I've seen these around quite a bit. Seem to be a generic box with different branding. Although cannot say if the internals are different. Something as was advertised is that you could charge the unit at the same time drawing power. Sadly what I found that it was only partly true. The charging part would cease after a period of time or when the battery became full. So you could be unaware you are discharging the battery even when connected to the mains.
