I know it's maybe to soon, but I'm looking for an external battery for my soon to come rMacbook. I want one that can has the most juice.

I know that there's the Anker Astro E7 (79$) that can can charge iPhone 6 10x and iPad Air 2x....(guessing it should be able to charge the MacBook 1x at least?)

Do you guys know any other batteries?

I have both rMB and Anker Astro E7 Ultra-High Capacity 25600mAh

Astro E7 not only charges slow but it drains the battery very quick. It looks like the voltage keeps fluctuating.

It charges right now about between 3.4W and 7.4W vs. 29W (standard USB-C charge). I will get the usb amp meter to do some additional tests.

The idea is right, just the implementation is crap so far. Having a power brick that could recharge laptop 4-5 times would be great.

rMacbook battery has only 5263 mAh battery
