Moonstone 6000mAh external battery (green only) now use coupon code DRIAP3DA reduce its price from £21.99 to £14.99
Got this email offer direct worth sharing as it looks a good price for a well made high performance battery.
Will be checking it out soon when mine arrives!!
I have some experience with Other brands of External batteries and what strikes me as different with this brand is the lipo battery promising a higher more efficient transfer of reserved energy.
Anyway even Liion would be a good price for a good brand so will try and update when I learn more about quality but their website looks promising
