Nighthawk m1 shuts down

[Pt1936]

Using  in a motorhome in storage off 5v usb supply. After about 4 days unit shuts down. Only way to restart is to remove battery then attach to power. Unit only a few months old. Battery is fully charged.

The power supply converts to DC power anyway.

If you have it on constant ac power, it shouldn't have the battery in it.

Hi. Yes I’m aware of that, but there isn’t a 240v supply in the motorhome, works off solar and 12v batteries. I’ve plugged it into usb without battery. See what happens. Thanks

Seems to be ok plugged into usb power supply once battery removed. I had a different mifi unit in previously, that worked with battery in when left permanently plugged into usb. Thanks for your suggestion, I would not have thought about removing the battery as seems unusual!
