Portable chargers, also known as power banks, are lifesavers to keep electronic devices powered. They store electrical power, which can be used to charge your smartphone, tablet, or laptop, especially when you’re far from a reliable power source. Essentially, a power bank can help you keep your devices running longer when you’re on the go. Available in various capacities and sizes, these handy accessories are indispensable for travelers, commuters, and anyone who spends a lot of time away from home. Here are some of the main benefits of power banks and why you might consider getting one.
What are power banks
Equipped with built-in batteries designed to store electrical energy, power banks allow you to easily charge electronic devices such as smartphones, tablets, and cameras, especially when access to a power outlet is unavailable. These chargers typically feature one or more USB ports to connect with corresponding cables, so you can replenish your devices’ batteries on the go.
Types of power banks
Power banks come in various types, primarily categorized by capacity and adapter types.
Capacity and size
Capacity is a critical aspect of a power bank. Measured in milliampere hours (mAh), it determines both the number of charges your device can receive and the types of devices it can power. Higher-capacity models store more power, translating to more charges. They can also accommodate a wider range of devices. On the other hand, lower capacity models offer fewer charges. However, they are often more compact and lightweight, making them ideal for everyday use and travel where space and weight are concerns.
- Up to 6000 mAh: These are the most compact power banks. Use them for an emergency charge or daily use for primarily smartphones.
- 6001 – 12499 mAh: A mid-range capacity that is perfect for those who need multiple charges for one or more devices.
- Over 12500 mAh: Designed for high-demand users who might need to charge multiple devices multiple times or provide substantial power to high-capacity devices like tablets or laptops.
Adapter types
Power banks are equipped with various adapter types to connect to a multitude of devices. This ensures compatibility across a wide range of electronic devices. Make sure to pick a power bank that is compatible with the device you would like to charge. Here are the most common connectors found in power banks:
- Lightning: Predominantly used by Apple devices, the Lightning connector is essential for iPhone, iPad, and AirPods users.
- USB-C: This connector has become the industry standard for new electronics, including new iPhones, tablets, and even some laptops, offering faster charging capabilities.
- Micro USB: Although being gradually phased out, the Micro USB connector is still widely found in many older smartphones, certain cameras, and other portable devices.
- USB (Universal): Traditional USB ports allow versatile connections with standard USB cables. They are compatible with a broad array of devices.
Benefits of power banks
Being able to stay powered up while on the move is more important than ever. From ensuring uninterrupted connectivity to enhancing productivity on-the-go, power banks have become indispensable companions. Here are some of the reasons why you might consider getting one:
1. Uninterrupted connectivity
One of the most significant benefits of power banks is uninterrupted connectivity. Whether it’s keeping in touch with loved ones, handling business communications, or accessing important online resources, power banks keep your devices charged, wherever you are. They provide peace of mind that you won’t be left without power in critical moments.
2. Enhanced productivity
With a power bank, you can extend the usage time of your devices, allowing you to stay productive even when you’re away from power sources. Whether you need to respond to emails, work on documents, or stay entertained during travel, a power bank ensures you can keep going without interruption. You can stay productive or entertained on-the-go without worrying about battery life.
3. Convenience in remote locations
For outdoor enthusiasts or those traveling to remote locations, power banks offer the convenience of keeping devices charged without access to traditional power sources. If you’re camping in the wilderness or exploring off-grid destinations, a reliable power bank ensures you can capture memories, navigate trails, and stay connected.
How to choose the right power bank
When selecting a power bank, take into account your lifestyle and device requirements. Here are a few features to consider to ensure you choose one that suits your needs:
Capacity and compatibility
First and foremost, check the capacity of the power bank. This determines how many charges you can get for your devices before recharging the power bank itself. It’s also important to ensure the power bank is compatible with your devices. Look for one that supports the specific adapters your devices require (such as USB-C, Lightning, or Micro USB).
Portability and design
Consider the size and weight of the power bank. If you need a charger that’s easy to carry on daily commutes, a compact and lightweight model would be ideal. However, if you require more power for long trips or multiple devices, a larger and higher-capacity power bank might be necessary even though it’s a bit heavier.
Safety features
Safety should never be overlooked. A quality power bank should have built-in safety features such as overcharge protection, temperature control, and short-circuit prevention. These help protect both the power bank and your devices from damage.
Charging speed and efficiency
If quick charging is a priority, look for a power bank that supports fast charging technologies compatible with your devices. The output power of the power bank plays a crucial role in determining how rapidly it can charge your device. Also, consider the efficiency of the power bank, which impacts how much of the stored energy is actually used to charge your devices instead of being lost as heat.
Additional features
Some power banks come with extra features that might be beneficial depending on your needs. These can include multiple ports to charge more than one device at a time, built-in cables, or even wireless charging capabilities. Evaluate these features based on how you plan to use the power bank.
