The Anker Laptop Power Bank is a high-capacity portable charger with a substantial 25,000mAh battery, making it ideal for those who need to keep multiple devices charged on the go. It features three USB-C ports, each capable of delivering up to 100W, allowing simultaneous charging of devices such as a MacBook and smartphones. This power bank is particularly useful for travelers or individuals who use multiple devices daily, as it complies with airline carry-on regulations for batteries under 100Wh and includes built-in and retractable cables for convenience.

Buying Guide for the Best Portable Power Banks

Choosing the right portable power bank can make a big difference in ensuring your devices stay charged while you're on the go. It's important to consider several key specifications to find the best fit for your needs. Understanding these specs will help you make an informed decision and ensure that the power bank you choose meets your requirements.
Capacity (mAh)Capacity, measured in milliampere-hours (mAh), indicates how much charge a power bank can store. This is crucial because it determines how many times you can charge your devices. Power banks with lower capacity (up to 5,000 mAh) are lightweight and suitable for occasional use, like giving your phone a quick boost. Mid-range capacity (5,000 to 10,000 mAh) is good for daily use and can charge a smartphone 2-3 times. High capacity (10,000 mAh and above) is ideal for heavy users or for charging multiple devices, such as tablets and laptops. Choose a capacity based on how often you need to charge your devices and how many devices you typically carry.
Output Power (Wattage)Output power, measured in watts (W), determines how quickly a power bank can charge your devices. Higher wattage means faster charging. Standard power banks offer 5W to 10W, which is sufficient for most smartphones. For faster charging, look for power banks with 18W or higher, which support fast charging technologies like Quick Charge or Power Delivery. If you need to charge larger devices like tablets or laptops, opt for power banks with 30W or more. Consider your device's charging requirements and how quickly you need them charged when choosing the output power.
Number of PortsThe number of ports on a power bank determines how many devices you can charge simultaneously. Single-port power banks are compact and suitable for users who only need to charge one device at a time. Dual-port power banks allow you to charge two devices simultaneously, which is convenient for users with multiple devices. Some power banks offer three or more ports, ideal for families or users who need to charge several devices at once. Think about how many devices you typically need to charge at the same time to decide on the number of ports.
Port TypesPort types on a power bank include USB-A, USB-C, and sometimes micro-USB. USB-A is the most common and compatible with many devices. USB-C is becoming more popular due to its faster charging capabilities and reversible design. Some power banks also have micro-USB ports, mainly for charging the power bank itself. If you have newer devices, look for power banks with USB-C ports for faster and more efficient charging. Ensure the power bank has the right port types for your devices to avoid compatibility issues.
Size and WeightSize and weight are important factors, especially if you plan to carry the power bank with you regularly. Smaller, lighter power banks are more portable and easy to carry in a pocket or bag, but they usually have lower capacity. Larger power banks offer more capacity and features but can be bulkier and heavier. Consider how you plan to use the power bank and balance portability with capacity. If you need a power bank for travel or daily commutes, a compact and lightweight model may be more suitable.
Charging Speed (Input)Charging speed for the power bank itself, measured in watts (W), determines how quickly the power bank can be recharged. Faster input charging speeds mean less downtime between uses. Standard power banks typically recharge at 5W to 10W, while faster models can recharge at 18W or higher. If you frequently use your power bank and need it to be ready quickly, look for models with higher input charging speeds. Check the power bank's specifications to ensure it supports fast recharging if this is important to you.
Additional FeaturesAdditional features can enhance the functionality and convenience of a power bank. Some power banks come with built-in cables, eliminating the need to carry extra cables. Others have LED indicators to show the remaining battery level, which helps you know when it's time to recharge. Some models offer wireless charging capabilities, allowing you to charge compatible devices without cables. Consider which additional features are important to you and how they can improve your overall experience with the power bank.
