As promise, I’m looking for MR-3040 information about autonomy. This device is really interesting as it provides an internal battery to power the device on. The question was, how many time can we use it, is the autonomy good enough to have a real mobile device you don’t have to care about autonomy when bring out to public !

The first thing is to reload the battery, from 0 to 100% it takes 3:10 using the given equipment.  The next thing is to empty the battery by just doing nothing else than switch it on, as a result, the MR-3040 ran during 7hours. This is a really good result as it means that we can bring it out most of one day (or night).

The last step is to empty the battery transferring file from & to to mr3040, in this scenario, the battery autonomy should be smaller but the result is an autonomy of 5 full hours with a transfer rate about 1.5MB/s. I was expecting a shorter time so it is a good news.

The main issue I can raised after this test is the coverage area of these kind of devices (MR3040 or MR3020) really limited to a some meters and really blocked by rock walls. This is limiting the share with the neighborhood capability. It makes it more recommended to have a share into a room.
