There seems to be something off with the capacity as well. It charged my tablet from 0 - 80% before switching off, whilst my other 10k charger charged to 100 and had 10% left in the tank. I'm guesstimating that the actual capacity is 8000mAh or lower. If you crank it open I wouldn't be surprised to find two 4000mAh cells
This one did to 80% I think before conking out, supplying around 5,600mAh (7000mAh * 80% = 5600mAh). Even with an efficiency rating of 80%, that gives a true battery capacity of 7000mAh Vs the advertised 10000mAh.
tl;dr, many manufacturers lie about the capacity of their batteries, and I think this is one that is lying. See this video for examples of battery packs that are / are not lying about their actual capacity. youtu.be/xR-…Am0
