I'm Mel.
It is a 'smart' battery in that if the power draw is removed then the unit switches off. This i find useful as sending a power off command to the pi (via wifi) also switches off the battery.
I hear no degradation using this type of unit and would not move to anything else. I do have an Audiophinics linear psu but have not used it with the pi's since starting down the battery route.

Often the spec for kit in question will be over estimating what is required. I usually like to measure the actual current that the kit will take.
Also most Chinese power supplies over specify what you can actually get from them. The sellers presume that because it has a, say, 50VA transformer fitted then you can get V times A DC output power equalling 50, which you most definitely can't> There are losses associated with conversion from AC (the transformer rating) to DC (the output rating).
As a rule of thumb say 2/3 of the published current specification.
Thanks Alan
Sounds a bit complicated I will just buy a 5v 3a supply I think.
