Power banks andUSB-Chubs are two convenient but vastly different gadgets.
However, they share something in common: pass-through charging.
Here’s why it matters and how it can be helpful to you.

Essentially, the unit connected to the wall outlet lets power pass through it to charge the other devices.

In all its implementations, the primary benefit of pass-through charging is convenience.

For example, ports are scarce on many modern laptops.
All other ports on your laptop remain free for connecting to other devices.
And both devices will get charged simultaneously.
The Zendure 10000mAh Mini Power Bank is an excellent portable charger that supports both Qualcomm Quick Charge and USB PD fast charging protocols.
How Does Pass-Through Charging Work?
As mentioned, pass-through charging is typically available in power banks and USB-C hubs.
However, as these two are very different devices, the implementation of the pass-through charging is also different.

Otherwise, while the hub may work, it won’t charge the connected rig.
But for the pass-through charging to work correctly, it requires a 90W power supply.
Are There Any Downsides?
Pass-through charging is a handy feature on both power banks and USB-C hubs.
But it’s not perfect, particularly on power banks.
And more heat can reduce the lifespan of the battery.
The feature is also not as energy-efficient as directly charging your equipment from a wall adapter.
Some power bankseven limit the outputto the connected gear.
Do All Power Banks or USB-C Hubs Have It?
Unfortunately, pass-through charging is not available on all power banks.
It’s comparatively more common in USB-C hubs or docking stations.
Not all support it, though, probably because of the extra cost involved in implementing USB-PD technology.
All-in-all, pass-through charging is a helpful feature that makes life convenient on every machine that supports it.
