The popularity of power banks continues to grow as modern gadgets are equipped with high-powered cameras and numerous useful apps. As a result, battery depletion occurs at an accelerated pace. If accessing a power source is not an option, using an external battery becomes the only solution.
Criteria for Choosing a Portable Charger
When considering which Power Bank to buy, it’s essential to compare the most important parameters of available models. These typically include:
- Capacity,
- Size,
- Charging current,
- Casing material,
- Functionality.
By studying the manufacturer’s information, you can likely select a good quality model.
Capacity
The importance of this parameter cannot be overstated. However, a higher capacity does not always guarantee better quality. A good rule of thumb is that the capacity of the power bank should be 2-3 times greater than that of your device’s battery. Purchasing a bulky, high-capacity device may not always be practical. Some lesser-known brands claim capacities of 20,000, 30,000, or even 50,000 mAh, but the accuracy of these claims should be questioned.
Size
When thinking about buying a Power Bank, consider how convenient it will be to use and store. A higher-capacity model can weigh up to half a kilogram, which makes it impractical to carry in a jacket or pants pocket for long periods. In such cases, a backpack would be necessary. The optimal choice would be a device weighing no more than 250 grams.
Charging Current
The charging current determines how fast your electronic device will charge. For smartphone owners, it’s best to choose a power bank with a current rating of 1 A. Tablet users should opt for a higher current, around 1.5–2 A. When purchasing a charger, check the specifications to ensure the charging current of the power bank matches that of your device. Manufacturers typically indicate this near the USB port.
Casing
Before buying a Power Bank, make sure it has sufficient mechanical strength. An aluminum casing can be a good alternative to plastic. Some models are even available in metal cases with protective rubber coverings.
Functionality
Additional features include the number of ports, such as 2 or even 3. Having multiple outputs makes the device more convenient to use. A built-in LED flashlight can also be handy for quickly locating the charging port. A digital indicator showing the remaining charge is another useful feature.
By considering all these factors, you can purchase a quality Power Bank at an affordable price.
