Is the Nighthawk M2 able to charge its battery during operation?

My biggest gripe about the Nighthawk M1 is its inablitity to charge up its own internal battery while being used — unless you place it on a block of ice, that is.

 

This is because it includes a temperature sensor, and if the battery gets warmer than about 42° Celsius not only does the charging stop, but under heavy traffic the battery will even get discharged. There are quite a few threads here in this forum about this problem.¹

Monitoring the battery temperature is a good thing in general, but for the M1 the threshold was clearly chosen too low; allowing e.g. 52° Celsius should still be perfectly safe — and much more practical.

 

So how about the M2? Does it charge while being used?

 

¹) Yes, it's a problem, because it makes the M1 impossible for mobile/nomadic scenarios where one e.g. uses it a home, plugs if off from the charger to commute to work, connects the charger back again at the office, and so on. It is possible to operate the M1 stationary with the battery removed, but that's not exactly what I buy a mobile router for.

  • M2 has same problem as M1 to charge the battery while using it as the temperature goes high very quick and that would stop charing the battery, suggest to buy a charger which can accommodate the battery, both for W-10(M1) and W-10A(M2).

      So am I correct in thinking that even if the battery fully discharges over time while plugged into a wall socket (which seems to be happening), it will continue to operate on mains power? We are a very small home office and I wouldn't describe us as heavy users, but until I saw this post couldn't figure out why the battery charge was diminishing even when plugged into mains power.

        when your battery is drained completely, suggest you to charge the battery with external charger as it will be taking long hours to re-charge it, if it still alive. When you have complete drained out battery inserted into M1/M2, it might still able to re-charge but that would take longer hours, even longer than external charger, as you are using the machine while charging it.
