Can't I just plug the large magic box directly into the DC in on the battery pack to charge it? 0 Permalink Byron Izuka September 02, 2013 07:01 Anyone from HyperJuice with an answer to RS's question?... 0 Permalink Byron Izuka September 04, 2013 17:45 I got this from Angelo at HyperJuice support -- make sure you are using the correct male DC connector for your battery device: "The cable that's mounted on the Large Magic Box is only used for the first generation HyperJuice batteries. Since the battery you have require a higher voltage than the 1st gen batteries, you will have to use the other port using the 4inch cable which outputs the required voltage for the HyperJuice 1.5 or the HyperJuice 2 batteries." Aloha, Byron 0 Permalink Daryl Korvemaa May 25, 2014 11:32 Hi there. So If I understand this correctly, the HyperJuice 1.5 and 2 can be charged with the direct output of the MacBook charger? Reason being is that with my original HyperJuice, I got the Magic Box but on the MagSafe end of the cable, I soldered on a proper 2.5mm DC male connector so it is more solid. If the HyperJuice charges with the full output of the adapter, then it means I can simply remove the original Magic Box (which I understand is there for the purpose of being a 12v regulator for my current HyperJuice to charge) and solder on a simple DC female socket to reduce the size of the charger I have to carry around.Does that sound correct? If so, it sounds like time to upgrade to the HyperJuice 1.5 / 2. 0 Permalink LJ June 22, 2015 00:09 What if my MacBook Pro 15" Retina display late 2013 uses the MagSafe 2? Does the HyperJuice still work with it? 0 Permalink Please sign in to leave a comment.
