Initially there will be no additional cost for the basic level service. We might offer a premium version down the road. Still defining coverage but aiming to have a practical global coverage. The battery's capacity is 10,000 milliamps per hour. Yes, there are many hacks you can do to achieve a similar tracking ability. We want to provide a comprehensive solution in which the location tracking is just a part of it.

"37 Watts lithium ion battery" is meaningless as a capacity.

As is "10,000 milliamps per hour".

You likely have a 10 amp hour, 3.7 volt battery yielding a capacity of 37 watt hours. This is about the same capacity as an ordinary smart-phone (perhaps a bit larger, I think an iphone is 5 or 10ish ).

10,000 mah is the same as 10 amp hour. And that is 6 times what an iPhone has actually

Those units are very different from milliamps per hour (which is basically a nonsense unit) and watts (which are a unit of energy per time, therefore saying nothing about how long the battery will last).

I'm just trying to address the confusion here. Battery capacity is a relatively mundane detail, and I don't necessarily expect the people writing marketing copy to understand electrical terminology.

Yeah iphones are pretty small. I seem to remember some of my Sammys and Motos having in the 9-12 range. 37 might actually be approaching some small netbooks.

The capacity for energy storage is volts * amps over time. So a 10 amp hour battery at 3.7v holds less energy than a 10 amp hour battery at 12v. Together it makes watt-hours. That's the best way to measure storage capacity.
