GL-AR300MD - need a power adapter?

Please use a 5V2A power adapter for this.</blockquote>

Or it can work from USB?

It works from 5V 1A USB adapter. But some adapter cannot really reach 1A specs, so we recommend 2A adapter.

It should work from 2 x USB with a “dual” adapter.

Hi there. Just to confirm. If I use a 240V Samsung phone wall power charger (usual set up: wall (@240V) - USB cable - phone) - it is rated as 5V/2A. That won’t be too much for the AR300M?
Thanks for your time.

This is a perfect power adapter for AR300M.

To clarify this, even if you have a 5V 5A Adapter , the router only uses the current it needs and not more.
