bank typically consists of input and output ports for charging a great range of devices and itself. Power banks store energy within integral rechargeable batteries (usually lithium-ion or lithium-polymer). These portable chargers come in varied capacities, depending on the model and intended applications. The capacity of a power bank is measured in milliampere hours (mAh), which indicates how much power the battery can hold. Additionally, power banks are often incorporated with LED indicator lights to display the charging status and remaining battery’s capacity. 

Popular Types of Power Banks

Power banks come in various types based on their capacities, charging configurations, and designs. Some of the most common power bank types include:

• Universal Power Banks – These are the most common and standard power banks, compatible with various devices, such as smartphones, tablets, and laptops.
• Solar Power Banks – These power packs house solar panels to charge themselves using solar energy, making them ideal for outdoor activities.
• High-Capacity Power Banks – These power banks have a higher capacity than standard power banks, allowing them to charge devices multiple times.
• Low-Capacity Power Banks – These are smaller and have a lower capacity, making them more portable and ideal for emergencies.
• Wireless Power Banks – They use wireless charging technology to charge devices, eliminating the need for cables and wires.
• Quick Charge Power Banks – Quick charge power banks support fast charging technologies like Qualcomm Quick Charge or USB Power Delivery. These power banks, as the name suggests, can charge compatible devices much faster than standard power banks.
• Multi-Port Power Banks – These portable chargers feature multiple USB ports designed to charge multiple devices simultaneously. They are convenient for sharing power with friends or charging multiple devices on the go.
