Choosing the Right Power Bank for Your Needs

Various power banks and charging cables

Selecting the right power bank is not just about picking the one with the highest capacity. It’s about finding a perfect balance between capacity, portability, and compatibility with your devices. A quality power bank should be able to power your devices at their fastest charging speeds, offering an uninterrupted mobile experience.

Consider where and how frequently you use your devices. If you are often in places without wall outlets, like during travel or at outdoor events, you need a power bank with enough capacity to charge your laptop or other high-capacity devices. Advanced power banks even come equipped with fast-charging USB-C PD ports, ideal for high-capacity charging requirements.

Determining Capacity Requirements

Understanding that the actual usable capacity of a power bank is approximately 2/3 of the rated capacity due to energy loss and voltage conversion is one of the key factors during the selection process. Equally vital is to consider the battery size of your device(s) and the number of charges you need before recharging the power bank.

For instance, a 10,000mAh power bank, with about 6,660mAh actual capacity, can charge most new smartphones roughly 1.5 times. In contrast, a larger 27,000mAh power bank, with around 18,000mAh actual capacity, is suitable for charging multiple devices or for week-long usage without recharging. Online guides that match device battery sizes with power bank capacities can provide personalized recommendations.

Port Selection: USB-A vs. USB-C Ports

The type and number of ports on a power bank can significantly impact its versatility. Having multiple port types, such as a USB A port and a USB C port, enables the charging of a wide range of devices concurrently. This feature is particularly useful in scenarios like group travel or events, where several devices may need to charge at the same time.

Choosing a power bank with at least two USB charging ports, including USB-A and USB-C, means you can charge a phone and an additional device simultaneously. Power banks with varied charging outputs can accommodate different devices, such as laptops or handheld gaming consoles, by providing appropriate charging rates. Verifying the compatibility of the power bank ports with your devices is paramount.

The Need for Speed: Fast Charging USB-C PD

Fast charging has become a standard feature in many power banks, offering the convenience of quick top-ups for your devices. To reap these benefits, it is necessary for your smartphone to support the fast charge protocol offered by the power bank.Technologies like Power Delivery (PD) can charge compatible smartphones up to 55-60% in about half an hour.

In the selection of a power bank for fast charging, high amperage outputs and inputs should be taken into account. These enable faster device charging and quicker recharging of the power bank itself. iWALK places a premium on power banks that offer USB-C PD charging capabilities and high output power, ensuring both speed and compliance with safety and transport regulations such as TSA guidelines.
