The Anker Powercore II Ultra compact is on sale at Amazon for $22.65.. The slim was on sale yesterday and I missed it but hopefully this is smaller and better?
Anyone can compare? I have the regular powercore 20000mAh charger with 2 ports and have been using it for over a year. Works great but too big... Hoping this is nice small slim square size to put in my pocket and charges my phone even faster so I don't need to keep it plugged in. Don't forget their cables which imo are even better. Mainly starting being a fan from the cable and now chargers. Been using the same PowerLine II wire and already got it replaced easily.
