What is Pass Through Charging



Pass through charging is when a power bank has the ability to charge itself and charge devices at the same time. It’s very helpful if you always want your power bank to be at full capacity. This way, when you do need to go mobile, your power bank is fully charged, your device is charged and you can be prepared for when you need your power bank the most since it’s at full capacity.

Do all power banks have Pass Through charging?

No, unfortunately not all power banks have Pass-through charging simply because it’s actually a charging design that can be rather unsafe. It can be unsafe because the power bank is charging and recharging at the same. Since the power bank must charge a device, it’s sending a current outward and that creates energy, which as a result creates heat. Then the charger is recharging itself at the same time which is sending a current into the power bank.

Power banks tend to lose their power capacity due to the recharging and discharging of their batteries. Charging a device already makes the battery lose capacity quite slowly but with Pass Through charging, the power bank is heated up even more and using, even more, energy to exhaust the battery. In the short-term, Pass-Through charging can be very convenient but in the long-term, it can harm a power bank’s capacity quite a lot. At the same time, the output charging speed of the power bank may be lowered during Pass Through charging since the power bank has to focus some its power to another source.

Which Power Banks Support Pass Through Charging?

Although not all power banks support Pass Through charging there’s still quite a few power banks that do support it. If you’re searching for a power bank that is able to do Pass Through charging then we recommend a portable charger with a high capacity because this way, if the power bank’s battery does begin to deplete, it will still be at a good power capacity. To truly know if the power bank is Pass Through charging there won’t be a blatant way to know because even electronic charging companies that produce power banks really don’t users to use the feature. However, if you ask, they will happily answer if it is capable of doing it or not.

Ultimately, we think that Pass-Through charging is double edged. It’s a great way to keep all your devices charged in the short-term. In the long-term, however, the power bank will be damaged quite a lot. We may recommend getting a high capacity power bank for Pass Through charging, but we HIGHLY recommend to not use Pass-Through charging too much or not at all; Since the power bank will wear down, heat up and increase the chance of your device that’s being charged, to get damaged. Also, you’ll be in the market for getting another power bank, so Pass Through charging can make you spend more money unnecessarily.

It’s your choice. We’ve told you the benefits and consequences of Pass Through charging.
