Can I convert AC to USB?
If your AC adapter has higher current rating it won’t destroy your device. You can certainly exceed the device voltage which is why his AC adapter should be 5V rated. USB is 500mA max but an unenumerated device can only draw 100mA.
Are USB adapters Safe?
Yes, outlets with USB ports are safe to use. Power output is reduced to 2.4 amps per USB port with 4.8 amps combined output across two USB ports. Some outlets have a lower combined output of 3.6 amps of combined output, which reduces the output in one port to 1.2 amps when both ports are in use.
What is a USB AC Adaptor?

Can a USB charger be used with an AC adapter?
The connector is universal and therefore it will work when used either way. It also outputs more power, as well as the theoretical output. There are also plenty of USB chargers that don’t fit into this specification, such as AC adapters.
Is it safe to use an AC adapter?
It can be safe, and it can be logical, but based on your description, it is neither. By “AC adapter” I am assuming you are talking about a regulated wall pack (wall wart, as some people say)… Every device has different power requirements: voltage level and current input.
Do you need a power adapter to charge an iPad?
When you need to charge your iPhone or iPad, we recommend that you use the USB power adapter and USB cable that came in the box with your device. These adapters and cables are also available separately from Apple and authorized Apple resellers. Customer safety is a top priority at Apple.
How many wires does an AC adapter need?
This information should be printed on a small sticker on the side of the AC adapter. The power requirements for your device should be in the operator’s manual. On top of that, a USB cable has at least 4 wires in it. A power cable typically only has 2, unless the AC adapter has additional sensor wires in it.
