There’s nothing more inconvenient than realizing your laptop is nearly dead when you’re trying to get work done offsite. Laptop power banks offer a solution to this problem, providing a portable way to recharge your devices. These power banks come with larger capacities and more ports compared to regular rechargeable banks, making them suitable for charging laptops.
When looking for a laptop power bank, it’s important to consider the capacity. A power bank with a capacity between 20,000 and 27,000 mAh is ideal for delivering enough power to a laptop. Going above 27,000mAh may restrict you from carrying it on an airplane, as most airlines have restrictions on the maximum capacity allowed in carry-on luggage. It’s also important to note that the listed capacity of a power bank may not directly translate to the actual charge delivered to your devices due to differences in voltage and energy conversion.
In terms of ports, most large power banks come with at least three USB ports, including a mix of USB-C and USB-A ports. Some ports may supply power at different wattages, so it’s essential to choose the right port for optimal charging speeds. Additionally, some power banks may include AC ports, but it’s recommended to use these only for devices that can’t use USB to avoid energy wastage through conversion.
Wireless charging capabilities in power banks have improved over the years, offering fast and convenient charging options, especially for devices like Samsung Galaxy phones. However, wired connections are generally more efficient for charging. When it comes to design, laptop-compatible power banks are bulkier and heavier than regular power banks, with features like displays to indicate battery charge levels.
To test portable laptop chargers, various power banks with capacities of at least 20,000mAh were considered. These power banks were tested with different devices, including smartphones and laptops, to evaluate their charging capabilities, portability, durability, and overall design.
Overall, when choosing a laptop power bank, it’s essential to consider factors like capacity, port options, design, and charging efficiency to ensure you have a reliable portable charging solution for your devices.
