How long will the batteries last in my hotspot?

Battery life depends on how hard you use it of course but you can expect many hours out of the hotspot before it has to be charged up again.  Charging is easy – just like a cell phone – plug in the included cord and it will charge the battery until it is full.  You can also use it while it is plugged in and lots of folks just keep it plugged in and active until they need to take it somewhere.  You can also use a portable battery charger to plug it in and charge it while you are on the go.  It will also charge through with a car charger or anywhere else you can plug in the usb cord.
