What about 5.2amp mobile charges?Cloupor can't be trusted when it comes to build quality or output specs, they still have a fanbase for some bizarre reason.
The sigelei's are worth considering if you're looking for 100 watt+ mods - don't know if the USB charge function is a viable prospect when it comes to dual 18650 mods. Balancing the batteries is easy enough but the amp levels of the available USB charge boards would mean a super long charge time.
