FAQ

Because some devices need a stronger electrical current than others to charge, you might notice a marked difference in charging speed. A smartphone, for instance, can charge properly on 1 amp of current, while a tablet requires over double that (2.1 amps).

Charging your tablet with a smartphone charger means it’s only getting half the current it needs—and you’ll wait hours for a full charge. Do the opposite, and you’ll find your smartphone charges much more quickly than usual.

Chargers are built to provide just the right amount of electrical current (measured in amps). And the devices themselves are designed to draw only the current they need and cut off the flow when the battery is full. This stops the devices from overheating or suffering any damage.
