Which router uses less power: AR300m or MT300N-V2?

According to the product pages AR300m uses < 2 Watts while MT300N-V2 uses < 2.75 Watts, but I am skeptical because AR300m has a faster processor.

The use case would be 4g modem use with WG client active and low transmit power private Wifi (no guest network) running, in case that also matters.

The datas was tested and provided by the R&D personnel of GL iNet,So you can trust it.

Nice, so the best mini router for traveling is Shadow then, since it is both faster and uses less battery than Mango. And it also has much more space for installing additional packages.
