Q. What is the MAX Adapter and how do I use it?

The MAX Adapter is a state-of-the-art cellular modem by Peplink, it is not a standalone router. It can be used in two ways to:

Add an additional cellular WAN to your existing Peplink device which has a USB WAN port. Provide 5G or LTE connectivity (depending on your model) to your Windows or Linux devices on-the-go, acting as a cellular modem.

Q. Is the MAX Adapter right for me?

Are you in need of a solution that can add an additional 5G/LTE WAN to existing Peplink products via a USB WAN port, supports PepVPN, offers external antenna support, has dual SIM slots, and is something small but not a full router? Then the MAX Adapter is for you!

Q. Do antennas come included?

Four LTE antennas are included but the GPS antenna must be purchased separately.

Q. Can I pair my MAX Adapter with my Mac?

Currently, our MAX Adapter is only compatible with Windows & Linux devices.

Q. Does the MAX Adapter have a built-in battery?

No, the MAX Adapter is powered via USB-C.

Q. My MAX Transit has a USB port but it’s not compatible with the MAX Adapter. Why?

The MAX Transit’s USB port only provides power input, not data. For compatibility, the device must contain a USB WAN port.
