Buying Guide

Everyone knows that laptop batteries are improving in all aspects, but it seems that it is still not enough, leading to the need for a power bank – a product that is very popular today. 

Here are the top factors to pay attention to get yourself a safe, secure charger that still provides the best experience:

  • When choosing to buy a backup battery for a laptop, you should choose a product with output voltage and currently express in volts (V) and amps (A). Because when charging a laptop, the output current needs to be larger than the charging current on the phone for effective charging. Therefore, choose to buy a power bank with a higher number of volts/amps than the parameters listed on your laptop charger.

  • Another criterion to choose to buy a laptop power bank is battery capacity. The larger the capacity, the more times you can charge the device, so if you want to charge your laptop many times or charge multiple devices at the same time, you should choose a capacity of 15,000mAh or more to meet.

  • Currently, to save time on charging laptop batteries, people often prioritize products with integrated fast charging mode. Therefore, you should prioritize products with more technology such as Power Delivery Technology, charging 2 cables at the same time, etc.

  • Obviously, you must ensure that your laptop can be plugged into your new portable charger. Examine the charger's inputs to check if it accepts a regular wall outlet connector, a USB-C port, or other universal solutions.

  • Finally, when choosing to buy a power bank for a laptop, you should prioritize products from leading brands to ensure the best quality.
