What is a Power Bank?
A power bank is a portable charger that serves as an external battery for mobile devices such as smartphones, tablets, and laptops. It has become an essential accessory in today’s world where people rely heavily on their mobile devices for communication, entertainment, and work. With a power bank, users can charge their devices on-the-go without the need for a wall socket.
The battery capacity of a power bank is measured in mAh (milliampere-hour) and can range from as low as 2,000mAh to as high as 50,000mAh or more. The higher the capacity, the more charging cycles the power bank can provide.
Other popular features of power banks include USB-A and USB-C ports, power delivery, quick charge, pass-through charging, dual input ports, built-in cables, and physical size. With a power bank, users can always have extra power for their mobile devices, making it an ideal choice for everyday carry and outdoor gear.
What Are the Benefits of Owning a High-Capacity Power Bank?
A high-capacity power bank is an essential accessory for anyone who needs longer battery life for their mobile devices. With a larger battery capacity of up to 20000mAh, these power banks can provide multiple charges for your phone or tablet, making them a reliable source of power when you’re out and about.
High-capacity power banks also offer convenience and ease of use. They’re compact in size, making them easy to carry in your bag or pocket, and come in various designs to suit different needs. Whether you’re on a camping trip, traveling, or simply running errands, a power bank can keep your phone charged throughout the day.
When choosing a high-capacity power bank, it’s important to consider the maximum output and charging speeds. This will determine how quickly your devices will charge and how many devices you can charge at once. Power banks with USB-C ports and Power Delivery technology provide faster charging for compatible devices, while those with multiple USB-A ports and built-in cables allow you to charge multiple devices simultaneously.
Owning a high-capacity power bank is a convenient and practical solution for anyone who wants to ensure their mobile devices stay charged longer. By considering key factors such as maximum output and charging speeds, you can choose the right power bank to suit your needs.
What to consider when looking for the best 20000mah power banks?
Battery Capacity
When choosing a power bank, one of the most important factors to consider is battery capacity. Battery capacity is measured in milliampere-hours (mAh) and determines how much power the power bank can store. The recommended minimum capacity for a portable power bank is 10,000mAh, which can provide around 2-3 charges for an average smartphone.
The number of charges available depends on factors such as the device’s battery size, the charging cycles of the power bank, and the device’s power needs. It’s important to choose a power bank with enough capacity to meet your device’s needs, while also balancing physical size and weight.
The physical size and weight of a power bank can vary widely depending on its capacity. For example, a 20,000mAh power bank will be larger and heavier than a 10,000mAh power bank. When choosing a power bank, consider your usage scenario – if you’ll be using it for outdoor activities like camping trips, a larger power bank might be necessary. However, if you’ll be carrying it in your everyday carry, a smaller and lighter power bank is recommended.
It’s essential to choose a power bank with sufficient capacity to meet your device needs, while also being mindful of physical size and weight.
USB Ports & Outputs
High-capacity power banks come with a variety of USB ports and outputs. The most common ones include USB-C ports, USB-A ports, and pass-through charging capabilities.
USB-C ports are becoming more popular as they offer faster charging speeds and the ability to charge larger devices like laptops. They also allow for two-way charging, meaning your power bank can charge your device and your device can charge the power bank simultaneously.
USB-A ports are the standard ports found on most devices and offer charging speeds that are slower compared to USB-C. However, they are still useful for charging smartphones and other smaller devices.
Pass-through charging allows you to charge your power bank while it is charging another device. This feature is useful if you have limited outlets.
Different types of USB ports and outputs affect the charging speed of your devices. USB-C ports offer faster charging speeds, while USB-A ports have slower charging speeds. The more versatile the USB port configuration of a power bank, the easier it is to charge different types of devices.
Some of the power banks that offer the most versatile and useful USB port configurations include Anker PowerCore+ 26800mAh, Aukey Power Bank 20000mAh, and RAVPower 10000mAh Portable Charger.
Built-in Cables & Connectors
When it comes to power banks, having built-in cables and connectors can be a game-changer for those who are always on the go. Among the popular power banks in the market, some come with built-in cables, such as USB-C, USB-A, Lightning, and Thunderbolt.
