If the issue persists, do contact us. 

Why the charger charges my device slowly? 

 

Check to ensure that the cable you are using to charge is the original cable that came with your 
device or a (MFI) certified cable. 

 

Check to ensure that the total input current required by your devices is not higher than 4A. 

If the issue persists, do contact us. 
 
My device charges at 1 Amp, will this charger’s 4 Amp output harm it? 
No, the charger will only supply the maximum charge current allowed by your device up to 2.4 Amps 
from each port. That is to say, if you use a 2.4A charger with a device drawing 1A, it will only draw 1A.
