It looks like a useful device for backup IF IT DOES WHAT IT SAYS. The NRMA should do a test and report on it. BUT they do say "satisfaction guaranteed" in their add !
It probably has a lithium battery of 12 ahr capacity. If so it probably will be good and work well without failing in a short time, if the quality is OK. The electronics for the various outputs is the usual question of quality.
The fact that the description is written by advertising people and leaves out important facts is not inspiring however. eg "Dimensions: 8 x 18 cm" x ??? You could individually buy some other devices to do those jobs, and probably better, but they would be a lot bigger !
Your money, your choice !

These devices have been around for a couple of years now, and they are typically built around a 14,000 or 15,000 mah lithium ion battery, which is very well suited to the job. They can normally deliver around 400a cranking, and have very low self discharge rates.
I believe it would be a good thing to have tucked away, preferably connected so the trickle charger can keep it charged until the day you need it.
I intend to have one in the kit, but not at NRMA prices, a bit of research and patience should see you with one for half the price delivered.
There's a number of these around and our laptop runs on 19v and is charged from the 12v house batteries. This one is the same as the schneider, cheaper and comes with the bits you may need.
