Common questions about C7 cords and power banks

Can I use an IEC C7 extension cord with a power bank?

A power bank itself typically charges from a USB-C cable, not a C7 cord. The C7 extension cord is designed for HyperJuice USB-C GaN chargers (70W, 100W, or 145W). It lets you connect the charger to a wall outlet from farther away, which can be useful if the outlet is hard to reach. The power bank then connects to the charger via USB-C. So the C7 cord is part of the charging setup, not a direct power bank accessory.

What is a C7 power cord used for?

The C7 cord (often called a figure-8 cord) connects a device with a C7 inlet to a wall outlet. In the HyperJuice lineup, it works with the 70W, 100W, and 145W USB-C GaN chargers. Using the cord with the included C8 adapter lets you create a desktop charging station with more secure attachment to the wall plug and extended reach.

What is the difference between an IEC C7 and C5 cord?

Both are IEC connectors, but they are not interchangeable. The C7 is a figure-8 connector with two pins, while the C5 is a three-pin connector often called a Mickey Mouse connector. The HyperJuice C7 Extension Power Cord is specifically for the 70W, 100W, and 145W HyperJuice USB-C GaN chargers. Do not assume a C5 cord will fit your charger; check the inlet on your device.

What does 'figure-8 power cord' mean?

Figure-8 refers to the shape of the C7 connector, which looks like the number 8. It is a standard IEC connector used on many small electronics. The HyperJuice C7 Extension Power Cord uses this connector to plug into the charger's C8 inlet (via the included C8 adapter).

When would I need a C7 extension cord instead of the standard cord?

If your wall outlet is far from where you want to place your charger, or if you want a more secure connection at the wall plug, the C7 extension cord can help. It is also useful for creating a dedicated charging station on a desk, especially when paired with the C8 adapter that comes with the charger.

What the C7 cord does not do

The C7 extension cord is not a power bank accessory in itself; it does not connect directly to a power bank. It is also not a universal cord for all chargers. The supplied information only confirms compatibility with the HyperJuice 70W, 100W, and 145W USB-C GaN chargers. If you have a different charger, check its inlet type before assuming the C7 cord will fit.

Additionally, the cord does not change the charging speed or capacity of your power bank. It simply extends the physical reach between the wall outlet and your charger.