An example of a power bank with built-in cables is the Anker PowerCore Fusion 5000, which comes with a USB-A cable for charging phones and other small devices. Another example is the RAVPower USB-C Power Bank, which comes with both USB-C and USB-A cable for charging a variety of devices.
Built-in connectors are convenient since you don’t need to bring any additional cables with you for charging. Cables come in different types, and not all connectors are compatible with every device. USB-C and Lightning connectors are common for charging Apple devices, while Thunderbolt connectors are typically used for high-speed data transfer.
If you want to ensure compatibility with your devices, make sure to purchase a power bank with the proper built-in cables and connectors. Built-in cables make charging more straightforward and make power banks a must-have for people on-the-go.
Size & Weight
When it comes to high-capacity power banks, such as the 20000mAh ones, there is a range of sizes and weights available in the market. On average, these power banks measure around 6-7 inches in length, 2-3 inches in width, and 1 inch in thickness.
In terms of weight, they usually weigh 12-18 ounces, which makes them a bit heavier compared to the lower-capacity power banks. However, they are still relatively compact and easy to carry around, making them suitable for everyday use or outdoor trips like camping or hiking.
It’s worth noting that some power banks come in larger sizes and weights, which can accommodate additional features such as multiple charging ports, digital displays, or even solar panels for charging on the go. However, if you’re looking for a power bank with a slim design and lightweight, there are plenty of options available in the market.
The size and weight of 20000mAh power banks are generally manageable and don’t take up too much space in your bag or pocket, making them ideal for keeping your mobile devices charged on the go.
Charging Speeds & Quick Charge Technology
A 20000mAh power bank is capable of charging most smartphones up to 4-6 times before needing a recharge itself. However, the charging speed also depends on the power bank’s output and the device’s input requirements.
This is where Quick Charge technology comes in handy. It is a Qualcomm fast-charging protocol that enables certain smartphones to recharge up to 50% in just 5 minutes. That means you can get a significant amount of power in a short amount of time.
While power banks with Quick Charge technology may cost a bit more, they offer faster charging times, making them an excellent investment for those who are always on the go. However, it’s important to ensure that the output of the power bank meets or exceeds the input of the device to ensure the fastest charging possible.
A 20000mAh power bank with Quick Charge technology is an excellent option for anyone looking for a fast and reliable charging solution for their smartphones or other compatible devices.
Digital Display or Indicators
Digital display or indicators are an essential feature in high-capacity power banks, such as 20000mAh power banks. These displays provide real-time updates on the power level of the device, allowing users to monitor how much power is left and when it’s time to recharge the power bank.
Having a digital display in a power bank can be incredibly helpful, especially when using multiple devices simultaneously. By monitoring power levels, users can prioritize power distribution accordingly and prevent any devices from running out of juice unexpectedly. It is also useful during long trips or camping trips where power sources may be scarce.
There are various types of power bank displays available in the market, including LED lights, LCD screens, and OLED screens. LED lights are the most common and are usually located on the side of the device. They display the power level through a series of dots or bars that light up progressively as the device charges.
LCD screens provide more detailed information, such as charging status, battery level, and remaining charging time. OLED screens go a step further by displaying the charging percentage and an estimation of how much power is left in the battery.
Durability & Protection Features
When selecting a power bank, durability and protection features are crucial considerations. Power banks with shock-resistance and waterproofing capabilities provide added protection from accidental drops or exposure to water that can damage the internal components.
In terms of safety features, overcharge and short-circuit protection are critical. Overcharge protection prevents the battery from overcharging beyond its capacity, which can damage the battery and the device it’s charging. Short-circuit protection automatically shuts off power when a short circuit is detected, protecting the power bank and the connected device from damage.
Power banks can be constructed from various materials that contribute to their durability and protection. Aluminum or alloy casings add ruggedness to the power bank. Such power banks may also feature reinforced corners and rubberized exteriors to absorb shock and prevent damage.
Pass-through charging is another useful feature to consider, particularly for outdoor activities or everyday carry. This feature enables the power bank to charge while simultaneously charging other devices. It ensures that the power bank remains charged and can provide an extra boost of power when needed.
When selecting a power bank, prioritize models with shock-resistance, waterproofing, and safety features that protect against overcharge and short-circuiting. The materials used in the construction of the power bank should also enhance its durability, and pass-through charging is a handy additional feature to consider.
