This one still remains a mystery.
As per the comment on Amazon
When I first looked at the Elite vs non-Elite Powerport2, they were different shapes but the same total volume, I thought it odd at the time. Then I see later a revision and the @TechnicallyWell review and see the Elite is bigger. This is even odder. Why they make it bigger? It doesn't seem electronically upgraded in any way? I can only infer its more drop-tested better? It appears to be lighter? Reduced from 4.8oz to 3.36oz. Is that true?
It would indeed be more durable if they made it lighter in weight and larger as the force would be spread over more material.
However for me, it is a step backwards. I carry a 12W Aukey as my backup, it is weaker than Anker Powerport2 but it covers in me in case of issues (broken, etc). So the Elite is even less likely to be carried, if anything it might make me carry the Powerport4 more often. I consider the Aukey a backup because it is so small and gets so hot, I'm guessing it won't last long, I rely on Anker as my primary, they very rarely fail.
PowerIQ2 should be now and should be making things smaller / more powerful.
As winner of the giveaway, i'll have it in the next few weeks.
Edit: i see Anker saying its mostly due avoid the spark issue?
What sparking problem?
