dremulatormadmax hiyou might have a 2 pin usb magnetic cable that means your phone or whatever you try to charge won't be able to communicate with the Power Bank test it by attaching the cable to your pc

dremulatormadmax youhave to remove the orange plastic cover of the minus side of the battery , it's put their so their are more logistic options available . it also protects the torch from being activated

dremulatormadmax theproduct is genuine i asked lumintop and they say their are different models

dremulatormadmax ithink that space is just for accessories (i'e pocket clip, 21700 battery in a protective case etc), as i don't believe you could safely use a single 18650 with so many leds, only a 21700

dremulatormadmax i agree on the not relying on the onboard charging circuit as i have the single cob version, and it charged my unprotected 18650 above 4.20 volts before the green light came on to say it was fully charged
