Interesting. How long do they sustain a wi-fi device without recharging?
Hard to say exactly how long they would last, but we have very good results. We will run a Linksys access point, a laptop, and a 4 port battery charger (for Motorola handheld computers) off of one and can run all day (8 hours) and still have over 1/4 charge left. We always have a spare battery on-hand but to my knowledge have never needed it. Note that the type of access point does make a difference... we originally looked at using larger Cisco access points, not because we wanted to but because we had them, but found that the current draw was significantly higher (likely due to cooling fans, etc).
The VML isn't what enabled us to do this, as we used to do it occasionally with a deep cycle battery and inverter, but the VML is convenient enough that we can do it more often. We have a number of locations that will use these and it's not practical to ship the DC battery, but these can obviously be shipped easily.
