I bought myself one of those portable batteries to charge my phone and tablet on the go. It always seems like when I charge my Nexus 5 from the wall charger the battery lasts longer than when I do it from my car usb, or the portable battery itself. I could get 90% from the wall charger and get to 90% from the portable battery and the latter seems to drain faster. Am I just am I imagining things?

The problem with using a battery pack is that you are filling up with poor quality electricity. If you charge from the wall you know exactly where it has come from, kind of like fair trade organic apples

is it possible that when you top up when out and about, you are more likely to be using your device a bit heavier (more screen-on or active time), while wall charger implies charging at home therefore implies using device a bit less?
