While not all power banks support pass-through charging, it is convenient to frequently charge multiple devices simultaneously. However, it’s important to note that some manufacturers advise against using pass-through charging due to potential overheating issues. Check the instructions and guidelines provided by the manufacturer before using this feature.

Another crucial consideration, especially if you frequently travel, is to be aware of airline restrictions on power bank capacity. Most airlines allow power banks with a capacity below 27,000 mAh to be carried in your carry-on luggage. However, it’s always a good idea to double-check with the specific airline you’re flying with to ensure compliance with their regulations.

To summarize, pass-through charging can be a handy feature for charging multiple devices simultaneously. However, always follow the manufacturer’s guidelines and recommendations to avoid potential risks. Additionally, be mindful of airlines’ power bank capacity restrictions when traveling to ensure a hassle-free journey.
