Question: is 2.4 amp charger good?
Answer: High Amp Output A good charger would provide you with at least 2.1 Amps (or 2100 mA) per USB port. ... So if you're looking for a high-speed dual USB car charger, you want to look for a 4.8A USB car charger. This means that each USB port provides 2.4 Amps, which is more than sufficient to charge two iPads simultaneously.
