I have an iPhone 6 and I think the PowerIq portable charger would be the best fit because it detects what kind of device you are using so that it can charge faster than other powerbanks
What phone do you have and which accessories would be a good fit for your device?
I also have an iPhone 6 and I agree with you. Another good accessory is the PowerPort 2 which isn’t phone specific but is helpful when you need to charge two things.
Powercore Slim to get a full recharge away from mains power, Powerport 2 to recharge your phone and your Powercore Slim and the respective cables (micro+ whatever your phone needs).
i have the 6+ and I love the Anker Charger. Fastest charge I have had.
Apple iPhone 7 Plus - I use the Powercore Slim 5000 when travelling purely for size, as no battery cases (by Anker) for 7+?
