xomo 255s gt laser

Hey i want to ask something.I leave my Xomo for 3 and half weeks i didn’t charge or vape it cause i forgot to bring it.and now i try to charge it it’s been like 4 days it doesn’t fully charge.can you answer me how many days it will be full and i can vape it like before.i just bought it last 2 month

Does anybody know how I can tell my zomo 255S gt laser is fully charged? I am charging it at 5 volts and 1.0 amp as per the instruction manual. The LED charging indicator goes from flashing red to flashing blue to flashing green. It does not say what will happen when fully charged. Manual...
