I'm looking to buy a battery pack that recharges itself fast, not the actual phone that is plugged into it. Something like the 140W LumoPack that charges enough in 3 minutes to completely charge a GS6, but hopefully cheaper (obviously don't expect something cheaper to be that fast). Looked on amazon and can only find things where "fast charging" seems to apply to the device and not the actual battery pack. I've found some highly rated ones that store like 10000mAh but they all take 8+ hours to charge up. If you know of any or own something that charges pretty quick then by all means share 
. Thanks.
