right after Astro-Knights, the 10th island it's going to take a long time, as Astro-Knights will come out in late spring
If you have already checked the connections on the battery I would suggest testing the alternator and the battery. If the battery will not take a charge or the alternator will not give a charge you could have similar problems.
at least 10 hours after full charge
24 hr.
It takes about the whole night to charge completly
It should take roughly 1-3 hours to charge the batteries in a hoverboard.
4 hours
overnight
It shouldn't take long, you have to plug it into Itunes first and it should already have some charge at first!
Not Long about 2 hours
depends on you charge rate. if you are charging at 1.1A (1100mA) it will take 1 hour
It took 4.3 hours
